當鍵盤出現在 iOS 中時向上移動 UIView

Question

我有一個 UIView，它不在 UIScrollView 里面。 當鍵盤出現時，我想向上移動我的視圖。 在我嘗試使用此解決方案之前： 當鍵盤存在時，如何使 UITextField 向上移動？ .

它工作正常。 但是在文本字段中插入數據后，它把我帶到另一個視圖，當我回到這個頁面時，它只是跳躍，我看不到我的文本字段。 這個問題有沒有更好的解決方案？

Answer 1

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}

#pragma mark - keyboard movements
- (void)keyboardWillShow:(NSNotification *)notification
{
    CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    [UIView animateWithDuration:0.3 animations:^{
        CGRect f = self.view.frame;
        f.origin.y = -keyboardSize.height;
        self.view.frame = f;
    }];
}

-(void)keyboardWillHide:(NSNotification *)notification
{
    [UIView animateWithDuration:0.3 animations:^{
        CGRect f = self.view.frame;
        f.origin.y = 0.0f;
        self.view.frame = f;
    }];
}

Answer 2

使用以下代碼來顯示和隱藏鍵盤

//Declare a delegate, assign your textField to the delegate and then include these methods

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil];
    return YES;
}


- (BOOL)textFieldShouldEndEditing:(UITextField *)textField {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHide:) name:UIKeyboardDidHideNotification object:nil];

    [self.view endEditing:YES];
    return YES;
}


- (void)keyboardDidShow:(NSNotification *)notification
{
    // Assign new frame to your view 
    [self.view setFrame:CGRectMake(0,-110,320,460)]; //here taken -110 for example i.e. your view will be scrolled to -110. change its value according to your requirement.

}

-(void)keyboardDidHide:(NSNotification *)notification
{
    [self.view setFrame:CGRectMake(0,0,320,460)];
}

Answer 3

我在UIView上寫了一個小類別，它可以管理臨時滾動的東西，而無需將整個東西包裝到UIScrollView 。 我在這里使用的動詞“滾動”可能並不理想，因為它可能會讓您認為涉及到滾動視圖，而實際上並沒有——我們只是在為UIView （或UIView子類）的位置設置動畫。

其中嵌入了一堆適合我的形式和布局的神奇數字，但可能不適合您的形式和布局，因此我鼓勵對其進行調整以滿足您的特定需求。

UIView+FormScroll.h：

#import <Foundation/Foundation.h>

@interface UIView (FormScroll) 

-(void)scrollToY:(float)y;
-(void)scrollToView:(UIView *)view;
-(void)scrollElement:(UIView *)view toPoint:(float)y;

@end

UIView+FormScroll.m:

#import "UIView+FormScroll.h"


@implementation UIView (FormScroll)


-(void)scrollToY:(float)y
{

    [UIView beginAnimations:@"registerScroll" context:NULL];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.4];
    self.transform = CGAffineTransformMakeTranslation(0, y);
    [UIView commitAnimations];

}

-(void)scrollToView:(UIView *)view
{
    CGRect theFrame = view.frame;
    float y = theFrame.origin.y - 15;
    y -= (y/1.7);
    [self scrollToY:-y];
}


-(void)scrollElement:(UIView *)view toPoint:(float)y
{
    CGRect theFrame = view.frame;
    float orig_y = theFrame.origin.y;
    float diff = y - orig_y;
    if (diff < 0) {
        [self scrollToY:diff];
    }
    else {
        [self scrollToY:0];
    }

}

@end

將它導入你的 UIViewController，然后你就可以了

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    [self.view scrollToView:textField];
}

-(void) textFieldDidEndEditing:(UITextField *)textField
{
    [self.view scrollToY:0];
    [textField resignFirstResponder];
}

...管他呢。 該類別為您提供了三種非常好的調整視圖位置的方法。

將視圖綁定到鍵盤也是一個選項（請參閱答案底部的 GIF）

使用擴展：（未完全測試）

extension UIView{
    func bindToKeyboard(){
        NotificationCenter.default.addObserver(self, selector: #selector(UIView.keyboardWillChange(notification:)), name: Notification.Name.UIKeyboardWillChangeFrame, object: nil)
    }

    func unbindToKeyboard(){
        NotificationCenter.default.removeObserver(self, name: Notification.Name.UIKeyboardWillChangeFrame, object: nil)
    }
    @objc
    func keyboardWillChange(notification: Notification) {
        let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
        let curve = notification.userInfo![UIKeyboardAnimationCurveUserInfoKey] as! UInt
        let curFrame = (notification.userInfo![UIKeyboardFrameBeginUserInfoKey] as! NSValue).cgRectValue
        let targetFrame = (notification.userInfo![UIKeyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
        let deltaY = targetFrame.origin.y - curFrame.origin.y

        UIView.animateKeyframes(withDuration: duration, delay: 0.0, options: UIViewKeyframeAnimationOptions(rawValue: curve), animations: {
            self.frame.origin.y+=deltaY

        },completion: nil)

    }
}

使用擴展名：

extension UIView{
    func bindToKeyboard(){
        NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(UIView.keyboardWillChange(_:)), name: UIKeyboardWillChangeFrameNotification, object: nil)
    }


    func keyboardWillChange(notification: NSNotification) {

        let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
        let curve = notification.userInfo![UIKeyboardAnimationCurveUserInfoKey] as! UInt
        let curFrame = (notification.userInfo![UIKeyboardFrameBeginUserInfoKey] as! NSValue).CGRectValue()
        let targetFrame = (notification.userInfo![UIKeyboardFrameEndUserInfoKey] as! NSValue).CGRectValue()
        let deltaY = targetFrame.origin.y - curFrame.origin.y


        UIView.animateKeyframesWithDuration(duration, delay: 0.0, options: UIViewKeyframeAnimationOptions(rawValue: curve), animations: {
                self.frame.origin.y+=deltaY

        },completion: nil)

    }  
}

用法：

// view did load...
textField.bindToKeyboard()

...

// view unload
textField.unbindToKeyboard()

結果：

我發現theDuncs 的回答非常有用，您可以在下面找到我自己的（重構）版本：

---

主要變化

1. 現在動態獲取鍵盤大小，而不是硬編碼值
2. 將 UIView 動畫提取到它自己的方法中以防止重復代碼
3. 允許將持續時間傳遞給方法，而不是硬編碼

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}

- (void)viewWillDisappear:(BOOL)animated {

}


- (void)keyboardWillHide:(NSNotification *)notification {

}


- (void)moveFrameToVerticalPosition:(float)position forDuration:(float)duration {
    CGRect frame = self.view.frame;
    frame.origin.y = position;

    [UIView animateWithDuration:duration animations:^{
        self.view.frame = frame;
    }];
}

Answer 6

基於 Daniel Krom 的解決方案。 這是swift 3.0 中的版本。 與AutoLayout配合使用效果很好，並在鍵盤出現時移動整個視圖。

extension UIView {

    func bindToKeyboard(){
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillChange), name: NSNotification.Name.UIKeyboardWillChangeFrame, object: nil)
    }

    func unbindFromKeyboard(){
        NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillChangeFrame, object: nil)
    }

    @objc
    func keyboardWillChange(notification: NSNotification) {

        guard let userInfo = notification.userInfo else { return }

        let duration = userInfo[UIKeyboardAnimationDurationUserInfoKey] as! Double
        let curve = userInfo[UIKeyboardAnimationCurveUserInfoKey] as! UInt
        let curFrame = (userInfo[UIKeyboardFrameBeginUserInfoKey] as! NSValue).cgRectValue
        let targetFrame = (userInfo[UIKeyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
        let deltaY = targetFrame.origin.y - curFrame.origin.y

        UIView.animateKeyframes(withDuration: duration, delay: 0.0, options: UIViewKeyframeAnimationOptions(rawValue: curve), animations: {
            self.frame.origin.y += deltaY
        })
    }  
}

如何使用它：在viewDidLoad添加bindToKeyboard函數，如：

override func viewDidLoad() {
    super.viewDidLoad()

    view.bindToKeyboard()
}

並在 deinit 中添加unbindFromKeyboard函數：

deinit {
    view.unbindFromKeyboard()
}

        )
    }

    func unbindToKeyboard() {

        let targetFrame = (notification.userInfo![UIResponder.keyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
        let deltaY = targetFrame.origin.y - curFrame.origin.y

        UIView.animateKeyframes(withDuration: duration, delay: 0.0, options: UIView.KeyframeAnimationOptions(rawValue: curve), animations: {
            self.frame.origin.y += deltaY
        })

        {
            CGPoint scrollPoint = CGPointMake(0.0, self.frame.origin.y - (keyboardSize.height - self.frame.size.height));
            [[self getTableView] setContentOffset:scrollPoint animated:YES];
        }
    }

-(void) keyboardDidHide: (NSNotification *)notif

    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    [self getTableView].contentInset = contentInsets;
    [self getTableView].scrollIndicatorInsets = contentInsets;
}

基於theDunc 的回答，但使用自動布局用 Swift 編寫。

@IBOutlet weak var bottomConstraint: NSLayoutConstraint! // connect the bottom of the view you want to move to the bottom layout guide

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    NSNotificationCenter.defaultCenter().addObserver(self,
                                                     selector: #selector(ConversationViewController.keyboardWillShow(_:)),
                                                     name: UIKeyboardWillShowNotification,
                                                     object: nil)

    NSNotificationCenter.defaultCenter().addObserver(self,
                                                     selector: #selector(ConversationViewController.keyboardWillHide(_:)),
                                                     name: UIKeyboardWillHideNotification,
                                                     object: nil)
}

override func viewWillDisappear(animated: Bool) {
    NSNotificationCenter.defaultCenter().removeObserver(self, name: UIKeyboardWillShowNotification, object: nil)
    NSNotificationCenter.defaultCenter().removeObserver(self, name: UIKeyboardWillHideNotification, object: nil)
    super.viewWillDisappear(animated)
}

// MARK: - Keyboard events

func keyboardWillShow(notification: NSNotification) {
    if let userInfo = notification.userInfo,
        keyboardFrame = userInfo[UIKeyboardFrameBeginUserInfoKey]
    {
        let keyboardSize = keyboardFrame.CGRectValue().size
        self.bottomConstraint.constant = keyboardSize.height
        UIView.animateWithDuration(0.3) {
            self.view.layoutIfNeeded()
        }

    self.bottomConstraint.constant = 0
    UIView.animateWithDuration(0.3) {

    }
}

Answer 11

我已經實現了一個自定義控制器，它動態計算鍵盤的大小，在出現和消失時滾動 textFields，即使在設備旋轉期間也是如此。 適用於所有 iOS 設備。 只需簡單地繼承控制器即可擁有您需要的東西。 您可以在以下鏈接中找到所有說明： https : //github.com/mikthebig/ios-textfield-scroll

Answer 12

無需添加觀察者通知的簡單解決方案

-(void)setViewMovedUp:(BOOL)movedUp
{
    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:0.3]; // if you want to slide up the view

    CGRect rect = self.view.frame;

    if (movedUp)
    {
        // 1. move the view's origin up so that the text field that will be hidden come above the keyboard
        // 2. increase the size of the view so that the area behind the keyboard is covered up.
        rect.origin.y -= kOFFSET_FOR_KEYBOARD;
        rect.size.height += kOFFSET_FOR_KEYBOARD;
    }
    else
    {
        // revert back to the normal state.
        rect.origin.y += kOFFSET_FOR_KEYBOARD;
        rect.size.height -= kOFFSET_FOR_KEYBOARD;
    }
    self.view.frame = rect;

    [UIView commitAnimations];
}


-(void)textFieldDidEndEditing:(UITextField *)sender
{
     if  (self.view.frame.origin.y >= 0)
        {
            [self setViewMovedUp:NO];
        }
}

-(void)textFieldDidBeginEditing:(UITextField *)sender
{
        //move the main view, so that the keyboard does not hide it.
        if  (self.view.frame.origin.y >= 0)
        {
            [self setViewMovedUp:YES];
        }
}

在哪里

#define kOFFSET_FOR_KEYBOARD 80.0

Answer 13

干得好。 不過，我已將此代碼與 UIView 一起使用。 您應該能夠對滾動視圖進行這些調整。

    func addKeyboardNotifications() {
        NotificationCenter.default.addObserver(self,
                                               selector: #selector(keyboardWillShow(notification:)),
                                               name: NSNotification.Name.UIKeyboardWillShow, object: nil)
        NotificationCenter.default.addObserver(self,
                                               selector: #selector(keyboardWillHide(notification:)),
                                               name: NSNotification.Name.UIKeyboardWillHide, object: nil)
    }

    func keyboardWillShow(notification: NSNotification) {

        if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
            let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
// if using constraints            
// bottomViewBottomSpaceConstraint.constant = keyboardSize.height
self.view.frame.origin.y -= keyboardSize.height
            UIView.animate(withDuration: duration) {
                self.view.layoutIfNeeded()
            }
        }
    }
    func keyboardWillHide(notification: NSNotification) {

        let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
//if using constraint
//        bottomViewBottomSpaceConstraint.constant = 0
self.view.frame.origin.y = 0
        UIView.animate(withDuration: duration) {
            self.view.layoutIfNeeded()
        }
    }

不要忘記在正確的位置刪除通知。

func removeKeyboardNotifications() {
    NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillShow, object: nil)
    NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

以防萬一有人在Swift 中尋找解決方案，請將其放入您的代碼中：

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(notification:)), name: .UIKeyboardWillShow, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(notification:)), name: .UIKeyboardWillHide, object: nil)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    NotificationCenter.default.removeObserver(self, name: .UIKeyboardWillShow, object: nil)
    NotificationCenter.default.removeObserver(self, name: .UIKeyboardWillHide, object: nil)
}


@objc func keyboardWillShow(notification: Notification) {
    if let userInfo = notification.userInfo {
        if let keyboardSize = (userInfo[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
            UIView.animate(withDuration: 0.3) {
                var alteredFrame = self.view.frame
                alteredFrame.origin.y = -keyboardSize.height
                self.view.frame = alteredFrame
            }
        }
    }
}

@objc func keyboardWillHide(notification: Notification) {
    UIView.animate(withDuration: 0.3) {
        var alteredFrame = self.view.frame
        alteredFrame.origin.y = 0.0
        self.view.frame = alteredFrame
    }
}

Answer 16

如果該textfield位於表格的單元格中（即使table.scrollable = NO ），也可以輕松自動textfield 。

注意：桌子的位置和大小必​​須合理。 例如：

• 如果 table 的 y 位置從視圖底部算起 100，那么 300 高的鍵盤將與整個 table 重疊。
• 如果表的height = 10 ，並且當鍵盤出現時其中的textfield必須向上滾動 100 才能可見，那么該文本字段將超出表的范圍。

Answer 17

聲明一個委托，將您的文本字段分配給該委托，然后包含這些方法。

假設您有一個帶有電子郵件和密碼文本字段的登錄表單，此代碼將非常適合：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    [self.emailTextField resignFirstResponder];
    [self.passwordTextField resignFirstResponder];

}

- (BOOL)textFieldShouldReturn:(UITextField *)textField {

    if (self.emailTextField == textField) {
        [self.passwordTextField becomeFirstResponder];
    } else {
        [self.emailTextField resignFirstResponder];
        [self.passwordTextField resignFirstResponder];
    }
    return NO;
}
- (void)viewWillAppear:(BOOL)animated {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}

- (void)viewWillDisappear:(BOOL)animated {
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}

        CGRect f = self.view.frame;
        f.origin.y = -0.5f * keyboardSize.height;
        self.view.frame = f;
    }];
}

-(void)keyboardWillHide:(NSNotification *)notification

我剛剛創建了一個輕量級的鍵盤處理程序來跟隨鍵盤框架。

用法：

 self.keyboardHandler = [EDKeyboardHandler new];

  [self.keyboardHandler listenWithBlock:^(KeyboardInfo *model)
  {
    //adjust view positions according to keyboard position here
  }];

並且 KeyboardInfo 模型具有以下屬性：

typedef enum : NSUInteger {
    KeyboardStatusDidShow,
    KeyboardStatusWillShow,
    KeyboardStatusDidHide,
    KeyboardStatusWillHide,
} KeyboardStatus;

@interface KeyboardInfo:NSObject

@property (nonatomic,readonly) NSTimeInterval animationDuration;
@property (nonatomic,readonly) CGRect keyboardFrame;
@property (nonatomic,readonly) NSInteger animationCurve;
@property (nonatomic,readonly) KeyboardStatus status;

@end
