[英]How to change the status bar background color and text color on iOS 7?
我當前的應用程序在 iOS 5 和 6 上運行。
導航欄為橙色,狀態欄為黑色背景色和白色文本顏色。 但是,當我在 iOS 7 上運行相同的應用程序時,我觀察到狀態欄看起來透明,背景顏色與導航欄相同,並且狀態欄文本顏色為黑色。
因此,我無法區分狀態欄和導航欄。
如何使狀態欄看起來與 iOS 5 和 6 中的一樣,即黑色背景顏色和白色文本顏色? 如何以編程方式執行此操作?
警告:它不再適用於 iOS 13 和 Xcode 11。
================================================== ======================
我不得不嘗試尋找其他方法。 這不涉及窗口上的addSubview
。 因為當鍵盤出現時我正在向上移動窗口。
- (void)setStatusBarBackgroundColor:(UIColor *)color {
UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"];
if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) {
statusBar.backgroundColor = color;
}
}
func setStatusBarBackgroundColor(color: UIColor) {
guard let statusBar = UIApplication.sharedApplication().valueForKey("statusBarWindow")?.valueForKey("statusBar") as? UIView else {
return
}
statusBar.backgroundColor = color
}
func setStatusBarBackgroundColor(color: UIColor) {
guard let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView else { return }
statusBar.backgroundColor = color
}
調用此表單application:didFinishLaunchingWithOptions
對我application:didFinishLaunchingWithOptions
。
注意我們在應用商店中有一個具有這種邏輯的應用。 所以我想應用商店政策沒問題。
編輯:
使用風險自負。 形成評論者@Sebyddd
我有一個應用程序被拒絕的原因,而另一個被接受了。 他們確實認為這是私有 API 使用,因此您在審查過程中很幸運:) – Sebyddd
轉到您的應用程序info.plist
1) 將View controller-based status bar appearance
為NO
2) 設置Status bar style
為UIStatusBarStyleLightContent
然后轉到您的應用程序委托並將以下代碼粘貼到您設置 Windows 的 RootViewController 的位置。
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0,[UIScreen mainScreen].bounds.size.width, 20)];
view.backgroundColor=[UIColor blackColor];
[self.window.rootViewController.view addSubview:view];
}
希望它有幫助。
1) 在 plist 中將 UIViewControllerBasedStatusBarAppearance 設置為 YES
2)在viewDidLoad中做一個[self setNeedsStatusBarAppearanceUpdate];
3)添加如下方法:
-(UIStatusBarStyle)preferredStatusBarStyle{
return UIStatusBarStyleLightContent;
}
更新:
還要檢查開發人員指南到 ios-7 狀態欄
iOS 7中處理狀態欄背景色時,有兩種情況
案例 1:使用導航欄查看
在這種情況下,在您的 viewDidLoad 方法中使用以下代碼
UIApplication *app = [UIApplication sharedApplication];
CGFloat statusBarHeight = app.statusBarFrame.size.height;
UIView *statusBarView = [[UIView alloc] initWithFrame:CGRectMake(0, -statusBarHeight, [UIScreen mainScreen].bounds.size.width, statusBarHeight)];
statusBarView.backgroundColor = [UIColor yellowColor];
[self.navigationController.navigationBar addSubview:statusBarView];
案例 2:沒有導航欄的視圖
在這種情況下,在您的 viewDidLoad 方法中使用以下代碼
UIApplication *app = [UIApplication sharedApplication];
CGFloat statusBarHeight = app.statusBarFrame.size.height;
UIView *statusBarView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, statusBarHeight)];
statusBarView.backgroundColor = [UIColor yellowColor];
[self.view addSubview:statusBarView];
源碼鏈接http://code-ios.blogspot.in/2014/08/how-to-change-background-color-of.html
您可以在應用程序啟動期間或視圖控制器的 viewDidLoad 期間設置狀態欄的背景顏色。
extension UIApplication {
var statusBarView: UIView? {
return value(forKey: "statusBar") as? UIView
}
}
// Set upon application launch, if you've application based status bar
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
return true
}
}
or
// Set it from your view controller if you've view controller based statusbar
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
}
}
這是結果:
這是有關狀態欄更改的Apple 指南/說明。 狀態欄中只允許深色和淺色(同時和黑色)。
這是 - 如何更改狀態欄樣式:
如果要設置狀態欄樣式、應用程序級別,請在“.plist”文件中將UIViewControllerBasedStatusBarAppearance
設置為NO
。
如果您想設置狀態欄樣式,請在視圖控制器級別執行以下步驟:
.plist
文件中將UIViewControllerBasedStatusBarAppearance
設置為YES
。 在viewDidLoad中添加函數setNeedsStatusBarAppearanceUpdate
覆蓋視圖控制器中的 preferredStatusBarStyle。
——
override func viewDidLoad() {
super.viewDidLoad()
self.setNeedsStatusBarAppearanceUpdate()
}
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
在 iOS 7 中狀態欄沒有背景,因此如果你在它后面放一個 20 像素高的黑色視圖,你將獲得與 iOS 6 相同的結果。
此外,您可能需要閱讀iOS 7 UI Transition Guide以獲取有關該主題的更多信息。
在你的 ViewDidLoad 方法中寫下這個:
if ([self respondsToSelector:@selector(setEdgesForExtendedLayout:)]) {
self.edgesForExtendedLayout=UIRectEdgeNone;
self.extendedLayoutIncludesOpaqueBars=NO;
self.automaticallyAdjustsScrollViewInsets=NO;
}
它也在一定程度上修復了我的狀態欄顏色和其他 UI 錯位。
這是一個完整的復制和粘貼解決方案,帶有
涉及的每個問題。
關於 keyPath statusBarWindow.statusBar
的驚人發現。 不錯的。
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// handle the iOS bar!
// >>>>>NOTE<<<<<
// >>>>>NOTE<<<<<
// >>>>>NOTE<<<<<
// "Status Bar Style" refers to the >>>>>color of the TEXT<<<<<< of the Apple status bar,
// it does NOT refer to the background color of the bar. This causes a lot of confusion.
// >>>>>NOTE<<<<<
// >>>>>NOTE<<<<<
// >>>>>NOTE<<<<<
// our app is white, so we want the Apple bar to be white (with, obviously, black writing)
// make the ultimate window of OUR app actually start only BELOW Apple's bar....
// so, in storyboard, never think about the issue. design to the full height in storyboard.
let h = UIApplication.shared.statusBarFrame.size.height
let f = self.window?.frame
self.window?.frame = CGRect(x: 0, y: h, width: f!.size.width, height: f!.size.height - h)
// next, in your plist be sure to have this: you almost always want this anyway:
// <key>UIViewControllerBasedStatusBarAppearance</key>
// <false/>
// next - very simply in the app Target, select "Status Bar Style" to Default.
// Do nothing in the plist regarding "Status Bar Style" - in modern Xcode, setting
// the "Status Bar Style" toggle simply sets the plist for you.
// finally, method A:
// set the bg of the Apple bar to white. Technique courtesy Warif Akhand Rishi.
// note: self.window?.clipsToBounds = true-or-false, makes no difference in method A.
if let sb = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView {
sb.backgroundColor = UIColor.white
// if you prefer a light gray under there...
//sb.backgroundColor = UIColor(hue: 0, saturation: 0, brightness: 0.9, alpha: 1)
}
/*
// if you prefer or if necessary, method B:
// explicitly actually add a background, in our app, to sit behind the apple bar....
self.window?.clipsToBounds = false // MUST be false if you use this approach
let whiteness = UIView()
whiteness.frame = CGRect(x: 0, y: -h, width: f!.size.width, height: h)
whiteness.backgroundColor = UIColor.green
self.window!.addSubview(whiteness)
*/
return true
}
對於背景,您可以輕松添加視圖,例如:
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0,320, 20)];
view.backgroundColor = [UIColor colorWithRed:0/255.0 green:0/255.0 blue:0/255.0 alpha:0.1];
[navbar addSubview:view];
其中“導航欄”是一個 UINavigationBar。
只是為了添加 Shahid 的答案 - 您可以使用此(iOS7+)來考慮方向變化或不同的設備:
- (BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
//Create the background
UIView* statusBg = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.window.frame.size.width, 20)];
statusBg.backgroundColor = [UIColor colorWithWhite:1 alpha:.7];
//Add the view behind the status bar
[self.window.rootViewController.view addSubview:statusBg];
//set the constraints to auto-resize
statusBg.translatesAutoresizingMaskIntoConstraints = NO;
[statusBg.superview addConstraint:[NSLayoutConstraint constraintWithItem:statusBg attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:statusBg.superview attribute:NSLayoutAttributeTop multiplier:1.0 constant:0.0]];
[statusBg.superview addConstraint:[NSLayoutConstraint constraintWithItem:statusBg attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationEqual toItem:statusBg.superview attribute:NSLayoutAttributeLeft multiplier:1.0 constant:0.0]];
[statusBg.superview addConstraint:[NSLayoutConstraint constraintWithItem:statusBg attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual toItem:statusBg.superview attribute:NSLayoutAttributeRight multiplier:1.0 constant:0.0]];
[statusBg.superview addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[statusBg(==20)]" options:0 metrics:nil views:NSDictionaryOfVariableBindings(statusBg)]];
[statusBg.superview setNeedsUpdateConstraints];
...
}
斯威夫特 4:
// 改變狀態欄背景顏色
let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
statusBar?.backgroundColor = UIColor.red
更改狀態欄的背景顏色:Swift:
let proxyViewForStatusBar : UIView = UIView(frame: CGRectMake(0, 0,self.view.frame.size.width, 20))
proxyViewForStatusBar.backgroundColor=UIColor.whiteColor()
self.view.addSubview(proxyViewForStatusBar)
對於 iOS 9 上的 swift 2.0
將以下內容放在應用程序委托中的 didFinishLaunchingWithOptions 下:
let view: UIView = UIView.init(frame: CGRectMake(0, 0, UIScreen.mainScreen().bounds.size.width, 20))
view.backgroundColor = UIColor.blackColor() //The colour you want to set
view.alpha = 0.1 //This and the line above is set like this just if you want
the status bar a darker shade of
the colour you already have behind it.
self.window!.rootViewController!.view.addSubview(view)
iTroid23 解決方案對我有用。 我錯過了 Swift 解決方案。 所以也許這有幫助:
1) 在我的 plist 中,我必須添加:
<key>UIViewControllerBasedStatusBarAppearance</key>
<true/>
2)我不需要調用“setNeedsStatusBarAppearanceUpdate”。
3)在swift中,我必須將其添加到我的 UIViewController 中:
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return UIStatusBarStyle.LightContent
}
如果你使用UINavigationController
,你可以使用這樣的擴展:
extension UINavigationController {
private struct AssociatedKeys {
static var navigationBarBackgroundViewName = "NavigationBarBackground"
}
var navigationBarBackgroundView: UIView? {
get {
return objc_getAssociatedObject(self,
&AssociatedKeys.navigationBarBackgroundViewName) as? UIView
}
set(newValue) {
objc_setAssociatedObject(self,
&AssociatedKeys.navigationBarBackgroundViewName,
newValue,
.OBJC_ASSOCIATION_RETAIN)
}
}
func setNavigationBar(hidden isHidden: Bool, animated: Bool = false) {
if animated {
UIView.animate(withDuration: 0.3) {
self.navigationBarBackgroundView?.isHidden = isHidden
}
} else {
navigationBarBackgroundView?.isHidden = isHidden
}
}
func setNavigationBarBackground(color: UIColor, includingStatusBar: Bool = true, animated: Bool = false) {
navigationBarBackgroundView?.backgroundColor = UIColor.clear
navigationBar.backgroundColor = UIColor.clear
navigationBar.barTintColor = UIColor.clear
let setupOperation = {
if includingStatusBar {
self.navigationBarBackgroundView?.isHidden = false
if self.navigationBarBackgroundView == nil {
self.setupBackgroundView()
}
self.navigationBarBackgroundView?.backgroundColor = color
} else {
self.navigationBarBackgroundView?.isHidden = true
self.navigationBar.backgroundColor = color
}
}
if animated {
UIView.animate(withDuration: 0.3) {
setupOperation()
}
} else {
setupOperation()
}
}
private func setupBackgroundView() {
var frame = navigationBar.frame
frame.origin.y = 0
frame.size.height = 64
navigationBarBackgroundView = UIView(frame: frame)
navigationBarBackgroundView?.translatesAutoresizingMaskIntoConstraints = true
navigationBarBackgroundView?.autoresizingMask = [.flexibleWidth, .flexibleBottomMargin]
navigationBarBackgroundView?.isUserInteractionEnabled = false
view.insertSubview(navigationBarBackgroundView!, aboveSubview: navigationBar)
}
}
它基本上使導航欄背景透明,並使用另一個 UIView 作為背景。 您可以調用導航控制器的setNavigationBarBackground
方法來設置導航欄背景顏色和狀態欄。
請記住,當您想隱藏導航欄時,您必須在擴展中使用setNavigationBar(hidden: Bool, animated: Bool)
方法,否則用作背景的視圖仍然可見。
試試這個。 在您的 appdelegate 類didFinishLaunchingWithOptions
函數中使用此代碼:
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
[application setStatusBarHidden:NO];
UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"];
if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) {
statusBar.backgroundColor = [UIColor blackColor];
}
斯威夫特 4
在Info.plist
添加這個屬性
查看基於控制器的狀態欄外觀為 NO
然后在AppDelegate
的didFinishLaunchingWithOptions
添加這些代碼行
UIApplication.shared.isStatusBarHidden = false
UIApplication.shared.statusBarStyle = .lightContent
下面的代碼片段應該適用於 Objective C。
if (@available(iOS 13.0, *)) {
UIView *statusBar = [[UIView alloc]initWithFrame:[UIApplication sharedApplication].keyWindow.windowScene.statusBarManager.statusBarFrame] ;
statusBar.backgroundColor = [UIColor whiteColor];
[[UIApplication sharedApplication].keyWindow addSubview:statusBar];
} else {
// Fallback on earlier versions
UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"];
if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) {
statusBar.backgroundColor = [UIColor whiteColor];//set whatever color you like
}
}
對於條形顏色:您為條形提供自定義背景圖像。
對於文本顏色:使用關於 iOS 中的文本處理中的信息
我成功地在AppDelegate.cs
文件中添加了非常簡單的方法自定義 StatusBar 顏色:
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
下一個代碼:
UIView statusBar = UIApplication.SharedApplication.ValueForKey(new NSString("statusBar")) as UIView;
if (statusBar!=null && statusBar.RespondsToSelector(new Selector("setBackgroundColor:")))
{
statusBar.BackgroundColor = Color.FromHex(RedColorHex).ToUIColor();
}
所以你會得到這樣的東西:
鏈接: https : //jorgearamirez.wordpress.com/2016/07/18/lesson-x-effects-for-the-status-bar/
在 Swift 5 和 Xcode 10.2 中
DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + Double(Int64(0.1 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC), execute: {
//Set status bar background colour
let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
statusBar?.backgroundColor = UIColor.red
//Set navigation bar subView background colour
for view in controller.navigationController?.navigationBar.subviews ?? [] {
view.tintColor = UIColor.white
view.backgroundColor = UIColor.red
}
})
在這里我修復了狀態欄背景顏色和導航欄背景顏色。 如果你不想導航欄顏色評論它。
斯威夫特代碼
let statusBarView = UIView(frame: CGRect(x: 0, y: 0, width: view.width, height: 20.0))
statusBarView.backgroundColor = UIColor.red
self.navigationController?.view.addSubview(statusBarView)
您可以像下面這樣使用,適用於 iOS 13* 和 Swift 4。
1 -> 將基於視圖控制器的狀態欄外觀設置為 NO
extension UIApplication {
var statusBarView: UIView? {
if #available(iOS 13.0, *) {
let statusBar = UIView()
statusBar.frame = UIApplication.shared.statusBarFrame
UIApplication.shared.keyWindow?.addSubview(statusBar)
return statusBar
} else {
let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
return statusBar
}
}
在 didFinishLaunchingWithOptions 中使用
UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
使用此擴展
extension UINavigationController {
func setStatusBar(backgroundColor: UIColor) {
let statusBarFrame: CGRect
if #available(iOS 13.0, *) {
statusBarFrame = view.window?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero
} else {
statusBarFrame = UIApplication.shared.statusBarFrame
}
let statusBarView = UIView(frame: statusBarFrame)
statusBarView.backgroundColor = backgroundColor
view.addSubview(statusBarView)
}
}
