自定義鍵盤，文本輸入到UITextField

Question

我在實現鍵盤附件時遇到困難，當在附件上按下鍵時，該鍵盤附件將文本輸入到UITextField中。 這是粗略的草案看起來像：

最終我想要當用戶點擊'@gmail按鈕，讓它輸入當前的電子郵件地址UITextField @ gmail.com，這樣用戶就不必輸入它了。 我遇到了問題，因為我正在以編程方式編寫keyboardaccessoryview，我無法弄清楚是否有來自keyboardaccess的keyinput轉到電子郵件地址的UITextField。 我曾經嘗試過使用IBAction

NSString *appendThisText = @"@gmail.com";
self.textFieldOne.text=[NSString stringWithFormat:@"%@%@", self.textFieldOne.text, appendThisText];

但那沒用。 我需要幫助。 這是我的signInViewController.h的代碼

#import <UIKit/UIKit.h>
#import <AVFoundation/AVAudioPlayer.h>
#import <AudioToolbox/AudioToolbox.h>

@interface signInViewController : UIViewController <UITextFieldDelegate, UITextViewDelegate> {
    AVAudioPlayer *sound;
    UIButton *myButton;
    UITextField *textFieldOne;
    UIButton *gmailButton;
    UIButton *meButton;
     UIButton *yahooButton;
    UIButton *outlookButton;
    UIView *inputAccView;
    UIButton *aolButton;
}


- (IBAction)playSwoosh:(id)sender;

- (IBAction)dismiss:(id)sender;

- (IBAction)toggleUIButtonImage:(id)sender;

- (IBAction)backgroundTouched:(id)sender;



@property (weak, nonatomic) IBOutlet UITextField *textFieldOne;
@property (weak, nonatomic) IBOutlet UITextField *textFieldTwo;
@property (nonatomic, retain) UIButton *gmailButton;
@property (nonatomic, retain) UIButton *meButton;
@property (nonatomic, retain) UIButton *yahooButton;
@property (nonatomic, retain) UIButton *outlookButton;
@property (nonatomic, retain) UIButton *aolButton;
@property (retain, nonatomic) UIButton *myButton;
@property (nonatomic, retain) UIView *inputAccView;

@end

這是我的signInViewController.m

#import "signInViewController.h"
#import <QuartzCore/QuartzCore.h>

@interface signInViewController ()

@end

@implementation signInViewController

@synthesize myButton = _myButton;
@synthesize textFieldOne = _textFieldOne;
@synthesize textFieldTwo = _textFieldTwo;
@synthesize inputAccView;
@synthesize gmailButton;
@synthesize yahooButton;
@synthesize meButton;

有人可以幫助我走這條路的正確道路。 我假設它將是一個從gmailButton到textFieldOne的IBAction作為插座，但我不確定如何以編程方式實現它。 它給了我一些問題。 我沒有問題將其轉換為UITextView但我不知道我是否需要使用UITextInput協議或什么。

基本上你只需要為你的按鈕添加一些目標動作（比如IBAction）。

只需將此添加到您的按鈕：

[yourButton addTarget:self action:@selector(yourButtonTapped) forControlEvents:UIControlEventTouchUpInside];

並創建一個處理水龍頭的方法，如：

- (void)yourButtonTapped
{
    self.textFieldOne.text = [self.textFieldOne.text stringByAppendingString:@"whatever"];
}
