帶有文本輸入到UITextField的自定義鍵盤

我在實現一個鍵盤附件時遇到了困難，該附件在按下附件上的按鍵時將文本輸入到UITextField中。這是看起來草稿，如：帶有文本輸入到UITextField的自定義鍵盤

最後我希望當在用戶點擊「@gmail按鈕，它在當前的電子郵件地址的UITextField @ gmail.com，所以用戶沒有按輸入」不得不輸入。我遇到了問題，因爲我正在以編程方式編寫keyboardaccessoryview，我無法弄清楚keyboardaccess的密鑰輸入是否到達電子郵件地址的UITextField。我曾嘗試做一個IBAction與

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

但這並沒有工作。我需要幫助。下面是我對signInViewController.h

#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

代碼，這裏是我的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;

是否有人可以幫助我得到這一個正確的道路上。我認爲這將是一個從gmailButton到textFieldOne作爲插座的IBAction，但我不確定如何以編程方式實現該插件。這給我一些問題。我沒有任何問題翻譯成UITextView，但我不知道是否需要使用UITextInput協議或什麼。

基本上你只需要添加一些目標動作給你的按鈕（如IBAction）。

只需添加到您的按鈕：

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

，並創建一個方法來處理自來水，如：

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

那太棒了！我不敢相信我忽略了這一點。我非常關注IBAction處理所有我完全錯過的事件。太棒了。謝謝！ – soulshined 2013-05-11 13:16:51

我會爲你投票，但我沒有足夠的聲望 – soulshined 2013-05-11 13:17:31

不客氣:-) – d4Rk 2013-05-11 16:47:41
