添加自定义按钮到数字键盘的键盘ios 6

我是新的IOS &我正在使用IOS 6。我的代码中有多个文本字段，其中一个使用数字键盘键盘，我想将自定义按钮添加到它。添加自定义按钮到数字键盘的键盘ios 6

我使用这个代码：

UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    doneButton.frame = CGRectMake(0, 163, 106, 53); 
    doneButton.adjustsImageWhenHighlighted = NO; 
    [doneButton setImage:[UIImage imageNamed:@"DoneUp.png"] forState:UIControlStateNormal]; 
    [doneButton setImage:[UIImage imageNamed:@"DoneDown.png"] forState:UIControlStateHighlighted]; 
    [doneButton addTarget:self action:@selector(doneButton:) forControlEvents:UIControlEventTouchUpInside]; 

    // locate keyboard view 
    UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1]; 
    UIView* keyboard; 
    for(int i=0; i<[tempWindow.subviews count]; i++) { 
     keyboard = [tempWindow.subviews objectAtIndex:i]; 
     // keyboard view found; add the custom button to it 
     if([[keyboard description] hasPrefix:@"<UIPeripheralHost"] == TRUE) 
      [keyboard addSubview:doneButton]; 
     }

选择是所谓的，但问题是，[[tempwindow.subviews]count]为0

谁能帮助我？

在此先感谢。

我会建议使用[InputAccessoryView（http://stackoverflow.com/a/11211721/593709） –

我已经使用下面的代码。核实。

- (void)textFieldDidBeginEditing:(UITextField *)textField { 
    if(textField==txt1) 
    { 

     [[NSNotificationCenter defaultCenter] addObserver: self 
               selector: @selector(keyboardDidShowOrHide:) 
                name: UIKeyboardDidShowNotification object:nil]; 

    } 
    else 
    { 

     [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidShowNotification object:nil]; 
    } 



} 
- (void) keyboardDidShowOrHide : (id) sender { 
    // create custom button 
    UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    doneButton.frame = CGRectMake(0, 427, 106, 53); 
    doneButton.adjustsImageWhenHighlighted = NO; 
    [doneButton setBackgroundImage:[UIImage imageNamed:@"doneup.png"] forState:UIControlStateNormal]; 
    [doneButton setBackgroundImage:[UIImage imageNamed:@"donedown.png"] forState:UIControlStateHighlighted]; 
    [doneButton addTarget:self action:@selector(doneButton:) forControlEvents:UIControlEventTouchUpInside]; 
    UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1]; 
    [tempWindow addSubview:doneButton]; 


} 
-(void)doneButton:(id)sender 
{ 
    UIButton *btntmp=sender; 
    [btntmp removeFromSuperview]; 
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidShowNotification object:nil]; 
    //[self setViewMovedUp:NO]; 
    [txt1 resignFirstResponder]; 
}

对于我来说，我使用下面的代码片段添加按钮，键盘：

- (void)addHideKeyboardButtonToKeyboard { 
    // Locate non-UIWindow. 
    UIWindow *keyboardWindow = nil; 
    for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) { 
     if (![[testWindow class] isEqual:[UIWindow class]]) { 
      keyboardWindow = testWindow; 
      break; 
     } 
    } 
    if (!keyboardWindow) return; 

    // Locate UIKeyboard. 
    UIView *foundKeyboard = nil; 
    for (__strong UIView *possibleKeyboard in [keyboardWindow subviews]) { 
     // iOS 4 sticks the UIKeyboard inside a UIPeripheralHostView. 
     if ([[possibleKeyboard description] hasPrefix:@"<UIPeripheralHostView"]) { 
      for (__strong UIView *anotherPossibleKeyboard in [possibleKeyboard subviews]) {  
       if ([[anotherPossibleKeyboard description] hasPrefix:@"<UIKeyboard"]) { 
        foundKeyboard = possibleKeyboard; 
        break; 
       } 
      } 
     } 
    } 

    if (foundKeyboard) { 
     [foundKeyboard addSubview:self.keyboardDoneButton];   
    } 
}

我用了你的代码，但它增加了按钮，然后它disappeard –

可以尝试建立完成按钮作为一个强大的财产，以便它将被保留？ –

是的，我作为一个强大的财产，我仍然有这个问题 –
