ios - 当 View 已向上移动键盘时，UINavigationBar BarButtonItems 不响应点击

Question

我在显示键盘时将模态视图向上移动，以防止界面的某些部分被键盘隐藏。

当 View 已移动时，工具栏取消/保存按钮不会响应点击。检测到模态内的点击并响应良好。

我已经将其设置为当在文本字段外点击时键盘应该消失，但是当点击导航栏时这也不起作用。

当 View 被偏移时，我如何适本地响应对 barbuttonitems 的点击？

这是我在显示键盘时向上移动模式的方法:

- (void) animateTextField: (UITextField*) textField up: (BOOL) up
{
    int movementDistance;
    float movementDuration;

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {

        if(
           UIInterfaceOrientationIsLandscape(self.interfaceOrientation)
          )
        { 
            //code for landscape shift - not relevant because you can't see the toolbar
       else{
            NSLog(@"Portrait for animation");
            movementDistance = IPAD_PORTRAIT_KEYBOARD_HEIGHT; 
            movementDuration = KEYBOARD_ANIMATION_DURATION; 

            if(up){
                keyboardAppearedInLandscape = false;   
            }else{
                //the keyboard is going down
                NSLog(@"Keyboard going down");
                //is the iPad in the same orientation now that it was when it came up?
                if ([[UIDevice currentDevice] orientation] == UIInterfaceOrientationPortrait || [[UIDevice currentDevice] orientation] == UIInterfaceOrientationPortraitUpsideDown) 
                {
                    if (!keyboardAppearedInLandscape) {
                        //don't do anything - the keyboard is being dismissed in the same way it was called. It's much the same in any case.
                    }else{
                        movementDistance = IPAD_LANDSCAPE_KEYBOARD_HEIGHT;
                    }
                }
            }
        }

    } 
    int movement = (up ? -movementDistance : movementDistance);

    [UIView beginAnimations: @"anim" context: nil];
    [UIView setAnimationBeginsFromCurrentState: YES];
    [UIView setAnimationDuration: movementDuration];
    self.view.frame = CGRectOffset(self.view.frame, 0, movement);
    [UIView commitAnimations];
}
//end text field movy-ness

下面是我如何检测文本字段外的点击以关闭键盘:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {      
        //keyboard goes away if you tap somewhere else on screen
        NSLog(@"resignFirstResponder");
        [self.view endEditing:YES];

    }

    [super touchesBegan:touches withEvent:event];

}

您不会收到原始矩形边界之外的触摸事件，因为...

• SuperView 认为 View 没有改变位置
• View 在自身内部向上移动，而不是从外部移动
• 屏幕上的视觉元素正在变化但未被识别

相反，正确移动 subview :

1. SuperView 应该响应 UIKeyboard
   • 利用UIKeyboardWillHideNotification && UIKeyboardWillShowNotification
2. 将 ClipsToBounds 设置为 YES
   • 现在您将看不到 View 边界之外的内容。
   • 使调试更有效
