键盘改变了高度

Question

！[在此处输入图像说明] [1] 当我尝试添加窗口作为其中包含视图的子视图时，键盘在屏幕底部稍微离开。怎么解决？这是我的代码。

keyboardWindowFrame = nil;
keyboardWindowFrame = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
for(UIView* potentialKeyboard in keyboardWindowFrame.subviews)
{   // if the real keyboard-view is found, remember it.
    if([[potentialKeyboard description] hasPrefix:@"<UIPeripheralHost"] == YES)
    {
        NSLog(@"Keyboard Frame: %@",NSStringFromCGRect(potentialKeyboard.frame));
        keyboard = potentialKeyboard;
        [keyboard addSubview:viewForGlobeEmoji];
        [self.view addSubview:keyboard];
    }
}

以下是附加屏幕截图：

现在添加

后工具栏和键盘之间有空格

  if([[potentialKeyboard description] hasPrefix:@"<UIPeripheralHost"] == YES)
        {
            NSLog(@"potentialKeyboard: %@",NSStringFromCGRect(potentialKeyboard.frame));


            keyboard = potentialKeyboard;
            CGRect frame = keyboard.frame;
            frame.origin.y = 332;
            keyboard.frame = frame;
            [keyboard addSubview:viewForGlobeEmoji];
            [self.view addSubview:keyboard];

         }

Answer 1

你应该在这一行下方设置键盘框架：

keyboard = potentialKeyboard;
CGRect frame = keyboard.frame;
frame.origin.y = xxx;
keyboard.frame = frame

Answer 2

做这样的事情是完全错误的，并且不会受到appstore评论员的欢迎。您正在篡改未记录的系统API，这只是意外行为的结果。

如何做到你想要的标准方法：

1. 检查键盘大小和位置的键盘通知。
2. [UIResponder inputView]
