在iOS8中无法获得键盘高度的正确值 [英] can't get correct value of keyboard height in iOS8

问题描述

我使用这段代码来决定键盘的大小：

   - （void）keyboardWillChange：（NSNotification *）notification {
 NSDictionary * keyboardInfo = [notification userInfo]; 
 NSValue * keyboardFrameBegin = [keyboardInfo valueForKey：UIKeyboardFrameBeginUserInfoKey]; 
 CGRect keyboardFrameBeginRect = [keyboardFrameBegin CGRectValue]; 
 
} 
  

我在模拟器中运行。 >

问题是从iOS 8这将不会给出正确的值，如果键盘建议是向上或如果我推下他们得到不同的（不正确的）值。

如何获得键盘的确切大小，包括键盘建议？

解决方案

使用

  NSValue * keyboardFrameBegin = [keyboardInfo valueForKey：UIKeyboardFrameEndUserInfoKey]; 
  

I was using this code to determine what is the size of the keyboard :

- (void)keyboardWillChange:(NSNotification *)notification {
    NSDictionary* keyboardInfo = [notification userInfo];
    NSValue* keyboardFrameBegin = [keyboardInfo valueForKey:UIKeyboardFrameBeginUserInfoKey];
    CGRect keyboardFrameBeginRect = [keyboardFrameBegin CGRectValue];

}

I'm running this in the simulator.

The problem is since iOS 8 this will not give the correct value, if the keyboard suggestions is up or if I push them down I get different (not correct) values.

How can I get the exact size of the keyboard including the keyboard suggestions?

解决方案

Use

NSValue* keyboardFrameBegin = [keyboardInfo valueForKey:UIKeyboardFrameEndUserInfoKey];
