iOS获取键盘高度

iOS获取键盘高度

（1）注册监听，监听键盘的弹出

[[NSNotificationCenter defaultCenter] addObserver:self

selector:@selector(handleKeyBoardNotification:)

name:UIKeyboardWillShowNotification

object:nil];

（2）在监听的触发方法当中，使用如下代码获取键盘高度

-(void)handleKeyBoardNotification:(NSNotification *)sender {

// 获取键盘高度，关键的一句

NSValue *value = [sender.userInfo objectForKey:@"UIKeyboardBoundsUserInfoKey"];

CGSize keyboardSize = [value CGRectValue].size;

float keyboardHeight = keyboardSize.height;

}
