iphone - 键盘隐藏时的iOS事件

Question

我需要控制，在显示键盘并按下完成按钮后，何时隐藏键盘。在 iOS 上隐藏键盘时会触发哪个事件？谢谢

Answer 1

是的，使用下面的

//UIKeyboardDidHideNotification when keyboard is fully hidden
//name:UIKeyboardWillHideNotification when keyboard is going to be hidden

[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(onKeyboardHide:) name:UIKeyboardWillHideNotification object:nil];

还有 onKeyboardHide

-(void)onKeyboardHide:(NSNotification *)notification
{
     //keyboard will hide
}
