iOS关闭键盘的两种简单方法

方法一：

//1, 关闭键盘

[[[UIApplication sharedApplication] keyWindow] endEditing:YES];

想必大家都遇到过一个view上好多输入框，为了关闭弹出的软键盘要遍历然后调用resignFirstResponder的吧？今天竟然发现一个关键这个view上可能 打开的键盘很简单:[self.view endEditing:YES];

直接ok了。

方法二：

//2, 关闭键盘

[[self findFirstResponderBeneathView:self] resignFirstResponder];

[[self findFirstResponderBeneathView:self]
becomeFirstResponder];//打开键盘

- (UIView*)findFirstResponderBeneathView:(UIView*)view

{

// Search recursively for first responder

for ( UIView *childView in view.subviews ) {

if ( [childView respondsToSelector:@selector(isFirstResponder)] && [childView isFirstResponder] )

return childView;

UIView *result = [self findFirstResponderBeneathView:childView];

if ( result )

return result;

}

return nil;

}
