《隐藏键盘》《隐藏PickerView控键》如果是xib中 点击空白处隐藏键盘

一、隐藏键盘。

1、首先设置xib中得UIView的Custom class为UIControl

2、设置关系事件，将xib中得UIView拖到.h区中

connection设为action；ID类型点击事件为Touch Up Inside

3、在.m编写隐藏代码：

- (IBAction)按钮名称:(id)sender {  

     [self.view endEditing:YES];  

}

 

备注：如果通过view创建的可以直接 [self.view endEditing:YES];

 

二、隐藏PickerView控件。

- (void)viewDidLoad

{

    [super viewDidLoad];

//----------------------------------(

   UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(keyboardHide:)];

   //设置成NO表示当前控件响应后会传播到其他控件上，默认为YES。

   tapGestureRecognizer.cancelsTouchesInView = NO;

   [self.view addGestureRecognizer:tapGestureRecognizer];

//-这个方法也可以用于是点击空白处移除键盘或pickerview控件------------------------------)

}

-(void)keyboardHide:(UITapGestureRecognizer *)tap{

CATransition *animation = [CATransition  animation];

        animation.delegate = self;

        animation.duration = 0.3;

        animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

        animation.type = kCATransitionPush;

        animation.subtype = kCATransitionFromBottom;

        [locateView setAlpha:0.0f];

        [locateView.layer addAnimation:animation forKey:@"TSLocateView"];

        [locateView performSelector:@selector(removeFromSuperview) withObject:nil afterDelay:0.3];　　

        self.Nolocation.userInteractionEnabled =YES;

}
