手势触碰点击

有时候下面方法无效：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{

[self.view endEditing:YES];

}

只好手动添加手势触碰点击：

@property (strong) UITapGestureRecognizer *sideslipTapGes;

@property (nonatomic, strong) UIView *touchView;

//单击覆盖层手势

_sideslipTapGes= [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handeTap)];

[_sideslipTapGes setNumberOfTapsRequired:1];

[_touchView addGestureRecognizer:_sideslipTapGes];

- (void)handeTap {

[self.view endEditing:YES];

}
