给uiview或者其他控件添加点击手势或者其他手势

前言：有的时候我们需要点击iamge或者label 让某个控件实现点击事件

注意：这里特别提醒一下，大部分控件如果没有响应方法，那么一般是没有开启控件的用户交互，在本文的代码的label的懒加载里有注释，注意看一下，假如是uiimage 也是要开启才可以使用哦！

第一步：遵守协议

第二步：创建控件，并且懒加载控件

/** view */

@property(nonatomic,strong)UIView *myView;

/** label */

@property(nonatomic,strong)UILabel *myLabel;

-(UIView *)myView{

if (_myView == nil) {

_myView = [[UIView alloc]init];

_myView.frame = CGRectMake(100, 100, 100, 100);

_myView.backgroundColor = [UIColor orangeColor];

[self.view addSubview:_myView];

}

return _myView;

}

-(UILabel *)myLabel{

if (_myLabel == nil) {

_myLabel = [[UILabel alloc]init];

_myLabel.frame = CGRectMake(100, 200, 120, 30);

_myLabel.text = @"添加点击手势";

_myLabel.userInteractionEnabled = YES;//开启用户交互

[self.view addSubview:_myLabel];

}

return _myLabel;}

第三步：在当前控制器创建对象，设置方法，设置代理等等

//这个可以加到任何控件上,比如你只想响应WebView，我正好填满整个屏幕

UITapGestureRecognizer* singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];

[self.myView addGestureRecognizer:singleTap];

singleTap.delegate = self;

singleTap.cancelsTouchesInView = NO;

//这个可以加到任何控件上,比如你只想响应WebView，我正好填满整个屏幕

UITapGestureRecognizer* singleTapLabel = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTapLabel:)];

[self.myLabel addGestureRecognizer:singleTapLabel];

singleTapLabel.delegate = self;

singleTapLabel.cancelsTouchesInView = NO;

第四步：实现代理方法和设置的响应方法

/** 代理方法 */

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{

return YES;

}

/** view的点击响应方法 */

-(void)handleSingleTap:(UITapGestureRecognizer *)sender{

CGPoint point = [sender locationInView:self.view];

NSLog(@"view  pointx:%f,y:%f",point.x,point.y);

}

/** Lable的点击响应方法 */

-(void)handleSingleTapLabel:(UITapGestureRecognizer *)sender{

CGPoint point = [sender locationInView:self.view];

NSLog(@"label pointx:%f,y:%f",point.x,point.y);

}

/** 懒加载 */

-(UIView *)myView{

if (_myView == nil) {

_myView = [[UIView alloc]init];

_myView.frame = CGRectMake(100, 100, 100, 100);

_myView.backgroundColor = [UIColor orangeColor];

[self.view addSubview:_myView];

}

return _myView;

}

-(UILabel *)myLabel{

if (_myLabel == nil) {

_myLabel = [[UILabel alloc]init];

_myLabel.frame = CGRectMake(100, 200, 120, 30);

_myLabel.text = @"添加点击手势";

_myLabel.userInteractionEnabled = YES;//开启用户交互

[self.view addSubview:_myLabel];

}

return _myLabel;

}
