在UIView中添加点击事件oc及swift

UIView继承于UIResponder是没有addTarget 方法的，所有只能在UIView上添加手势UITapGestureRecognizer来实现点击事件。

首先设定UIView（或其子类）为可交互的：

oc：

iconView.userInteractionEnabled = YES;

添加tap手势：

//tap手势

UITapGestureRecognizer *tapGesture=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapevent:)];

将手势添加至需要相应的view中

[iconView addGestureRecognizer:tapGesture];

默认为单击触发事件：

设置手指个数：

[tapGesture setNumberOfTapsRequired:1];

执行触发的方法：

- (void)tapevent:(UITapGestureRecognizer *)gesture {
NSLog(@"单击");
}

Swift:

view.isUserInteractionEnabled = true
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(tapGestureAction))
tapGesture.numberOfTapsRequired = 1
view.addGestureRecognizer(tapGesture)

//MARK: 点击事件
extension MeViewController{

@objc fileprivate func tapGestureAction(){
LGJLog("跳转个人中心")
}
}
