Ios 如何检测UIButton的触摸结束事件？

我想处理ui按钮触摸结束时发生的事件。我知道UIControl有一些实现触摸的事件（UIControlEventTouchDown、UIControlEventTouchCancel等）。但是除了UIControlEventTouchDown和UIControlEventTouchUpInside之外，我无法捕捉到它们中的任何一个

我的按钮是某个UIView的子视图。该UIView的userInteractionEnabled属性设置为YES

怎么了？

您可以根据

控制事件为按钮设置“行动目标”

- (void)addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents;

例如：

[yourButton addTarget:self 
           action:@selector(methodTouchDown:)
 forControlEvents:UIControlEventTouchDown];

[yourButton addTarget:self 
           action:@selector(methodTouchUpInside:)
 forControlEvents: UIControlEventTouchUpInside];

-(void)methodTouchDown:(id)sender{

   NSLog(@"TouchDown");
}
-(void)methodTouchUpInside:(id)sender{

  NSLog(@"TouchUpInside");
}

myButton.addTarget(self, action: #selector(MyViewController.touchDownEvent), for: .touchDown)
myButton.addTarget(self, action: #selector(MyViewController.touchUpEvent), for: [.touchUpInside, .touchUpOutside])

func touchDownEvent(_ sender: AnyObject) {
    print("TouchDown")
}

func touchUpEvent(_ sender: AnyObject) {
    print("TouchUp")
}

您需要创建自己的自定义类来扩展

UIButton

。 您的头文件应该如下所示

@interface customButton : UIButton
{
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;

---

然后制作您的实现文件

我认为这更容易

UILongPressGestureRecognizer *longPressOnButton = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressOnButton:)];
longPressOnButton.delegate = self;
btn.userInteractionEnabled = YES;
[btn addGestureRecognizer:longPressOnButton];



- (void)longPressOnButton:(UILongPressGestureRecognizer*)gesture
{
    // When you start touch the button
    if (gesture.state == UIGestureRecognizerStateBegan)
    {
       //start recording
    }
    // When you stop touch the button
    if (gesture.state == UIGestureRecognizerStateEnded)
    {
        //end recording
    }
}

---

只需为UIButton添加事件

触地：

和主要动作

触发：

- (IBAction)touchDown:(id)sender {
    NSLog(@"This will trigger when button is Touched");
}

- (IBAction)primaryActionTriggered:(id)sender {
    NSLog(@"This will trigger Only when touch end within Button Boundary (not Frame)");
}

@拉姆沙德在Swift 3.0语法中被接受 使用以下UIControl类的方法

例如：

[yourButton addTarget:self 
           action:@selector(methodTouchDown:)
 forControlEvents:UIControlEventTouchDown];

[yourButton addTarget:self 
           action:@selector(methodTouchUpInside:)
 forControlEvents: UIControlEventTouchUpInside];

-(void)methodTouchDown:(id)sender{

   NSLog(@"TouchDown");
}
-(void)methodTouchUpInside:(id)sender{

  NSLog(@"TouchUpInside");
}

myButton.addTarget(self, action: #selector(MyViewController.touchDownEvent), for: .touchDown)
myButton.addTarget(self, action: #selector(MyViewController.touchUpEvent), for: [.touchUpInside, .touchUpOutside])

func touchDownEvent(_ sender: AnyObject) {
    print("TouchDown")
}

func touchUpEvent(_ sender: AnyObject) {
    print("TouchUp")
}

---

Swift 3.0版本：

 let btn = UIButton(...)

 btn.addTarget(self, action: #selector(MyView.onTap(_:)), for: .touchUpInside)

 func onTap(_ sender: AnyObject) -> Void {

}

哦，效果很好。我的疏忽和我开了一个残酷的玩笑。谢谢，谢谢。这很有效。但如果用户在触摸时拖动，问题就会出现。TouchUpInside没有在那个tym期间被调用：（不幸的是，我的高级程序员禁止创建一个新类。但是这个解决方案也可以正常工作
