如何識別特定視圖中的觸摸

Question

如何觸摸特定視圖。

我使用

CGPoint Location = [[touches anyObject] locationInView:self.view ]; 

但要觸發只有在點擊的特定子視圖的操作。
如何做到這一點。

Answer 1

我得到了自己的答案......但由於其他這讓我對這個

這裏是

UITouch *touch ; 
touch = [[event allTouches] anyObject]; 


    if ([touch view] == necessarySubView) 
{ 
//Do what ever you want 
} 

Answer 2

你應該創建一個子類（或創建一個類別）的UIView和覆蓋

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

其中重定向消息到相應的委託。

Answer 3

難道ü嘗試

CGPoint Location = [[touches anyObject] locationInView:necessarySubView ]; 

Answer 4

試試這個

//here enable the touch 
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { 
    // get touch event 
    UITouch *touch = [[event allTouches] anyObject]; 
    CGPoint touchLocation = [touch locationInView:self.view]; 

    if (CGRectContainsPoint(yoursubview_Name.frame, touchLocation)) { 
     //Your logic 
     NSLog(@" touched"); 
    } 
} 

Answer 5

// here Tiles is a separate class inherited from UIView Class 
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { 
    UITouch *touch = [touches anyObject]; 
    if ([[touch view] isKindOfClass:[Tiles class]]) { 
     NSLog(@"[touch view].tag = %d", [touch view].tag); 
    } 
} 

這樣你可以找到視圖或子視圖觸摸

繼承人swift3版本，而多點觸控：

override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) { 
    if let touch = touches.first, self.bounds.contains(touch.location(in: self)) { 
     // Your code 
    } 
}
