iphone - How do I make a section of my UIView a clickable area

Question

I want to make a certain section of my UIView clickable. When clicked, it triggers an IBAction, as would an UIButton.

How do I do this?

Answer 1

在您的视图上添加自定义 UIButton，您需要点击的任何位置，然后对其执行操作。

    UIButton *button = [UIButton buttonWithType:0];
    [button setFrame:CGRectmake(0,0,0,0)]; //What ever clickable area, provide here
    [button addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];

Answer 2

使用 UITapGestureRecognizer 并将透明按钮放在您希望可点击部分可用的区域上

Answer 3

添加UITapGestureRecognizer到您的UIView. 当您收到点击时，请检查您的识别器的locationInView:. 如果点击发生在您想要使点击敏感的区域，则触发操作；否则，忽略点击事件。
