防止同时触摸多个按钮

In iOS is there anyway to prevent a UIView containing multiple buttons (siblings) from being simultaneously from being touched? For instance, two non-overlapping buttons that are side by side can be tapped at the same time with two touches.

在iOS中，无论如何都要防止同时触摸包含多个按钮（同级）的UIView？例如，可以在两次触摸的同时轻敲两个并排的非重叠按钮。

for(UIView* v in self.view.subviews)
    {

You need to find all buttons on that view and set the "exclusiveTouch" property to true in order to prevent multi touch at the same time.

您需要找到该视图上的所有按钮并将“exclusiveTouch”属性设置为true，以便同时防止多点触摸。

func exclusiveTouchForButtons(view: UIView) {
    for cmp in view.subviews {
        if let cmpButton = cmp as? UIButton {
            cmpButton.exclusiveTouch = true
        } else {
            exclusiveTouchForButtons(cmp)
        }
    }
}
