问题描述
当 UIImageView
被触摸时,您将如何检测并运行操作?这是我到目前为止的代码:
How would you detect and run an action when a UIImageView
is touched?
This is the code that I have so far:
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
var touch: UITouch = UITouch()
if touch.view == profileImage {
println("image touched")
}
}
推荐答案
您可以使用 Interface Builder 或在代码中(根据需要)将 UITapGestureRecognizer
放入您的 UIImageView
,我更喜欢第一个.然后你可以放一个 @IBAction
并在你的 UIImageView
中处理点击,不要忘记将 UserInteractionEnabled
设置为 true
在 Interface Builder 或代码中.
You can put an UITapGestureRecognizer
inside your UIImageView
using Interface Builder or in code (as you want), I prefer the first. Then you can put an @IBAction
and handle the tap inside your UIImageView
, Don't forget to set the UserInteractionEnabled
to true
in Interface Builder or in code.
@IBAction func imageTapped(sender: AnyObject) {
println("Image Tapped.")
}
希望对你有所帮助.
