问题描述
所以我有一个加载UIWebView的视图,我希望覆盖用户可以点击进入另一个视图的UIButton。
So I have a view that loads a UIWebView and I want to overlay UIButton the user can tap on to go to another view.
我设法将按钮放在网页视图上,但我似乎无法点击它。
I managed to place the button over the web view but I can't seem to be able to tap on it.
这是我的代码:
class ButtonView: UIView {
var button: UIButton!
override init(frame: CGRect) {
super.init(frame: frame)
button = UIButton(frame: CGRectMake(0, 0, 50, 50))
button.layer.zPosition = 10
self.addSubview(button)
}
required init(coder aDecoder: NSCoder) {
fatalError("Init(coder:) has not been implemented")
}
}
class MyViewController : UIViewController, UIWebViewDelegate {
var buttonView = ButtonView()
@IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
self.loadWebView() //This just loads a url to the web view...
webView.layer.zPosition = 1
buttonView = ButtonView(frame: CGRectMake(0, 0, 100, 100))
buttonView.layer.zPosition = 100
buttonView.button.addTarget(self, action: "buttonEvent:", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(buttonView)
}
func buttonEvent(sender: AnyObject!){
println("Tap detected!")
}
}
因此,这会按预期显示网页视图顶部的按钮,但我无法点击它。
So this displays the button on top of the web view as expected but I can't tap on it.
虽然如果我隐藏网页视图,我可以点按在按钮上没有任何问题
Although if I hide the web view I can tap on the button without any problems
这是一个zPosition问题吗?或其他什么?
Is this a zPosition problem? or something else?
推荐答案
只要您更换它就可以正常工作:
It could work as it is as long as you replace:
self.view.addSubview(buttonView)
使用:
webView.addSubview(buttonView)
所以基本上将包含按钮的视图添加到Web视图中
So basically add the view containing the button to the web view instead
