另一个问题来了。我有一个覆盖我的孔屏幕的视图。其中有一个用于显示 YouTube 视频的 webView 和一个用于关闭的按钮。该视图是通过 loadNibNamed() 加载的,无论我在做什么,我的 IBAction 都不会通过按下该按钮来调用。我试图通过情节提要制作 IBAction,也通过 addTarget 到按钮插座。两人都没有打电话。当我单击它时,我的按钮可以访问,它显示默认的触摸动画。同样在 viewDidLoad() 中打印按钮出口表示<UIButton: 0x17d25430; frame = (15 8; 39 30); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x17d25ae0>>
它不是零。
我的布局如下所示。
主屏幕:UIViewController、UITableViewDelegate、UITableViewDataSource、UIWebViewDelegate{}
- 在其中一个 mainScreens tableView 中是一个名为 videoViewCell 的 customCell,它通过以下方式实现:
let cell = NSBundle.mainBundle().loadNibNamed("VideoViewCell", owner: self, options: nil)!.first as! 视频视图单元
videoViewCell: UITableViewCell , UITableViewDelegate, UITableViewDataSource {} 有:
weak var delegate: ActivityDetailVideoCellDelegate?
...
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
delegate?.selectedCellAtIndex(indexPath.row)
}
...
protocol ActivityDetailVideoCellDelegate: class {
func selectedCellAtIndex(index: Int)
}
我的 mainScreen 类有:
extension MainScreen: ActivityDetailVideoCellDelegate {
func selectedCellAtIndex(index: Int) {
let youtubeLink: String = "http://www.youtube.com/embed/\(selectedVideo)"
let youtubePopup = YouTubePopUpController()
youtubePopup.view.frame = self.view.bounds
youtubePopup.view.alpha = 0
youtubePopup.view.transform = CGAffineTransformMakeScale(1.3, 1.3)
let code: String = "<iframe width=\(youtubePopup.webView.bounds.width) height=\(youtubePopup.webView.bounds.height) src=\(youtubeLink) frameborder=0 allowfullscreen></iframe> <style>body { margin: 0; padding: 0; }</style>"
youtubePopup.webView.loadHTMLString(code, baseURL: nil)
self.view.addSubview(youtubePopup.view)
UIView.animateWithDuration(0.25, animations: { () -> Void in
youtubePopup.view.alpha = 1
youtubePopup.view.transform = CGAffineTransformMakeScale(1, 1)
})
}
}
YouTubePopUpController:UIViewController:
@IBOutlet weak var backgroundView: UIView!
@IBOutlet weak var webView: UIWebView!
@IBOutlet weak var closeButton: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
print(closeButton)
closeButton.addTarget(self, action: #selector(self.closeButtonClicked(_:)), forControlEvents: .TouchUpInside)
}
@IBAction func closeButtonClicked(sender: AnyObject) {
print("close clicked")
UIView.animateWithDuration(0.25, animations: { () -> Void in
self.view.transform = CGAffineTransformMakeScale(1.3, 1.3)
self.view.alpha = 0
}) { (finished) -> Void in
self.view.removeFromSuperview()
}
}
