有没有人知道我如何编写这个自定义警报控制器(特别是顶部区域) - 目前在Apple音乐应用程序中找到。也许有一个已知的库可以做到这一点。
我知道你是如何对动作控制器进行编码的?
let alertController = UIAlertController(title: nil, message: "Top Message Here", preferredStyle: .ActionSheet)
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { (action) in
// Drop View Pop up
}
alertController.addAction(cancelAction)
let action1 = UIAlertAction(title: "Action Title", style: .Default) { (action) in
//Code to Execute
}
alertController.addAction(action1)
self.presentViewController(alertController, animated: true) {
// ...
}

以下是一个例子:
@IBAction func show() {
let actionSheet = UIAlertController(title: "\n\n\n\n\n\n", message: nil, preferredStyle: .ActionSheet)
let view = UIView(frame: CGRect(x: 8.0, y: 8.0, width: actionSheet.view.bounds.size.width - 8.0 * 4.5, height: 120.0))
view.backgroundColor = UIColor.greenColor()
actionSheet.view.addSubview(view)
actionSheet.addAction(UIAlertAction(title: "Add to a Playlist", style: .Default, handler: nil))
actionSheet.addAction(UIAlertAction(title: "Create Playlist", style: .Default, handler: nil))
actionSheet.addAction(UIAlertAction(title: "Remove from this Playlist", style: .Default, handler: nil))
actionSheet.addAction(UIAlertAction(title: "Cancel", style: .Cancel, handler: nil))
presentViewController(actionSheet, animated: true, completion: nil)
}

如果您偏离UIKit
组件,我已为自定义操作表创建了library。它是用Swift编写的,允许您使用几种内置项类型创建自定义工作表。它也可以扩展和重新设计。
