问题描述
我正试图在popoverPresentationController的帮助下在ipad中实现动作表。一切工作正常,但我面临的一个问题是取消 样式按钮不在操作表中。 这是我的参考代码
@IBAction func logoutAction(_ sender: UIButton) {
let alertController = UIAlertController(title: "",message: "do you want to logout",preferredStyle: .actionSheet)
let yesAction = UIAlertAction(title: "logout",style: .destructive,handler: { (action) -> Void in
Singleton.sharedInstance.logoutButtonAction()
logEvent(label: "user_log_out")
})
let noAction = UIAlertAction(title: "cancel",style: .cancel,handler: { (action) -> Void in
self?.dismiss(animated: true,completion: nil)
})
alertController.addAction(yesAction)
alertController.addAction(noAction)
alertController.popoverPresentationController?.sourceView = self?.view
alertController.popoverPresentationController?.sourceRect = sender.frame
/* if let presenter = alertController.popoverPresentationController {
presenter.sourceView = self!.logoutButton
presenter.sourceRect = self!.logoutButton.bounds
}*/
self?.present(alertController,animated: true,completion: nil)
})
}
```
