ios – 警告：UIAlertController已经呈现

概述我是 swift和XCode的新手所以请原谅我可能非常混乱的代码！ 运行我的代码时,我收到以下警告：     警告：尝试出示已经出现的内容 我已经检查了论坛并发现了一个关于该问题的帖子….我应用了建议的帮助,如： if presentedViewController !== nil { self.presentViewController(alertController, animate 我是 swift和XCode的新手所以请原谅我可能非常混乱的代码！
运行我的代码时,我收到以下警告：
警告：尝试出示已经出现的内容

我已经检查了论坛并发现了一个关于该问题的帖子….我应用了建议的帮助,如：

if presentedVIEwController !== nil {     self.presentVIEwController(alertController,animated: true,completion: nil)} else{     self.dismissVIEwControllerAnimated(false,completion: nil)     self.presentVIEwController(alertController,completion: nil)}

但是,它仍然给了我同样的警告….所以我想我一定做错了.如果有人可以帮助我,那将是很棒的:)如果有任何关于我如何“清理”我的代码的建议,我感激不尽:)
