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：

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:)
