【问题讨论】：
请参考此链接-***.com/questions/24366437/… 嗨 VijayKumar 为什么我需要这样做？这是一篇不同代码的新帖子 嗨 VijayKumar，你能帮我解决这个问题吗？ 【参考方案1】：上面提供的链接实际上是指Apple Doc，它已删除将子视图添加到UIActionSheet。在您的代码中，您通过将 UIPickerView 添加到 UIActionSheet 来做类似的事情。所以在 iOS8 以后，即使视图被添加到 UIActionSheet，在显示时返回的视图实际上是 nil。
为此，您可以使用 ActionSheetPicker-3.0。
实际上，它不再是UIActionSheet。但看起来完全一样，这就是它在 iOS8 上工作的原因。
如果这回答了您的问题，请告诉我！
【讨论】：
非常感谢您的快速响应，我已经下载了 ActionSheetPicker，这是一个非常聪明的解决方案，但我仍然有点困惑和迷茫，我该如何分配我的意见？谢谢 请 VijayKunar 告诉我如何锻炼这个“pickerView.dataSource = propertyDelegate;pickerView.delegate = propertyDelegate;[pickerView selectRow:[propertyDelegate index] inComponent:0 animated:NO];” on这个 ActionSheetPicker 我已经设法在我的项目中添加了 ActionSheetPicker，我不明白如何在这个例子中添加数据源，请你帮帮我 其实你什么都不用做。使用 ActionSheetStringPicker 执行完成块和取消块要简单得多。要指定数据源，您需要将 NSString 的 dataArray 对象传递给您的上述方法 我该怎么做，请 VijayKumar 帮我解决这个问题以上是关于带有 UIActionSheet IOS 8 的 UIPickerView 停止工作的主要内容，如果未能解决你的问题，请参考以下文章

iOS 8 之后，还能继续使用 UIActionSheet 和 UIAlertView 吗？
