有什么方法可以防止UIActionSheet在用户单击其中的按钮时被解雇？ [英] Any way to prevent UIActionSheet from being dismissed when user clicks a button in it?

问题描述

我在 UIActionSheet 中添加了 UIProgressView 来指示下载进度。因此，当用户单击其中的 download 按钮时，我不希望我的 UIActionSheet 被关闭。

I added a UIProgressView to my UIActionSheet to indicate the download progress. So I do not want my UIActionSheet to be dismissed when user click the download button in it.

但是有办法吗？

现在，我实现了 didDismissWithButtonIndex 委托方法，以在显示 UIActionSheet 后再次显示它。但是我希望有更好的方法。

Right now I implement didDismissWithButtonIndex delegate method to show UIActionSheet again after it was dismissed. But I was hoping there is a better way.

推荐答案

UIActionSheet 是模态视图，这意味着它完全阻止了UI。由于阻止UI被认为是一种不好的做法，因此不支持防止删除操作表。相反，您应该在操作表之外制作一个完全独立的进度指示器。

UIActionSheet is a modal view, which means that it blocks UI completely. Since blocking UI is considered a bad practice, preventing an action sheet from dismissing is not supported. Instead, you should make a completely separate progress indicator outside the action sheet.
