SDCAlertView capture of _userWindow race condition about sdcalertview HOT 4 CLOSED

Your first problem is easily explained by the fact that UIActionSheet uses a separate window itself, and like you found out, that window is the key window, which is then captured and returned to after dismissing the alert. If you want to make that work together, you'd probably have to use actionSheet:didDismissWithButtonIndex: to wait for the original window to become the key window again. Then that window is captured and will be returned to.

A workaround like yours is pretty fragile, as the window at index 0 may not be the window the user intends to return to either.

I'm not sure what's going wrong in your second example, though. Could you give a code example?

Looks like my second case is the same thing, as it is also triggered off the same action sheet. I'm surprised that viewDidAppear: is called on the presented modal vc before the _UIAlertOverlayWindow is gone. I agree the above solution is fragile, mostly why I opened the issue. Having said that, seems less fragile than without it? If it isn't a UIWindow, it is going to fail, unless you go the actionSheet:didDismissWithButtonIndex: route ... but if you do that, am I understanding you right, the window stored in _userWindow doesn't matter anyway?

Going to go with the actionSheet:didDismissWithButtonIndex: solution. Thanks for the help.

It takes the current keyWindow and returns to that after dismissing the alert. If that keyWindow is a window specifically created for UIActionSheet or UIAlertView, or any other system UI for that matter, that will be the window the user is returned to.

Figuring out what the user really intended to return to is a lot harder than simply saying "sorry, but you're doing something that's not supported". I would say that that's something you're running into, and the easiest way to make it work is probably actionSheet:didDismissWithButtonIndex:.

Thanks for your input, much appreciated!
