问题 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. But is there a way to do that ? Right now I implement didDismissWithButtonIndex delegate method to show UIActionSheet again after it was dismissed.

I want to use the method presentViewController, but the following code does not work (currently being called in the ActionSheet class): [self presentViewController:myViewController animated:YES]; I am a little confused regarding where I should call the method from (MainView or the ActionSheetDelegate).

问题 The default behavior for the UIActionSheet used to be that touching the background did not dismiss it, and in fact did nothing. But with iOS 7 touching the background is equivalent to pressing the cancelButton . I'm modifying some software that needs to be kept to the iOS 6 behavior. How can I keep touches of the background from dismissing the action sheet? 回答1: You can achieve this by not using a cancel button.

What I'd like to have is a pop up window (in my head I picture it as being translucent and dark gray). It will not take up the whole screen and the view underneath will still be visible. In the pop up section there will be a textfield (with several lines) and underneath this there will be a number of UISwitches. The pop up will be scrollable and will end with OK/Cancel buttons
