问题:

I have code which simply display UIActionSheet on button click. but it will crash when I build it using XCode5.1 + iOS8beta in iPad.

below is a code I used to display UIActionSheet.

UIActionSheet *tmpActionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                                delegate:self
                                                       cancelButtonTitle:@"Cancel"
                                                  destructiveButtonTitle:nil
                                                       otherButtonTitles:
                                     @"Ok",
                                     nil];
    [tmpActionSheet showInView:self.view];

Note:
- It perfectly work with XCode6beta + iOS8beta (iPhone/iPad both)
- It perfectly work with XCode5.1 + iOS8beta (iPhone only)

Log while exception is came is as below.

Question :
1] Why my application is crash ?
2] Is it iOS8beta bug ?

Patch till apple fix this issue
Create Objective-C categor for UIActionSheet class

CODE :

#define SYSTEM_VERSION_EQUAL_TO(v)                  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)
#define SYSTEM_VERSION_GREATER_THAN(v)              ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN(v)                 ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v)     ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)

    }
}

回答1:

I also had the same problem. i used ShowFromBarButtonItem function instead of ShowInView Function.

[organizeActionSheet showFromBarButtonItem:btnAction animated:NO];

if use ShowFromRect or showFromBarButtonItem runtime exception will not come. i think it is a bug of IOS8 Beta, when i use ShowInView Runtime exception is coming.

This bug is not happening in IOS Beta 4..

I do get some warning messages in the debug window when built using Xcode 5.1, but the action sheet does appear. In iOS 8 beta 4, it appears as a small pop-up window outside of the view (at the side), whereas in iOS 7, it used to appear as buttons that slid up from the bottom of the view.



回答2:

I am having the same issue, and this is still 'broken' in beta 5. In my case though I am just getting a dimmed screen without action sheet instead of a crash.

Except showing an action sheet directly in a view on iPad is not a good design anyway. You should use popover containing an action sheet and pointing to the button or UI element that spawned the choice as Sabareesh suggested. Alerts are for messages that are disconnected from any UI elements, action sheets are always associated with an onscreen UI element as far as I know.



回答3:

I've seen the same problem for a while with showInView not working from IOS 8 Beta 2 through Beta 5. I just submitted bug report:17971746.



回答4:

I also get a crash on iOS8 final on iPad.

This is my simple workaround:
replace
[actionSheet showFromBarButtonItem:myButton animated:YES];
by
[actionSheet showFromRect:myButton.navBarView.frame inView:self.view animated:YES];



回答5:

according to this https://developer.apple.com/library/ios/documentation/Uikit/reference/UIActionSheet_Class/index.html Answer is from here: How to do "actionSheet showFromRect" in iOS 8?
