You can try to do your job (presenting view controller) in

- (void)      actionSheet:(UIActionSheet *)actionSheet
didDismissWithButtonIndex:(NSInteger)buttonIndex {}

instead of

- (void) actionSheet:(UIActionSheet *)actionSheet
clickedButtonAtIndex:(NSInteger)buttonIndex {}

@LeoNatan's solution just block the UI at main thread, so it'll also make sure the view controller will be presented after the action sheet was dismissed.

Answer 2

Try

[[NSOperationQueue mainQueue] addOperationWithBlock:^{
    // action sheet presentation

    // or alert view presentation
}];

Answer 3

Issuing a

[self.navigationController dismissViewControllerAnimated:YES completion:nil];

on

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex 

before trying to present another modal view worked for me.
