Question

My modal view controllers are being shown behind my UIActionSheet, and my UIActionSheet is not getting dismissed. I am using:

[self presentModalViewController:composeTweetView animated:YES];

To present my modal view controller.

My action sheet is being shown from the tabBar:

[actionSheet showFromTabBar:self.parentViewController.tabBarController.tabBar];

This code worked on iOS 4.0.

if (buttonIndex == 0) {
        if (self.isLoggedIn) {
            [FlurryAPI logEvent:@"ST_REPLY_CLICKED"];
            composeTweetView.isDirectMessage = FALSE;
            [self presentModalViewController:composeTweetView animated:YES];
            [composeTweetView release];
        }
        else {
            LoginViewController* loginView = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil];
            loginView.delegate = self;
            loginView.isPostingComment = TRUE;
            self.isReply = TRUE;
            [self presentModalViewController:loginView animated:YES];
            [loginView release];
            [composeTweetView release];
        }
    }

Summary:

I have a UIViewController that contains a UITabBar. I am presenting a UIActionSheet which has a few buttons that present a modal view controller. When the modal view controller is presented, the UIActionSheet should dismiss itself and the modal view should be on the top of the stack. The problem is, the UIActionSheet does not dismiss, and the modal view is loaded behind it. This problem did not occur up until iOS 4.2.1

Steps to Reproduce:

1. Create a TabBar project, setting
   your Base SDK to iOS 4.2.1
2. Create a button or trigger to show a UIActionSheet
3. Allow one of the buttons in the UIActionSheet to present a modal view controller using the syntax: [actionSheet showFromTabBar:self.parentViewController.tabBarController.tabBar];

Expected Results:

1. The UIActionSheet should dismiss itself, and the modal view should appear in front

Actual Results:

1. The UIActionSheet does not get dismissed and the modal view appears behind it.

Regression:

This problem was not apparent prior to iOS 4.2.1

Notes:
I have tried other ways of displaying the UIActionSheet all of which don’t work as intended:

//[actionSheet showInView:self.parentViewController.tabBarController.tabBar];
//[actionSheet showInView:[self.view window]];
//[actionSheet showInView:self.parentViewController.tabBarController.view];
//[actionSheet showInView:[UIApplication sharedApplication].keyWindow];

Answer 1

The problem has been resolved in iOS5.
