What is really strange is the sample app demonstrating how to use MPMediaPickerController, http://developer.apple.com/library/ios/#samplecode/AddMusic/Introduction/Intro.html works! This sample app was last updated on oct 1 2009.

I have compared the sample app and its Xcode project settings to my app and can not figure out what the difference is?

The only difference I have found is the sample app does not set the deployment target. I set my mine to 4.3. (even when I do not set it I still crash). I also noticed in the source code they tweak the status bar.

// The media item picker uses the default UI style, so it needs a default-style

// status bar to match it visually

#warning clean up debug

UIStatusBarStyle statusBarStyle = [[UIApplication sharedApplication] statusBarStyle];

SCILog(@"statusBarStyle = %d", statusBarStyle);

[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated: YES];

[self presentModalViewController:mediaPicker animated:YES];

This did not resolve the problem.

I checked to make sure I am using the same frameworks as the addMusic sample app.

I also noticed that sample addMusic app lets users down load songs from the MPMediaPickerController.

I tried setting mediaPicker.showsCloudItems = YES;and NO; still crashes

The sample app sets [mediaPicker setAllowsPickingMultipleItems:YES]; I still crash no matter how this is set.
