I have data being refreshed in a modalViewController and when that data gets refreshed, the parent controller needs to refresh its data as well. I tried doing a [tableView reloadData]; but it didn't work properly since the actual array values aren't being refreshed. Is there a way for me to reload a controller without the user seeing any...

The Apple documentation on the MPMediaPlaylist class is pre-iOS4, so it definitively states that you cannot write new playlists to iTunes on the phone with the SDK. However, with the iOS4 update, users can create and save new playlists on the phone. Is this functionality offered to developers as well? If so, could someone point me to app...

I have a TabBarController that sets the image for the tab like so, in the -init method: self.tabBarItem.image = [UIImage imageNamed:@"tabImage.png"]; I have a [email protected] file in the resource.

Push Notifications for a clients app were working fine on iOS 4 but when users update to iOS 4.01 they can no longer register for notifications. It looks like the phone running under iOS 4.01 is unable to generate a Device Token to give to the app. The app still shows up under the Settings->Notifications menu as being ON. Google tells ...

According to Apple... apps should reduce their memory footprint as much as possible when running in the "background" (suspended mode). I reduce the memory footprint of my app by releasing a bunch of 2D textures in ApplicationDidEnterBackground and reloading the same textures in ApplicationWillEnterForeground. Everything works for the m...

Or, should I just make images those dimensions and not worry about the resolution (i.e. leave it at the default 72)? I'm no...

Hi, I've figured out how I can get audio playing in the background on ios4, however I've noticed that some apps also replace the iPod dock icon with their own app icon. (Last.fm & Spotify for example). They are also able to use the dock media controls to pause and resume their streams. Does anyone know how to do this? Thanks ...
