@a. vural: [[MPMusicPlayerController iPodMusicPlayer] setVolume:1.0] works, BUT media must be played, otherwise system volume will be adjusted.

Workaround: play a sound file that is empty and adjust the volume at that time.

@Mitch: As far as I can tell, there isn’t even a method named -(void)mediaPicker in the demo project.

Thanks for the code, but I’m getting some errors in the -(void) mediaPicker method. It says request for member ‘musicPlayer’ in something not a structure or union.

Any idea why I’d that get that? I get it for the last 3 lines of the mediaPicker method… If I comment them out, there are no errors and the mediaPicker works great – except for the playback functionality of course.

Any help would be greatly appreciated!

Thanks for the reply. Another question.

After i have filled in the table view, is it possible to resize the table view such that its half of the screen, and maybe have some controls like buttons on the bottom half.

Thanks again:)

@Ching Hwee: I mentioned this briefly in my post. Create an MPMediaQuery and then use the results to fill your table view. It’s not a one-liner but not difficult to do.

Hi there.

Is there anyway that i can import the songs in the user’s library directly into a tableView instead of using the media picker and let the user choose?

Thanks

Shubham: there should be no difference in an OpenGL-based app. You can use the exact same calls. You can even use the media picker if you want. If you want to create your own OpenGL-based media picker, you have to build it from scratch, of course.

How can we get ipod song lists and other functionalities in an OPENGL iphone app??

Hi, I’ve developed a simple application to display the current song info. It works fine with the normal ipod app. However, when I use the iphone connected to my car radio and when it is remotely controlled by this, I get the following behaviour:
The notifcation handleNowPlayingItemChanged is received by my application, but the app does not get any info about the currently playing item.

Any ideas if this is normal behaviour when the iphone is connnected to another device or if I’m doing something wrong?

So, can I change the volume from any view? How can I access the current background music from a, lets say, a Settings viewcontroller?

Also, does it provide the same resources to play sound files from App bundle?

Thanks in advanced :)

Jóhann: Yes, I noticed the same. MPMediaQuery is really slow. I don’t know of any alternative, short of maintaining your own cached song database (e.g. with Core Data). I believe the iPod app does something like that. But how will you then get notified when the music library on the device has changed while your app is not running?

Did you run into any performance problems when using MPMediaQuery? I’ve been performing some tests and [query items] is painfully slow.

Do you know of any other method for getting a list of every song in the library?

What I observe with MPMediaItemPropertyLyrics: After syncing the iPod library, no lyrics are returned. Then, when you open a song in the iPod application on the iPhone and display its lyrics, only the lyrics of this song are returned.

I’m trying to use the MPMediaQuery to get all of my albums. It works fine, but sometimes, it’s get timed out. I get a notification to the console, but how can I reload the timed out items? Since it could be really bad, when I get timed out when I cache the items. :(
