MPMediaItem

[Raggou]

the error is at MPMediaItem * item = [self getARandomTrack];
What am in doing wrong?

-(IBAction)playSong:(id)sender{
    
	
	MPMediaItem * item = [self getARandomTrack];
	MPMediaItemCollection * collection = [[MPMediaItemCollection alloc] initWithItems:[NSArray arrayWithObject:item]];
	
	MPMusicPlayerController *myPlayer = [MPMusicPlayerController applicationMusicPlayer];
	
	[myPlayer setQueueWithItemCollection:collection];
	[collection release];
	[myPlayer play];

	}
	
	[musicPlayer setQueueWithItemCollection:collection];
	[collection release];
	[musicPlayer play];
	
}

-(MPMediaItem*) getARandomTrack
{
	MPMediaQuery *everything = [[MPMediaQuery alloc] init];
	// Get all Media Items into an Array (Fast)
	NSArray *allTracks = [everything items];
	// Check we have enough Tracks for a Random Choice
	if ([allTracks count] < 2)
	{
		return nil;
	}
	// Pick Random Track
	int trackNumber = arc4random() % [allTracks count];
	MPMediaItem *item = [allTracks objectAtIndex:trackNumber];
	// Display and Return
	return item;

}

Can you be more specific about "the error" ? Is this a compiler error? If yes, then what does the compiler error message say?

file://localhost/Developer/Applications/Music/Music/MusicViewController.m: warning: Semantic Issue: Instance method '-getARandomTrack' not found (return type defaults to 'id')

Any idea?

Did you declare getRandomTrack in your .h file?
