MPMediaPickerController customize the colors of the labels and icons

I need change the labels colors of MPMediaPickerController item, on iOS 7 , im using Xcode5, what can i do?.

My code of the creation of MPMediaPickerController is:

- (IBAction)addSongs:(id)sender {
  MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes:MPMediaTypeMusic];
  picker.delegate = self;
  picker.allowsPickingMultipleItems = YES;  
}

Thanks in advance.

Change your tab bar's tintColor using the appearance proxy, e.g.:

[[UITabBar appearance] setTintColor:[UIColor yellowColor]];

To change the tintColor of all views, including your label, you can do the following in your AppDelegate.m file:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{    
    [[UIView appearance] setTintColor:[UIColor yellowColor]];

    return YES;
}
