我正在实现基于MPMediaPickerController的应用程序。在那当我试图打开音乐应用程序时,它需要带我到“播放列表”选项卡,而不是显示“音乐”选项卡。为此,我使用选定的索引属性来制作它。但仍然无效。以下是我的代码,请问你们能否帮助我,这很紧急。MPMediaPickerController选择的索引不起作用
MPMediaPickerController *picker =
[[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic];
picker.delegate = self;
picker.allowsPickingMultipleItems = YES;
picker.prompt = NSLocalizedString (@"Select any song from the list", @"Prompt to user to choose some songs to play");
// The media item picker uses the default UI style, so it needs a default-style
// status bar to match it visually
[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated: YES];
picker.tabBarController.selectedIndex=1;
[picker.tabBarController.selectedViewController viewDidAppear:YES];
[self presentModalViewController: picker animated: YES];
[picker release];
谢谢, 钱德拉。
