应用加载时播放声音

Question

尝试在应用加载时播放声音

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    //sleep(2);
    [NSThread sleepForTimeInterval:2.0];

    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"austinpowers", CFSTR("wav"), NULL); 

    if (soundFileURLRef) {
        CFStringRef url = CFURLGetString(soundFileURLRef);
    }
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);



    // Override point for customization after application launch.

    // Add the view controller's view to the window and display.
    [self.window addSubview:viewController.view];
    [self.window makeKeyAndVisible];

    return YES;
}

它会播放声音，但仅在加载墙纸（default.png）消失时才播放。 如果有人可以帮助我，或为我指明正确的方向

谢谢

Answer 1

不要使用Default.png，而是创建您的自定义启动屏幕视图控制器，您可以在其中显示图像并播放声音。

Answer 2

通过在AppDelegate.m文件中执行以下操作为我解决了此问题

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions {

   NSURL *clip = [[NSBundle mainBundle] URLForResource: @"intro" withExtension:@"caf"];
   self.startupPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:clip error:NULL];
   [self.startupPlayer play]; 

}

这也可能对您有用。
