    • 如果iOS 7 SDK,在SpringBoard.app端有一个名为lock.aiff的声音文件.声音文件的路径如下.

    iPhoneSimulator7.0.sdk/System/Library/CoreServices/SpringBoard.app/lock.aiffs

    这是我的代码.

        NSString *path = [[NSBundle bundleWithIdentifier:@"com.apple.UIKit"] bundlePath];
    NSString *frameworkPath = [path stringByDeletingLastPathComponent];
    NSString *libraryPath = [frameworkPath stringByDeletingLastPathComponent];
    NSString *finalePath = [libraryPath stringByAppendingString:@"/CoreServices/SpringBoard.app/lock.aiff"];

    NSURL *fileURL = [NSURL fileURLWithPath:finalePath];
    SystemSoundID soundID;
    AudioServicesCreateSystemSoundID((__bridge_retained CFURLRef)fileURL,&soundID);
    AudioServicesPlaySystemSound(soundID);

    Value of the variable finalePath = "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.0.sdk/System/Library/CoreServices/SpringBoard.app/lock.aiff"

    但我无法在模拟器上播放此声音文件.另外,我无法播放SpringBoard.app中的任何声音文件.但我可以成功播放任何其他文件.例如,以下位置的声音文件播放效果很好.

    iPhoneSimulator7.0.sdk/System/Library/PrivateFrameworks/AOSNotification.framework/findme_alarm_2.aiff

    我的猜测是因为lock.aiffs在SpringBoard.app中,所以会引起某种问题.所以我怎样才能播放lock.aiff文件.

    • 由于iOS应用程序的沙盒特性,您无法访问其他应用程序包中的资源.

      但是,您可以播放系统声音,例如锁定声音,如下所示:

      NSURL *fileURL = [NSURL URLWithString:@"/System/Library/Audio/UISounds/lock.caf"]; 
SystemSoundID soundID;
AudioServicesCreateSystemSoundID((__bridge_retained CFURLRef)fileURL,&soundID);
AudioServicesPlaySystemSound(soundID);

      以下是您可以访问的iOS 7.0.2系统声音的完整列表:
