我需要知道没有越狱的 iDevice 上安装了哪些应用程序。我尝试了不同的方法，这似乎是最好的，但它不适用于 iOS 7。

BOOL APCheckIfAppInstalled(NSString *bundleIdentifier)
{
    static NSString *const cacheFileName = @"com.apple.mobile.installation.plist";
    NSString *relativeCachePath = [[@"Library" stringByAppendingPathComponent: @"Caches"] stringByAppendingPathComponent: cacheFileName];
    NSDictionary *cacheDict = nil;
    NSString *path = nil;
    // Loop through all possible paths the cache could be in
    for (short i = 0; 1; i++)
    {

        switch (i) {
            case 0: // Jailbroken apps will find the cache here; their home directory is /var/mobile
                path = [NSHomeDirectory() stringByAppendingPathComponent: relativeCachePath];
                break;
            case 1: // App Store apps and Simulator will find the cache here; home (/var/mobile/) is 2 directories above sandbox folder
                path = [[NSHomeDirectory() stringByAppendingPathComponent: @"../.."] stringByAppendingPathComponent: relativeCachePath];
                break;
            case 2: // If the app is anywhere else, default to hardcoded /var/mobile/
                path = [@"/var/mobile" stringByAppendingPathComponent: relativeCachePath];
                break;
            default: // Cache not found (loop not broken)
                return NO;
            break; }

        BOOL isDir = NO;
        if ([[NSFileManager defaultManager] fileExistsAtPath: path isDirectory: &isDir] && !isDir) // Ensure that file exists
            cacheDict = [NSDictionary dictionaryWithContentsOfFile: path];

        if (cacheDict) // If cache is loaded, then break the loop. If the loop is not "broken," it will return NO later (default: case)
            break;
    }

    NSDictionary *system = [cacheDict objectForKey: @"System"]; // First check all system (jailbroken) apps
    if ([system objectForKey: bundleIdentifier]) return YES;
    NSDictionary *user = [cacheDict objectForKey: @"User"]; // Then all the user (App Store /var/mobile/Applications) apps
    if ([user objectForKey: bundleIdentifier]) return YES;

    // If nothing returned YES already, we'll return NO now
    return NO;
}

BOOL APCheckIfAppInstalled(NSString *bundleIdentifier); // Bundle identifier (eg. com.apple.mobilesafari) used to track apps

    NSArray *bundles2Check = [NSArray arrayWithObjects: @"com.apple.mobilesafari", @"com.my.application", @"com.blahblah.nonexistent", nil];

    for (NSString *identifier in bundles2Check)

        if (APCheckIfAppInstalled(identifier))

            NSLog(@"App installed: %@", identifier);

        else

            NSLog(@"App not installed: %@", identifier);

如果您将应用程序提交给 Apple 以供批准，所有这些方法都将被拒绝。此外，所有应用程序都安装在自己的沙箱中，这意味着它们不能在自己的应用程序之外做任何事情。因此，如果没有越狱，使用记录在案的 API（您无权访问NSHomeDirectory()）并考虑到沙盒，就没有办法做到这一点。
