com.apple.mobile.installation.plist para iPhone 4

Question

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

// Implementation

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];
                NSLog(@"%@", path);
                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];
                NSLog(@"%@", path);
                break;
            case 2: // If the app is anywhere else, default to hardcoded /var/mobile/
                path = [@"/var/mobile" stringByAppendingPathComponent: relativeCachePath];
                NSLog(@"%@", path);
                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;
    }

    NSLog(@"file find success");

    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;
}

- (void)viewDidLoad
{
    NSArray *bundles2Check = [NSArray arrayWithObjects: @"com.apple.mobilesafari", @"com.yourcompany.yourselfmadeapp", @"com.blahblah.nonexistent", nil];
    for (NSString *identifier in bundles2Check)
        if (APCheckIfAppInstalled(identifier))
            NSLog(@"App installed: %@", identifier);
        else
            NSLog(@"App not installed: %@", identifier);
    [super viewDidLoad];
}

Quiero verificar qué aplicación está instalada en mi iPhone 4, pero no pudo encontrar la ruta correcta. /var/mobile/Library/Caches/com.apple.mobile.installation.plist

Está funcionando en mi iPad 2 de jailbreak pero no en mi iPhone 4.

¿Cambió Apple donde está el com.apple.mobile.installation.plist?

Muchas gracias

Debido al Sandboxing de Apple Application, no puede consultar nada fuera de su propio directorio de aplicaciones (Sandbox).

Esto funcionará en un dispositivo roto de la cárcel porque elimina las funciones de sandboxing de la aplicación del sistema operativo.
