Get list of all installed apps

问题

I would like to get a list of all installed apps(NSArray). My app is a jailbreak app and is located in/Applications so Sandbox is no problem there. Is there any way to get a list of app store apps? I\'ve already seen this in other apps (Activator, SBSettings...). I have no idea how to do this, because all of the apps sandboxes have that huge code, so i don\'t know how it would be possible to access the .app folder inside the sandbox.

You can use this code snippet:

 #import "InstalledAppReader.h"

static NSString* const installedAppListPath = @"/private/var/mobile/Library/Caches/com.apple.mobile.installation.plist";

@interface InstalledAppReader()

-(NSArray *)installedApp;
-(NSMutableDictionary *)appDescriptionFromDictionary:(NSDictionary *)dictionary;

@end


@implementation InstalledAppReader

#pragma mark - Init
-(NSMutableArray *)desktopAppsFromDictionary:(NSDictionary *)dictionary
{
    NSMutableArray *desktopApps = [NSMutableArray array];

    for (NSString *appKey in dictionary)
    {
        [desktopApps addObject:appKey];
    }
    return desktopApps;
}

-(NSArray *)installedApp
{    
    BOOL isDir = NO;
    if([[NSFileManager defaultManager] fileExistsAtPath: installedAppListPath isDirectory: &isDir] && !isDir) 
    {
        NSMutableDictionary *cacheDict = [NSDictionary dictionaryWithContentsOfFile: installedAppListPath];
        NSDictionary *system = [cacheDict objectForKey: @"System"];
        NSMutableArray *installedApp = [NSMutableArray arrayWithArray:[self desktopAppsFromDictionary:system]];

        NSDictionary *user = [cacheDict objectForKey: @"User"]; 
        [installedApp addObjectsFromArray:[self desktopAppsFromDictionary:user]];

        return installedApp;
    }

    DLOG(@"can not find installed app plist");
    return nil;
}

@end

On jailbroken iPhones, you can just read the /Applications folder. All installed applications go there. Just list the directories in /Applications using NSFileManager:

NSArray *appFolderContents = [[NSFileManager defaultManager] directoryContentsAtPath:@"/Applications"];

After some research I have found a framework called iHasApp. Here is a good solution to return a dictionary with app name, identifier and icon: Finding out what Apps are installed

There's also the AppList library, which will do all of the dirty work for you: rpetrich/AppList It's used in a lot of Jailbreak tweaks, so I don't know why it wasn't suggested here before.

One way to get just AppStore apps would be to check the value of isSystemApplication for each app returned in the list. Those with the value set to NO are regular AppStore apps. There's also a function applicationsFilteredUsingPredicate:predicate, so perhaps it would even be possible to filter the list beforehand.
