Get list of installed apps on iPhone

Solution 1:

No, apps are sandboxed and Apple-accepted APIs do not include anything that would let you do that.

You can, however, test whether a certain app is installed:

• if the app is known to handle URLs of a certain type
• by using [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"thisapp://foo"]

You can get a list of apps and URL schemes from here.

Solution 2:

For jailbroken devices you can use next snipped of code:

-(void)appInstalledList
{
 static NSString* const path = @"/private/var/mobile/Library/Caches/com.apple.mobile.installation.plist";

NSDictionary *cacheDict = nil;
BOOL isDir = NO;
if ([[NSFileManager defaultManager] fileExistsAtPath: path isDirectory: &isDir] && !isDir) 
{
    cacheDict = [NSDictionary dictionaryWithContentsOfFile: path];

    NSDictionary *system = [cacheDict objectForKey: @"System"]; // First check all system (jailbroken) apps
    for (NSString *key in system)
    {
        NSLog(@"%@",key);
    }
    NSDictionary *user = [cacheDict objectForKey: @"User"]; // Then all the user (App Store /var/mobile/Applications) apps

    for (NSString *key in user)
    {
        NSLog(@"%@",key);
    }
    return;
}
NSLog(@"can not find installed app plist");                   
}
