List the Versions of all the applications installed in iOS device programmatically

Question

I need to get the Versions of all the installed applications programmatically for non-jailbroken iOS devices. Is it Possible to achieve this?

Answer 1

That's possible, please try the below code.

Class LSApplicationWorkspace_class = objc_getClass("LSApplicationWorkspace");
    NSObject* workspace = [LSApplicationWorkspace_class performSelector:@selector(defaultWorkspace)];

    for (LSApplicationProxy *apps in [workspace performSelector:@selector(allApplications)])
    {         
        NSString *localizedName = apps.localizedName;

        if([apps.applicationType isEqualToString:@"User"])
        {
            NSLog(@"\nlocalizedName: %@",localizedName);
            NSLog(@"minimumSystemVersion: %@",apps.minimumSystemVersion);
            NSLog(@"fileSharingEnabled: %d",apps.fileSharingEnabled);
            NSLog(@"sdkVersion: %@",apps.sdkVersion);
            NSLog(@"teamID: %@",apps.teamID);
        }
    }

For this you need to place 4 classes in your app:

LSApplicationWorkspace, LSResourceProxy, LSBundleProxy, LSApplicationProxy.

In iOS8 and before, we can use canOpenUrl to get installed applications which registered schemes. In iOS9, you must add a "white list" into your info.plist file. Only the application in the "white list" can be checked. And the limit count of the "white list" is 50. So you'd better jailbreak your device.
