How can I access the number of times other apps installed in my iPhone / iPad have been launched?

Question

Does the iOS' internal system keep track what apps have been launched including the number of times they have been launched since they're installed? I want to make an app that lists apps based on how often they're used.

In iOS you can keep track of how many times app launched with method

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

in AppDelegate.m file.

You can also check how many times application comes into foreground from background via

• (void)applicationWillEnterForeground:(UIApplication *)application

in same AppDelegate.m file.
