Question

2. - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url

How to know in didFinishLaunchingWithOptions method if application was opened from URL or not. May be there are some launching options which I miss?

Answer 1

You can inspect launchOptions passed to - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions.

Look for section Launch Options Keys in reference docs, specifically UIApplicationLaunchOptionsURLKey

Answer 2

If your app has been launch from a URL You will find a

UIApplicationLaunchOptionsURLKey 

in the launchOptions Dictionary of - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

On a related note the handleOpenURL: method is deprecated, you should use:

-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
