How do I tell if app has been opened without URL?

Question

I know I can check if a URL has been used to open my application, like so:

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

... but how do I check if the user has only returned to the app (and update my interface accordingly), without a URL being used? The use case is when logging in to Facebook or Twitter via Safari, and then user just goes back to the app instead.

Use applicationDidBecomeActive or applicationWillEnterForeground

Is an answer starting with "I think" really an answer? – Sandro Meier Feb 06 '14 at 10:18

To answer Sandros Question: [Exhibit 1](http://stackoverflow.com/a/4945377/457406), [Ex. 2](http://stackoverflow.com/a/5080290/457406), [Ex. 3](http://stackoverflow.com/a/3726516/457406), [Ex. 4](http://stackoverflow.com/a/6889604/457406), [Ex. 5](http://stackoverflow.com/a/5729092/457406), [Ex. 6](http://stackoverflow.com/a/5542121/457406). Obviously it is possible to start an answer with "I think". SCNR ;-) – Matthias Bauch Feb 06 '14 at 10:32
