How to pass NSURL to view controller from delegate

Question

So my application opens a file format. Since the app is running it uses applicationWillEnterForeground to call application:openURL:sourceApplication:annotation:. Once I have my NSURL in my delegate my previous view opens and I have done anything with the NSURL.

My app of course is using a storyboard so I just can't call the XIB like most tutorials have you do. So my question how do I get that file to view controller to open and progress it?

Answer 1

You can create property in your AppDelegate.h file to hold the NSURL:

@property (nonatomic, string) NSURL *myURL;

And in

application:openURL:sourceApplication:annotation:

save the url to new property:

self.myUrl = url;

After that you can access the url from every single view controller in your app. Passing url from delegate is not good solution because when the

application:openURL:sourceApplication:annotation:

is called your view controller can be nil.
