Question

I’m having some trouble with the handleOpenURL method in my app delegate. I have a rootviewcontroller that should be shown normally, but when a file is opened in my app, I need the handleOpenURL method to present a new viewcontroller and send the url info. The problem is I can’t present a modal view controller from my app delegate. Also, when I try to call a method in my rootviewcontroller to present the modalviewcontroller I get

 Warning: Attempt to present ... whose view is not in the window hierarchy!

So, I guess I’m just looking for a solution that will present a new modal view controller and pass the url information to that class. This is the app delegate method.

- (void)handleOpenURL:(NSURL *)url {

}

Thanks for your help

Answer 1

In your RootViewController,Create an instance of appDelegate just like

 YourAppDelegate *appDelegate = (YourAppDelegate *)[[UIApplication sharedApplication]delegate];
    appDelegate.rootViewControllerInstance = self;

then subject

[appDelegate handleOpenURL:yourURL];

also create a callBackFunction eg:

-(void)callBack:(NSUrl *)url;

Now in appDelegate class create a property of your RootViewController

and in appDelegate your function as specified this way..

- (void)handleOpenURL:(NSURL *)url {
[rootViewControllerInstance callBackUrl:url];
}
