-canOpenURL: failed for URL:
Hi!
I get the following in the console:
What could be the problem?
Please, help.
The canOpenURL messages are expected, and can be ignored, since the "(null)" error indicates that nothing went wrong. Your plist also looks correct.
The "view is not in the window hierarchy" error message is likely indicating why the authorization view isn't being shown. It is indicating that your ViewController isn't in the window hierarchy. It appears your ViewController wasn't presented (or was already dimissed). The screenshot seems to support that, as it doesn't show anything, such as the button that would trigger your myButtonInControllerPressed. You'll need to make sure your ViewController is presented and not dismissed. Exactly how you do that would be specific to your app, and is outside the scope of Dropbox API support, so I'm afraid I can't offer much more specific guidance.

Thank you friend! I changed the place of the function authorizeFromController:controller:openURL call and it all worked!
It's my .plist:
