```
[DropboxClientsManager authorizeFromController:[UIApplication sharedApplication] controller:self openURL:^(NSURL *url) {
[AppViewDelegate openURL:url options:nil];
} browserAuth:NO];

```
The returned URL is: @"dbapi-2://1/connect? k=40l8o30x6jpwf8z&s=&state=oauth2:1BA467D3-65B0-4A14-B8FE-DEDFF7109DB3";
