Handling if user refused photo album access.

[johnqh]

Right now, there is an error message which doesn't mean anything for ordinary user "Album Error: User denied access - (null)", and title is stuck with "Loading..."

Since the code is in viewDidLoad, it cannot be overwritten by subclassing.

It would be nice to have the failure block call a method which can be overwritten by subclassing.

how to this error for you

[johnqh]

No need to do the error for me, just make it overwritable:

In viewDidLoad, change the assetGroupEnumberatorFailure block:

// Group Enumerator Failure Block
void (^assetGroupEnumberatorFailure)(NSError *) = ^(NSError *error) {

            [self onLoadError:error];
        };

then add a onLoadError: method

• (void)onLoadError:(NSError *)error
  {
  UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[NSString stringWithFormat:@"Album Error: %@ - %@", [error localizedDescription], [error localizedRecoverySuggestion]] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
  [alert show];

  NSLog(@"A problem occured %@", [error description]);

}
