I believe so, since MyViewController is declared as a
FilePickerDelegate. When MyViewController instance creates a picker,
it does so as follows:
// MyViewController.m. MyViewController is a FilePickerDelegate.
- (void) changeSrcFileTapped:(id)sender
{
FilePicker* picker = [[FilePicker alloc] initWithDelegate:self
withContext:0];
[self presentModalViewController:picker animated:YES];
}
Back trace is below. Its basically useless to me since there is a call
graph, but very few symbols (I did a full install of Xcode???).
Is there anything special that needs to be done with IB? Perhaps a
missing IBOutlet?
Thanks for any help.
Jeff
