问题
I am trying to set my imageview:
detailedEventViewController.thumbnail.image = [UIImage imageNamed:@"amnesia.png"];
but get the error:
2011-01-08 09:53:24.153 HD Pocket Vacations[24697:207] -[DetailedEventViewController thumbnail]: unrecognized selector sent to instance 0x624d820
2011-01-08 09:53:24.247 HD Pocket Vacations[24697:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[DetailedEventViewController thumbnail]: unrecognized selector sent to instance 0x624d820'
My outlets are wired up correctly.
回答1:
There must be a problem with your "thumbnail" property.
As such, you'll need to check:
Whether it's been correctly defined and synthesized within your interface and implementation file(s).
Whether it's an UIImageView.
The spelling on all of the above.
