错误： [UILabel copyWithZone:]: unrecognized selector sent to instance

12down voteaccepted

I guess this was one of those weird bugs with XCode that you can't trace or reproduce every time. I narrowed the issue down to one specific UILabel in the IB. As soon as I connect to to a UIOutlet UILabel *, I get this error.

On further investigation, it turns out that name title was causing the issue. I had the label declared as

IBOutlet UILabel *title;

As soon as change the name to gtitle, everything works as expected. Who knows?..

Yes, using title as a name for an IBOutlet variable cause big troubles! Thanks for this.... – tomsoft Jul 10 at 17:46

 

Just my problem, using title. The thing is, in another file I use title too, but all just fine. – Orlando Leite Aug 2 at 20:53

This was killing me... thank you! In hindsight, definitely a poor choice for the ivar, but it wasn't critical so I named it by default. Super poor error message from Xcode – MobileVet Nov 12 at 20:21
