Well In your XIB select you button then as attached in the screens shot follow the steps:-

Now in your header and implementation file create property and synthesize variable of BOOL isEnable;
And on the basis of your string count set it NO and YES.

you can use this method:

-(void) observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context

in this one you can enable and disable cell according the value in key path

Buddy, this does not answers the question... It needs to be binded, not triggered though method call. – Marcelo Aug 18 '14 at 21:25
