Xcode 4.6 if statement with && -

-

my problem is

-(ibaction)setaction:(id)sender{      if ([labelone.text isequal: @"one"] && [labeltwo.text isequal: @"two"]) {         labelshow.text = @"yes works :)";     }    }

and if build it. show me error code: thread 1: signal sigbart

but works if this

-(ibaction)setaction:(id)sender{      if ([labelone.text isequal: @"one"]) {         labelshow.text = @"yes works :)";     }    }

what can do, first 1 works?:)

the sibabrt implies either labeltwo or labeltwo.text pointing bad memory.

first figure out pointer bad, , debug see why. also, provide crash log when possible. there should error message associated in debug output pane.

check out this debugging tutorial.
