[UILabel setAnswerText:]: unrecognized selector sent to instance 0x4916830'

Answer 1

You need to do [setAnswerText setText:@"my text"]; What you are doing now is wrong. The reason you get that exception is that UILabel does not have a class method called setAnswerText:.

Answer 2

answerText is the name of the label? then what are you trying to do?

If you want to access the answerText object (that being an instance of UILabel) you need to use self.answerText not [UILabel setAnswerText];

If you want to change the text in the label use:

answerText.text = @"Hello, this is my text";

or similar.
