Question

I have two array one is NSMutableArray and one is NSArray i want to store the contents of NSMutableArray in NSArray but it is not working for me gives exception unrecognised selector sent.

myArray=[[NSArray alloc] initWithArray:appDelegate.surveyAnswersScreenOne];

Note, SurveyAnswerScreenOne is an NSMutableArray

Answer 1

You can do that in many ways –

NSArray * myArray = [appDelegate.surveyAnswersScreenOne copy];

NSArray * myArray = [NSArray arrayWithArray:appDelegate.surveyAnswersScreenOne];

NSArray * myArray = [[NSArray alloc]initWithArray:appDelegate.surveyAnswersScreenOne];

But first of all your appDelegate.surveyAnswersScreenOne should have objects in it.
