//Generate random number between 0 to mx-1 -(NSMutableArray *)GenerateRandom: (int)mx { NSMutableArray *rand = [[NSMutableArray alloc] initWithCapacity:mx]; for (int i=0;i<mx;i++) { NSInteger rnd; rnd = arc4random() % mx; while([rand containsObject:[NSNumber numberWithInt:rnd]]) { rnd = arc4random() % mx; } [rand addObject:[NSNumber numberWithInt:rnd]]; } return rand; }Suppose you need to call this method for 10 questions:

**NSMutableArray *randArray = [self GenerateRandom:10];**

Then It will generate array of random number between 0 and 9 and each number will be present in the array in random order.

Hope, It helps.
