How to randomize an NSMutableArray? [duplicate]

Answer 1

Here's some sample code: Iterates through the array, and randomly switches an object's position with another.

for (int x = 0; x < [array count]; x++) {
    int randInt = (arc4random() % ([array count] - x)) + x;
    [array exchangeObjectAtIndex:x withObjectAtIndex:randInt];
}
