Objective-C Language NSMutableArray Move object to another index
Example
Move Blue to the beginning of the array:
NSMutableArray *myColors = [NSMutableArray arrayWithObjects: @"Red", @"Green", @"Blue", @"Yellow", nil];
NSUInteger fromIndex = 2;
NSUInteger toIndex = 0;
id blue = [[[self.array objectAtIndex:fromIndex] retain] autorelease];
[self.array removeObjectAtIndex:fromIndex];
[self.array insertObject:blue atIndex:toIndex];
myColors is now [@"Blue", @"Red", @"Green", @"Yellow"].
