Sorting an NSArray of NSString

Question

Can someone please show me the code for sorting an NSMutableArray? I have the following NSMutableArray:

NSMutableArray *arr = [[NSMutableArray alloc] init];

It's pretty simple to write your own comparison method for strings:

@implementation NSString(compare)

-(NSComparisonResult)compareNumberStrings:(NSString *)str {
    NSNumber * me = [NSNumber numberWithInt:[self intValue]];
    NSNumber * you = [NSNumber numberWithInt:[str intValue]];

    return [you compare:me];
}
