from apple's documentation

NSArray *sortedArray = [array sortedArrayUsingComparator: ^(id obj1, id obj2) {

    if ([obj1 integerValue] > [obj2 integerValue]) {
        return (NSComparisonResult)NSOrderedDescending;
    }

    if ([obj1 integerValue] < [obj2 integerValue]) {
        return (NSComparisonResult)NSOrderedAscending;
    }
    return (NSComparisonResult)NSOrderedSame;
}];

Use Following code

   NSArray *unsortedArray = [NSArray arrayWithObjects:@"60", @"4", @"60", @"50", @"12", @"10", @"1", nil];
   NSArray *sortedArray = [unsortedArray sortedArrayUsingComparator:^(id firstObject, id secondObject) {
   return [((NSString *)firstObject) compare:((NSString *)secondObject) options:NSNumericSearch]; }];
   NSLog(@"Array is ::%@",sortedArray);
