iOS开发——NSArray中的字符串排序

　 NSArray *arr = @[@"fjhsf",@"wert",@"fdg",@"asd",@"fs gds",@"bfd sd",@"ref",@"hjk"];

    NSStringCompareOptions comparisonOptions = NSCaseInsensitiveSearch|NSNumericSearch|

    NSWidthInsensitiveSearch|NSForcedOrderingSearch;

    NSComparator sort = ^(NSString *obj1,NSString *obj2){

        NSRange range = NSMakeRange(0,obj1.length);

        return [obj1 compare:obj2 options:comparisonOptions range:range];

    };

    NSArray *resultArray = marr sortedArrayUsingComparator:sort];

    NSLog(@"字符串数组排序结果%@",resultArray);
