解决方案二：
有的，出现上面的效果，我代码这样模仿你们写，传入装着好友名字的数组，没效果if (goodFriendName.count!=0) {        for (TXGoodFriendModel *goodFriendModel in goodFriendName) {            NSString *firstLetter = [ChineseToPinyin pinyinFromChineseString:goodFriendModel.nickname];            NSInteger section = [indexCollation sectionForObject:[firstLetter substringToIndex:1] collationStringSelector:@selector(uppercaseString)];                        NSMutableArray *array = [sortedArray objectAtIndex:section];            [array addObject:goodFriendModel];        }            }        for (int i = 0; i < [sortedArray count]; i++) {                NSArray *array = [[sortedArray objectAtIndex:i] sortedArrayUsingComparator:^NSComparisonResult(TXGoodFriendModel *obj1, TXGoodFriendModel *obj2) {            NSString *firstLetter1 = [ChineseToPinyin pinyinFromChineseString:obj1.nickname];            firstLetter1 = [[firstLetter1 substringToIndex:1] uppercaseString];                        NSString *firstLetter2 = [ChineseToPinyin pinyinFromChineseString:obj2.nickname];            firstLetter2 = [[firstLetter2 substringToIndex:1] uppercaseString];                        return [firstLetter1 caseInsensitiveCompare:firstLetter2];        }];                        [sortedArray replaceObjectAtIndex:i withObject:[NSMutableArray arrayWithArray:array]];    }DLog(@"ssssssssss===%@",sortedArray);    //名字分section    for (EMBuddy *buddy in dataArray) {        //getUserName是实现中文拼音检索的核心，见NameIndex类        DLog(@"拼音===%@",buddy.username);        NSString *firstLetter = [ChineseToPinyin pinyinFromChineseString:buddy.username];        NSInteger section = [indexCollation sectionForObject:[firstLetter substringToIndex:1] collationStringSelector:@selector(uppercaseString)];                NSMutableArray *array = [sortedArray objectAtIndex:section];        [array addObject:buddy];    }// //   每个section内的数组排序  //  DLog(@"ssssssssss===%@",sortedArray);    for (int i = 0; i < [sortedArray count]; i++) {                NSArray *array = [[sortedArray objectAtIndex:i] sortedArrayUsingComparator:^NSComparisonResult(EMBuddy *obj1, EMBuddy *obj2) {            NSString *firstLetter1 = [ChineseToPinyin pinyinFromChineseString:obj1.username];            firstLetter1 = [[firstLetter1 substringToIndex:1] uppercaseString];                        NSString *firstLetter2 = [ChineseToPinyin pinyinFromChineseString:obj2.username];            firstLetter2 = [[firstLetter2 substringToIndex:1] uppercaseString];                        return [firstLetter1 caseInsensitiveCompare:firstLetter2];        }];                        [sortedArray replaceObjectAtIndex:i withObject:[NSMutableArray arrayWithArray:array]];    }
