效果:

1.使用

//模擬資料

-(void)loadData

{

NSArray *dataArr = @[

@"比昂",@"阿狸",@"阿三",@"小明",@"張三",@"秋秋",@"波比",@"蘇三",@"饅頭",@"彩筆",@"咪咪",@"蔡芯",@"成龍",@"陳鑫",@"陳丹",@"成名",@"阿偉",@"阿姨",@"芳仔",@"房祖名",@"方大同",@"芳芳",@"範偉",@"郭靖",@"郭美美",@"過兒",@"過山車"

];

NSLog(@"原始資料 ==>> %@",dataArr);

_MyData = [self Transformation:dataArr];

NSLog(@"資料轉換 ==>> %@",_MyData);

[self.MyTableViewreloadData];

}

2.核心程式碼 （排序）

- (NSMutableArray *)Transformation:(NSArray *)dataArray

{

NSMutableArray *TwoArr = [NSMutableArrayarray];

for (NSString *TransformationStr in dataArray)

{

NSMutableString *pinyin = [TransformationStr mutableCopy];

CFStringTransform

CFStringTransform((__bridgeCFMutableStringRef)pinyin, NULL, kCFStringTransformStripCombiningMarks, NO);

[TwoArr addObject:pinyin];

}

NSMutableArray *ThreeArr = [NSMutableArrayarray];

for (__strong NSString *ScreenStr in

{

ScreenStr = [ScreenStr substringToIndex:1];

if (ThreeArr.count == 0)

{

[ThreeArr addObject:ScreenStr];

}

else

{

BOOL bl = [ThreeArr containsObject:ScreenStr];

if (!bl)

{

[ThreeArr addObject:ScreenStr];

}

}

}

NSArray *FourArr = [ThreeArr sortedArrayUsingSelector:@selector(compare:)];

NSMutableArray *MyArr = [NSMutableArrayarray];

for (NSString *str in FourArr)

{

NSMutableDictionary *dic = [NSMutableDictionarydictionary];

[dic setObject:str forKey:@"title"];

NSMutableArray *arr = [NSMutableArrayarray];

for (int i = 0; i < TwoArr.count; i++)

{

NSString *missstr = TwoArr[i];

missstr = [missstr substringToIndex:1];

if ([str isEqualToString:missstr])

{

[arr addObject:dataArray[i]];

}

}

[dic setObject:arr forKey:@"info"];

[MyArr addObject:dic];

}

return MyArr;

}
