iOS 数组内中英文混合排序

NSInteger sortObjects(id obj1, id obj2,void *context)
{
    NSMutableString * str1 = [[NSMutableString alloc]initWithString:obj1];
    if (CFStringTransform((__bridge CFMutableStringRef)str1, 0, kCFStringTransformMandarinLatin, NO)) {
    }

    NSMutableString * str2 = [[NSMutableString alloc]initWithString:obj2];
    if (CFStringTransform((__bridge CFMutableStringRef)str2, 0, kCFStringTransformMandarinLatin, NO)) {
    }
    return [str1 localizedCompare:str2];
}
//先转为拼音，然后再进行排序。上面是进行转拼音，然后再排序的过程。

[otherNameArr sortUsingFunction:sortObjects context:NULL];//数组进行调用。

然后就完了。得到的数组就是从A~Z的过程了。

　　例子：

- (void)viewDidLoad {
    [super viewDidLoad];

    NSMutableArray * arr = [NSMutableArray arrayWithObjects:@"中文",@"linxl",@"唐唐唐",@"abc", nil];
    [arr sortUsingFunction:sortObjects context:NULL];
    NSLog(@"arr - %@",arr);
}

NSInteger sortObjects(id obj1, id obj2,void *context)
{
    NSMutableString * str1 = [[NSMutableString alloc]initWithString:obj1];
    if (CFStringTransform((__bridge CFMutableStringRef)str1, 0, kCFStringTransformMandarinLatin, NO)) {
    }

    NSMutableString * str2 = [[NSMutableString alloc]initWithString:obj2];
    if (CFStringTransform((__bridge CFMutableStringRef)str2, 0, kCFStringTransformMandarinLatin, NO)) {
    }
    return [str1 localizedCompare:str2];
}

　　打印：

2016-04-26 16:51:15.350 dd[65248:767376] arr - (
    abc,
    linxl,
    "\U5510\U5510\U5510",
    "\U4e2d\U6587"
