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。

- (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];
}
