Question

我似乎找不到可以让我执行以下操作的好文档：

我有一堆UTF-8字符串JSON'ed到我的iPhone应用程序并显示到UITableView。当用户点击某个项目时，我想要一个UIActionSheet来通知他们他们选择的类别。

问题在于，虽然汉字在UITableView中显示没有问题，但它们在UIActionSheet中显示为UTF-8字符。有没有办法将它从UTF-8转换成繁体中文字符？

我试图这样做，但它不起作用：

const char *subCatName = [[thirdParamStringArr objectAtIndex:1] UTF8String];
    NSString *subCatSelectedConverted = [[NSString alloc] initWithUTF8String:subCatName];       

    NSString *actionSheetTitle = [@"You have selected " stringByAppendingString:subCatSelectedConverted];

    NSString *actionSheetTitleFinal = [actionSheetTitle stringByAppendingString:@", proceed to upload to selected subcategory?"];

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:actionSheetTitleFinal delegate:self cancelButtonTitle:@"Proceed to Upload" destructiveButtonTitle:@"Cancel" otherButtonTitles:nil];

提前致谢！

好的，经过进一步调查后，这就成了伎俩：

NSString *subCatSelectedName = [[thirdParamStringArr objectAtIndex:1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];


        NSString *actionSheetTitle = [@"You have selected '" stringByAppendingString:subCatSelectedName];

        NSString *actionSheetTitleFinal = [actionSheetTitle stringByAppendingString:@"', proceed to upload to selected subcategory?"];

        UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:actionSheetTitleFinal delegate:self cancelButtonTitle:@"Proceed to Upload" destructiveButtonTitle:@"Cancel" otherButtonTitles:nil];

这就是诀窍：
