Question

我有一个标题：@"This is what taxi drivers know that you don't"

'是撇号的正确UTF8表示吗？如果是这种情况，则JSON解析器正常工作，其UILabel无法正确显示UTF8。

if ([headline containsString:@"taxi"] == YES) {            
     news.headLine = [parsedNews objectForKey:@"head_line"];
}

在这个断点处，我看到上面给出的标题，如果您认为UTF8表示错误，我可以在之后发布JSON解析器代码。

NSString - ＆gt;解码为UTF8 NSData - ＆gt; NSAttributedString - ＆gt; NSString

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSString *string = @"This is what taxi drivers know that you don&#039;t";
    NSString *parsed = [self urlDecodeString:string usingEncoding:NSUTF8StringEncoding];
    NSLog(@"parsed: %@", parsed);
    // parsed: This is what taxi drivers know that you don't
}

- (NSString *)urlDecodeString:(NSString *)string usingEncoding:(NSStringEncoding)encoding
{
    NSDictionary *options = @{NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute:@(encoding)};
    NSData *data = [string dataUsingEncoding:encoding];
    NSAttributedString *attString = [[NSAttributedString alloc] initWithData:data options:options documentAttributes:nil error:nil];
    return [attString string];
}

UTF8不会显示在UILabel中
