我正在使用 OHAttributeLabel 将自定义链接添加到我的标签文本。我正在使用的代码粘贴在下面。它曾经与旧版本的 OHAttributed 标签 (2010) 一起使用，但是对于新版本（最近更新），我标签中的文本不再作为链接可点击。
谁能告诉我这里缺少什么？
// Set Question Label
Question *question = self._answerForCell.question;
NSString *questionText = [NSString stringWithFormat:@"Q: %@", question.text];
CustomOHAttributLabel *thisQuestionLabel = (CustomOHAttributLabel *)[self.contentView viewWithTag:QUESTIONLABEL_TAG];
//Set up dictionary for question
NSString *questionStr = [question.text stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSString *urlForQn = [NSString stringWithFormat:@"dailythingsfm://redirect_to/questions/%@/answers?text=%@&nickname=%@&question_id=%@&question_curious=%i&showEveryOneTab=%i", question.slug, questionStr, [[UserInfo sharedUserInfo] getNickname], question.qid, question.curious, 1];
NSString *qnStartIndex = @"0";
NSString *qnLength = [NSString stringWithFormat:@"%i", [questionText length]];
NSDictionary *qnDict = [NSDictionary dictionaryWithObjectsAndKeys:qnStartIndex, @"start", qnLength, @"length", urlForQn, @"url", nil];
NSArray *array = [NSArray arrayWithObject:qnDict];
[thisQuestionLabel setLabelwithText:questionText fontSize:QUESTION_FONT_SIZE andSubStringToURLArrayViaRange:array withHexColor:@"#555555"];
//Method to set the text in UILabel to a custom link
- (void)setLabelwithText:(NSString *)text fontSize:(CGFloat)fontSize andSubStringToURLArrayViaRange:(NSArray *)array withHexColor:(NSString *)textColor
{
NSMutableAttributedString *attrStr = [NSMutableAttributedString attributedStringWithString:text];
[attrStr setFont:[UIFont systemFontOfSize:fontSize]];
[attrStr setTextColor:[UIColor grayColor]];
[self removeAllCustomLinks];
for (NSDictionary *dict in array) {
NSString *start = [dict objectForKey:@"start"];
NSString *length = [dict objectForKey:@"length"];
NSString *url = [dict objectForKey:@"url"];
NSUInteger startIndex = [start intValue];
NSUInteger len = [length intValue];
NSRange range = NSMakeRange(startIndex, len);
[attrStr setFont:[UIFont boldSystemFontOfSize:fontSize] range:range];
[attrStr setTextColor:[UIColor colorWithHexString:textColor] range:range];
[self addCustomLink:[NSURL URLWithString:url] inRange:range];
}
self.attributedText = attrStr;
}
