Question

数据来自解析器，如果文本超过120个字符，那么它应该附加＆＃34; ... ReadMore＆＃34;就像facebook一样。我有附加文本的代码，但不知道如何制作可点击的链接。我使用的是Swift Languange。

if cell!.bhikmangaTextlbl!.text!.utf16Count >= 120
    {
     var abc : String =  (cell!.bhikmangaTextlbl!.text! as 
    NSString).substringWithRange(NSRange(location: 0, length: 120))
     abc += " ...ReadMore"
      cell!.bhikmangaTextlbl!.text = abc

    }

Answer 1

您可以在此处使用属性字符串...并使文本的某些部分可点击

这里是Objective C代码。您可以为Swift编写相同的内容

NSDictionary *attribs = @{
                              NSForegroundColorAttributeName: BODY_FONT_COLOR,
                              NSFontAttributeName: [UIFont fontWithName:FontHelvetica size:AppFont16]
                              };
    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:ACCIDENT_DETECTION_AUTOMATIC_TEXT attributes:attribs];
    [attributedString addAttribute:NSLinkAttributeName
                             value:@"Accident detection"
                             range:[[attributedString string] rangeOfString:@"Read More"]];




    NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: LINKS_FONT_COLOR,
                                     NSUnderlineColorAttributeName: [UIColor clearColor],
                                     NSUnderlineStyleAttributeName: @(NSUnderlineStyleNone)};

    // assume that textView is a UITextView previously created (either by code or Interface Builder)
    self.accidentDetectionText.linkTextAttributes = linkAttributes; // customizes the appearance of links
    self.accidentDetectionText.attributedText = attributedString;

好吧，我宁愿添加一个名为＆＃34的额外标签;阅读更多＆＃34;并在其上添加点击手势以扩展第一个标签。

在120个字符后附加readmore标签，并使其在ios中可点击
