我使用UITextView,其中我显示NSAttributedString.我从服务器获取
HTML字符串.我使用以下代码将
HTML转换为NSAttributedString.
NSMutableAttributedString *attrib = [[NSMutableAttributedString alloc]initWithData:[strHTML dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding)} documentAttributes:nil error:nil];
要申请字体,我尝试下面2个代码.
[attrib addAttribute:NSFontAttributeName
value:myFont
range:NSMakeRange(0,attrib.length)];
对于自定义字符串,我先创建NSString下面,然后在NSAttributedString中隐藏
NSString *strHTML = [NSString stringWithFormat:@"<span style=\"font-family: myFont; font-size: 12\">%@</span>",@"my string"];
使用两个代码字体更改成功.但是不应用粗体和斜体下划线在NSAttributedString中应用.
我参考以下链接.
> iOS 7 using an HTML string as an NSAttributedString AND setting the font?
> ios7 font size change when create nsattributedstring from html
> How to add CSS of an html to NSAttributedString?
对于链接3,我应该从服务器端应用字体和标签,然后检索HTML字符串？
任何帮助将被贴上!!!
解决方法
最后我得到了答案.您可以检查拉姆答案(
Find attributes from attributed string that user typed),或者您可以简单地删除旧的字体属性,并使用以下代码应用新的字体.
NSDictionary *dictAttrib = @{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding)};
NSMutableAttributedString *attrib = [[NSMutableAttributedString alloc]initWithData:[yourHTMLString dataUsingEncoding:NSUTF8StringEncoding] options:dictAttrib documentAttributes:nil error:nil];
[attrib beginEditing];
[attrib enumerateAttribute:NSFontAttributeName inRange:NSMakeRange(0,attrib.length) options:0 usingBlock:^(id value,NSRange range,BOOL *stop) {
if (value) {
UIFont *oldFont = (UIFont *)value;
NSLog(@"%@",oldFont.fontName);
/*----- Remove old font attribute -----*/
[attrib removeAttribute:NSFontAttributeName range:range];
//replace your font with new.
/*----- Add new font attribute -----*/
if ([oldFont.fontName isEqualToString:@"TimesNewRomanPSMT"])
[attrib addAttribute:NSFontAttributeName value:font1 range:range];
else if([oldFont.fontName isEqualToString:@"TimesNewRomanPS-BoldMT"])
[attrib addAttribute:NSFontAttributeName value:font2 range:range];
else if([oldFont.fontName isEqualToString:@"TimesNewRomanPS-ItalicMT"])
[attrib addAttribute:NSFontAttributeName value:font3 range:range];
else if([oldFont.fontName isEqualToString:@"TimesNewRomanPS-BoldItalicMT"])
[attrib addAttribute:NSFontAttributeName value:font4 range:range];
else
[attrib addAttribute:NSFontAttributeName value:font5 range:range];
}
}];
[attrib endEditing];
谢谢.也许会帮助你
