有的時(shí)候，我們的app需要顯示html標(biāo)簽的效果买窟，這個(gè)時(shí)候，如果需求不是特別復(fù)雜的話趁耗，我們都是可以使用textView來(lái)實(shí)現(xiàn)的疆虚。對(duì)冉Label也可以實(shí)現(xiàn)满葛，但是label很難實(shí)現(xiàn)超鏈接的點(diǎn)擊效果，所以篇亭，還是建議使用textView锄贷。
//modelData.content的數(shù)據(jù)其中一個(gè)是這種結(jié)構(gòu)：
//<a href="juzi://article/detail/native?id=37352">橘子君請(qǐng)大家參加party啦曼月，等大家來(lái)玩柔昼，點(diǎn)我報(bào)名哑芹，快來(lái)和橘子君一起玩耍吧聪姿！</a>
NSString * htmlString = modelData.content;
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUnicodeStringEncoding] options:@{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
self.textView.attributedText = attributedString;
//設(shè)置textView的高度末购，這里是根據(jù)文字計(jì)算的textView的高度
self.textViewHeight.constant = [PublicTool normalFontheightWithWidth:mScreenWidth - 24 andString:[attributedString string] andFontSize:14]+15;
self.textView.linkTextAttributes = @{
NSForegroundColorAttributeName:[UIColor colorFromRGB:0xfc5f59],//設(shè)置超鏈接顏色
NSUnderlineStyleAttributeName:@(NSUnderlineStyleNone),//設(shè)置超鏈接的下劃線為none虎谢，但是在ios10上無(wú)效，自己測(cè)試的無(wú)效曹货，原因沒(méi)找到呢
NSUnderlineColorAttributeName:[UIColor whiteColor]//無(wú)奈讳推，只得除此下策，改變下劃線顏色為白色礼饱，因?yàn)楸尘笆前咨柯浚跃碗[藏了下劃線
};//設(shè)置鏈接的文字顏色
normalFontheightWithWidth方法如下：（供參考）
//根據(jù)文字，寬度蝴韭，字體大小計(jì)算高度
+(CGFloat)normalFontheightWithWidth:(CGFloat)width andString:(NSString *)str andFontSize:(int)fontSize{
CGSize titleSize = [str boundingRectWithSize:CGSizeMake(width, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:fontSize]} context:nil].size;
return titleSize.height ;
}
