NSDictionary *attributes = @{ NSFontAttributeName:[UIFont systemFontOfSize:14], NSParagraphStyleAttributeName:paragraphStyle, NSForegroundColorAttributeName:[UIColor colorWithRed:76./255. green:75./255. blue:71./255. alpha:1]  
                                 };  
 textView.attributedText = [[NSAttributedString alloc]initWithString:content attributes:attributes];  

 

当然也可以初始化一个NSMutableAttributedString,然后向里面添加文字样式,最后将它赋给textView的AttributedText即可 

复制代码
NSMutableAttributedString *atr = [[NSMutableAttributedString alloc]initWithString:detail];  
    [atr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:14] range:NSMakeRange(0, detail.length)];  
    textView.attributedText = atr;  

 

另外,对于textview中的链接样式,同样也可以定制 

复制代码
NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: [UIColor blueColor],  
                                     NSUnderlineColorAttributeName: [UIColor blackColor],  
                                     NSUnderlineStyleAttributeName: @(NSUnderlinePatternDash)};  
self.linkTextAttributes = linkAttributes;  

 

这里只是个简单的例子,具体还有很多属性可以自行参考头文件
