iOS:个性化UITextView(缩进，行距，铺满)

总体来说个性化定制UITextView中的内容有两种方法：

1，从文件中读取内容到UITextView，这个个人感觉使用rtfd和rtf格式文件效果非常好。

2，使用NSAttributeString进行定制

具体方法如下: 

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc]init];
    paragraphStyle.lineHeightMultiple = 20.f;
    paragraphStyle.maximumLineHeight = 25.f;
    paragraphStyle.minimumLineHeight = 15.f;
    paragraphStyle.firstLineHeadIndent = 20.f;
paragraphStyle.alignment = NSTextAlignmentJustified;

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 

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 

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
