iOS中用到文本属性Attributes的地方还是很多的，这里对文本属性做一些归纳，以免记不住用到的时候到处找资料：

如下是所有的文本属性：

NSFontAttributeName                    //设置字体大小NSParagraphStyleAttributeName          //设置段落格式NSForegroundColorAttributeName         //设置字体的颜色NSBackgroundColorAttributeName         //设置背景的颜色NSLigatureAttributeName                //设置连体字符NSKernAttributeName                    //设置文字之间的距离NSStrikethroughStyleAttributeName      //设置删除线的样式NSUnderlineStyleAttributeName          //设置下划线的格式NSStrikethroughColorAttributeName      //设置删除线的颜色NSStrokeColorAttributeName             //设置中空效果的填充颜色NSStrokeWidthAttributeName             //设置中空效果的宽度NSShadowAttributeName                  //设置阴影效果NSTextEffectAttributeName              //设置文本的特殊效果NSAttachmentAttributeName              //设置文本附件NSLinkAttributeName                    //设置超链接NSBaselineOffsetAttributeName          //设置基线偏移值NSUnderlineColorAttributeName          //设置下划线的颜色NSObliquenessAttributeName             //设置字体倾斜NSExpansionAttributeName               //设置文本扁平化（横向拉伸）NSWritingDirectionAttributeName        //设置文字的书写方向NSVerticalGlyphFormAttributeName       //设置文字的排版方向

下面是详细用法
-1. NSFontAttributeName //设置字体大小
