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

//段落样式
NSMutableParagraphStyle *myStyle = [[NSMutableParagraphStyle alloc]init];
//行间距
myStyle.lineSpacing = 10;
//段落间距
myStyle.paragraphSpacing = 20;
//对齐方式
myStyle.alignment = NSTextAlignmentLeft;
//指定段落开始的缩进像素
myStyle.firstLineHeadIndent = 20;
//调整全部文字的缩进像素
