案例1：修改文本字体大小、颜色属性

比如文本展示为姓名和性别，但是我们不能排除姓名会很长，所以此刻的lable宽度我们就不能写死，换句话说lable的宽度根据文本的内容来定

我经常用两种方式解决：

1.前面文章已经涉及：lable自适应http://blog.csdn.net/tuwanli125/article/details/51003798

2.就是使用NSMutableAttributedString属性给infoL设置文本

NSString *infoStr = [NSStringstringWithFormat:@"%@ %@",name,sex];

NSMutableAttributedString *infoAttStr = [[NSMutableAttributedStringalloc] initWithString:infoStr];

NSArray *colorArr =@[[UIColorcolorWithRed:0/255.0green:168/255.0blue:255/255.0alpha:1.0],[UIColorcolorWithRed:153/255.0green:153/255.0blue:153/255.0alpha:1.0]];

－－－－－－－－修改姓名的颜色，字体大小－－－－－－

[infoAttStr addAttribute:NSForegroundColorAttributeNamevalue:colorArr[0]range:NSMakeRange(0,name.length)];

[infoAttStr addAttribute:NSFontAttributeNamevalue:[UIFontsystemFontOfSize:15]range:NSMakeRange(0,name.length)];

－－－－－－－－修改性别的颜色，字体大小－－－－－－

[infoAttStr addAttribute:NSFontAttributeNamevalue:[UIFontsystemFontOfSize:12]range:NSMakeRange(name.length+1,sexStr.length)];

[infoAttStr addAttribute:NSForegroundColorAttributeNamevalue:colorArr[1]range:NSMakeRange(name.length+1,sexStr.length)];

[self.infoL setAttributedText:infoAttStr];

这样一个文本就可以了，简单快捷

案例2：文本行间距

remindLabel.text = @""(一堆文字，此处省略一万字)

NSMutableAttributedString *attributedString = [[NSMutableAttributedStringalloc]initWithString:remindLabel.text];;

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStylealloc]init];

[paragraphStyle setLineSpacing:9];

paragraphStyle.maximumLineHeight = 60;  //最大的行高

[paragraphStyle setFirstLineHeadIndent:30];//首行缩进

[attributedString addAttribute:NSParagraphStyleAttributeNamevalue:paragraphStylerange:NSMakeRange(0, remindLabel.text.length)];

remindLabel.attributedText = attributedString;

文本行间距 以及自定义高度

NSMutableAttributedString * strAttebute = [[NSMutableAttributedString alloc] initWithString:check1];

//设置行间距

NSMutableParagraphStyle * paragraphStlyle = [[NSMutableParagraphStyle alloc] init];

[paragraphStlyle setLineSpacing:IPHONEHIGHT(10)];

[strAttebute addAttribute:NSParagraphStyleAttributeName value:paragraphStlyle range:NSMakeRange(0, check1.length)];

c2ell.labelText.attributedText = strAttebute;

CGSize contentSize = [c2ell.labelText.text  boundingRectWithSize:CGSizeMake(ScreenWidth-IPHONEWIDTH(28*3+140),MAXFLOAT ) options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:IPHONEWIDTH(30)],NSParagraphStyleAttributeName:paragraphStlyle} context:NULL].size;

c2ell.labelText.size =CGSizeMake(contentSize.width, contentSize.height);

案例3：添加下划线

我给按钮添加下滑线，比如按钮显示文本为电话号码，点击就可以拨打电话

NSMutableAttributedString *str = [[NSMutableAttributedStringalloc]initWithString:_phoneBtn.titleLabel.text];

NSRange strRange = {0,[strlength]};

[str addAttribute:NSUnderlineStyleAttributeNamevalue:[NSNumbernumberWithInteger:NSUnderlineStyleSingle]range:strRange];

[_phoneBtnsetAttributedTitle:strforState:UIControlStateNormal]
