//1.简单显示label

label.lineBreakMode=0

label.numberOfLines = NSLineBreakByWordWrapping

label.text=@"YYTextDemo Test"

//    [self.view addSubview:label]

//2.属性字符串 简单实用

NSMutableAttributedString*text= [[NSMutableAttributedStringalloc] initWithString:@"上海市第九城市信息技术有限公司"]

text.font = [UIFontboldSystemFontOfSize:13.0f]

text.color = [UIColorblueColor]

[textsetColor:[UIColor redColor]range:NSMakeRange(0,4)]

//    给你的label添加点击事件

[textsetTextHighlightRange:NSMakeRange(0,4)
