label5.numberOfLines = 2;//设置label的行数

其他:
label.transform = CGAffineTransformMakeRotation(0.2);//设置label的旋转角度
label7.userInteractionEnabled = YES; //设置是否能与用户进行交互
label3.enabled = NO;//设置label中的文字是否可变,默认值是YES
label3.lineBreakMode = UILineBreakModeMiddleTruncation;//截去中间 //设置文字过长时的显示格式
// UILineBreakModeWordWrap = 0,
// UILineBreakModeCharacterWrap,
// UILineBreakModeClip,//截去多余部分
// UILineBreakModeHeadTruncation,//截去头部
// UILineBreakModeTailTruncation,//截去尾部
// UILineBreakModeMiddleTruncation,//截去中间
