UILabel用法大全

------------------------------------类方法获取UILabel----------------------------------------

///------------------------------- frame（no supView）适合自己写frame不用masnory---------------------------

+(UILabel *)getLabel:(CGRect)frame fontSize:(float)fontSize alignment:(NSTextAlignment)alignment textColor:(UIColor *)textColor{

    UILabel *label = [[UILabel alloc]init];

    label.frame = frame;

    label.font = [UIFont systemFontOfSize:16];//默认是16

    if (fontSize > 0) {

        label.font = [UIFont systemFontOfSize:fontSize];

    }

    label.textAlignment = alignment;

    

    label.textColor = textColor;

    label.backgroundColor = [UIColorclearColor];

    

    return label;

 

}

 

 

 

------------------------------------------自动换行-------------------------------------------------------

    label.numberOfLines = 0;//多行自动农行了。

[label sizeToFit];/// 左对齐可以。。这样就有label的宽度了。------宽高自动是文字的宽高了

// 右对齐的话，需要设置下frame

    label.frame = CGRectMake(kScreenWidth - label.width - 20, 100, label.width, 15);

 

 

-------------------------------------------行间距------------------------------------------------------------

 例子1：NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStylealloc] init];

    paragraphStyle.lineSpacing = 5.0f;

    UIFont *tempFont = [SJBFontpreferedFont:kPreferedFontTypebasicFont:kDefaultFontTypesize:14.0f];

    NSDictionary *tempDict = @{NSFontAttributeName:tempFont, NSKernAttributeName:[NSNumbernumberWithFloat:1.0f],NSParagraphStyleAttributeName:paragraphStyle};

    _contentLabel.attributedText = [[NSAttributedString alloc]initWithString:tempString attributes:tempDict];

 例子2：

NSString *tempS = [NSStringstringWithFormat:@"%@",[data objectForKey:@"summary"]];

        NSMutableAttributedString *attributedString = [[NSMutableAttributedStringalloc] initWithString:tempS];

        NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStylealloc] init];

        [paragraphStyle setLineSpacing:3.0f];//调整行间距

        [attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [tempS length])];

        _englishNameL.attributedText = attributedString;
