AttributeText创建多彩文字Label --- hl

一般用富文本实现多种花样的Label文字,下图是利用UILabel分类快速创建的多彩多样lable文字,快速简单,自定义性强,更重要的是无代码污染,特别适合轻量级使用

https://github.com/joaoffcosta/UILabel-FormattedText

在我写这篇博客的第二天,作者就把代码全部改成swift了....

 

 

主要功能介绍:

在同一lablel中设置不同文字字体,文字颜色,下划线,删除线,字间距,斜体,图片

在类别中新加几个个方法,这样更加强大,方便使用,其它方法调用详见Demo

//  UILabel+FormattedText.h

 

#pragma mark--自定义添加
/*设置字体于颜色*/
- (void) setFont:(UIFont *)font substring:(NSString*)substring;
- (void) setFont:(UIFont *)font WithtColor:(UIColor *)textColor  substring:(NSString*)substring;

/**添加删除线 */
-(void)setTextDeleteLine:(UIColor *)lineColor range:(NSRange)range;

/**斜体*/
-(void)setObliqueness:(id)obliqueness range:(NSRange)range;

/** 字间距 */
-(void)setWordSpace:(id)space range:(NSRange)range;

/** 添加多个属性*/
-(void)setTextAttributes:(NSDictionary *)attributes range:(NSRange)range;

/*添加图片*/
-(void)addImgAttachment:(UIImage *)image size:(CGSize)size range:(NSRange)range;

使用

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.view.backgroundColor=[UIColor blackColor];
    
    NSString *text=@"思埠集团于2015年1月6日正式入股本土第一家在新三板上市日化企业——幸美股份(代码830929),成为幸美最大股东。广东思埠集团直接控股新三板挂牌上市公司幸美股份,正式成为准上市公司。";

    // Colors AND Fonts
    UILabel *labelCF = [[UILabel alloc] init];
    [labelCF setFrame:CGRectMake(0, floorf(self.view.frame.size.height * 2 / 4), self.view.frame.size.width, floorf(self.view.frame.size.height / 3))];
    [labelCF setBackgroundColor:[UIColor clearColor]];
    [labelCF setTextAlignment:NSTextAlignmentCenter];
    [labelCF setText:text];
