UILabel、UIBUtton等的 text的样式

UILabel *lab = [[UILabelalloc] initWithFrame:CGRectMake(10,100, 300, 100)];

lab.numberOfLines =4;

[self.viewaddSubview:lab];

//删除、替换、插入

NSMutableAttributedString *attStr = [[NSMutableAttributedStringalloc] initWithString:@"你好吗，我很好。你好吗，我很好。你好吗，我很好。你好吗，我很好。你好吗，我很好。你好吗，我很好。你好吗，我很好。我很好。"];

// 添加删除线

[attStr addAttribute:NSStrikethroughStyleAttributeNamevalue:[NSNumbernumberWithInt:NSUnderlineStyleSingle]range:NSMakeRange(0,3)];

// 添加下划线

[attStr addAttribute:NSUnderlineStyleAttributeNamevalue:[NSNumbernumberWithInt:NSUnderlineStyleSingle]range:NSMakeRange(4,3)];

// 某个字体大小

[attStr addAttribute:NSFontAttributeNamevalue:[UIFontsystemFontOfSize:22]range:NSMakeRange(8,3)];

// 字体颜色

[attStr addAttribute:NSForegroundColorAttributeNamevalue:[UIColorredColor] range:NSMakeRange(12,3)];

// 设置笔画的粗细

[attStr addAttribute:NSStrokeWidthAttributeNamevalue:[NSNumbernumberWithInt:NSUnderlineStyleDouble]range:NSMakeRange(16,3)];

// label 的背景颜色

[attStr addAttribute:NSBackgroundColorAttributeNamevalue:[UIColorgreenColor] range:NSMakeRange(20,3)];

// label上文本颜色（也会影响删除线和下划线的颜色）

[attStr addAttribute:NSForegroundColorAttributeNamevalue:[UIColorblueColor] range:NSMakeRange(24,3)];

[attStr addAttribute:NSStrikethroughStyleAttributeNamevalue:[NSNumbernumberWithInt:NSUnderlineStyleSingle]range:NSMakeRange(24,3)];

[attStr addAttribute:NSUnderlineStyleAttributeNamevalue:[NSNumbernumberWithInt:NSUnderlineStyleSingle]range:NSMakeRange(24,3)];

//文本内容颜色和删除线、下划线颜色不一样

// NSStrokeColorAttributeName 单独设置没有效果

// 必须与NSStrokeWidthAttributeName一起设置

[attStr addAttribute:NSForegroundColorAttributeNamevalue:[UIColorblueColor] range:NSMakeRange(28,3)];

[attStr addAttribute:NSStrikethroughStyleAttributeNamevalue:[NSNumbernumberWithInt:NSUnderlineStyleSingle]range:NSMakeRange(28,3)];

[attStr addAttribute:NSStrokeColorAttributeNamevalue:[UIColorredColor] range:NSMakeRange(28,3)]; //cyanColor

[attStr addAttribute:NSStrokeWidthAttributeNamevalue:[NSNumbernumberWithInt:NSUnderlineStyleSingle]range:NSMakeRange(28,3)];

// 笔画的阴影效果

NSShadow *shadow = [[NSShadowalloc] init];

[shadow setShadowColor:[UIColorredColor]];

[shadow setShadowBlurRadius:4];

[shadow setShadowOffset:CGSizeMake(2,2)];

[attStr addAttribute:NSShadowAttributeNamevalue:shadow range:NSMakeRange(32,3)];

[attStr addAttribute:NSParagraphStyleAttributeNamevalue:[NSNumbernumberWithInt:NSUnderlineStyleSingle]range:NSMakeRange(36,3)];

//[attStr addAttribute:NSVerticalGlyphFormAttributeName value:[NSNumber numberWithInt:1] range:NSMakeRange(28, 4)];

lab.attributedText = attStr;
