就是简单的做个笔记哈。
一 文本属性
NSFontAttributeName //设置字体大小
NSParagraphStyleAttributeName //设置段落格式
NSForegroundColorAttributeName //设置字体的颜色
NSBackgroundColorAttributeName //设置背景的颜色
NSLigatureAttributeName //设置连体字符
NSKernAttributeName //设置文字之间的距离
NSStrikethroughStyleAttributeName //设置删除线的样式
NSUnderlineStyleAttributeName //设置下划线的格式
NSStrikethroughColorAttributeName //设置删除线的颜色
NSStrokeColorAttributeName //设置中空效果的填充颜色
NSStrokeWidthAttributeName //设置中空效果的宽度
NSShadowAttributeName //设置阴影效果
NSTextEffectAttributeName //设置文本的特殊效果
NSAttachmentAttributeName //设置文本附件
NSLinkAttributeName //设置超链接
NSBaselineOffsetAttributeName //设置基线偏移值
NSUnderlineColorAttributeName //设置下划线的颜色
NSObliquenessAttributeName //设置字体倾斜
NSExpansionAttributeName //设置文本扁平化(横向拉伸)
NSWritingDirectionAttributeName //设置文字的书写方向
NSVerticalGlyphFormAttributeName //设置文字的排版方向
二 使用示例
书写方式
//有范围
NSString * helloStr = @"hello word";
NSMutableAttributedString * mString = [[NSMutableAttributedString alloc] initWithString: helloStr];
//方式1
NSDictionary * dic = @{NSFontAttributeName :[UIFont fontWithName:@"Helvetica-Bold" size:20],NSForegroundColorAttributeName:[UIColor redColor],};
[mString addAttributes:dic range:NSMakeRange(0, 3)];
//方式2
[mString addAttribute: NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, 4)];
[mString addAttribute: NSFontAttributeName value:[UIFont fontWithName:@"Helvetica-Bold" size:20] range:NSMakeRange(0, 7)];
label.attributedText = mString;
//无范围
label.attributedText = [[NSAttributedString alloc]initWithString: helloStr attributes:dic];
字体段落
NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc]init];
style.alignment = NSTextAlignmentLeft;
style.lineSpacing = 5;
//指定段落开始的缩进像素
style.firstLineHeadIndent = 20;
//调整全部文字的缩进像素
style.headIndent = 2;
[mString addAttribute:NSParagraphStyleAttributeName value:style range:NSMakeRange(0, str.length)];
//字间距
[mString addAttribute:NSKernAttributeName value:@1.5 range:NSMakeRange(0, str.length)];
//NSDictionary * dic = @{NSFontAttributeName :[UIFont fontWithName:@"Helvetica-Bold" size:20],NSForegroundColorAttributeName:[UIColor redColor],NSParagraphStyleAttributeName:style,NSKernAttributeName:@1.5f,};
字体相关
//调整字间距:
[mString addAttribute:NSKernAttributeName value:@10 range:range];
//设置字体:
[mString addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:22] range:range];
//设置文本颜色:
[mString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:range];
//设置文本背景色:
[mString addAttribute:NSBackgroundColorAttributeName value:[UIColor greenColor] range:range];
//描边颜色 NSStrokeWidthAttributeName 正值 字体空心 负值 字体 非空心 会使NSForegroundColorAttributeName 无效果
[mString addAttribute:NSStrokeColorAttributeName value:[UIColor greenColor] range:range];
[mString addAttribute:NSStrokeWidthAttributeName value:@3 range:range];
//删除线
[mString addAttribute:NSStrikethroughStyleAttributeName value:@(NSUnderlineStyleSingle) range:range];
//下划线
[mString addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleSingle) range:range];
//设置阴影
NSShadow *shadow = [[NSShadow alloc]init];
shadow.shadowBlurRadius = 5;//设置模糊度
shadow.shadowColor = [UIColor blueColor];//设置阴影颜色
shadow.shadowOffset = CGSizeMake(1, 3);//设置阴影的偏移量
[mString addAttribute:NSShadowAttributeName value:shadow range:range];
//文本排版方式
[mString addAttribute:NSVerticalGlyphFormAttributeName value:@(0) range:range];
//文本斜体
[mString addAttribute:NSObliquenessAttributeName value:@(1) range:range];
//扁平化
[mString addAttribute:NSExpansionAttributeName value:@(1) range:range];
