NSAttributedString(FWFoundation)

@interface NSAttributedString (FWFoundation)

如果需要实现行内图片可点击效果，可使用UITextView添加附件或Link并实现delegate.shouldInteractWith方法即可

  • NSAttributedString对象转换为html字符串

    Declaration

    Objective-C

    - (nullable NSString *)fw_htmlString;

  • 计算所占尺寸，需设置Font等

    Declaration

    Objective-C

    @property (nonatomic, readonly) CGSize fw_textSize;

  • 计算在指定绘制区域内所占尺寸，需设置Font等

    Declaration

    Objective-C

    - (CGSize)fw_textSizeWithDrawSize:(CGSize)drawSize;

  • html字符串转换为NSAttributedString对象。如需设置默认字体和颜色，请使用addAttributes方法或附加CSS样式

    Declaration

    Objective-C

    + (nullable instancetype)fw_attributedStringWithHtmlString:
    (nonnull NSString *)htmlString;

  • 图片转换为NSAttributedString对象，可实现行内图片样式。其中bounds.x会设置为间距，y常用算法：(font.capHeight - image.size.height) / 2.0

    Declaration

    Objective-C

    + (nonnull NSAttributedString *)fw_attributedStringWithImage:
                                    (nullable UIImage *)image
                                                      bounds:(CGRect)bounds;

  • 快速创建NSAttributedString，自定义字体

    Declaration

    Objective-C

    + (nonnull instancetype)fw_attributedString:(nonnull NSString *)string
                                   withFont:(nullable UIFont *)font;

  • 快速创建NSAttributedString，自定义字体和颜色

    Declaration

    Objective-C

    + (nonnull instancetype)fw_attributedString:(nonnull NSString *)string
                                   withFont:(nullable UIFont *)font
                                  textColor:(nullable UIColor *)textColor;
