UILabel

extension UILabel: SkeletonViewDataSource

UILabel骨架屏视图数据源扩展

UILabel+UIKit

  • 快速设置attributedText样式，设置后调用setText:会自动转发到setAttributedText:方法

    Declaration

    Swift

    public var fw_textAttributes: [NSAttributedString.Key : Any]? { get set }

  • 快速设置文字的行高，优先级低于fwTextAttributes，设置后调用setText:会自动转发到setAttributedText:方法。小于等于0时恢复默认行高

    Declaration

    Swift

    public var fw_lineHeight: CGFloat { get set }

  • 自定义内容边距，未设置时为系统默认。当内容为空时不参与intrinsicContentSize和sizeThatFits:计算，方便自动布局

    Declaration

    Swift

    public var fw_contentInset: UIEdgeInsets { get set }

  • 纵向分布方式，默认居中

    Declaration

    Swift

    public var fw_verticalAlignment: UIControl.ContentVerticalAlignment { get set }

  • 添加点击手势并自动识别NSLinkAttributeName|URL属性，点击高亮时回调链接，点击其它区域回调nil

    Declaration

    Swift

    public func fw_addLinkGesture(block: @escaping (Any?) -> Void)

  • 获取手势触发位置的文本属性，可实现行内点击效果等，allowsSpacing默认为NO空白处不可点击。为了识别更准确，attributedText需指定font

    Declaration

    Swift

    public func fw_attributes(
    gesture: UIGestureRecognizer,
    allowsSpacing: Bool
) -> [NSAttributedString.Key: Any]

  • 快速设置标签并指定文本

    Declaration

    Swift

    public func fw_setFont(
    _ font: UIFont?,
    textColor: UIColor?,
    text: String? = nil,
    textAlignment: NSTextAlignment? = nil,
    numberOfLines: Int? = nil,
    lineHeight: CGFloat? = nil
)

  • 快速创建标签并指定文本

    Declaration

    Swift

    public static func fw_label(
    font: UIFont?,
    textColor: UIColor?,
    text: String? = nil,
    textAlignment: NSTextAlignment? = nil,
    numberOfLines: Int? = nil,
    lineHeight: CGFloat? = nil
) -> Self

  • 自适应字体大小，可设置缩放因子等

    Declaration

    Swift

    public func fw_adjustsFontSize(
    minimumScaleFactor: CGFloat? = nil,
    baselineAdjustment: UIBaselineAdjustment? = nil
)

  • 获取当前标签是否非空，兼容attributedText|text

    Declaration

    Swift

    public var fw_isNotEmpty: Bool { get }

  • 计算当前标签实际显示行数，兼容contentInset|lineHeight

    Declaration

    Swift

    public var fw_actualNumberOfLines: Int { get }

  • 计算指定边界、内边距、行高、行数时，当前标签实际显示行数

    Declaration

    Swift

    public func fw_actualNumberOfLines(drawSize: CGSize, contentInset: UIEdgeInsets? = nil, lineHeight: CGFloat? = nil, numberOfLines: Int? = nil) -> Int

  • 计算当前文本所占尺寸，需frame或者宽度布局完整

    Declaration

    Swift

    public var fw_textSize: CGSize { get }

  • 计算指定边界时，当前文本所占尺寸

    Declaration

    Swift

    public func fw_textSize(drawSize: CGSize, contentInset: UIEdgeInsets? = nil) -> CGSize

  • 计算当前属性文本所占尺寸，需frame或者宽度布局完整，attributedText需指定字体

    Declaration

    Swift

    public var fw_attributedTextSize: CGSize { get }

  • 计算指定边界时，当前属性文本所占尺寸，attributedText需指定字体

    Declaration

    Swift

    public func fw_attributedTextSize(drawSize: CGSize, contentInset: UIEdgeInsets? = nil) -> CGSize
