SwiftyAttributes

归因字符串的swifty API。

---

使用SwiftyAttributes ，您可以创建类似的属性字符串：

 let fancyString = " Hello World! " . withTextColor ( . blue ) . withUnderlineStyle ( . styleSingle )

或者，使用Attribute枚举：

 let fancyString = " Hello World! " . withAttributes ( [
    . backgroundColor ( . magenta ) ,
    . strokeColor ( . orange ) ,
    . strokeWidth ( 1 ) ,
    . baselineOffset ( 5.2 )
] )

您还可以使用加号轻松将属性字符串组合在一起：

 let fancyString = " Hello " . withFont ( . systemFont ( ofSize : 12 ) ) + " World! " . withFont ( . systemFont ( ofSize : 18 ) )

SwiftyAttributes可以支持可可和可可触摸中可用的每个属性。

用法

在SwiftyAttributes中初始化归因的字符串可以做几种方法：

• 使用with[Attribute]扩展：

   " Hello World " . withUnderlineColor ( . red ) . withUnderlineStyle ( . styleDouble )

• 使用Attribute枚举扩展：

   " Hello World " . withAttributes ( [ . underlineColor ( . red ) , . underlineStyle ( . styleDouble ) ] )

• 使用初始化器中的Attribute枚举：

   NSAttributedString ( string : " Hello World " , swiftyAttributes : [ . kern ( 5 ) , . backgroundColor ( . gray ) ] )

您可以使用内置的NSAttributedString.Key Enum：

 let attr : Attribute ? = myAttributedString . swiftyAttribute ( . shadow , at : 5 )

提供了几种使用这些新枚举以及Swift Range类型而不是NSRange的API方法。一些方法签名包括：

 extension NSMutableAttributedString {
    func addAttributes ( _ attributes : [ Attribute ] , range : Range < Int > )
    func addAttributes ( _ attributes : [ Attribute ] , range : NSRange )
    func setAttributes ( _ attributes : [ Attribute ] , range : Range < Int > )
    func setAttributes ( _ attributes : [ Attribute ] , range : NSRange )
    func replaceCharacters ( in range : Range < Int > , with str : String )
    func replaceCharacters ( in range : Range < Int > , with attrString : NSAttributedString )
    func deleteCharacters ( in range : Range < Int > )
    func removeAttribute ( _ name : NSAttributedStringKey , range : Range < Int > )
}

extension NSAttributedString {
    convenience init ( string str : String , swiftyAttributes : [ Attribute ] )
    func withAttributes ( _ attributes : [ Attribute ] ) -> NSMutableAttributedString
    func withAttribute ( _ attribute : Attribute ) -> NSMutableAttributedString
    func attributedSubstring ( from range : Range < Int > ) -> NSAttributedString
    func swiftyAttribute ( _ attrName : NSAttributedStringKey , at location : Int , effectiveRange range : NSRangePointer ? = nil ) -> Attribute ?
    func swiftyAttributes ( in range : Range < Int > , options : NSAttributedString . EnumerationOptions = [ ] ) -> [ ( [ Attribute ] , Range < Int > ) ]
    func enum erateSwiftyAttributes ( in enum erationRange : Range < Int > , options : NSAttributedString . EnumerationOptions = [ ] , using block : ( _ attrs : [ Attribute ] , _ range : Range < Int > , _ stop : UnsafeMutablePointer < ObjCBool > ) -> Void )
    func enum erateSwiftyAttribute ( _ attrName : NSAttributedStringKey , in enum erationRange : Range < Int > , options : NSAttributedString . EnumerationOptions = [ ] , using block : ( _ value : Any ? , _ range : Range < Int > , _ stop : UnsafeMutablePointer < ObjCBool > ) -> Void )
}

extension String {
    var attributedString : NSMutableAttributedString
    func withAttributes ( _ attributes : [ Attribute ] ) -> NSMutableAttributedString
    func withAttribute ( _ attribute : Attribute ) -> NSMutableAttributedString
}
