Swiftyattributes

API Swifty untuk string yang dikaitkan.

Dengan Swiftyattributes , Anda dapat membuat string yang dikaitkan seperti SO:

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

Atau, gunakan Attribute enum:

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

Anda juga dapat dengan mudah menggabungkan string yang dikaitkan menggunakan tanda plus:

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

Swiftyattributes memiliki dukungan untuk setiap atribut yang tersedia dalam Cocoa dan Cocoa Touch.

Penggunaan

Menginisialisasi string yang dikaitkan di SwiftyAttributes dapat dilakukan beberapa cara:

Menggunakan ekstensi with[Attribute] :

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

Menggunakan Ekstensi Enum Attribute :

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

Menggunakan Attribute ENUM di Initializer:

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

Anda dapat mengambil atribut di lokasi tertentu menggunakan NSAttributedString.Key enum built-in:

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

Beberapa metode API disediakan untuk menggunakan enum baru ini serta jenis Range Swift, bukan NSRange . Beberapa tanda tangan metode meliputi:

 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
}
