以下のクラスと関数を使用して非表示の文字を表示しようとしていますが、正常に動作しています。

しかし、replaceGlyphAtIndex は OS X 10.11 で廃止され、setGlyhs() を使用する必要があります。

setGlyphs(<#T##glyphs: UnsafePointer<CGGlyph>##UnsafePointer<CGGlyph>#>, properties: <#T##UnsafePointer<NSGlyphProperty>#>, characterIndexes: <#T##UnsafePointer<Int>#>, font: <#T##NSFont#>, forGlyphRange: <#T##NSRange#>)

しかし、replaceGlyphAtIndex を setGlyphs に変換する方法に問題があります。replaceGlyphAtIndex の下を setGlyphs() に変換する方法を教えてもらえますか?

私は以下のように試しましたが、クラッシュしています。

let data = String(g).dataUsingEncoding(NSUTF8StringEncoding)
let cgG = UnsafePointer<CGGlyph>(data!.bytes)
self.setGlyphs(cgG, properties: nil, characterIndexes: UnsafePointer<Int>(bitPattern: characterIndex), font: font as! NSFont, forGlyphRange: NSMakeRange(glyphIndex, 1))

上記のコード行で何が問題になっているのか、誰か教えてもらえますか?

class MyLayoutManager: NSLayoutManager {

override func drawGlyphsForGlyphRange(glyphsToShow: NSRange, atPoint origin: NSPoint) {
    if let storage = self.textStorage {
        let s = storage.string
        let startIndex = s.startIndex

        for glyphIndex in glyphsToShow.location ..< glyphsToShow.location + glyphsToShow.length {
            let characterIndex = self.characterIndexForGlyphAtIndex(glyphIndex)
            let ch = s[startIndex.advancedBy(characterIndex)]
            switch ch {
            case " ": //Blank Space
                let attrs = storage.attributesAtIndex(characterIndex, effectiveRange: nil)
                if let font = attrs[NSFontAttributeName] {
                    let g = font.glyphWithName("period")//("periodcentered")
                    self.replaceGlyphAtIndex(glyphIndex, withGlyph: g)


                    //                        let data = String(g).dataUsingEncoding(NSUTF8StringEncoding)
                    //                        let cgG = UnsafePointer<CGGlyph>(data!.bytes)
                    //
                    //                        self.setGlyphs(cgG, properties: nil, characterIndexes: UnsafePointer<Int>(bitPattern: characterIndex), font: font as! NSFont, forGlyphRange: NSMakeRange(glyphIndex, 1))
                }
            case "\n": //New Line
                let attrs = storage.attributesAtIndex(characterIndex, effectiveRange: nil)
                if let font = attrs[NSFontAttributeName] {
                    let g = font.glyphWithName("logicalnot")
                    self.replaceGlyphAtIndex(glyphIndex, withGlyph: g)
                }
            case newLineUniCodeStr:
                let attrs = storage.attributesAtIndex(characterIndex, effectiveRange: nil)
                if let font = attrs[NSFontAttributeName] {
                    let g = font.glyphWithName("logicalnot")
                    self.replaceGlyphAtIndex(glyphIndex, withGlyph: g)
                }
            default:
                break
            }
        }
    }
    super.drawGlyphsForGlyphRange(glyphsToShow, atPoint: origin)
}

}

グリフを表示する別の方法を見つけました。（他の人に役立つかもしれないので、私のコードを以下に投稿してください）

override func drawGlyphsForGlyphRange(glyphsToShow: NSRange, atPoint origin: NSPoint) {
    if let storage = self.textStorage {
        let s = storage.string
        let startIndex = s.startIndex

        var padding:CGFloat = 0
        for glyphIndex in glyphsToShow.location ..< glyphsToShow.location + glyphsToShow.length {
            let characterIndex = self.characterIndexForGlyphAtIndex(glyphIndex)
            if characterIndex < s.characters.count
            {
                var glyphStr = ""
                let ch = s[startIndex.advancedBy(characterIndex)]
                switch ch {
                case " ": //Blank Space
                    glyphStr = periodCenteredUniCodeStr
                case "\n": //New Line
                    glyphStr = lineBreakUniCodeStr
                case newLineUniCodeStr:
                    glyphStr = lineBreakUniCodeStr
                    padding += 5
                default:
                    break
                }
                var glyphPoint = self.locationForGlyphAtIndex(glyphIndex)
                let glyphRect = self.lineFragmentRectForGlyphAtIndex(glyphIndex, effectiveRange: nil)
                if glyphStr.characters.count > 0{
                    glyphPoint.x = glyphPoint.x + glyphRect.origin.x
                    glyphPoint.y = glyphRect.origin.y
                    NSString(string: glyphStr).drawInRect(NSMakeRect(glyphPoint.x, glyphPoint.y, 10, 10), withAttributes: nil)
                }
            }else{
                print("Wrong count here")
            }
        }

    }
    super.drawGlyphsForGlyphRange(glyphsToShow, atPoint: origin)
}
