我正在尝试在以下位置获取所选字符的实际点NSTextContainer：

func handleTouch(gestureRecognizer: UIGestureRecognizer) {
   var location = gestureRecognizer.locationInView(self)
   let startPoint = self.layoutManager.locationForGlyphAtIndex(0)
   location = CGPoint(x: location.x - startPoint.x, y: location.y - startPoint.y)
   var fraction: CGFloat = 0
   let index = self.layoutManager.glyphIndexForPoint(location, inTextContainer: textContainer, fractionOfDistanceThroughGlyph: &fraction)
}

它可以正常工作，直到第一个换行符由 

NSParagraphStyle.hyphenationFactor = 2

每个连字符将索引移动一个点并glyphIndexForPoint得到错误的索引。如何在启用换行模式的情况下获得正确的索引？

尝试类似的功能characterIndexForPoint(_:inTextContainer:fractionOfDistanceBetweenInsertionPoints:)
