UILabel vertical alignment

Question

In my application i am using ActiveLabelfram Github.

In that case, my label does not show the text in the middle of the UILabel. If i use a normal UILabel it works fine, but when settings it to a ActiveLabel, it gets like this.

(Image is taken in runtime)

I think this is the code to play with the alignment somehow:

/// add line break mode
private func addLineBreak(attrString: NSAttributedString) -> NSMutableAttributedString {
    let mutAttrString = NSMutableAttributedString(attributedString: attrString)

    var range = NSRange(location: 0, length: 0)
    var attributes = mutAttrString.attributesAtIndex(0, effectiveRange: &range)

    let paragraphStyle = attributes[NSParagraphStyleAttributeName] as? NSMutableParagraphStyle ?? NSMutableParagraphStyle()
    paragraphStyle.lineBreakMode = NSLineBreakMode.ByWordWrapping
    if let lineSpacing = lineSpacing {
        paragraphStyle.lineSpacing = CGFloat(lineSpacing)
    }

    attributes[NSParagraphStyleAttributeName] = paragraphStyle
    mutAttrString.setAttributes(attributes, range: range)

    return mutAttrString
}

ActiveLabel.swift

ActiveType.swift

Any ideas how i can make it in the middle like this:

In ActiveLabel.swift replace the drawTextInRect method with

public override func drawTextInRect(rect: CGRect) {
        let range = NSRange(location: 0, length: textStorage.length)

        textContainer.size = rect.size

        let usedRect = layoutManager.usedRectForTextContainer(textContainer)

        let glyphOriginY = (rect.height > usedRect.height) ? rect.origin.y + (rect.height - usedRect.height) / 2 : rect.origin.y
        let glyphOrigin = CGPointMake(rect.origin.x, glyphOriginY)

        layoutManager.drawBackgroundForGlyphRange(range, atPoint: glyphOrigin)
        layoutManager.drawGlyphsForGlyphRange(range, atPoint: glyphOrigin)
    }

I have also forked the repo under https://github.com/rishi420/ActiveLabel.swift

If you download the repo, remember to set verticalTextAlignmentCenter to true
