在UIProgressView栏的末尾添加标签

Question

借助UIProgressBar中UITableView的帮助，我可以通过per获得水平条形图的视图，

当前输出

//TEST DATA:
arrShareNames = ["Infosys","TCS","Reliance","Wipro"]
arrSharepercent = [30,40,21,10]

if let progressView = self.view.viewWithTag(101) as? UIProgressView {
    progressView.progress = 0.0
    progressView.progress =  Float(arrSharepercent[indexPath.row]/100)
    progressView.progressViewStyle = UIProgressViewStyle.bar
    progressView.transform = CGAffineTransform(rotationAngle: CGFloat(-Double.pi));
}

我要在图表的每个条形旁边添加百分比值，如下所示：

所需的输出

我们如何在进度条的末尾添加进度百分比标签？
