+追記:
+ご指摘のあったCustomLabelClass.swiftの内容を載せてみました。
+内容は、個々でラベルのコーナーをラウンドさせるための処理になります。
+```swift
+class CustomLabelClass: UILabel {
+    var corners: UIRectCorner = [.TopLeft, .TopRight, .BottomLeft, .BottomRight]
+    var radius: CGFloat = 0
+    var padding: UIEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
+    func setPadding(pt:CGFloat, pr:CGFloat, pb:CGFloat, pl:CGFloat) {
+        self.padding = UIEdgeInsets(top: pt, left: pl, bottom: pb, right: pr)
+    }
+    override func drawTextInRect(rect: CGRect) {
+        let newRect = UIEdgeInsetsInsetRect(rect, padding)
+        super.drawTextInRect(newRect)
+    }
+    override func intrinsicContentSize() -> CGSize {
+        var intrinsicContentSize = super.intrinsicContentSize()
+        intrinsicContentSize.height += padding.top + padding.bottom
+        intrinsicContentSize.width  += padding.left + padding.right
+        return intrinsicContentSize
+    }
+    func setCornersAndRadius(corners:UIRectCorner, radius: CGFloat) {
+        self.corners = corners
+        self.radius = radius
+    }
+    override func layoutSubviews() {
+        super.layoutSubviews()
+        let maskPath = UIBezierPath(roundedRect: self.bounds,
+                                    byRoundingCorners: self.corners,
+                                    cornerRadii: CGSize(width: self.radius, height: self.radius))
