光标的背景阴影在 Swift2 中的 Textfield 上发生变化

Question

Hello an unusual shadow is there where the cursor is placed please help me to remove it as seen at the screenshot .? thanks in advance

        // set the shadow of view
        loginView.backgroundColor = UIColor(red: 255.0/255.0, green: 255.0/255.0, blue: 255.0/255.0, alpha: 0.6)
        loginView.layer.shadowRadius = 10
        loginView.layer.shadowOffset = CGSizeMake(0, 0)
        loginView.layer.shadowColor = UIColor.blackColor().CGColor
        loginView.clipsToBounds = false
        self.loginView.layer.shadowOpacity = 0.3;

        loginView.layer.cornerRadius = 10
        loginView.layer.masksToBounds = true

here i set the delegate the of textfield

countryNameText.delegate = self
        countryNameText.tag = 1
        mobileNumberText.delegate = self
        mobileNumberText.tag = 2

this code is used to set gradient colour of view

func gradient() {
        let gradient: CAGradientLayer = CAGradientLayer()
        gradient.frame = self.view.bounds
        gradient.colors = [UIColor(red: 26.0/255.0, green: 159.0/255.0, blue: 154.0/255.0, alpha: 0.2).CGColor,  UIColor(red: 26.0/255.0, green: 159.0/255.0, blue: 154.0/255.0, alpha: 0.5).CGColor , UIColor(red: 26.0/255.0, green: 159.0/255.0, blue: 154.0/255.0, alpha: 0.9).CGColor ]
        gradient.startPoint = CGPoint(x: 0, y: 0)
        gradient.endPoint = CGPoint(x: 1, y: 1)
        self.view.layer.insertSublayer(gradient, atIndex: 0)
    }
