Experimental code from MemeMe app and former drawTextInRect method.

iOS Swift Programmatic UITextFields

        topTextField.frame = CGRect(x: rect.origin.x, y: rect.origin.y + 500, width: 500, height: 100)
        topTextField.backgroundColor = UIColor.blueColor()
        self.imageView.addSubview(topTextField)
        
        // I just wasn't changing it enough, 10 pts is really small, apparently
        var y: CGFloat = (rect.origin.y - 50.0)
        
        // TEST - DOES THIS EVEN PUT A THING ANYWHERE (the answer was no, bc of autolayout and constraints)
        var testTopTextField: UITextField = UITextField(frame: CGRect(x: rect.origin.x + 10, y: y, width: 300.0, height: 50.0))
        testTopTextField.text = "KITTENS"
        testTopTextField.backgroundColor = UIColor.greenColor()
        self.imageView.addSubview(testTopTextField)
        
        var testBottomTextField: UITextField = UITextField(frame: CGRect(x: rect.origin.x, y: rect.origin.y + (rect.size.height / 2), width: 300.0, height: 50.0))
        testBottomTextField.text = "R SO CEWT"
        testBottomTextField.backgroundColor = UIColor.purpleColor()
        self.imageView.addSubview(testBottomTextField)
