Setting custom rightView on TextField causes strange scroll behaviour

[RaoulNL]

Hi,

Awesome component!

Question though; I want to set a custom rightView on one of my TextFields, but when I do so the rightView also scrolls down when the custom errorMessage, displayed below the line, is animated.
Note: I use the component in a swift project using a bridging header.

My code to set the custom rightView:
let eyeButton = UIButton(type: .custom)
eyeButton.setImage(UIImage(named: "icon_eye"), for: .normal)
eyeButton.imageEdgeInsets = UIEdgeInsetsMake(0, -16, 0, 0)
eyeButton.frame = CGRect(x: CGFloat(passwordTextField.frame.size.width - 16), y:(passwordTextField.frame.size.height - 16) / 2, width: CGFloat(16), height: CGFloat(16))
eyeButton.addTarget(self, action: #selector(self.togglePassword), for: .touchUpInside)
passwordTextField.rightViewMode = UITextFieldViewMode.always
passwordTextField.rightView = eyeButton

The setup of the MFTextField itself it pretty straightforward, using properties like underlineColor, placeholderFont etc.
Can someone verify this behaviour?

Cheers, Raoul.

The issue I described can be solved with a small adjustment to the MFTextField.m file.
Here's the code:

- (CGRect)rightViewRectForBounds:(CGRect)bounds
{
CGRect rightViewRect = [super rightViewRectForBounds:bounds];
rightViewRect.origin.y = CGRectGetMidY(_textRect) - (rightViewRect.size.height / 2.0f);

return rightViewRect;
}

Obviously, this could also be applied to the leftView.
