不哔哔，上代码：
extension UITextField {
func setupShowPasswordButton() {
let eyesButton = UIButton(type: .System)
eyesButton.frame = CGRect(x: 0, y: 0, w: 16, h: 16)
eyesButton.setImage(UIImage(named: "imgEyes"), forState: .Normal)
eyesButton.tintColor = UIColor.blue4Color
eyesButton.rx_tap.subscribeNext { [unowned self] in
self.secureTextEntry = !self.secureTextEntry
eyesButton.tintColor = self.secureTextEntry ? UIColor.blue4Color : UIColor.blue6Color
if self.isFirstResponder() { self.becomeFirstResponder() }
}.addDisposableTo(disposeBag)
rightView = eyesButton
rightViewMode = .Always
}
func setupClearButton() {
let clearButton = UIButton(type: .System)
clearButton.frame = CGRect(x: 0, y: 0, w: 16, h: 16)
clearButton.setImage(UIImage.imageWithIconFont(.CloseHL, iconColor: UIColor.blue4Color, fontSize: 24), forState: .Normal)
clearButton.rx_tap.subscribeNext { [unowned self] in
self.text = nil
}.addDisposableTo(disposeBag)
rightView = clearButton
rightViewMode = .WhileEditing
}
}
