在動畫背景顏色的同時選擇UITextField

Question

如何爲TextField設置動畫而不禁用它？

UIView.animate(withDuration: 1.0, delay: 0.0, options: [.repeat, .autoreverse, .curveEaseInOut], animations: { 
        (self.phoneCell.subviews[1].subviews[1] as! UITextField).layer.backgroundColor = UIColor.black.withAlphaComponent(0.2).cgColor 
       }, completion: nil)

爲了讓動畫過程中的用戶交互爲您UITextField，你需要添加選項.allowUserInteraction：

UIView.animate(withDuration: 1.0, delay: 0.0, 
    options: [.repeat, .autoreverse, .curveEaseInOut, .allowUserInteraction], 
    animations: { 
     self.myTextField.layer.backgroundColor = UIColor.black.withAlphaComponent(0.2).cgColor 
    }, completion: nil)
