ios - 如何在 swift 3 开始编辑时为多个 uitextfield 设置边框颜色？

Question

我有 3 个 uitextfields 并且我还编写了用于在开始编辑时设置 uitextfields 边框颜色的代码，但是当我单击一个 uitextfields 时所有其他两个 textfields 边框也变成橙色。

需要一些帮助

var colorBorder = UIColor(netHex:0xdb8925)
self.uitextfieldAmount.delegate = self
self.uitextfieldBeneficiaryID.delegate = self
self.uitextfieldNote.delegate = self

 func textFieldDidBeginEditing(textField: UITextField) {
    uitextfieldBeneficiaryID.layer.borderColor = colorBorder.CGColor
    //uitextfieldAmount.layer.borderColor = colorBorder.CGColor
    //uitextfieldNote.layer.borderColor = colorBorder.CGColor
}

var colorBorder = UIColor(netHex:0xdb8925)
self.uitextfieldAmount.delegate = self
self.uitextfieldBeneficiaryID.delegate = self
self.uitextfieldNote.delegate = self

func textFieldDidBeginEditing(textField: UITextField) {
    if textField == uitextfieldBeneficiaryID {
        uitextfieldBeneficiaryID.layer.borderColor = // Color you want
    } else if textField == uitextfieldAmount {
        uitextfieldAmount.layer.borderColor = // Color you want
    } else {
        uitextfieldNote.layer.borderColor = // Color you want
    }
}

这样试试。谢谢:)
