单击键盘中的 Return 键时 UITextField 如何移动到下一个 TextField

Question

我正在使用这段代码来移动 UITextField，它正在工作，但我对这段代码不满意，我想要（当我单击 return 键然后光标移动到下一个 UITextField 时）这个功能在我的注册中或任何人都可以建议我的登录表格。

func textFieldDidBeginEditing(_ textField: UITextField) {
    switch textField {
    case txtFldSponsorID:
        moveTextfield(textfield: txtFldSponsorID, moveDistance: 0, up: true)
    case txtFldFullName:
        moveTextfield(textfield: txtFldFullName, moveDistance: -10, up: true)
    case txtFldEmail:
        moveTextfield(textfield: txtFldEmail, moveDistance: -10, up: true)
    case txtFldMobile:
        moveTextfield(textfield: txtFldMobile, moveDistance: -10, up: true)
    case txtFldAddress:
        moveTextfield(textfield: txtFldAddress, moveDistance: -80, up: true)
    case txtFldCity:
        moveTextfield(textfield: txtFldCity, moveDistance: -80, up: true)
    default:
        break
    }
}

func textFieldDidEndEditing(_ textField: UITextField) {
    switch textField {
    case txtFldSponsorID:
        moveTextfield(textfield: txtFldSponsorID, moveDistance: 0, up: true)
    case txtFldFullName:
        moveTextfield(textfield: txtFldFullName, moveDistance: 10, up: true)
    case txtFldEmail:
        moveTextfield(textfield: txtFldEmail, moveDistance: 10, up: true)
    case txtFldMobile:
        moveTextfield(textfield: txtFldMobile, moveDistance: 10, up: true)
    case txtFldAddress:
        moveTextfield(textfield: txtFldAddress, moveDistance: 80, up: true)
    case txtFldCity:
        moveTextfield(textfield: txtFldCity, moveDistance: 80, up: true)
    default:
        break
    }
}

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    textField.resignFirstResponder()
    return true
}

Answer 1

为了在用户按下键盘上的 Next 时自动将光标移动到下一个数据输入字段，您需要从当前字段中 resignFirstResponder 并使用 becomeFirstResponder 将其分配给下一个字段

if self.emaillabel.isEqual(self.anotherTextField)
 {
    self.anotherTextField.becomeFirstResponder()
 }

Answer 2

1- 为情节提要中的每个文本字段放置一个标签编号

2- 实现 textField 委托函数：

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    if textField.tag == 1 {    //say this is txtFldSponsorID
        txtFldFullName.becomeFirstResponder()
    }
    return true
}

3- 将故事板中的 return 键类型更改为 "next" 而不是 "return"，或者使用代码：

txtFldSponsorID.returnKeyType = .next

4- 不要忘记设置 delegate = self

Answer 3

func textFieldShouldReturn(_ textField: UITextField) -> Bool {

        if textField == txtFldSponsorID {
            txtFldFullName.becomeFirstResponder()
        } else if textField == txtFldFullName {
            txtFldEmail.becomeFirstResponder()
        } else if textField == txtFldEmail {
            txtFldMobile.becomeFirstResponder()
        } else if textField == txtFldMobile {
            txtFldAddress.becomeFirstResponder()
        } else {
            txtFldCity.resignFirstResponder()
        }
        return true
    }

您可以使用上述 UITextField Delegate 方法跳转到下一个 UItextField。
