ios - 带有用于关闭键盘垫的 uibar 的文本字段

Question

我创建了一个申请表，在某些字段中我使用数字键盘。由于缺少关闭按钮，我进入了包含关闭按钮的 uibar。

我目前为每个字段创建一个 uibar，因为我必须指定目标。是否可以只创建一个具有多个目标的 uibar？

@IBOutlet weak var TXTNome: UITextField!
@IBOutlet weak var TXTAltezza: UITextField!
@IBOutlet weak var TXTPeso: UITextField!
@IBOutlet weak var TXTEta: UITextField!

// Altezza
    let keyboardToolbar = UIToolbar(frame: CGRect(x: 0, y: 0,
                                                  width: self.view.bounds.size.width,
                                                  height: 44))
    keyboardToolbar.barStyle = UIBarStyle.blackTranslucent
    keyboardToolbar.backgroundColor = UIColor.red
    keyboardToolbar.tintColor = UIColor.white

    let flex = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
    let save = UIBarButtonItem(title: "Chiudi",
                               style: .done,
                               target: TXTAltezza,
                               action: #selector(resignFirstResponder))
    keyboardToolbar.setItems([flex, save], animated: false)
    TXTAltezza.inputAccessoryView = keyboardToolbar

    // Peso
    let keyboardToolbar2 = UIToolbar(frame: CGRect(x: 0, y: 0,
                                                   width: self.view.bounds.size.width,
                                                   height: 44))
    keyboardToolbar2.barStyle = UIBarStyle.blackTranslucent
    keyboardToolbar2.backgroundColor = UIColor.red
    keyboardToolbar2.tintColor = UIColor.white

    let flex2 = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
    let save2 = UIBarButtonItem(title: "Chiudi",
                                style: .done,
                                target: TXTPeso,
                                action: #selector(resignFirstResponder))
    keyboardToolbar2.setItems([flex2, save2], animated: false)
    TXTPeso.inputAccessoryView = keyboardToolbar2

等等等等

Answer 1

        let toolBar = UIToolbar()
        toolBar.barStyle = UIBarStyle.default
        toolBar.isTranslucent = true
        toolBar.sizeToFit()
        let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.plain, target: self, action: #selector(doneClickOk))
        toolBar.setItems([doneButton], animated: false)
        toolBar.isUserInteractionEnabled = true
        yourTextField.inputAccessoryView = toolBar
        yourOthersTextfields.inputAccessoryView = toolBar


**Than call selector method** 

@objc func doneClickOk(){
    view.endEditing(true)
}
