關閉鍵盤以及使用IQKeyboardManager

我在的appdelegate關閉鍵盤以及使用IQKeyboardManager

IQKeyboardManager.sharedManager().enable = true 
IQKeyboardManager.sharedManager().shouldResignOnTouchOutside = true 
IQKeyboardManager.sharedManager().touchResignedGestureIgnoreClasses = [UINavigationBar.self,UIControl.self]

分配touchResignedGestureIgnoreClasses屬性允許，如果鍵盤打開我火了UIButton的情況下使用此代碼消防按鈕的touchupinside事件，但它不會解散鍵盤同時。

IQKeyboardManager不會取消鍵盤，如果你是通過包括在** touchResignedGestureIgnoreClasses控制執行任何操作**，所以，你已經包括您的UIButton –

@Jayachandra一個我應該怎麼做然後..如果我跳過從這個屬性的UIbutton，它只是駁回鍵盤的事件不會被解僱 –

嘗試添加該行自己的函數中的代碼來處理按鈕的事件：

self.view.endEditing = true

是的，我可以使用這個，但爲此，我已經在每個控制器中添加此行。但我想要一個通用的解決方案。 –

在這種特定的情況下，您可能需要創建自己的按鈕類子類的UIButton和觀察裏面的事件。稍後，將UIButtons自定義類指定爲您已創建的自己的按鈕。

class KOButton: UIButton { 

    var isKeyBoardOpened = false 

    // Only override draw() if you perform custom drawing. 
    // An empty implementation adversely affects performance during animation. 
    override func draw(_ rect: CGRect) { 
     // Drawing code 

     self.addObserver(self, forKeyPath: "highlighted", options: .new, context: nil) 
     NotificationCenter.default.addObserver(self, selector: #selector(keyboardOpened), name: Notification.Name.UIKeyboardDidShow, object: nil) 
    } 

    override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) { 
     if keyPath == "highlighted" { 
      UIApplication.shared.keyWindow?.endEditing(true) 
      self.isKeyBoardOpened = false 
     } 
    } 

    func keyboardOpened() { 
     isKeyBoardOpened = true; 
    } 


}

我希望這力量可以幫助你，如果我以前不工作請按照下面的另一種方法中提到

寫出擴展的UIViewController

// Declare a global var to produce a unique address as the assoc object handle 
private var AssociatedObjectHandle: UInt8 = 0 
extension UIViewController{ 

    var isKeyBoardOpened: Bool { 
     get { 
      return objc_getAssociatedObject(self, &AssociatedObjectHandle) as! Bool 
     } 
     set { 
      objc_setAssociatedObject(self, &AssociatedObjectHandle, newValue, objc_AssociationPolicy.OBJC_ASSOCIATION_RETAIN_NONATOMIC) 
     } 
    } 


    func addKBOforButton(aButton: UIButton) { 
     aButton.addObserver(self, forKeyPath: "highlighted", options: .new, context: nil) 
     NotificationCenter.default.addObserver(self, selector: #selector(keyboardOpened), name: Notification.Name.UIKeyboardDidShow, object: nil) 
    } 

    override open func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) { 
     if keyPath == "highlighted" { 
      UIApplication.shared.keyWindow?.endEditing(true) 
      self.isKeyBoardOpened = false 
     } 
    } 

    func keyboardOpened() { 
     isKeyBoardOpened = true; 
    } 
}

然後從您的視圖控制器調用此功能

self.addKBOForButton(aButton: button)

我可以在ViewController擴展中聲明這些函數而不是uibutton類，並在viewdidload中調用它，以便每個控制器繼承此功能？ –

它沒有爲我工作 –
