Keep a view always on top (Don't scroll with keyboard) in IQKeyboardManager

问题

I'm using IQKeyboardManager to keep the text fields to go up after typing with the keyboard.

I don't want to scroll to a specific view even when clicked on the text field. Below is the screenshot of the design. I want the 'header' to remain on top.

From their documentation, there is a way to keep the navigation bar remain on top.

Try this. Disable the IQKeyboardManager for your this viewController.

for that,

IQKeyboardManager.sharedManager().disableInViewControllerClass(your view controller class name here)

And In that viewController write following code. It will move your view up as per keyboard height

override func viewDidLoad() {
        super.viewDidLoad()

        NotificationCenter.default.addObserver(self, selector: #selector(Login.keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(Login.keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)

}

func keyboardWillShow(notification: NSNotification) {

        if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
            if self.view.frame.origin.y == 0{
            self.view.frame.origin.y -= keyboardSize.height
        }
        }

    }

func keyboardWillHide(notification: NSNotification) {
        if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
            if self.view.frame.origin.y != 0{
            self.view.frame.origin.y += keyboardSize.height
        }
        }
    }

Now you want your "HEADER" view remain on TOP then,

Do like this :

YourViewController.view -> [headerView][contentView]

Put textfield in [contentView] And change [contentView].y instead of Self.view in above code.

Disable the IQKeyboardManager for your viewController:

override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)
        IQKeyboardManager.sharedManager().enable = false

        NotificationCenter.default.addObserver(self, selector: #selector(Login.keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(Login.keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

Handle keyboard:

func keyboardWillShow(notification: NSNotification) {

        if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
            if self.view.frame.origin.y == 0{
            self.table_view.frame.origin.y -= keyboardSize.height
            }
        }
    }

func keyboardWillHide(notification: NSNotification) {
        if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
            if self.view.frame.origin.y != 0{
            self.table_view.frame.origin.y += keyboardSize.height
            }
        }
    }

Remove observer:

override func viewWillDisappear(animated: Bool) {
        IQKeyboardManager.sharedManager().enable = true
        NSNotificationCenter.defaultCenter().removeObserver(self)    
    }
