ScrollView did not move up when click textfield inside tableView

问题

I tried this code : in viewWillAppear :

NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillDisappear), name: Notification.Name.UIKeyboardWillHide, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillAppear), name: NSNotification.Name.UIKeyboardWillShow, object: nil)

and :

@objc func keyboardWillAppear(notification:NSNotification) {
    print("keyboard appear")
    var info = notification.userInfo
    let keyBoardSize = info![UIKeyboardFrameEndUserInfoKey] as! CGRect
    scrollCreateEditContact.contentInset = UIEdgeInsetsMake(0.0, 0.0, keyBoardSize.height, 0.0)
    scrollCreateEditContact.scrollIndicatorInsets = UIEdgeInsetsMake(0.0, 0.0, keyBoardSize.height, 0.0)
}

@objc func keyboardWillDisappear(notification:NSNotification) {
    print("keyboard disappear")
    scrollCreateEditContact.contentInset = UIEdgeInsets.zero
    scrollCreateEditContact.scrollIndicatorInsets = UIEdgeInsets.zero
}

and result is :

what I want is that textfield did not covered by keyboard when keyboard appear like this :

That code only work on textfield that is not inside tableView. But when I click textfield inside tableView and log it "keyboard appear" always detected.

What is the correct code for textfield inside tableView not covered by keyboard when keyboard appear?

回答1:

The easiest way to handle this problem is installing pod for IQKeyboardManager:

Installation via cocoa pods:

pod 'IQKeyboardManagerSwift'

Usage:

import IQKeyboardManagerSwift

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

      IQKeyboardManager.shared.enable = true

      return true
    }
}

Thats common behaviour, ios cannot adjust content above keyboard automatically, unlike android. My solution is, you can wrap all that views (photo, textfield, etc) inside tableView. And use TPKeyboardAvoiding library.
