Messagekit: Message Input Bar Flickering On New Line

[azhararmar]

General Information

• MessageKit Version: 0.1.0

• iOS Version(s): 10.3.2

• Swift Version: 4

• Devices/Simulators: iPhone 6s Device & Simulator

• Reproducible in ChatExample? (Yes/No): Yes

What happened?

When the message reaches end of line in input bar, the message goes to next line with a flicker, i.e the message input bar looks kind of closing and re-opening on every new line.

What did you expect to happen?

Can we remove this flickering when going to new line on message input bar? this kind of feels weird.

@azhararmar Interesting, I am having trouble seeing this flickering. Even when I slow the simulators animation time

PFA the screenshot in GIF format. I tested this in iOS11 simulator and the issue exist for me.

I am running the simulator with default settings.

Hi @azhararmar , I can't yet reproduce this in the ChatExample app. Are you using some kind of custom View controller container where your MessagesViewController is a child view controller? Have you overriden or changed any default values of the MessagesViewController

Hi @nathantannar4. I tested this further and I come to understand this issue is shown when IQKeyboardManager is enabled. The solution is to disable IQKeyboardManager in the ViewController with following code.

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

override func viewDidDisappear(_ animated: Bool) {
    super.viewDidDisappear(animated)
    IQKeyboardManager.sharedManager().enable = true
}

There are several users who uses IQKeyboardManager library. Perhaps if we can add a note in the documentation warning the user to disable IQKeyboardManager in the ViewController to avoid the conflict.

I will close this issue for now.

Hey @azhararmar thanks for updating us and documenting this for other users 👍

Ah yes @azhararmar we already manage the keyboard state.

Hi @nathantannar4 -
Even after removing IQKeyboardManager entirely from my project (I uninstalled the pod) my app still flickers (more like pauses) when it's preparing to go to a new line. What info can I give you to help get to the bottom of it? Thanks!
