Calling reloadInputAccessoryView after view is collapsed causes a crash

[reygonzales]

The app crashes if the input view is reloaded (with reloadInputAccessoryView) when the view is collapsed.

- (void)_updateInputViewFrameWithKeyboardFrame:(CGRect)keyboardFrame
                                   forceReload:(BOOL)reload
{
    // If the keyboardFrame equals CGRectZero and
    // the inputView is not visible yet, we won't be able
    // to access the keyboard's frame.
     #ifdef DEBUG
          NSCAssert(!(CGRectEqualToRect(keyboardFrame, CGRectZero) &&
                self.inputView.superview == nil), nil);
     #endif

I need to refresh the view when it is collapsed -- the user can still hit "Send"

Multiple people have reported this already and it obviously has to do with the assert but I did put that assert there for a reason. I haven't been able to reproduce the crash myself, do you have a sample project I can take a look at by any chance?

[reygonzales]

I don't have sample code but its pretty easy to replicate

1. Write text in inputView
2. Collapse view
3. Call [self.contentWrapper reloadInputAccessoryView];

[datwelk]

That function does no longer exist. Does it help to use the latest code from the master branch?

[reygonzales]

Ah, I'm using a cocoapod

I'll update my cocoa pod to point to master and see if its still a problem.

[reygonzales]

Well, it doesn't crash now that I don't have access to it.

So how do I reset the size of the text view now?

(Thanks by the way, this library is awesome)

[datwelk]

Thanks, I try :-)

What exactly do you want to achieve? I assume you pressed the return key several times and collapsed the keyboard afterwards, which causes the textview to keep its height to accommodate for the linebreaks. This behavior can be found in apps such as Whatsapp as well, except that Whatsapp does not allow a linebreak character as the first character in the textview. If that is what you want in your app, you could implement inputViewKeyboard.textView's delegate.

👍

This is what I did

1: Type text in the text field

     Peanut butter
     AND
     Jelly!

2: "Send" the text to the server
3: Clear the text view

---

In a way I'm trying to get it to behave like the messages app when you're sending a paragraph to someone. After its sent, the text view shrinks to one line

[datwelk]

Ah, that makes sense. Will think about a solution. Feel free to file a pull request when you've found a (neat) solution yourself.

Hey @reygonzales did you ever find a workaround for this?
