Hi @KennethTsang! 😄 First off, great job with this library! As the title suggests, I am suggesting that when the maxHeight is updated, that layoutSubviews be called immediately to update the heightConstraint. For my use case, I am working on something where the maxHeight of the text view is constantly changing depending on certain factors within my app.

Line 100 in GrowingTextView.swift will need to be removed because even though the text and width may be the same, the maxHeight may not be.

Let me know what you think! 👍

Just copied the source into my project, dropped a textview onto my viewcontroller, changed the class to GrowingTextView and when I run, the keyboard overlays the textview?

So in my case I have a tableview and want to add this at the bottom. I created a view, dropped a textview in it (just as in the example 2). What I don't understand is how this resizes the tableview while the keyboard is open?

Hello, thanks for the great library!

I'm trying to use it inside UITableViewCell with all edges pinned to edges of cell, so tableviewcell should grow height with textview size change. I've adopted self sizing textview, as described here http://candycode.io/self-sizing-uitextview-in-a-uitableview-using-auto-layout-like-reminders-app/

While it works fine with regular UITextView, when I change it to GrowingTextView - I constantly receive following error with constraints (it seems GrowingTextView tries to update height costraint before it should do so):

[LayoutConstraints] Unable to simultaneously satisfy constraints.
	Probably at least one of the constraints in the following list is one you don't want. 
	Try this: 
		(1) look at each constraint and try to figure out which you don't expect; 
		(2) find the code that added the unwanted constraint or constraints and fix it.

Will attempt to recover by breaking constraint

I have some sample code below where I try to mimic the dynamic text view calculation like your code. My question is how is the top inset addressed with respect to the text container? When I get to about the second line, my first line shifts up pretty much to very edge of the top frame of Text View. I want the text to stay center to the line height.

import UIKit

class ViewController: UIViewController, UITextViewDelegate {

    @IBOutlet weak var textView: UITextView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.textView.delegate = self
        self.textView.backgroundColor = .lightGray
    }
    
    func textViewDidChange(_ textView: UITextView) {
        self.calculateSize()
    }

    func calculateSize() {
        let fixedWidth = textView.frame.size.width
        textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.greatestFiniteMagnitude))
        let newSize = textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.greatestFiniteMagnitude))
        var newFrame = textView.frame
        newFrame.size = CGSize(width: max(newSize.width, fixedWidth), height: newSize.height)
        textView.frame = newFrame
    }
}

If you don't define the textViewDidChangeHeight "optional" method from the delegate, it crashes. So i don't actually need that method from the delegate. So for now, i'm calling the method, but leave it empty.

I have app crashed by using this library, the reason is "Could not instantiate class named _UITextLayoutView because no class named _UITextLayoutView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)". If there is any body have same issue please let me know how to resolved this issue, thanks

It's mentioned in Readme.md file that for Swift 5 you need to use 0.7 version. But if i use that version. It's settings still shows Swift 4 as language and compiler throws error that Swift 5 conversion is available

Having an issue when wanting to adjust the inset of the text. I'd like to add a padding to the inside so the text starts further away from the edge of the text view. Currently the text indicator is too close to edge.

Current

Trying to change the content inset gives this outcome:

messageField.textContainerInset = UIEdgeInsets(top: 0, left: 0.5, bottom: 0, right: 0)

Ideas?

error: IB Designables: Failed to render and update auto layout status for UIView (i5M-Pr-FkT): dlopen(GrowingTextView.framework, 1): no suitable image found. Did find: GrowingTextView.framework: required code signature missing for 'GrowingTextView.framework'

getting this error for days and nothing could fix it , any idea ?

Built directly on top of example storyboard, example 1 runs fine, but both 2 & 3 failed.

Both would complain of height constraints missing. Yet after resolving conflicts by adding missing constraints, textView wouldn't grow as expected. Wondering whether we need to do something more for iOS 11.

Hi, thanks for good work. But... bug: just enter fast some lines like this: http://joxi.ru/DrlBkR0i4bW4j2

layoutSubviews infinite calls, CPU usage 100%

I want to add attributed placeholder to textView which if type GrowingTextView. But it shows error "Ambiguous use of "attributedPlaceholder". I guess the name of the placeholder attribute should be changed to something different as UItextView already has placeholder attribute.

I've been using your library for years without problems. Recently I had to resume a project which I haven't touched in several months, so I'm not sure if this is now an iOS 13.3 issue or what, but the textview would just not work.

Until I went into the soucecode of the GrowingTextView and added setNeedsLayout here:

    // Limit the length of text
    @objc func textDidChange(notification: Notification) {
        if let sender = notification.object as? GrowingTextView, sender == self {
            if maxLength > 0 && text.count > maxLength {
                let endIndex = text.index(text.startIndex, offsetBy: maxLength)
                text = String(text[..<endIndex])
                undoManager?.removeAllActions()
            }
            setNeedsDisplay()
            setNeedsLayout() <-- HERE
        }
    }

Then everything works as expected. Is this normal? If not, why could it be happening?

If you press the backspace quickly and continuously, there are bugs that temporarily do not change the vertical size. Can you fix the problem? Thank you.

In my case, I have chat screen which supports arabic and english language and when I am using your lib, it doesn't showing globe button to change keyboard. Is there some settings to change? Also can't paste arabic or emoji in textview.
