swift iMessage style keyboard input - swift

Question

i am trying to implement an iMessage style keyboard input with a textview that sits at the bottom of the screen then slides up with the keyboard when you touch the textView, then is docked to the top of the keyboard.
I found MessageComposerView which is exactly what I want. Unfortunately I cannot get it working ( I am using swift).
below is my code:
import UIKit
class CommentsViewController: UIViewController, MessageComposerViewDelegate {
var messageComposerView: MessageComposerView!
override func viewDidLoad() {
super.viewDidLoad()
let defaultWidth = view.frame.size.width
let defaultHeight = CGFloat(54.0)
let subviewFrame = CGRect(x: 0, y: view.frame.height - defaultHeight, width: defaultWidth, height: defaultHeight)
messageComposerView = MessageComposerView(frame: subviewFrame) as MessageComposerView
view.addSubview(messageComposerView)
}
func messageComposerSendMessageClickedWithMessage(message: String!) {
}
}
however it does not show up. Ive printed the view and its frame is correct, its just that there is nothing there for some reason. Everything looks like it should be working. Does anyone see anything wrong with my current implementation?

Answer 1

Try PHFComposeBarView Library (https://github.com/fphilipe/PHFComposeBarView), it's a exact copy of the iMessage composer bar that can be used in C & Swift from storyboard or code
Code Example : https://github.com/liveminds/SwiftPHFComposeBarTest
Storyboard Example : https://github.com/liveminds/SwiftPHFComposeBarTest/tree/storyboard-managed
To add the bar to your view:
drag a new UIView on your UIViewcontroller, assign "PHFComposeBarView" class to UIView
Add an outlet of the UIView to your Viewcontroller's class
add "PHFComposeBarViewDelegate" to your Viewcontroller's class
assign UIView Delegate in viewdidload() : self.composerBarOutlet.delegate = self
Set the composer bar to appear as inputAccessoryView above the keyboard:
override var inputAccessoryView: UIView {
composerBar.removeFromSuperview()
return composerBar
}
Style your Bar(example):
composerBar.utilityButtonImage = UIImage(named: "fullStar")!
composerBar.buttonTitle = "Submit"
composerBar.maxCharCount = 200
composerBar.maxLinesCount = 5
composerBar.alpha = 1.0
composerBar.buttonTintColor = AppConfig.BLUECOLOR
composerBar.placeholder = "What do you think about this product?"

Try following this example by Andrew Bancroft Send Text Message In-App – Using MFMessageComposeViewController with Swift. His example provides a nice walkthrough using Swift and includes sample code on GitHub.
Just going from the code snippet included in your post, it looks like you need to import Foundation, import MessageUI, conform to the MFMessageComposeViewControllerDelegate protocol, and implement the messageComposeViewController protocol method. All of this is covered in Andrew's blog post. This should give you what you're looking for.

Have you find the answer yet?
I use the same Framework however I believe you need to set up the delegate to self. IN my case it fails though I dont know why but it is written down in the readme github.
