I'm trying to use JSQMessagesVC in my Swift 3 project. It was installed via cocoa pods and everything looks fine. The problem is I can't implement collectionView methods and a keep getting errors. Can anyone help me?
import UIKit
import JSQMessagesViewController
class ChatViewController: JSQMessagesViewController {
var messages = [JSQMessage]()
override func viewDidLoad() {
super.viewDidLoad()
collectionView!.delegate = self
collectionView!.dataSource = self
collectionView!.collectionViewLayout.incomingAvatarViewSize = CGSize.zero
collectionView!.collectionViewLayout.outgoingAvatarViewSize = CGSize.zero
}
override func collectionView(_ collectionView: JSQMessagesCollectionView, messageDataForItemAt indexPath: IndexPath) -> JSQMessageData {
return messages[indexPath.item]
}
override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return messages.count
}
override func collectionView(_ collectionView: JSQMessagesCollectionView!, messageBubbleImageDataForItemAt indexPath: IndexPath!) -> JSQMessageBubbleImageDataSource! {
let message = messages[indexPath.item] // 1
if message.senderId == senderId { // 2
return outgoingBubbleImageView
} else { // 3
return incomingBubbleImageView
}
}
override func collectionView(_ collectionView: JSQMessagesCollectionView!, avatarImageDataForItemAt indexPath: IndexPath!) -> JSQMessageAvatarImageDataSource! {
return nil
}
lazy var outgoingBubbleImageView: JSQMessagesBubbleImage = self.setupOutgoingBubble()
lazy var incomingBubbleImageView: JSQMessagesBubbleImage = self.setupIncomingBubble()
private func setupOutgoingBubble() -> JSQMessagesBubbleImage {
let bubbleImageFactory = JSQMessagesBubbleImageFactory()
return bubbleImageFactory!.outgoingMessagesBubbleImage(with: UIColor.jsq_messageBubbleBlue())
}
private func setupIncomingBubble() -> JSQMessagesBubbleImage {
let bubbleImageFactory = JSQMessagesBubbleImageFactory()
return bubbleImageFactory!.incomingMessagesBubbleImage(with: UIColor.jsq_messageBubbleLightGray())
}
// override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
// //Your Logic here
// }
}
