JLChatViewController

[](https://travis-ci.org/José Lucas/JLChatViewController)

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

If you want to use this framework you will need at least IOS 8!

Installation

JLChatViewController is available through CocoaPods. To install it, simply add the following line to your Podfile:

    pod "JLChatViewController"

News on version 2.0.0

CPU usage improvements

IMPORTANT =  These and other improvements made necessary some changes on implementations of delegates, some methods were deprecated , so its important you take a look again on example project to make the right corrections.

Customization improvements

- Now you can use your own bubble form images with simple and fast configuration

- Now you can add custom header views for example use your own Date Header View, use one for indicating the number of unread messages

Animations improvements

New component added

`JLChatLabel` was added to substitute the `JLChatTextView` on `JLTextMessageCell` specially for performance.I advice you to use `JLChatLabel` instead of `JLChatTextView` when possible .

Some methods were deprecated

Initial Configurations

First Step

  Import it on every file that you will use this framework.

import JLChatViewController

Second Step

  Call this method on AppDelegate for you load the `JLChat.storyboard`, but you can call it where you prefer.

JLBundleController.loadJLChatStoryboard()

Third Step

  Your ViewController that will have the chat must inherit from `JLChatViewController` and implement all these protocols: 
    `ChatDataSource`,`ChatToolBarDelegate`,`JLChatMessagesMenuDelegate`,`ChatDelegate`.

Fourth Step

  Find `JLChat.storyboard` open it, choose the ViewController and put your ViewController that inherits from `JLChatViewController` as the class of this one.

Fith Step(Added on version 2.0.0)

You will need some way to know the correctly number of sections(Date sections and/or custom sections), the number of messages by section on your chat. 
If you have some doubt about it take a look on Mark `Chat messages by section methods` of MyViewController

Quick Tips

Configuring your messages

Change the parameters values as you prefer
The example project has some ways of customization implemented

-If you want to use custom bubbles images I advise you to use images with 32x32 pixels for @1x

JLChatAppearence.configIncomingMessages(WithCustomBubbleImage: UIImage(named: "custom-incomingBubble"), customBubbleInsets: UIEdgeInsets(top: 14, left: 14, bottom: 14, right: 14), bubbleImageMask: UIImage(named: "custom-incomingBubbleMask"), bubbleMaskInsets: UIEdgeInsets(top: 14, left: 14, bottom: 14, right: 14), incomingBubbleColor: nil, showIncomingSenderImage: true, incomingTextColor: nil)

JLChatAppearence.configOutgoingMessages(WithCustomBubbleImage: UIImage(named: "custom-outgoingBubble"), customBubbleInsets: UIEdgeInsets(top: 14, left: 14, bottom: 14, right: 14), bubbleImageMask: UIImage(named: "custom-outgoingBubbleMask"), bubbleMaskInsets: UIEdgeInsets(top: 14, left: 14, bottom: 14, right: 14), outgoingBubbleColor: nil, showOutgoingSenderImage: true, outgoingTextColor: nil)

-If you want to use default bubbles images

JLChatAppearence.configIncomingMessages(nil, showIncomingSenderImage: true, incomingTextColor: nil)

JLChatAppearence.configOutgoingMessages(nil, showOutgoingSenderImage: true, outgoingTextColor: nil)

-This method is optional, it is normally used when you are using custom bubbles images, but fell free to use it when ever you want.

JLChatAppearence.configAligment(5, vertivalDistBetweenImgBottom_And_BubbleBottom: 10)

-This method is optional, it is normally used when you are using custom bubbles images, but fell free to use it when ever you want.

JLChatAppearence.configTextAlignmentOnBubble(IncomingMessTextAlig: UIEdgeInsets(top: 8, left: 10, bottom: 13, right: 8), AndOutgoingMessTextAlig: UIEdgeInsets(top: 8, left: 8, bottom: 13, right: 10))

JLChatAppearence.configSenderImage(nil, senderImageCornerRadius: nil, senderImageBackgroundColor: nil, senderImageDefaultImage: nil)


JLChatAppearence.configErrorButton(nil, selectedStateImage: nil)

Adding new message

More information take a look on documentation

public func addNewMessages(quant:Int,changesHandler:()->(),completionHandler:(()->())?)

Adding old messages

public func addOldMessages(quant:Int,changesHandler:()->())

Removing one message cell

public func removeMessageCellAtIndexPath(indexPath:NSIndexPath,relatedMessage:JLMessage!)

Removing one section(Date section or custom section)

public func removeChatSection(section:Int,messagesOfSection:[JLMessage]?)

Removing more than one message cell and or more than one section

public func removeMessagesCells(rowsIndexPath:[NSIndexPath]?,AndSections sections:[Int]?,WithRelatedMessages relatedMessages:[JLMessage]?)

Updating a message cell send status

public func updateMessageStatusOfCellAtIndexPath(indexPath:NSIndexPath,message:JLMessage)

Open your chat ViewController

Use it to open your Chat ViewController

if let vc = JLBundleController.instantiateJLChatVC() as? /*Name of your ViewController that inherits from            JLChatViewController*/{
            
      vc.view.frame = self.view.frame
            
      let chatSegue = UIStoryboardSegue(identifier: "identifier name", source: self, destination: vc, performHandler: { () -> Void in
                
            self.navigationController?.pushViewController(vc, animated: true)
      })
            
      self.prepareForSegue(chatSegue, sender: nil)
            
      chatSegue.perform()
}

Creating a custom cell

First Step

  Create a class that inherits from `JLChatMessageCell` and implement all necessary methods , more details on example project

Second Step

  Create a .xib file that have a `UITableViewCell` and add all necessary views, more details on example project.
  Attention! there are some constraints of errorButton and senderImageView that must have to exist, for everything works well , more details take a look on custom cell of the example project.

Third Step

  Register them on your chat tableView

self.chatTableView.registerNib(UINib(nibName: "nib name", bundle: NSBundle.mainBundle()), forCellReuseIdentifier: "identifier")

Fourth Step

  implement the method of `ChatDataSource` that is for custom cells

func chat(chat: JLChatTableView, customMessageCellForRowAtIndexPath indexPath: NSIndexPath) -> JLChatMessageCell {


      ...
        
      var cell:JLChatMessageCell!
      if message.senderID == self.chatTableView.myID{
            cell = self.chatTableView.dequeueReusableCellWithIdentifier("your identifier for outgoing message") as! CellName
      }
      else{
            cell = self.chatTableView.dequeueReusableCellWithIdentifier("your identifier for incoming message") as! CellName

      }
        
        
      return cell
        
}

Creating a custom Header View

First Step

Create a .xib file that have a UIView and add all necessary views, more details on example project.

Second Step

Register it on your chat tableView

self.chatTableView.registerNib(UINib(nibName: "nib name", bundle: NSBundle.mainBundle()), forHeaderFooterViewReuseIdentifier: "identifier")

Third Step

implement the methods of ChatDataSource that is for custom cells

func jlChatCustomHeaderInSection(section:Int)->UIView?


func jlChatHeightForCustomHeaderInSection(section:Int)->CGFloat
