I have created a class of message including, content and sender. I successfully store the desired data in Parse and I am querying them. So far, no problem. Then, I attempt to filter the messages according to the sender, or the receiver, in order to display them in different manners on my tableView. For instance, let's say that is sender is currentUser, the text is blue, otherwise it is green. If currentUser sends a message, all the text becomes blue, even the one sent by the other user; and vice versa.
class Message {
var sender = ""
var message = ""
var time = NSDate()
init(sender: String, message: String, time: NSDate)
{
self.sender = sender
self.message = message
self.time = time
}
}
var message1: Message = Message(sender: "", message: "", time: NSDate())
func styleTextView()
{
if message1.sender == PFUser.currentUser()?.username {
self.textView.textColor = UIColor.blueColor()
} else {
self.textView.textColor = UIColor.greenColor()
}
}
func addMessageToTextView(message1: Message)
{
textView.text = message1.message
self.styleTextView()
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
var cell: messageCell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! messageCell
let message = self.array[indexPath.row]
cell.setupWithMessage(message)
return cell
}
I have other codes on my viewController, however I believe they are irrelevant to this matter; if needed, I can provide them. Any idea why I cannot have the textViews in different style according to the sender? They are all either blue, either green.
Below is the code for the full set up of the tableViewCell:
class messageCell: UITableViewCell {
private let padding: CGFloat = 10.0
var array1 = [Message]()
private func styleTextView()
{
let halfTextViewWidth = CGRectGetWidth(textView.bounds) / 2.0
let targetX = halfTextViewWidth + padding
let halfTextViewHeight = CGRectGetHeight(textView.bounds) / 2.0
self.textView.font = UIFont.systemFontOfSize(12.0)
if PFUser.currentUser()?.username == message1.sender && textView.text == message1.message {
self.textView.backgroundColor = UIColor.blueColor()
self.textView.layer.borderColor = UIColor.blueColor().CGColor
self.textView.textColor = UIColor.whiteColor()
textView.center.x = targetX
textView.center.y = halfTextViewHeight
} else {
self.textView.backgroundColor = UIColor.orangeColor()
self.textView.layer.borderColor = UIColor.orangeColor().CGColor
self.textView.textColor = UIColor.whiteColor()
self.textView.center.x = CGRectGetWidth(self.bounds) - targetX
self.textView.center.y = halfTextViewHeight
}
}
private lazy var textView: MessageBubbleTextView = {
let textView = MessageBubbleTextView(frame: CGRectZero, textContainer: nil)
self.contentView.addSubview(textView)
return textView
}()
class MessageBubbleTextView: UITextView
{
override init(frame: CGRect = CGRectZero, textContainer: NSTextContainer? = nil)
{
super.init(frame: frame, textContainer: textContainer)
self.scrollEnabled = false
self.editable = false
self.textContainerInset = UIEdgeInsets(top: 7, left: 7, bottom: 7, right: 7)
self.layer.cornerRadius = 15
self.layer.borderWidth = 2.0
}
required init(coder aDecoder: NSCoder)
{
fatalError("init(coder:) has not been implemented")
}
}
private let minimumHeight: CGFloat = 30.0
private var size = CGSizeZero
private var maxSize: CGSize {
get {
let maxWidth = CGRectGetWidth(self.bounds)
let maxHeight = CGFloat.max
return CGSize(width: maxWidth, height: maxHeight)
}
}
func setupWithMessage(message: Message) -> CGSize
{
textView.text = message.message
size = textView.sizeThatFits(maxSize)
if size.height < minimumHeight {
size.height = minimumHeight
}
textView.bounds.size = size
self.styleTextView()
return size
}
}
