here i want to use this function which i have mention in custom subclass of uiview
this is messageviewcontroller file
import UIKit
class MessageViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
var MessageData : NSMutableArray!
@IBOutlet weak var tableviee: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
MessageData = NSMutableArray()
MessageData.add(getMessageListData(image: "ProfileImageRound", profileName: "Silvestor Young", profileMessage: "Hi, I want to purchase your service, can you please provide it to me", Messagtime: "10 min ago"))
MessageData.add(getMessageListData(image: "ProfileImageRound", profileName: "Welma Simpson", profileMessage: "How much is it cost to repeate it again", Messagtime: "22 min ago"))

tableviee.register(UINib(nibName: "MessageMainCell", bundle: nil), forCellReuseIdentifier: "MessageMainCell")
let messageBar = MessageBar.instanceFromNib() as! MessageBar
self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: messageBar)
}

return cell
}

}
}
import UIKit
class MessageDetailbar: UIView {
@IBOutlet weak var time: UILabel!
@IBOutlet weak var name: UILabel!
@IBOutlet weak var imageView: UIImageView!

}
if let Name = data["profileName"] as? String{
name.text = Name
}
if let Time = data["Messagetime"] as? String{
time.text = Time
}
}
}
here i have used my customview in viewwillAppear
import UIKit
class MessageDetailViewController: UIViewController {
@IBOutlet weak var tableview: UITableView!
struct data{
let time: String
let message: String
let date: String
let type: String
}
struct section {
let date: String
var array = [data]()
}
let sectionArray = [
section(date: "yesterday", array: [
data(time: "3:30 PM", message: "I am looking for your service, can you please give more information on that.", date: "yesterday", type: "sender"),
data(time: "3:40 PM", message: "Sure i am here to help you", date: "yesterday", type: "receiver")
]),
section(date: "today", array: [
data(time: "4:40 PM", message: "Ok, I wil contact you on your phone for that.", date: "today", type: "sender"),
data(time: "5: 30 PM", message: "SO HERRE IS my contact number 9586670629", date: "today", type: "receiver"),
data(time: "5: 30 PM", message: "OKAY I will call back you within 15 20 minitues", date: "today", type: "sender")
])
]
override func viewDidLoad() {
super.viewDidLoad()
self.tableview.register(UINib(nibName: "SenderCell", bundle: nil), forCellReuseIdentifier: "SenderCell")
self.tableview.register(UINib(nibName: "ReceiverCell", bundle: nil), forCellReuseIdentifier: "ReceiverCell")
self.tableview.register(UINib(nibName: "customHeaderViewCell", bundle: nil), forCellReuseIdentifier: "customHeaderViewCell")
}
override func viewWillAppear(_ animated: Bool) {
let messageDetailBar = MessageDetailbar.instanceFromNib() as! MessageDetailbar
self.navigationItem.titleView = messageDetailBar
}
}
extension MessageDetailViewController: UITableViewDelegate, UITableViewDataSource{
func numberOfSections(in tableView: UITableView) -> Int {
return sectionArray.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return sectionArray[section].array.count
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
self.tableview.deselectRow(at: indexPath, animated: true)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if sectionArray[indexPath.section].array[indexPath.row].type == "sender"
{
let cell = tableview.dequeueReusableCell(withIdentifier: "SenderCell", for: indexPath) as! SenderCell
cell.setData(reciverTime: sectionArray[indexPath.section].array[indexPath.row].time, reciverMsg: sectionArray[indexPath.section].array[indexPath.row].message)
return cell
}
else
{
let cell = tableView.dequeueReusableCell(withIdentifier: "ReceiverCell", for: indexPath) as! ReceiverCell
cell.setData(reciverTime: sectionArray[indexPath.section].array[indexPath.row].time, reciverMsg: sectionArray[indexPath.section].array[indexPath.row].message)
return cell
}
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let headerView = UIView()
let headerCell = tableView.dequeueReusableCell(withIdentifier: "customHeaderViewCell") as! customHeaderViewCell
if sectionArray[section].date == "yesterday"
{
headerCell.labelHeader.text = "yesterday"
}
else
{
headerCell.labelHeader.text = "today"
}
headerView.addSubview(headerCell)
return headerView
}
}
but i am not able to use it how can use it proper way
i want to use custom navigation bar when on of the cell is selected [this] cell2 to [this] navigation bar 3
You don't show your MessageDetailViewController or how you're passing the data from the selected index path, but assuming you have something like this:
class MessageDetailViewController: UIViewController {
public var theData: NSDictionary!
you'll be passing the data in didSelectRowAt like this:
let stroryBoard = UIStoryboard(name: "Main", bundle: nil)
let rootVc = stroryBoard.instantiateViewController(withIdentifier: "MessageDetailViewController") as! MessageDetailViewController
// unwrap optional
guard let setData = MessageData.object(at: indexPath.row) as? NSDictionary else { return }
// pass the data to the Detail controller
rootVc.theData = setData
self.navigationController?.pushViewController(rootVc, animated: true)
Then, in viewDidLoad() in MessageDetailViewController:
class MessageDetailViewController: UIViewController {
public var theData: NSDictionary!
override func viewDidLoad() {
super.viewDidLoad()
// whatever else you're doing to congfigure
// this controller
// get an instance of MessageDetailbar
let messageDetailBar = MessageDetailbar.instanceFromNib() as! MessageDetailbar
// set the data
messageDetailBar.setBarData(data: theData)
// set it as the navigation bar's titleView
self.navigationItem.titleView = messageDetailBar
}
}
As a side note, override intrinsicContentSize in your MessageDetailbar class so it will fill the available horizontal space:
class MessageDetailbar: UIView {
@IBOutlet weak var time: UILabel!
@IBOutlet weak var name: UILabel!
@IBOutlet weak var imageView: UIImageView!
class func instanceFromNib() -> UIView {
return UINib(nibName: "MessageDetailbar", bundle: nil).instantiate(withOwner: nil, options: nil)[0] as! UIView
}
func setBarData(data: NSDictionary){
if let image = data["image"] as? String{
imageView.image = UIImage(named: image)
}
if let Name = data["profileName"] as? String{
name.text = Name
}
if let Time = data["Messagetime"] as? String{
time.text = Time
}
}
// add this
override var intrinsicContentSize: CGSize {
return UIView.layoutFittingExpandedSize
}
}
