i am trying to call the viewDidLoad of view controllers only once while using SWRevealViewController.I am following these tutorial
and want to do a little change loading the view controllers programmatically instead of using segues..
I tried to set the frontview controller in MenuController class as
class MenuController: UITableViewController {
var navcontroller: UINavigationController?
override func viewDidLoad() {
super.viewDidLoad()
navcontroller = self.storyboard?.instantiateViewControllerWithIdentifier("pager") as? UINavigationController
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func viewWillAppear(animated: Bool) {
println("ok this i get called")
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if indexPath.row == 2{
if let temp = navcontroller{
self.revealViewController().setFrontViewController(navcontroller!, animated: true)
}else{
println("navigation controller contains nil vaue")
}
}
}
}
The problem i get is i get black screen when i try to set the frontViewController once...Here is the work that i have done
Actually everything was working fine just need another method to call
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if indexPath.row == 2{
if let temp = navcontroller{
self.revealViewController().pushFrontViewController(temp, animated: true)
}else{
println("navigation controller contains nil vaue")
}
}
}

currently thumbnails are being shown in UITableViewCell and upon tapping a cell, I want the image to be shown in foreground with a cross/X button on right top to dismiss the image and show tableView. I have the following code in didSelectRow:
let hoverImage = UIImageView()
hoverImage.image = UIImage(named: "splashpt")
hoverImage.contentMode = .scaleAspectFit
self.view.addSubview(hoverImage)
hoverImage.center = self.view.center
hoverImage.layer.zPosition = 5
self.view.bringSubview(toFront: hoverImage)
Still the image doesn't show up. The computation is hitting this section of the code because I'm able to debug and step through this part of the code. But nothing shows up on screen. I'm using the zPosition AND bringSubview(toFront:) and neither of the seem to work for my requirement. Any help would be greatly appreciated. Thank you.
This is a Demo table view.On tapping the table view cells a view is poped up with close button. And on pressing the close button the pop up view is closed.

I just started building an app and right now I am adding 2 Split View Controllers, in my Main.storyboard it looks like this image
I added the following code to my Master:
import UIKit
class ContactsMaster: UITableViewController {
var ContactsDetailController: ContactsDetail? = nil
var objects = [Any]()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
navigationItem.leftBarButtonItem = editButtonItem
let addButton = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(insertNewObject(_:)))
navigationItem.rightBarButtonItem = addButton
if let split = splitViewController {
let controllers = split.viewControllers
ContactsDetailController = (controllers[controllers.count-1] as! UINavigationController).topViewController as? ContactsDetail
}
}
override func viewWillAppear(_ animated: Bool) {
clearsSelectionOnViewWillAppear = splitViewController!.isCollapsed
super.viewWillAppear(animated)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#objc
func insertNewObject(_ sender: Any) {
objects.insert(NSDate(), at: 0)
let indexPath = IndexPath(row: 0, section: 0)
tableView.insertRows(at: [indexPath], with: .automatic)
}
// MARK: - Segues
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showContactDetail" {
if let indexPath = tableView.indexPathForSelectedRow {
let object = objects[indexPath.row] as! NSDate
let controller = (segue.destination as! UINavigationController).topViewController as! ContactsDetail
controller.detailItem = object
controller.navigationItem.leftBarButtonItem = splitViewController?.displayModeButtonItem
controller.navigationItem.leftItemsSupplementBackButton = true
}
}
}
// MARK: - Table View
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return objects.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let object = objects[indexPath.row] as! NSDate
cell.textLabel!.text = object.description
return cell
}
override func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
// Return false if you do not want the specified item to be editable.
return true
}
override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete {
objects.remove(at: indexPath.row)
tableView.deleteRows(at: [indexPath], with: .fade)
} else if editingStyle == .insert {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view.
}
}
}
And here is my Detail:
import UIKit
class ContactsDetail: UIViewController {
#IBOutlet weak var detailDescriptionLabel: UILabel!
func configureView() {
// Update the user interface for the detail item.
if let detail = detailItem {
if let label = detailDescriptionLabel {
label.text = detail.description
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
configureView()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
var detailItem: NSDate? {
didSet {
// Update the view.
configureView()
}
}
}
My problem is when I run my app and goto the Split View Controller and select an item in the Master, it does not goto the Detail, but instead replaces the master.
I have a sample app that is just the Split View Controller and I noticed in the App Delegate file of the sample app there is this code in the application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool method:
let splitViewController = window!.rootViewController as! UISplitViewController
let navigationController = splitViewController.viewControllers[splitViewController.viewControllers.count-1] as! UINavigationController
navigationController.topViewController!.navigationItem.leftBarButtonItem = splitViewController.displayModeButtonItem
splitViewController.delegate = self
And there is also this method:
func splitViewController(_ splitViewController: UISplitViewController, collapseSecondary secondaryViewController:UIViewController, onto primaryViewController:UIViewController) -> Bool {
guard let secondaryAsNavController = secondaryViewController as? UINavigationController else { return false }
guard let topAsDetailController = secondaryAsNavController.topViewController as? DetailViewController else { return false }
if topAsDetailController.detailItem == nil {
// Return true to indicate that we have handled the collapse by doing nothing; the secondary controller will be discarded.
return true
}
return false
}
My problem with this code is that my Split View Controller is not the inital controller and my problem with the splitViewController method, I have 2 split view controllers, I can only specificity 1 of them. How do I get this split view controller without making it the inital controller?
your master class must implement UISplitViewControllerDelegate.
so first thing you need to do :
class ContactsMaster: UITableViewController,UISplitViewControllerDelegate {
and override this function in your master:
func splitViewController(splitViewController: UISplitViewController, collapseSecondaryViewController secondaryViewController: UIViewController, ontoPrimaryViewController primaryViewController: UIViewController) -> Bool {
return true
}
then in viewDidLoad(master class) add following cods:
self.splitViewController!.delegate = self;
self.splitViewController!.preferredDisplayMode = UISplitViewControllerDisplayMode.AllVisible
self.extendedLayoutIncludesOpaqueBars = true
I think you skip many steps for configuring splitviewcontroller, if you want to understand all the way you can read one of many tutorials written for it, like:
http://nshipster.com/uisplitviewcontroller/
Did you by chance forget to set the ContactsDetail class for your Detail VC in your Storyboard?
I want to use a TableView for the detail side of a Master Detail app. I have started with the standard Master Detail project in Xcode, deleted the standard app that comes with it, deleted the standard UIView detail controller, added a TableView controller, added a TextView to the prototype cell for testing, and created a new segue to the new TableView. I subclassed UITableViewCell and created an outlet (detailTextView) from the TextView to the subclass (TableViewCell). Changed the class in DetailViewController.swift from UIViewController to UITableViewController. I am successfully passing a string stringForTextView = "String for TextView" from master to the detail. But I can't figure out how to display that string in the TextView. I tried to reference the TextView text in the detail view through the outlet (detailTextView.text) but got "Use of unresolved identifier detailTextView"
Any help will be greatly appreciated.
Relevant code is shown below.

DetailViewController is a UITableViewController, and you can't access the detailTextView in the tableView controller. You defined the outlet in the cell, and that is where you can access and configure the detailTextView.
It doesn't make any sense to have the DetailViewController as a UITableViewController, if what you really want is to configure the text view there. Then you should set it back to a UIViewController, and add the text view as a single UITextView to the view controllers view.
This link below shows how you can change text in a cell label even though the outlet to the textview is in the cell subclass. It shows this with a single TableView.
creating custom tableview cells in swift
In adapting the above approach for my test project, I didn't have to change the Master at all. In the Detail view, the configureView() doesn't do the main job of updating the TextView. That happens in cellForRowAtIndexPath -- second to the last function in detail view. Another difference is I could not, and did not need to, implement #IBOutlet var tableView: UITableView! -- because tableView was already available as a stored property. I also had to add overrride in a couple of places. Finally, in the TableViewCell class, I added an outlet linked to the content view of the TextView. The result is that the TextView text is getting updated.
TableViewCell.swift:
import UIKit
class TableViewCell: UITableViewCell {
#IBOutlet weak var detailTextView: UITextView!
#IBOutlet weak var detailContentView: UIView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
print ("awakeFromNib")
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
print("test")
}
}
DetailViewController.swift:
import UIKit
class DetailViewController: UITableViewController {
// #IBOutlet var tableView: UITableView! -- cannot override a stored property
var stringForTextView : String?
// Don't forget to enter this in IB also
let cellReuseIdentifier = "reuseIdentifier"
var detailItem: AnyObject? {
didSet {
// Update the view.
self.configureView()
}
}
func configureView() {
// Update the user interface for the detail item.
// stringForTextView
let printThis = stringForTextView! as String
print("\(printThis)")
// detailTextView.text = printThis
}
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
self.configureView()
}
// needed "override" here
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
// create a cell for each table view row
// needed "override" here
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell:TableViewCell = self.tableView.dequeueReusableCellWithIdentifier(cellReuseIdentifier) as! TableViewCell
cell.detailTextView.text = stringForTextView
print("cell.detailTextView.text: \(cell.detailTextView.text)")
print("row : \(indexPath.row)")
return cell

I am new to swift language and start to creating stub application having sliding menu. I used tutorial from http://www.appcoda.com/sidebar-menu-swift/ to create slide menu but want to create application which is dynamic not static as shown in example. I am facing problem in creating segue or doing navigation from the uitableviewcell to the respective uiviewcontrollers which is connected to respective uinavigationcontroller.
following is the code for sliding menu class:
MenuController.swift
import UIKit
class MenuController:UITableViewController
{
let menuControlList = ["Category 1", "Category 2", "Category 3", "Category 4"]
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// Return the number of sections.
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// Return the number of rows in the section.
return menuControlList.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! MenuTableCell
let row = indexPath.row
cell.menuCellText.text = menuControlList[row]
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print("row clicked :: ", indexPath.row)
switch indexPath.row
{
case 0:
var cat1View = Category1(nibName:"Category1", bundle:nil)
self.navigationController?.pushViewController(cat1View, animated: true)
print(indexPath.row)
break
case 1:
var cat2View = Category2(nibName:"Category2", bundle:nil)
self.navigationController?.pushViewController(cat2View, animated: true)
print(indexPath.row)
break
case 3:
var cat3View = Category3(nibName:"Category3", bundle:nil)
self.navigationController?.pushViewController(cat3View, animated: true)
print(indexPath.row)
break
case 4:
var cat4View = Category4(nibName:"Category4", bundle:nil)
self.navigationController?.pushViewController(cat4View, animated: true)
print(indexPath.row)
break
default:
return;
}
}
}
Following is the screenshot of my storyboard:
if i am doing any mistake in creating this please let me know and help me rectify it.
Following is the code of my category 1 class :
class Category1 :UIViewController
{
#IBOutlet var menuBtn: UIBarButtonItem!
override func viewDidLoad() {
super.viewDidLoad()
if self.revealViewController() != nil {
menuBtn.target = self.revealViewController()
menuBtn.action = "revealToggle:"
self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
EDIT:
Tried following solution:
let vc = storyboard.instantiateViewControllerWithIdentifier("Category1") as! Category1
presentViewController(vc, animated: true, completion: nil)
the above code directly opens up category 1 viewcontroller with slideup animation but it is not opening through the navigationcontroller attached with the respective viewcontroller.
if i use the following code:
let vc = storyboard.instantiateViewControllerWithIdentifier("Category1") as! Category1
self.revealViewController().setFrontViewController(vc, animated: true)
the above code also loads viewcontroller but the sliding menu doesnt slide back in?
First of all, give your Navigation View Controllers a storyboard ID, and not the actual view controllers. So for example, if Category1 is embedded in the Navigation Controller, then give the Navigation Controller a storyboard ID of Category1NavController for example. Then your code should be as follows:
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print("row clicked :: ", indexPath.row)
switch indexPath.row
{
case 0:
let navController1 = storyboard.instantiateViewControllerWithIdentifier("Category1NavController") as! UINavigationController
self.revealViewController().setFrontViewController(navController1, animated: true)
print(indexPath.row)
break
..........
// Handle other cases similarly here
case 1:
.....
case 2:
.....
default:
return;
}
self.revealViewController().setFrontViewPosition(FrontViewPosition.Left, animated: true)
}
You should also reset the Top View position after your switch statement ends. Here's how it should be (sorry again if syntax is not correct, please fix accordingly):
self.revealViewController().setFrontViewPosition(FrontViewPosition.Left, animated: true)
There must be a similar method to be called in Swift.
Hope this helps. Please pardon my SWIFT syntax and correct it if needed.
In my iOS 8 app I've got a custom ViewController which I present as Popover. This ViewController has a delegate, which get, and send to parent ViewController, the clicked index in popup. The problem is that I can't dismiss this Popover after selectRow.
Here's the code:
This is the method which I call when I want to show my Popup.
#IBAction func registerButtonAction(sender: UIButton) {
popup = self.storyboard!.instantiateViewControllerWithIdentifier("PopupViewController") as? PopupViewController
popup!.modalPresentationStyle = .Popover
popup!.preferredContentSize = CGSizeMake(100, 120)
let popoverMenuViewController = popup!.popoverPresentationController
popoverMenuViewController?.permittedArrowDirections = .Up
popoverMenuViewController?.delegate = self
popoverMenuViewController?.sourceView = sender
popoverMenuViewController?.sourceRect = CGRect(
x: sender.frame.size.width/2,
y: sender.frame.size.height/2,
width: 1,
height: 1)
popup!.delegate = self
presentViewController(
popup!,
animated: true,
completion: nil)
}
Here's PopupViewController code:
protocol PopupViewControllerDelegate
{
func rowClickedAtIndex(var index : Int)
}
class PopupViewController: MainViewController {
var delegate : PopupViewControllerDelegate?
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension PopupViewController:UITableViewDelegate{
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
var cell:PopupTableViewCell? = tableView.dequeueReusableCellWithIdentifier("PopupTableViewCell") as? PopupTableViewCell
if cell == nil {
cell = PopupTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "PopupTableViewCell")
}
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if (self.delegate != nil)
{
self.delegate!.rowClickedAtIndex(indexPath.row)
self.dismissViewControllerAnimated(true, completion: nil)
}
}
func numberOfSectionsInTableView(tableView: UITableView?) -> Int {
return 1
}
func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{
return 2
}
}
Thank you.
I solved by myself:
I checked that the problem wasn't that the popover wasn't dismissed, but it was dismissed but after different seconds.
So I put my dismiss call in the main thread and it worked perfectly. Here's the code:
extension WelcomeViewController: PopupViewControllerDelegate {
func rowClickedAtIndex(index: Int) {
dispatch_async(dispatch_get_main_queue(),{
self.dismissViewControllerAnimated(true, completion: nil)
println(index)
})
}
}
I want to thank you Frankie, who helped me in finding the solution, removing what shouldn't be the problem.
Move your dismissViewControllerAnimated(true, completion: nil) call into the delegate at the end of the clickedRowAtIndex method. In other words, the presenting view controller should call the dismissing, not the presented view controller.
Try this:
extension WelcomeViewController: PopupViewControllerDelegate {
func rowClickedAtIndex(index: Int) {
dismissViewControllerAnimated(true, completion: nil)
println(index)
}
}
