I want to show my custom view when there is no network connection.
Something like this:
I have a ViewController inside a NavigationController
in AppDelegate I write like this:
var statusView: NetworkStatusView?
...
func showNetworkStatusView() {
if statusView == nil {
statusView = NetworkStatusView()
if let statusView = statusView {
let screenSize = UIScreen.mainScreen().bounds
statusView.frame = CGRect(x: 0, y: 0, width: screenSize.width, height: 60)
statusView.hidden = false
if let rootViewController = window?.rootViewController {
rootViewController.view.addSubview(statusView)
}
}
}
}
and In my ViewController, I call like this:
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.showNetworkStatusView()
But it doesn't show my custom view. I've also try view.addSubView(statusView) in my ViewController, but doesn't work also. I make sure that the function is called, because I debugged.
Here is my NetworkStatusView:
import UIKit
class NetworkStatusView: UIView {
#IBOutlet var contentView: UIView!
#IBOutlet weak var statusImageView: UIImageView!
#IBOutlet weak var statusLabel: UILabel!
required override init(frame: CGRect) {
super.init(frame: frame)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
initSubviews()
}
func initSubviews() {
let nib = UINib(nibName: "NetworkStatusView", bundle: nil)
nib.instantiateWithOwner(self, options: nil)
contentView.frame = bounds
addSubview(contentView)
}
}

I am using two xib files of UIView. I want to show Custominfoview on pressing button from first xib view which is FirstView. I am little confused here how to do that. My codes is below please tell me how to do that. I have searched a lot but nothing found. I have attached a picture in link which is I exactly want.
class CustominfoView: UIView {
#IBOutlet var mainCustomView: UIView!
#IBOutlet weak var infotextLbl: UILabel!
// MARK:-
// MARK:- Methods
// MARK: UIView Methods
required init(coder aDecoder : NSCoder) {
super.init(coder :aDecoder)!
setup()
}
override init(frame : CGRect) {
super.init(frame: frame)
setup()
}
func setup() {
let view = loadViewFromXib()
view.frame = bounds
// view.autoresizingMask = UIViewAutoresizing.flexibleWidth | UIViewAutoresizing.flexibleHeight
view.layer.cornerRadius = 12
view.layer.borderColor = UIColor.red.cgColor
view.layer.borderWidth = 2
addSubview(view)
}
func loadViewFromXib() -> UIView {
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: "CustominfoView", bundle: bundle)
let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
return view
}
}
class FirstView: UIView {
#IBOutlet var mainCustomView: UIView!
#IBOutlet weak var infotextLbl: UILabel!
// MARK:-
// MARK:- Methods
// MARK: UIView Methods
required init(coder aDecoder : NSCoder) {
super.init(coder :aDecoder)!
setup()
}
override init(frame : CGRect) {
super.init(frame: frame)
setup()
}
func setup() {
let view = loadViewFromXib()
view.frame = bounds
// view.autoresizingMask = UIViewAutoresizing.flexibleWidth | UIViewAutoresizing.flexibleHeight
view.layer.cornerRadius = 12
view.layer.borderColor = UIColor.red.cgColor
view.layer.borderWidth = 2
addSubview(view)
}
func loadViewFromXib() -> UIView {
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: "CustominfoView", bundle: bundle)
let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
return view
}
#IBAction func infoBtnpressed(_ sender: UIButton) {
print("Pressed")
}
}
}
Just add customInfoView as a subview on top of the first view using addSubview.
(button pressed)
let customInfoView = CustomInfoView()
self.addSubview(customInfoView)
And then when you need to dismiss it simply remove it from the parent.
You can do something like this :
#IBAction func infoBtnpressed(_ sender: UIButton) {
print("Pressed")
let customInfoView = CustomInfoView(frame: CGRect(x: 100, y: 100, width: 200, height: 200) )
self.addSubView(customInfoView)
}
In CGRect pass the frame value as desired. Also you should declare the customInfoView as global so that you can remove it easily.
This AssetRFPViewController class call a custom view(AssetBasicInfo) in viewDidLoad, if a pass "Hello" its ok but when i pass object to custom view(AssetBasicInfo) its not taken, How can i design a custom view class so its catch object
class AssetRFPViewController: UIViewController
{
var asset:Asset = Asset()
override func viewDidLoad() {
let customView = AssetBasicInfo(frame: self.topHeaderView.bounds)
customView.assetNameValLbl.text = "Hello" // ok
customView.assetObj = self.asset // not ok, passing object
self.topHeaderView.addSubview(customView)
}
}
Now my custom class look like this,
class AssetBasicInfo: UIView {
#IBOutlet var containerView: UIView!
var assetObj:Asset = Asset() // i want value in this object "assetObj"
#IBOutlet var assetNameValLbl: UILabel!
override init(frame: CGRect) {
super.init(frame: frame)
print(frame.size.width)
print(frame.size.height)
commonInit()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder : aDecoder)
commonInit()
}
private func commonInit(){
Bundle.main.loadNibNamed("HeaderViewXIB", owner: self, options: nil)
self.addSubview(containerView)
self.containerView.frame = self.frame
containerView.autoresizingMask = [.flexibleHeight, .flexibleWidth]
self.assetNameValLbl.text = assetObj.name // not setting value
print("screenName" , screenName)
}
}
I have created a custom view from xib(freeform) in which there are two button (Login and cancel) and i have present it at a view according to some condition. Custom view get present on another view nicely but the button(Login an cancel) not getting any touch event.
Code of custom class and init method:
import UIKit
class customAlertView: UIView {
#IBOutlet weak var messageLabel: UILabel!
#IBOutlet weak var loginButton : UIButton!
#IBOutlet weak var cancelButton: UIButton!
var view : UIView!
override init(frame: CGRect) {
super.init(frame: frame)
view = setUpFromXib()
view.frame = frame
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
func setUpFromXib() -> UIView {
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "customAlertView", bundle: bundle)
let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
addSubview(view)
translatesAutoresizingMaskIntoConstraints = true
return view
}
#IBAction func loginButtonAction(sender: AnyObject) {
}
#IBAction func cancelButtonAction(sender: AnyObject) {
}
}
This is the block of code from where i have add the custom view as a subview.
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if Reachability.isConnectedToNetwork() {
categoryObj = categoryArray .objectAtIndex(indexPath.row) as! TECategoryDetails
if categoryObj.categoryType == "premium" {
let screen = UIScreen.mainScreen().bounds
customView = customAlertView.init(frame: CGRect(origin: CGPoint(x: 0,y: 80), size: CGSize(width: screen.width, height: screen.height/3)))
self.view .addSubview(customView)
}
else{
watchAllFlag = false
self.performSegueWithIdentifier("Episode", sender: self)
}
}
else {
self.showAlertPopUp()
}
}
You can also do like this way.
import UIKit
class customAlertView: UIView {
#IBOutlet weak var messageLabel: UILabel!
#IBOutlet weak var loginButton : UIButton!
#IBOutlet weak var cancelButton: UIButton!
var view : UIView!
override init(frame: CGRect) {
super.init(frame: frame)
view = setUpFromXib()
view.frame = frame
loginButton.addTarget(self, action: Selector(“loginButtonAction:”), forControlEvents: .TouchUpInside)
cancelButton.addTarget(self, action: Selector(“cancelButtonAction:”), forControlEvents: .TouchUpInside)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
func setUpFromXib() -> UIView {
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "customAlertView", bundle: bundle)
let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
addSubview(view)
translatesAutoresizingMaskIntoConstraints = true
return view
}
func loginButtonAction(sender: AnyObject) {
}
func cancelButtonAction(sender: AnyObject) {
}
}
Check it, its working:
ViewController.swift:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
#IBAction func displayAlertBtnTapped(sender: AnyObject) {
let screen = UIScreen.mainScreen().bounds
let customView = CustomAlertView.init(frame: CGRect(origin: CGPoint(x: 0,y: 80), size: CGSize(width: screen.width, height: screen.height/3)))
self.view .addSubview(customView)
}
}
CustomAlertView.swift:
import UIKit
class CustomAlertView: UIView {
#IBOutlet weak var loginButton : UIButton!
#IBOutlet weak var cancelButton: UIButton!
var view : UIView!
override init(frame: CGRect) {
super.init(frame: frame)
view = setUpFromXib()
view.frame = frame
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
func setUpFromXib() -> UIView {
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "CustomAlertView", bundle: bundle)
let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
addSubview(view)
translatesAutoresizingMaskIntoConstraints = true
return view
}
#IBAction func loginButtonAction(sender: AnyObject) {
print("Login button clicked");
}
#IBAction func cancelButtonAction(sender: AnyObject) {
print("Cancel button clicked");
}
}

I'm very new to swift so sorry if this is a basic question or I'm doing something terribly wrong. I've been having some issues trying to add a subview when touching a row on a tableview and have been working off of this page: http://myxcode.net/2015/11/07/adding-a-subview-using-a-xib-and-storyboard/
Here's the relevant code I have so far (I removed some of the tableview logic because that works fine):
Subview Class
class ConfirmTeamView: UIView, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var teamListTableView2: UITableView!
#IBOutlet weak var confirmButton2: UIButton!
#IBOutlet weak var cancelButton2: UIButton!
var playerList: [Player]?
var view: UIView!
init(pList: [Player]) {
self.playerList = pList
super.init(frame: CGRectMake(20, 100, 385, 339))
setup()
teamListTableView2.delegate = self
teamListTableView2.dataSource = self
let playerListTableCellNib = UINib(nibName: "PlayerListTableViewCell", bundle: nil)
teamListTableView2.registerNib(playerListTableCellNib, forCellReuseIdentifier: "PlayerListTableViewCell")
}
required init?(coder aDecoder: NSCoder) {
self.playerList = nil
super.init(coder: aDecoder)
setup()
}
func setup() {
view = loadViewFromNib()
view.frame = bounds
view.autoresizingMask = [UIViewAutoresizing.FlexibleHeight,UIViewAutoresizing.FlexibleWidth]
addSubview(view)
}
func loadViewFromNib () -> UIView
{
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "ConfirmTeamView", bundle: bundle)
//this line I think is causing a stack overflow, any idea why?
let thisview = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
return thisview
}
}
and then in my viewController (I again removed some tableview methods for ease of reading):
class ChooseExistingTeamViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var TeamListTableView: UITableView!
var existingTeamsArray = [Team]()
var confirmTeamUI : ConfirmTeamView!
override func viewDidLoad() {
super.viewDidLoad()
TeamListTableView.delegate = self
TeamListTableView.dataSource = self
let testPlayer1 = Player(name: "John", number: 24)
let testPlayer2 = Player(name: "Smith", number: 50)
let testTeam = Team(name: "myTeam", players: [testPlayer1, testPlayer2])
existingTeamsList = [testTeam]
}
override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() }
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
// This is where I load the subview
TeamListTableView.userInteractionEnabled = false
let selectedTeam = existingTeamsList[indexPath.row]
let confirmTeamUI = ConfirmTeamView(pList: selectedTeam.players)
confirmTeamUI.cancelButton2.addTarget(self, action: "cancelPressed:", forControlEvents: UIControlEvents.TouchUpInside)
let viewWidth = self.view.frame.width
let xWidth = viewWidth - 40
let yHeight = 200
confirmTeamUI.frame = CGRect(x: 20, y: 100, width: Int(xWidth), height: yHeight)
self.view.addSubview(confirmTeamUI)
}
func cancelPressed(sender: UIButton) {
// self.confirmTeamUI.view.removeFromSuperview() [This line throws an exception for unwrapping an optional value]
if self.confirmTeamUI != nil { self.confirmTeamUI.removeFromSuperview() }
else { print("Confirm Team is nil") }
// pressing the cancel button runs the else case
}
Any advice would be very appreciated and please let me know if you need more!
I have created a custom UIView in xib with class InfoPopUpView. I add it to my viewController. It works well and the Custom Class xib is set in the File's Owner.
I can set the titleLbl variable in my first viewcontroller no problem.
My problem appears when I in another viewcontroller want to use the InfoPopUpView again but with a different title...
The title does not change/update. It is as if InfoPopUpView remembers the last title I set and dont care for changing it..
How can I initialise? the titleLbl variable in the InfoPopUpView Class so that I can change it later?
Any help is very much appreciated - thank you !
ViewController
var popUpView: InfoPopUpView!
popUpView = InfoPopUpView(frame: CGRectMake(0, 0, 300, 268))
popUpView.titleLbl.text = "MyFirstTitle"

Custom Class
class InfoPopUpView: UIView {
var view: UIView!
#IBOutlet weak var okBtn: UIButton!
#IBOutlet weak var titleLbl: UILabel!
#IBOutlet weak var textView: UITextView!
