I am trying to show a UIAlertController which will display my terms of service. I can not simply paste the terms of service into the message body, what would be the best way to achieve this. I am also only calling it once on apps first launch.
func agree(){
let alert = UIAlertController(title: "Terms of Service", message:"", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "Agree", style: .default, handler: { (action: UIAlertAction) in
print("OK")
}))
self.present(alert, animated: true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
if UserDefaults.standard.bool(forKey: "Walkthrough") {
print("already shown")
// Terms have been accepted, proceed as normal
} else {
agree()
UserDefaults.standard.set(true, forKey: "Walkthrough")
}
}

I have login alert connected to UIViewController called Intro the alert show up in home screen and in all tabBar views when the user click in one of them, the alert prevent user from using the app unless he sign up. I want to stop the alert from showing because I'm implementing it somewhere else.
I tried to delete/comment the code but that resulted in a lot of errors showing
// MARK: - SHOW LOGIN ALERT
func showLoginAlert(_ mess:String) {
let alert = UIAlertController(title: APP_NAME,
message: mess,
preferredStyle: .alert)
let ok = UIAlertAction(title: "Login", style: .default, handler: { (action) -> Void in
let aVC = self.storyboard?.instantiateViewController(withIdentifier: "Intro") as! Intro
self.present(aVC, animated: true, completion: nil)
})
alert.addAction(ok)
let cancel = UIAlertAction(title: "Cancel", style: .destructive, handler: { (action) -> Void in })
alert.addAction(cancel)
present(alert, animated: true, completion: nil)
}
// MARK: - FIRE A SIMPLE ALERT
func simpleAlert(_ mess:String) {
let alert = UIAlertController(title: APP_NAME,
message: mess, preferredStyle: .alert)
let ok = UIAlertAction(title: "OK", style: .default, handler: { (action) -> Void in })
alert.addAction(ok)
present(alert, animated: true, completion: nil)
}
Why is the completion not working ?
After the alert appears, its not transitioning to the other viewController
self.present(self.alertController2, animated: true, completion: {
self.performSegue(withIdentifier:"goToLogin", sender: self)
})
Self.present using for add this action into view . You need to add this code into your handler handler mean It means what will I do when you click OK
let alertbutton = UIAlertAction(title: "OK", style: .destructive, handler: {
(UIAlertAction) in
self.performSegue(withIdentifier: "your id", sender: self)
})
Complete example :
let alert = UIAlertController(title: "Its empty", message: "Going another view", preferredStyle: .alert)
let alertaction = UIAlertAction(title: "OK", style: .destructive, handler: { (UIAlertAction) in
self.performSegue(withIdentifier: "your segue id", sender: self)
})
alert.addAction(alertaction)
self.present(alert, animated: true, completion: nil)
You should write code first move into new view code run then show alert in main thread for displaying alert.
DispatchQueue.main.async {
// AlertView.showAlert(title: Messages.Network.title, message: Messages.Network.message)
// }
I'm creating an alert but I can't dismiss it when the user presses OK. I'm getting the following error:
2017-12-28 07:03:50.301947-0400 Prestamo[691:215874] API error:

I was searching everywhere on the Internet but I couldn't find anything that helped me.
override func viewDidAppear(_ animated: Bool) {
createAlert(title: "Licencia2", message: "En el momento no tienes una licencia válida!")
}
func createAlert (title:String, message:String) {
let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: {(action) in
alert.dismiss(animated: false, completion: nil)
}))
self.present(alert, animated: false, completion: nil)
}
Any ideas would be appreciated
You don't have to dismiss alert controller. It will automatically dismiss after the action handler has been called. Just remove the dismiss line.
let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: {(action) in
}))
self.present(alert, animated: false, completion: nil)
Please note the difference with this answer and you code.
You didn't invoked super.viewDidAppear(animated) and this causes problems.
Below code (this is all I used) works for me without problems (I've test it):
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
createAlert(title: "My test", message: "THis should work ok")
}
func createAlert (title:String, message:String) {
let alert = UIAlertController(title: title, message: message, preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "Ok", style: .default) {
action in
NSLog("it is working ok");
})
present(alert, animated: true)
}
}
Im having a problem where after I broadcast my screen live, I then try to record the screen but it doesn't work. Same thing happens when I record my screen and then I try to broadcast the screen live. Im not trying to do them together btw. This is after one is done and I try to use the other one. Let me know if you need to see code or more info. Im in Swift 3 and using the new replay kit framework. Thanks!
EDIT: THIS IS THE CODE IM USING
//LIVE STREAM REPLAYKIT=====================================================================
func broadcastActivityViewController(_ broadcastAVC: RPBroadcastActivityViewController, didFinishWith broadcastController: RPBroadcastController?, error: Error?) {
print("=====hello delegate \(broadcastController?.broadcastURL) (error)")
self.broadcastController = broadcastController
self.broadcastController?.delegate = self
broadcastAVC.dismiss(animated: true) {
self.broadcastController?.startBroadcast(handler: { error in
print("start broadcast \(error)")
print("\(broadcastController?.broadcastExtensionBundleID)")
print("==url=\(broadcastController?.broadcastURL)")
print("==serviceInfo=\(broadcastController?.serviceInfo)")
//This is called when the broadcast is live
})
}
}
func broadcastController(_ broadcastController: RPBroadcastController, didFinishWithError error: Error?) {
print("broadcastController====delegate")
let alert = UIAlertController(title: "Alert", message: "There was an error broadcasting your screen. Please try again", preferredStyle: UIAlertControllerStyle.alert)
// show the alert
self.view!.window?.rootViewController!.present(alert, animated: true, completion: nil)
alert.addAction(UIAlertAction(title: "Okay", style: UIAlertActionStyle.destructive, handler: { action in
// add action
}))
}
func broadcastController(_ broadcastController: RPBroadcastController, didUpdateServiceInfo serviceInfo: [String : NSCoding & NSObjectProtocol]) {
print("broadcastController====didUpdateServiceInfo")
}

//if iphone or ipad doesnt support replaykit

self.view!.window?.rootViewController!.present(alert, animated: true, completion: nil)
alert.addAction(UIAlertAction(title: "Try Again!", style: UIAlertActionStyle.destructive, handler: { action in
// add action
}))
}
}
func stopRecording() {
let sharedRecorder = RPScreenRecorder.shared()
sharedRecorder.stopRecording(handler: { (previewViewController: RPPreviewViewController?, error) in
if previewViewController != nil {
print("stopped recording")
previewViewController!.previewControllerDelegate = self

})
alertController.addAction(viewAction)
self.previewViewController = previewViewController!
self.previewViewController.modalPresentationStyle = UIModalPresentationStyle.fullScreen
self.view?.window?.rootViewController!.present(alertController, animated: true, completion: nil)
}
else {

I believe that this is a bug in ReplayKit, I'm not sure if it has been resolved as of 10.1 or not, but it is worth trying the 10.1 beta to see if it solves your issue.
Opening the UIAlertController on button click, the action is going to open but main issue is the UIAlertAction methods are not performed on its click. Here is Code block :
class HomeViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// getData()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//menuBtn is the button
#IBAction func menuBtn(sender: UIButton) {
let optionMenu = UIAlertController(title: nil, message: nil, preferredStyle: .ActionSheet)
let orders = UIAlertAction(title: "Orders", style: .Default, handler: { (alert: UIAlertAction!) -> Void in
let alertViewController = self.storyboard?.instantiateViewControllerWithIdentifier("OrdersViewController") as! OrdersViewController
self.presentViewController(alertViewController, animated: true, completion: nil)
})
let about = UIAlertAction(title: "About", style: .Default, handler: {(alert: UIAlertAction!) -> Void in
let aboutObject = self.storyboard?.instantiateViewControllerWithIdentifier("AboutViewController") as! AboutViewController
self.presentViewController(aboutObject, animated: true, completion: nil)
})
let contactUs = UIAlertAction(title: "Contact Us", style: .Default, handler: {(alert: UIAlertAction!) -> Void in
let alertViewController = self.storyboard?.instantiateViewControllerWithIdentifier("ContactViewController") as! ContactViewController
self.presentViewController(alertViewController, animated: true, completion: nil)
})
let login = UIAlertAction(title: "LogIn", style: .Default, handler: {(alert: UIAlertAction!) -> Void in
let alertViewController = self.storyboard?.instantiateViewControllerWithIdentifier("LoginViewController") as! LoginViewController
self.presentViewController(alertViewController, animated: true, completion: nil)
})
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
optionMenu.addAction(orders)
optionMenu.addAction(about)
optionMenu.addAction(contactUs)
optionMenu.addAction(login)
optionMenu.addAction(cancelAction)
self.presentViewController(optionMenu, animated: true, completion: nil)
}
This is code is working fine, I have checked it's opening new viewController as well.
Cross check points:
Controller class and stroybaord are connected
Storyboard ID has been assigned
IBAction must be connected to IBOutlet
On the Button click Action you have to write code.. Try This code.
let alert = UIAlertController(title: "Saved", message: "Selected Frame is Saved", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "Ok", style:.Default , handler: { (UIAlertAction) in
}))
//Add action like this
self.presentViewController(alert, animated: true, completion: nil)
Still need any help feel free to ask.
First of all check if the button action is touch up inside. Make the button action as touch up inside. Below code works for me. Hope this works for you as well. Change the action title according to your need.
#IBAction func menuBtn(sender: AnyObject) {
let actionSheet = UIAlertController()
let criticalAction = UIAlertAction(title : "CRITICAL" , style : UIAlertActionStyle.Default){
(action) in
//This section will be executed when the buttons are pressed
//Do your work here.
debugPrint("CRITICAL")
}
let highAction = UIAlertAction(title : "HIGH" , style : UIAlertActionStyle.Default){
(action) in
//This section will be executed when the buttons are pressed
//Do your work here.
debugPrint("HIGH")
}
actionSheet.addAction(criticalAction)
actionSheet.addAction(highAction)
self.presentViewController(actionSheet, animated: true, completion: nil)
}
