i just made one wrapper class for share helper my code is as follow.
let activityVC = UIActivityViewController(activityItems: [message], applicationActivities: nil)
activityVC.setValue(subject, forKey: "subject")
activityVC.completionWithItemsHandler = {(activityType: String!, completed:Bool, objects:[AnyObject]!, error:NSError!) in
}
fromVC.presentViewController(activityVC, animated: true, completion: nil)
problem starts here, UIActivityItemSource methods not being call
override func activityViewController(activityViewController: UIActivityViewController, itemForActivityType activityType: String) -> AnyObject? {
switch activityType
{
case UIActivityTypeMail:
return msg
case UIActivityTypeMessage:
return msg
case UIActivityTypePostToFacebook:
return msg
case UIActivityTypePostToTwitter:
return strTwitterShare
default:
return msg
}
}
thanks for help
It should work if you use let activityVC = UIActivityViewController(activityItems: [self], applicationActivities: nil)
... then your message is provided inside your itemForActivityType method.

I want to let the people login to the certain domain, but it always shows a error.
Cannot convert value of type 'String' to expected argument type 'Int').
how can I deal with it?
import UIKit
import FirebaseAuth
class ViewController: UIViewController {
#IBOutlet var emailTextField: UITextField!
#IBOutlet var passwordTextField: UITextField!
#IBAction func signUp(_ sender: Any) {
Auth.auth().createUser(withEmail: emailTextField.text!, password: passwordTextField.text!) { (result, error) in
if error != nil{
print(error)
}else{
self.performSegue(withIdentifier: "createdUser", sender: self)
}
}
}
#IBAction func signIn(_ sender: Any) {
Auth.auth().signIn(withEmail: emailTextField.text!, password: passwordTextField.text!) { (result, error) in
if error != nil{
print(error)
}else{
var hi = self.emailTextField.text
if hi?.suffix("#hkugac.edu.hk"){ //error here
self.performSegue(withIdentifier: "logged", sender: self)
}
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
}
Try using the hasSuffix method. https://developer.apple.com/documentation/swift/string/1541149-hassuffix
var hi = self.emailTextField.text
if let mail = hi, mail.haSuffix("#hkugac.edu.hk")
{
self.performSegue(withIdentifier: "logged", sender: self)
}
else
{
// Dome some error handling here.
}
Also, I think it would be better to check the mail before you call the signIn function.
I am trying to download an image from my web server, using Xcode 8 and Swift 3. It looks like this. The request returns nil. Any suggestions why?
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var view1: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func load(_ sender: UIButton) {
let url = URL(string:"http://www.example.com/folder2/pic3-1.jpg")
let task = URLSession.shared.dataTask(with: url!) { data, response,
error in
guard let data = data, error == nil else { return }
DispatchQueue.main.sync() {
self.view1.image = UIImage(data: data)
}
}
task.resume()
}
#IBAction func reset(_ sender: UIButton) {
self.view1.image="blankU.png"
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
Any idea why the image is returning nil from the server?
The Xcode8, Swift3 coding is okay. The server is blocked.
I want to call a method by using NSNotificationCenter .They do not call in Swift 2.0. I am newer in Swift . Please help . Any help would be apperciated.
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let landingView = NewsViewController(nibName : "NewsViewController", bundle: nil)
NSNotificationCenter.defaultCenter().postNotificationName("NotificationIdentifier", object: nil)
self.navigationController?.pushViewController(landingView, animated: true)
}
In my News Controller
override func viewDidLoad() {
super.viewDidLoad()
NSNotificationCenter.defaultCenter().addObserver(self, selector: "methodOfReceivedNotification:", name:"NotificationIdentifier", object: nil)
}
func methodOfReceivedNotification(notification: NSNotification){
}
override func viewWillDisappear(animated: Bool) {
NSNotificationCenter.defaultCenter().removeObserver(self, name: "NotificationIdentifier", object: nil)
}
You called this method
NSNotificationCenter.defaultCenter().postNotificationName("NotificationIdentifier", object: nil)
before your observer's created. So please post your notification after this method self.navigationController?.pushViewController(landingView, animated: true) completed. You can refer this post:
Completion handler for UINavigationController "pushViewController:animated"?
Hope that helps.
When I click on either of my IAPS, a message appears saying the IAP was already purchased (which is not the case) and will be restored for free, then nothing happens, the IAP doesn't execute.
Here is what I get in my console:
No Value.
IAP is enabled, loading...
true
Product Request
Product Added
IAP id
Remove Ads
Removes ads from the app.

I found the solution !
Delete
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
everywhere you have it and put it once (ONLY ONCE) in a place where it will be executed each time your app boots up ( I put it in viewDidLoad()).
This will check for all unfinished transactions and terminate them once the app has loaded, thus removing any possible errors before your users triggers an IAP.
(If this answer, or this question helped you, don't forget to upvote ;))
P.S.: Also, this wasn't my issue, but make sure to finishTransaction() for each PurchaseState like here:
func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
print("Add Payment")
for transaction:AnyObject in transactions{
let trans = transaction as! SKPaymentTransaction
print(trans.error)
switch trans.transactionState{
case .Purchased:
print("IAP unlocked")
print(p.productIdentifier)
let prodID = p.productIdentifier as String
switch prodID{
case "IAP id":
print("Keep on")
keepOn()
default:
print("IAP not setup")
}
queue.finishTransaction(trans)
break
case .Failed:
print ("Buy error")
queue.finishTransaction(trans)
break
default:
print("default: Error")
break
}
}
}
Never forget this:
queue.finishTransaction(trans)
The line below, at SQLHandler.translateQuery("Do mysql stuff"), is throwing the error: '(String) -> String' is not convertible to 'SQLHandler'. Why is it doing this? Thank you in advance.
Code 1 (Used wherever and whenever needed)
var query: String = "mysql stuff"
SQLHandler.sendQuery(SQLHandler.translateQuery("domain and \(query)"))
Code 2, SQLHandler.swift (Called whenever needed)
import Foundation
class SQLHandler {
func translateQuery(queryToTranslate: String) -> String{
println(queryToTranslate)
return queryToTranslate.stringByReplacingOccurrencesOfString(" ", withString: "_", options: NSStringCompareOptions.LiteralSearch, range: nil)
}
func sendQuery(query: String){
println(query)
let url = NSURL(string: "url and query goes here")
let task = NSURLSession.sharedSession().dataTaskWithURL(url!, completionHandler: { (data, response, error) -> Void in })
task.resume()
}
}
You are calling an instance method on the class itself.
Either create an instance and call the method:
var sqlHandler = SQLHandler()
sqlHandler.translateQuery("domain and \(query)")
or define the methods as class methods :
class func translateQuery(queryToTranslate: String) -> String ...
class func sendQuery(query: String) ...
