UIAlertView first deprecated IOS 9

Question

I have tried several ways to use UIAlertController,instead of UIAlertView. I tried several ways but I cannot make the alert action work. Here is my code that works fine in IOS 8 and IOS 9 but is showing up with deprecated flags. I tried the elegant suggestion below but I can't make it function in this context. I need to submit my app and this is the last thing to address. Thank You for any further suggestions. I am a newbie.

#pragma mark - BUTTONS ================================
- (IBAction)showModesAction:(id)sender {
NSLog(@"iapMade: %d", iapMade3);

// IAP MADE ! ===========================================
if (!iapMade3) {

    //start game here
    gamePlaysCount++;
    [[NSUserDefaults standardUserDefaults]setInteger:gamePlaysCount forKey:@"gamePlaysCount"];
    NSLog(@"playsCount: %ld", (long)gamePlaysCount);

    if (gamePlaysCount >= 4) {
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"
                                                     message: THREE_PLAYS_LIMIT_MESSAGE

    } else {
        if (gamePlaysCount == 1)  {

                [alert show];
            }

UIAlertView is deprecated in IOS 9 and we have to use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead. However, the alert does not show when I use UIAlertController methods. I tried the solution below, but still the alert view does not show.. Thank you.. — Bux, Sep 21 '15 at 11:54
Okay. Can you show what you have done and that doesn't work ? — Moumou, Sep 21 '15 at 12:00
After presenting you are calling [self dismissViewControllerAnimated:true completion:nil]; which will dismiss alert controller — Adnan Aftab, Sep 22 '15 at 20:39
Yes.. I pasted the old code and pressed the tab button while editing message. I am new to Stack ... I still cannot get my code to work correctly with the UIAlertController class. My Complete code is: — Bux, Sep 23 '15 at 08:58
This is an important question in the sense that UIAlertController is pretty new and many developers will be worried about the deprecation. The unreasonable down votes have bad effect on a valid question. Those who down voted the question should have changed their vote after the edit. But then,"down vote trolls" who get a badge for their down vote do not do this anyway. The SO moderators should have a way to fix it. — Totoro, Dec 17 '15 at 01:29

From iOS8 Apple provide new UIAlertController class which you can use instead of UIAlertView which is now deprecated, it is also stated in deprecation message:

UIAlertView is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead

So you should use something like this

UIAlertController * alert = [UIAlertController
                alertControllerWithTitle:@"Title"
                                 message:@"Message"
                          preferredStyle:UIAlertControllerStyleAlert];



UIAlertAction* yesButton = [UIAlertAction
                    actionWithTitle:@"Yes, please"
                              style:UIAlertActionStyleDefault
                            handler:^(UIAlertAction * action) {
                                //Handle your yes please button action here
                            }];

UIAlertAction* noButton = [UIAlertAction
                        actionWithTitle:@"No, thanks"
                                  style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action) {
                                   //Handle no, thanks button                
                                }];

[alert addAction:yesButton];
[alert addAction:noButton];

[self presentViewController:alert animated:YES completion:nil];

Thank you for your fast reply.. I tried this, but the alert view does not show.. Nor does it when I add my yes please action. – Bux Sep 21 '15 at 11:56

Can you show me your code, because its working fine for me, make sure you are executing this code on main thread – Adnan Aftab Sep 21 '15 at 12:25
can you add your code inside question, that would be better every one can see that – Adnan Aftab Sep 21 '15 at 12:49
Hi, I added my complete code that works in IOS8 and IOS9, but is flagged deprecated. I tried several ways to implement your code but the alert does not show, and the action to open the store ViewController, will not function. Thank you for your help. – Bux Sep 23 '15 at 09:16
I think it's better to remove this line `[alert dismissViewControllerAnimated:YES completion:nil];` from the actions handlers, because the alert hides automatically without this code. Moreover, one can mistakenly put code in the completion block which will not be executed. Cheers :) – stellz Jan 18 '16 at 11:02
But In older UIAlertView I can show them in whatever place I wish to show, But Here I need a UIViewController to display the alert – vignesh kumar Mar 17 '16 at 17:38
@vignesh kumar if you want to use the new theme outside of a view controller use: UIApplication.sharedApplication().keyWindow?.rootViewController?.presentViewController(...) – Ali Beadle May 30 '16 at 13:11
@AliBeadle Thanks for the reply.just asking as I am handling an old project in which they show uialert from uitableviewcell (even thought it is bad way) – vignesh kumar May 31 '16 at 05:09

//Calling     
[self showMessage:@"There is no internet connection for this device"
                    withTitle:@"Error"];

//Method

-(void)showMessage:(NSString*)message withTitle:(NSString *)title
{

 UIAlertController * alert=   [UIAlertController
                                  alertControllerWithTitle:title
                                  message:message
                                  preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

        //do something when click button
    }];
    [alert addAction:okAction];
    UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
    [vc presentViewController:alert animated:YES completion:nil];
}

If you want to use this alert in NSObject class you should use like:

-(void)showMessage:(NSString*)message withTitle:(NSString *)title{
dispatch_async(dispatch_get_main_queue(), ^{
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
    [alertController addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

    }]];

    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:alertController animated:YES completion:^{
    }];
});
}

Swift version of new implementation is :

 let alert = UIAlertController(title: "Oops!", message:"your message", preferredStyle: .Alert)
 alert.addAction(UIAlertAction(title: "Okay.", style: .Default) { _ in })
 self.presentViewController(alert, animated: true){}

Assuming self is a UIViewController:

func displayAlert() {
    let alert = UIAlertController(title: "Test",
                                  message: "I am a modal alert",
                                  preferredStyle: .alert)
    let defaultButton = UIAlertAction(title: "OK",
                                      style: .default) {(_) in
        // your defaultButton action goes here
    }
    
    alert.addAction(defaultButton)
    present(alert, animated: true) { 
        // completion goes here
    }

A view has no business in doing, well, the business logic. Rethink your architecture so that a controller presents views (MVVM or MVC) – SwiftArchitect Apr 14 '17 at 19:21

Make UIAlertController+AlertController Category as:

UIAlertController+AlertController.h

typedef void (^UIAlertCompletionBlock) (UIAlertController *alertViewController, NSInteger buttonIndex);

@interface UIAlertController (AlertController)

                  WithTitle:(NSString *)title

          otherButtonTitles:(NSString *)otherButtonTitle
                   tapBlock:(UIAlertCompletionBlock)tapBlock;
@end

UIAlertController+AlertController.m

@implementation UIAlertController (NTAlertController)

                                           tapBlock(alertController, ALERTACTION_CANCEL); // CANCEL BUTTON CALL BACK ACTION
                                       }];
        [alertController addAction:cancelButton];

    }

    if(otherButtonTitle != nil) {

        UIAlertAction *otherButton = [UIAlertAction
                                   actionWithTitle:otherButtonTitle
                                   style:UIAlertActionStyleDefault
                                   handler:^(UIAlertAction *action)
                                   {
                                       tapBlock(alertController, ALERTACTION_OTHER); // OTHER BUTTON CALL BACK ACTION
                                   }];

        [alertController addAction:otherButton];
    }

    [controller presentViewController:alertController animated:YES completion:nil];

    return alertController;
}

@end

in your ViewController.m

[UIAlertController showAlertIn:self WithTitle:@"" message:@"" cancelButtonTitle:@"Cancel" otherButtonTitles:@"Other" tapBlock:^(UIAlertController *alertController, NSInteger index){

 if(index == ALERTACTION_CANCEL){

 // CANCEL BUTTON ACTION
 }else
if(index == ALERTACTION_OTHER){

 // OTHER BUTTON ACTION
 }

 [alertController dismissViewControllerAnimated:YES completion:nil];

 }];

NOTE: If you want to add more than two buttons then add another more UIAlertAction to the UIAlertController.

Use UIAlertController instead of UIAlertView

-(void)showMessage:(NSString*)message withTitle:(NSString *)title
{
UIAlertController * alert=   [UIAlertController
                              alertControllerWithTitle:title
                              message:message
                              preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

    //do something when click button
}];
[alert addAction:okAction];
UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
[vc presentViewController:alert animated:YES completion:nil];
}

I tried the above methods, and no one can show the alert view, only when I put the presentViewController: method in a dispatch_async sentence:

dispatch_async(dispatch_get_main_queue(), ^ { [self presentViewController:alert animated:YES completion:nil]; });

Refer to Alternative to UIAlertView for iOS 9?.

Check this:

    UIAlertAction *camera =[UIAlertAction actionWithTitle:@"camera" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
