UIAlertView primer IOS 9 obsoleto

He probado varias formas de usar UIAlertController, en lugar de UIAlertView. Intenté de varias formas pero no puedo hacer que la acción de alerta funcione. Aquí está mi código que funciona bien en IOS 8 e IOS 9, pero aparece con indicadores obsoletos. Probé la elegante sugerencia a continuación, pero no puedo hacer que funcione en este contexto. Necesito enviar mi aplicación y esto es lo último que debo abordar. Gracias por cualquier otra sugerencia. Soy un novato

Desde iOS8, Apple proporciona una nueva UIAlertControllerclase que puede usar en lugar de UIAlertView, que ahora está en desuso, también se indica en el mensaje de obsolescencia:

UIAlertView está en desuso. Utilice UIAlertController con un estilo preferido de UIAlertControllerStyleAlert en su lugar

Entonces deberías usar algo como esto

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];

//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];
}

Si desea usar esta alerta en la clase NSObject, debe usar como:

-(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:^{
    }];
});
}

La versión rápida de la nueva implementación es:

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

Xcode 8 + Swift

Suponiendo que selfes un 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
    }
}

Haga que la categoría UIAlertController + AlertController sea:

UIAlertController + AlertController.h

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

@interface UIAlertController (AlertController)

+ (instancetype)showAlertIn:(UIViewController *)controller
                  WithTitle:(NSString *)title
                    message:(NSString *)message
          cancelButtonTitle:(NSString *)cancelButtonTitle
          otherButtonTitles:(NSString *)otherButtonTitle
                   tapBlock:(UIAlertCompletionBlock)tapBlock;
@end

UIAlertController + AlertController.m

@implementation UIAlertController (NTAlertController)

+ (instancetype)showAlertIn:(UIViewController *)controller
                  WithTitle:(NSString *)title
                    message:(NSString *)message
          cancelButtonTitle:(NSString *)cancelButtonTitle
          otherButtonTitles:(NSString *)otherButtonTitle
                   tapBlock:(UIAlertCompletionBlock)tapBlock {

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

    if(cancelButtonTitle != nil) {

        UIAlertAction *cancelButton = [UIAlertAction
                                       actionWithTitle:cancelButtonTitle
                                       style:UIAlertActionStyleCancel
                                       handler:^(UIAlertAction *action)
                                       {
                                           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

en su 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];

 }];

NOTA: Si desea agregar más de dos botones, agregue otro UIAlertAction más al UIAlertController.

Utilice UIAlertController en lugar de 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];
}

Probé los métodos anteriores y nadie puede mostrar la vista de alerta, solo cuando pongo el presentViewController:método en una dispatch_asyncoración:

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

Consulte ¿ Alternativa a UIAlertView para iOS 9? .

 UIAlertController * alert = [UIAlertController
                                 alertControllerWithTitle:@"Are you sure you want to logout?"
                                 message:@""
                                 preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction* yesButton = [UIAlertAction

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

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