UIAlertView najpierw przestarzałe IOS 9

Wypróbowałem kilka sposobów użycia UIAlertController zamiast UIAlertView. Wypróbowałem kilka sposobów, ale nie mogę sprawić, by działanie alarmowe zadziałało. Oto mój kod, który działa dobrze w IOS 8 i IOS 9, ale wyświetla się z przestarzałymi flagami. Wypróbowałem elegancką sugestię poniżej, ale nie mogę sprawić, by działała w tym kontekście. Muszę przesłać moją aplikację, a to ostatnia rzecz, którą należy się zająć. Dziękuję za dalsze sugestie. Jestem nowicjuszem.

#pragma mark - BUTTONS ================================

    [[NSUserDefaults standardUserDefaults]setInteger:gamePlaysCount forKey:@"gamePlaysCount"];

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

Od iOS8 Apple dostarcza nową UIAlertControllerklasę, której można używać zamiast UIAlertView, który jest obecnie przestarzały, jest to również określone w komunikacie o wycofaniu:

UIAlertView jest przestarzały. Zamiast tego użyj UIAlertController z preferowanym stylem UIAlertControllerStyleAlert

Więc powinieneś użyć czegoś takiego

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];
}

Jeśli chcesz użyć tego alertu w klasie NSObject, powinieneś użyć:

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

Szybka wersja nowej implementacji to:

 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

Zakładając, że selfjest 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
    }
}

Ustaw kategorię UIAlertController + AlertController jako:

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

w Twoim 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];

 }];

UWAGA: Jeśli chcesz dodać więcej niż dwa przyciski, dodaj jeszcze jedną UIAlertAction do UIAlertController.

Użyj UIAlertController zamiast 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];
}

Wypróbowałem powyższe metody i nikt nie może pokazać widoku alertu, tylko wtedy, gdy umieszczę presentViewController:metodę w dispatch_asynczdaniu:

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

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

    UIAlertAction* yesButton = [UIAlertAction
                                actionWithTitle:@"Logout"
                                style:UIAlertActionStyleDestructive
                                handler:^(UIAlertAction * action)
                                {

                                }];

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

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

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

Sprawdź to:

UIAlertController *alertctrl =[UIAlertController alertControllerWithTitle:@"choose Image" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
    UIAlertAction *camera =[UIAlertAction actionWithTitle:@"camera" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [self Action];  //call Action need to perform 
    }];

[alertctrl addAction:camera];
-(void)Action

                                                                   message:"Message"
                                                            preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
