我尝试了几种方法来使用 UIAlertController，而不是 UIAlertView。我尝试了几种方法，但无法使警报操作起作用。 这是我的代码，在 IOS 8 和 IOS 9 中运行良好，但出现了不推荐使用的标志。我尝试了下面的优雅建议，但我无法使其在这种情况下发挥作用。我需要提交我的应用程序，这是最后要解决的问题。感谢您提供任何进一步的建议。我是新手。

#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
                                                    delegate:self
                                           cancelButtonTitle:@"Yes, please"
                                           otherButtonTitles:@"No, thanks", nil];
       [alert show];

        NSString *path = [[NSBundle mainBundle] pathForResource:@"cow" ofType:@"wav"];
        _pop =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
        [_pop play];
        [self dismissViewControllerAnimated:true completion:nil];

    } else {
        if (gamePlaysCount == 1)  {
            // Create & store the next 5 mins when player gets 3 more lives
            nextDateToPlay = [[NSDate date] dateByAddingTimeInterval:60*60*0.1];
            NSLog(@"CURRENT DATE: %@", [NSDate date]);
            NSLog(@"NEXT DAY: %@", nextDateToPlay);
            [[NSUserDefaults standardUserDefaults]setObject: nextDateToPlay    forKey:@"nextDateToPlay"];
            NSLog(@"nextDateToPlay: %@", nextDateToPlay);

            UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"

                                                          delegate:self
                                                 cancelButtonTitle:@"Got it!"
                                                 otherButtonTitles:@"Start", nil];
            [alert show];
        } else {

            if (gamePlaysCount == 3)  {
                UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"
                                                               message: THREE_PLAYS_LIMIT_MESSAGE3
                                                              delegate:self
                                                     cancelButtonTitle:@"Yep, I Know!"
                                                     otherButtonTitles:@"Start", nil];
                [alert show];
            }
        }
    }
}

}

// IAP NOT MADE =============================

#pragma mark - ALERTVIEW DELEGATE ============================

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {

if ([[alertView buttonTitleAtIndex:buttonIndex] isEqualToString:@"Yes, please"]) {

    UIStoryboard *storyboard = self.storyboard;
    MenuViewController *svc = [storyboard instantiateViewControllerWithIdentifier:@"Store"];
    svc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
    [self presentViewController:svc animated:YES completion:nil];

        }

}

最佳答案

从 iOS8 Apple 提供新的 UIAlertController 类，您可以使用它来代替现在已弃用的 UIAlertView，它也在弃用消息中说明:

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

所以你应该使用这样的东西

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];

关于ios - UIAlertView 首先弃用 IOS 9，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32690086/
