在应用内购买后重新加载SKScene或View以删除iAd

在应用内购买之后，我已经成功从Sprite Kit游戏中删除了iAd，但是问题是该应用需要重新启动才能停止展示。

这使我相信，需要在应用内购买完成后以某种方式刷新或重新加载视图或场景（我已经尝试了很多方法），以便iAd消失。

应用内购买是在一个名为PurchasedViewController的单独类中进行的，我以模态形式进行了介绍。

目前，我正尝试在购买回购给根View Controller之后发送通知。

这是我的代码：

ViewController.m

#import "ViewController.h"
#import "Intro.h"
#import "PurchasedViewController.h"
#import <iAd/iAd.h>
#import "InAppManager.h"

@implementation ViewController

- (void)viewDidLoad {

  [super viewDidLoad];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(reload)
                                             name:@"reloadIntro"
                                           object:nil];

// Configure the view.
SKView * skView = (SKView *)self.view;


// Create and configure the scene.
SKScene *scene = [Intro sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;


 // Present the scene
 [skView presentScene:scene];
}

-(void)reload {
// Reload the View/Scene to remove iAds
 .....
}

- (void)viewDidAppear:(BOOL)animated {

   [super viewDidAppear:animated];

  //Display iAds
  if ( [[InAppManager sharedManager] isFeature1PurchasedAlready] == FALSE) {
    NSLog(@"iAds are showing");
    ADBannerView *adView = [[ADBannerView alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height - 480, 320, 50)];
    [self.view addSubview:adView];
  }

 //Remove iAds
 else if ( [[InAppManager sharedManager] isFeature1PurchasedAlready] == TRUE) {

    NSLog(@"iAds have been removed");
    ADBannerView *adView = [[ADBannerView alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height - 480, 320, 50)];
    adView.hidden = YES;
    [adView removeFromSuperview];
  }
}

PurchasedViewController.m

我不会在这里放很多In App Purchase代码，因为我知道它可以工作，并且我也已经成功删除了Chartboost的广告。

-(void) unlockProduct1 {

  if ( [[InAppManager sharedManager] isFeature1PurchasedAlready] == NO) {
     NSLog(@"Product 1 was not bought yet");
    [buyProduct1Button setBackgroundImage:[UIImage imageNamed:@"Remove_Ads"] forState:UIControlStateNormal];
 }

  else {
    NSLog(@"Product 1 WAS bought");
    [buyProduct1Button setBackgroundImage:[UIImage imageNamed:@"Purchased"] forState:UIControlStateNormal];

    // Sending Notification to ViewController.m
    NSLog(@"Did Send notification reloadIntro");
    [[NSNotificationCenter defaultCenter] postNotificationName:@"reloadIntro" object:nil];
  }
}

- (IBAction)dismissPurchasedVC:(UIButton *)sender {
    [self dismissModalViewControllerAnimated:YES];
 }
