在我的应用程序中，有一段代码，如果按下按钮，用户可以升级应用程序并删除广告，它会调用 MKStoreKit，一旦用户购买升级，广告会保留在应用程序中，直到应用程序重新启动。
我想解决这个问题，所以广告会立即删除，但我该怎么做呢？
这是一些代码；
-(IBAction)removeAds:(id)sender
{
if (![MKStoreManager isFeaturePurchased:@"com.davidsapps.puzzler.removeads"]) { //
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Upgrade App" message:@"To upgrade and remove all advertisements from this app Please click OK to purchase the upgrade!" delegate:self cancelButtonTitle:@"No Thanks" otherButtonTitles:@"Yes Please",nil];
[alert show];
[alert release];
}
}
它链接到的警报；
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0){
//cancel button clicked. Do something here or nothing here
}
else{
//other button indexes clicked
[[MKStoreManager sharedManager] buyFeature:@- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0){
//cancel button clicked. Do something here or nothing here
}
else{
//other button indexes clicked
[[MKStoreManager sharedManager] buyFeature:@"com.idevver.mybatterypal.upgrade"];
}
}
}
使用 MKStoreKit
我可以做些什么来让它删除广告而无需用户重新启动应用程序？
谢谢，
克里斯
编辑 - 广告是 Admob 中介，在 ViewDidLoad 中使用此代码
- (void)viewDidLoad {
bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait];
bannerView_.adUnitID = MY_BANNER_UNIT_ID;
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;
CGFloat screenHeight = screenRect.size.height;
CGFloat screenXPos = (screenWidth /2);
CGFloat screenYPos = screenHeight - 90;
[bannerView_ setCenter:CGPointMake(screenXPos, screenYPos)];
bannerView_.rootViewController = self;
bannerView_.adUnitID = MY_BANNER_UNIT_ID;
bannerView_.rootViewController = self;
[self.view addSubview:bannerView_];
这是实际调用广告横幅的代码，它位于 viewDidLoad 后面的 if/else 语句中
if (![MKStoreManager isFeaturePurchased:@"com.davidsapps.puzzler.removeads"]) { //
[bannerView_ loadRequest:[GADRequest request]];
}
所以我想在购买该功能时不知何故，我需要在 MKStoreManager.m 文件中添加一些内容来消除上面的bannerView_代码？
那行得通吗？
