I have a free version of app. And there is a link to a full version in free app. The link works fine in iOS 6. But in iOS 7 it shows a blank page. Any help is appreciated!
Pretty strange link you are using. I use:
http://itunes.apple.com/app/id?mt=8
and everything works...
In apps supporting iOS6 and above, I suggest furthermore the use of StoreKit, so you can display your app page in the App Store without leaving your app. You can do that like this:
- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController
{
[viewController dismissViewControllerAnimated:YES completion:nil];
}
- (void)showAppWithIdentifier:(NSNumber *)identifier
{
if ([SKStoreProductViewController class]) {
SKStoreProductViewController *controller = [[SKStoreProductViewController alloc] init];
controller.delegate = self;
[controller loadProductWithParameters:@{ SKStoreProductParameterITunesItemIdentifier : identifier }
completionBlock:NULL];
[self presentViewController:controller animated:YES completion:nil];
return;
}
// Fall back to opening App Store for iOS 5.
... open the link as you are already doing
}
