Currently with In app purchase the only way to cancel an auto-renewing subscription is to do the following with the device:
Settings > Store > View my account > Manage my subscription
Is it possible programmatically to link directly to the Manage my subscription page in the app store? I know I can open the app store via something like
NSURL *url = [NSURL URLWithString:@"itms-apps://itunes.apple.com"];
[[UIApplication sharedApplication] openURL:url];
I have seen other apps do this but I can't seem to figure out how.
