iphone - 恢复应用内购买时没有出现 'buy' 提示？是否可以？

Question

我目前有应用内购买“恢复”按钮，

它确实工作，但本质上它要求用户在整个过程中“购买”升级(就像普通的应用程序内一样)我担心这会

a) 被苹果拒绝b) 吓唬用户，让他们认为他们再次付费

有什么办法可以改变它，让它有不同的消息吗？

-(IBAction)restore:(id)sender
{=
    [[SKPaymentQueue defaultQueue]
     addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue]
     restoreCompletedTransactions];

    UIAlertView *alert;

    alert = [[[UIAlertView alloc] initWithTitle:@"Restoring Your Purchases, Please Wait..." message:nil delegate:self cancelButtonTitle:nil otherButtonTitles: nil] autorelease];
    [alert show];

    UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

    // Adjust the indicator so it is up a few pixels from the bottom of the alert
    indicator.center = CGPointMake(alert.bounds.size.width / 2, alert.bounds.size.height - 50);
    [indicator startAnimating];
    [alert addSubview:indicator];
    [indicator release];

    [alert dismissWithClickedButtonIndex:0 animated:YES];

    [[MKStoreManager sharedManager] buyFeature];=
}

-(void)productPurchased
{
    for (UIView *view in self.view.subviews)
    {
        if (view.tag==2000)
        {
            [view removeFromSuperview];
        }
    } 

    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Thank you" message:@"Your restore was successful." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
    [alert show];
    [alert release];
}

// error restore
- (void)failed
{
    for (UIView *view in self.view.subviews)
    {
        if (view.tag==2000)
        {
            [view removeFromSuperview];
        }
    }

    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Error" message:@"Your restore has failed." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
    [alert show];
    [alert release];
}

Answer 1

完全可以，事实上这是必要的。看我的answer有点类似question .

本质上，当您按下恢复按钮时，应该要求用户验证他们的帐户；这是由 StoreKit 处理的。如果找到该帐户的 IA 购买行为，则该过程应该开始以与第一次购买该商品相同的方式恢复购买行为，只是没有提示实际购买。
