앱 구매시로드 중 활동 표시기를 표시하는 방법은 무엇입니까?

Question

인앱 구매 기능을 호출하는 버튼이 있습니다. 제품을로드하는 동안로드 휠을 표시하고 UIAlertView가 구매 확인을 표시하면이를 닫습니다. MBAlertView를 사용하여 내 응용 프로그램에서 다른 메시지를 표시하고 있으며 여기에서도이 메시지를 사용합니다. 어떻게해야합니까? 사용자가 버튼을 누를 때 표시하고 응답을 받으면 해제합니다.

여기 내 코드가 있습니다.

- (IBAction)buyCoffeeInAppPurchase:(id)sender { 
    SKProductsRequest *request= [[SKProductsRequest alloc] 
           initWithProductIdentifiers: [NSSet setWithObject:  @"com.giovannibalestra.emergencycall.Thankyoudeveloper"]]; 
    request.delegate = self; 
    [request start]; 
    // I should add something like this line of code to show the activity indicator but I can only set hidesAfter some seconds 
    // [MBHUDView hudWithBody:@"Wait." type:MBAlertViewHUDTypeActivityIndicator hidesAfter:4.0 show:YES]; 
} 
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { 
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self]; 

    NSArray *myProduct = response.products; 
    NSLog(@"%@",[[myProduct objectAtIndex:0] productIdentifier]); 

    SKPayment *newPayment = [SKPayment paymentWithProduct:[myProduct objectAtIndex:0]]; 
    [[SKPaymentQueue defaultQueue] addPayment:newPayment]; 

} 

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions { 
    for (SKPaymentTransaction *transaction in transactions) 
    { 
     switch (transaction.transactionState) 
     { 
      case SKPaymentTransactionStatePurchased: 
       [self completeTransaction:transaction]; 
       break; 
      case SKPaymentTransactionStateFailed: 
       [self failedTransaction:transaction]; 
       break; 
      case SKPaymentTransactionStateRestored: 
       [self restoreTransaction:transaction]; 
      default: 
       break; 
     } 
    } 
} 

- (void)completeTransaction:(SKPaymentTransaction *)transaction { 
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
} 

- (void)restoreTransaction:(SKPaymentTransaction *)transaction { 
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
} 

- (void)failedTransaction:(SKPaymentTransaction *)transaction { 
    if (transaction.error.code != SKErrorPaymentCancelled) 
    { 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Purchase Unsuccessful" 
                 message:@"Your purchase failed. Please try again." 
                 delegate:self 
               cancelButtonTitle:@"OK" 
               otherButtonTitles:nil]; 
     [alert show]; 
    } 
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
}

쇼로드의 경우 MBProgressHUD를 사용할 수도 있습니다. 로딩 과정을 보여주는 쉬운 방법. MBProgressHUD.h & .m 파일 (인터넷 &)을 xcode 프로젝트에 복사하십시오.

HOW TO USE: 가져 오기 당신도 .H &하는 .m 파일 &이 MBProgressHUD * HUD에서이 # import를 "MBProgressHUD.h"; .h 파일에서. * (SKPaymentTransaction : completeTransaction (무효) -

- (IBAction)buyCoffeeInAppPurchase:(id)sender { 

    HUD = [[MBProgressHUD alloc] initWithFrame:CGRectMake(0, 0, 320, 460) ]; 
     HUD.labelText = @"Fetching..."; 
     [self.view addSubview:HUD]; 
     [HUD show:YES]; 


    SKProductsRequest *request= [[SKProductsRequest alloc] 
           initWithProductIdentifiers: [NSSet setWithObject:  @"com.giovannibalestra.emergencycall.Thankyoudeveloper"]]; 
    request.delegate = self; 
    [request start]; 
    // I should add something like this line of code to show the activity indicator but I can only set hidesAfter some seconds 
    // [MBHUDView hudWithBody:@"Wait." type:MBAlertViewHUDTypeActivityIndicator hidesAfter:4.0 show:YES]; 
} 
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { 
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self]; 

    NSArray *myProduct = response.products; 
    NSLog(@"%@",[[myProduct objectAtIndex:0] productIdentifier]); 

    SKPayment *newPayment = [SKPayment paymentWithProduct:[myProduct objectAtIndex:0]]; 
    [[SKPaymentQueue defaultQueue] addPayment:newPayment]; 

    [HUD hide:YES]; 
    [HUD removeFromSuperViewOnHide]; 

} 

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions { 
    for (SKPaymentTransaction *transaction in transactions) 
    { 
     switch (transaction.transactionState) 
     { 
      case SKPaymentTransactionStatePurchased: 
       [self completeTransaction:transaction]; 
       break; 
      case SKPaymentTransactionStateFailed: 
       [self failedTransaction:transaction]; 
       break; 
      case SKPaymentTransactionStateRestored: 
       [self restoreTransaction:transaction]; 
      default: 
       break; 
     } 
    } 
} 

- (void)completeTransaction:(SKPaymentTransaction *)transaction { 
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
} 

- (void)restoreTransaction:(SKPaymentTransaction *)transaction { 
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
} 

- (void)failedTransaction:(SKPaymentTransaction *)transaction { 
    if (transaction.error.code != SKErrorPaymentCancelled) 
    { 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Purchase Unsuccessful" 
                 message:@"Your purchase failed. Please try again." 
                 delegate:self 
               cancelButtonTitle:@"OK" 
               otherButtonTitles:nil]; 
     [alert show]; 
    } 
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
}

- (void)paymentQueue:(SKPaymentQueue *)queue 
updatedTransactions:(NSArray *)transactions 
{ 
    for (SKPaymentTransaction *transaction in transactions) 
    { 
     if (transaction.transactionState == SKPaymentTransactionStatePurchased) { 
      [self completeTransaction:transaction]; 
     } 
     if (transaction.transactionState == SKPaymentTransactionStateFailed) { 
      [self failedTransaction:transaction]; 
     } 
     if (transaction.transactionState == SKPaymentTransactionStateRestored) { 
      [self restoreTransaction:transaction]; 
     } 
     else { 
      // Do something. 
     } 

     // You can dismiss your Activity Indicator (MBHUDView) here. 
    } 
}

안녕하세요 간단하게 활동 표시를 적용 할 때 구매 버튼을 사용자가 클릭이 방법 후 활동 표시를 중지 같은 그런하는 .m에서 코드 파일이 보인다)트랜잭션. 실패한 거래에서 멈추는 것을 잊지 마세요, 다른 현명한 활동 표시기가 움직이기 시작합니다. 활동 표시기가 스레드를 통해 호출해야하는 경우가 있습니다. 그러니 한번 시도해보십시오.
