Question

我收到了一个错误：

不兼容的块指针类型发送'void（^）（NSString * _ strong）'到'void（^）类型的参数（NSString * _strong，NSData * __ strong）'

当我在我的应用中实现MKStoreKit 4.3 on onComplete：

时

-(IBAction)purchaseFull {
    [[MKStoreManager sharedManager] buyFeature:@"productID"
                                onComplete:^(NSString* purchasedFeature)
    {
         NSLog(@"Purchased: %@", purchasedFeature);
         //purchaseBtn.hidden = YES;
    }
    onCancelled:^
    {
        NSLog(@"User Cancelled Transaction");
    }];
}

Answer 1

API you are trying to use有这样的方法：

// use this method to invoke a purchase
- (void) buyFeature: (NSString*) featureId         
         onComplete: (void (^)(NSString* purchasedFeature, 
                               NSData* purchasedReceipt)) completionBlock
        onCancelled: (void (^)(void)) cancelBlock;

但是，对于completionBlock参数，您正在传递

^(NSString* purchasedFeature) {
      NSLog(@"Purchased: %@", purchasedFeature);             
      //purchaseBtn.hidden = YES;        
}

表示您缺少第二个（NSData*）参数。

将您的代码更改为以下内容：

^(NSString* purchasedFeature, NSData* purchasedReceipt) {
      NSLog(@"Purchased: %@", purchasedFeature);             
      //purchaseBtn.hidden = YES;        
}

Answer 2

新API的答案：

 [[MKStoreManager sharedManager]
 buyFeature:kFeatureAId
 onComplete:^(NSString* purchasedFeature, NSData*purchasedReceipt, NSArray* availableDownloads)
 {
       NSLog(@"Purchased: %@", purchasedFeature);
 }
 onCancelled:^
 {
     NSLog(@"User Cancelled Transaction");
 }
 ];

编译MKStoreKit中的错误
