问题描述

我从我的服务器获取标识符列表，然后在产品请求中将它们传递给Apple。这是我的代码，下面是我得到的错误。
发生这种情况时，iPhone 4不会崩溃。

I'm fetching a list of identifiers from my server, then passing them off in a products request to Apple. Here's my code, and below is the error I'm getting. The iPhone 4 is not crashing when this happens.

-(void)didReceiveData:(NSArray *)data {
NSLog(@"Received Identifiers: %@",data);
NSSet *productIdentifiers = [NSSet setWithArray:data];
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers]; 
productsRequest.delegate = self;
[productsRequest start];
NSLog(@"productsRequest should have started by now");
}

推荐答案

从日志输出中，我猜数据是一个数组数组。

From your log output, I guess data is an array of arrays.

您应该只将一个NSString（您的产品ID）数组传递给 setWithArray：

You should pass only an array of NSString (your product ids) to setWithArray:
