iOS崩溃报告SKProductsRequest

Question

有人可以确认我的想法是由于SKProductsRequestDelegate仍然被分配而生成以下崩溃报告,但代码本身不是吗？即VC已关闭？

StoreKit: __34-[SKProductsRequest _handleReply:]_block_invoke + 442

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
Exception Subtype: KERN_INVALID_ADDRESS at 0x41682340

如果我的想法是正确的,我可以通过以下方式解决:

request.delegate = nil;
[request cancel];
request = nil;

如果我不正确,有人可以为我提供更多的信息吗？

谢谢.

对于ref,我添加以下代码确实纠正了这个问题.

request.delegate = nil;
[request cancel];
request = nil;
