“ NSInvalidArgumentException”，原因：“-[_ UIBackgroundTaskInfo setStoreObserver：]：无法识别的选择器已发送到实例0x282b20780”

Question

在更新一些较旧的代码的过程中，并且在代码启动时，它在启动时立即崩溃。我使用的是XCode 10，以前在XCode 7/8中可以正常使用

AppController.mm中的这一行

[[MKStoreManager sharedManager] requestProductData];

那条线将您带到

MKStoreManager.m

- (void) requestProductData
{
    SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers: 
                                 [NSSet setWithObjects: /*featureAllLevels, */ foodIAP, vanityIAP, dressIAP, iceIAP, allIAP, nil]]; // add any other product here
    request.delegate = self;
    [request start];
}

错误本身是

objc[680]: MKStoreManager object 0x281ecd020 overreleased while already deallocating; break on objc_overrelease_during_dealloc_error to debug 2019-09-19 12:15:18.342037+0100 PoolParty[680:66967] -[_UIBackgroundTaskInfo setStoreObserver:]: unrecognized selector sent to instance 0x281ecd020 2019-09-19 12:15:18.342502+0100 PoolParty[680:66967] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[_UIBackgroundTaskInfo setStoreObserver:]: unrecognized selector sent to instance 0x281ecd020'

如果有人能帮助我，我会努力解决这一问题！
