使用RestKit，使用block加载对象，何时以及如何取消请求? [英] Using RestKit, use block to load object, when and how to cancel the request?

问题描述

[[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"app/site_pattern" usingBlock:^(RKObjectLoader* loader) {
    [loader setObjectMapping:clientMappring];
    loader.delegate = self;
    shopLoader = loader;
}];

上面，我使用块函数在应用程序中加载一些数据，但是当我弹出该ViewController时，我不知道何时以及如何取消此请求.

Above, I use the block function to load some data in my app, but when I pop this viewcontroller, I don't know when and how to cancel this request .

有什么主意吗?

- (void)showSelectShop
{

    SelectShopViewController * selectShopViewController = [[SelectShopViewController alloc] initWithNibName:@"SelectShopViewController" bundle:nil];
    [self.navigationController pushViewController:selectShopViewController animated:YES];
}

更多:

我尝试在viewDidUnload中取消它

I try to cancel it in the viewDidUnload

- (void)viewDidUnload
{
    [super viewDidUnload];
    [shopLoader cancel];
}

但是没有用.我仍然遇到错误.

But it didn't work. I still getting error.

推荐答案

我通过添加

- (void)viewWillDisappear:(BOOL)animated
{
    [shopLoader cancel];
    shopLoader.delegate = nil;
    shopLoader = nil;
}

我仍然想知道是否不想在viewWillDisappear中取消此请求，这些行应写入哪个函数?

I still want to know if I don't want to cancel this request in viewWillDisappear, which function do those lines should be written in?
