AFNetworking 2：如何取消AFHTTPRequestOperationManager请求？ [英] AFNetworking 2: How to cancel a AFHTTPRequestOperationManager request?

问题描述

我将网络功能从 AFNetworking 迁移到了 AFNetworking v2 ，而不是将 AFHttpClient 我也在使用 AFHTTPRequestOperationManager 来支持iOS6。

I migrated my networking functionality from AFNetworking to AFNetworking v2 and instead of AFHttpClient I am using AFHTTPRequestOperationManager to support iOS6 as well.

我的问题是 AFHttpClient 具有使用

- (void)cancelAllHTTPOperationsWithMethod:(NSString *)method path:(NSString *)path;

方法，在 AFHTTPRequestOperationManager 中没有这种明显的方法。

method, in the AFHTTPRequestOperationManager there is no such obvious method.

我到目前为止所做的是将 AFHTTPRequestOperationManager 子类化并声明一个iVar

What I've done up to now is subclassing AFHTTPRequestOperationManager and declaring an iVar

AFHTTPRequestOperation *_currentRequest;

当我发出请求时，代码类似于

When I make a request the code is something like

- (void)GetSomething:(NSInteger)ID success:(void (^)(MyResponse *))success failure:(void (^)(NSError *))failure
{
    _currentRequest = [self GET:@"api/something" parameters:@{@"ID": [NSNumber numberWithInteger:ID]} success:^(AFHTTPRequestOperation *operation, id responseObject) {
        MyResponse *response = [MyResponse responseFromDictionary:responseObject];
        success(response);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        failure(error);

    }];
}

我有一个

- (void)cancelCurrentRequest;

所能做的所有方法

- (void)cancelCurrentRequest
{
    if(_currentRequest) {
        [_currentRequest cancel]; _currentRequest = nil;
    }
}

现在，我认为这不是好习惯并在调用该方法时得到（NSURLErrorDomain错误-999。），这就是为什么我需要一些正确完成此操作的建议的原因。

Now, I don't think this is good practice and when the method is called I get (NSURLErrorDomain error -999.) which is why I need some advice on getting this done correctly.

谢谢。

推荐答案

[manager.operationQueue cancelAllOperations];
