Question

愚蠢的问题。我只是粘贴示例AFNetworking代码：

NSURL *url = [NSURL URLWithString:@"https://gowalla.com/users/mattt.json"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];

AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
    NSLog(@"Name: %@ %@", [JSON valueForKeyPath:@"first_name"], [JSON valueForKeyPath:@"last_name"]);
} failure:nil];

[operation start];

但是，没有任何反应。如果我输出操作到NSLog，它看起来像是取消了请求：

<AFJSONRequestOperation: 0x81655f0, state: isExecuting, cancelled: NO request: <NSURLRequest https://gowalla.com/users/mattt.json>, response: (null)>

我做错了什么？

最好的办法是添加一个失败块，然后检查

中提供的变量

NSURL *url = [NSURL URLWithString:@"https://gowalla.com/users/mattt.json"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];

AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
    NSLog(@"Name: %@ %@", [JSON valueForKeyPath:@"first_name"], [JSON valueForKeyPath:@"last_name"]);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
    NSLog(@"%@", [error localizedDescription]);
}];

[operation start];

AFNetworking：取消，无请求
