我的代码如下：

NSString *urlString = [[NSString stringWithFormat:@"/players?skip=%ld",(long)skipSize] DVURL];
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
//[request set]
[request setValuesForKeysWithDictionary:[filter filteringDictionary]];
AFHTTPRequestOperation *operation =
[[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:
 ^(AFHTTPRequestOperation *operation, id responseObject) {
     NSLog(@"responseObject %@", responseObject);

     totalPages = ([[responseObject
                     objectForKey:@"count"] intValue] / 20);
     NSLog(@"%@",[responseObject objectForKey:@"players"]);
     for (NSDictionary *playerDict in [responseObject objectForKey:@"players"]) {
         DVPlayer *player = [[DVPlayer alloc] initWithDictionary:playerDict];
         if (![self.playerArray.players containsObject:player]) {
             [self.playerArray.players addObject:player];
         }
     }
     [playerCollectionView reloadData];

 } failure:
 ^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"Error: %@", [error localizedDescription]);
     [[[UIAlertView alloc]
        initWithTitle:@"Error fetching players!"
        message:@"Please try again later"
        delegate:nil
        cancelButtonTitle:@"OK"
        otherButtonTitles:nil] show];
 }];

[operation start];

当我使用 时AFHTTPRequestOperationManager，我用作NSDictionaryGET 方法的参数。

所以我想[request setValuesForKeysWithDictionary:[filter filteringDictionary]];会是对应的。

但我得到一个错误：

setValue:forUndefinedKey:]：此类不符合键值编码的名称（例如）

我构建参数是NSDictionary为了方便......我不能将参数设置为NSDictionary使用时AFHTTPRequestOperation，不是AFHTTPRequestOperationManager吗？

请帮帮我

AFHTTPRequestOperation将 aNSURLRequest作为初始化参数。因此，您需要自己处理序列化，将其附加到您的 url，然后对 url 进行编码：

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:[yourUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]];

还有一个更容易的原因AFHTTPRequestOperationManager；）
