Question

我正在使用AFNetworking 2.0向我的返回JSON数据的Web服务发出POST请求。

{
    post =         {
        "first_name" = Joe;
        "last_name" = Blogs;
        "user_id" = 1;
    };
},
    {
    post =         {
        "first_name" = Bill;
        "last_name" = Gates;
        "user_id" = 2;
    };
}

我能够将responseObject打印到控制台上，显示我的JSON数据。

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"user": @"root"};
[manager POST:@"http://192.168.0.100/webservice.php" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject)
{
    NSString *responseString = [operation responseString];

    NSError *error;
    NSArray *json = [NSJSONSerialization
                     JSONObjectWithData:[responseString dataUsingEncoding:NSUTF8StringEncoding]
                     options:kNilOptions
                     error:&error];

    for (NSDictionary *dictionary in json)
    {
        NSString *firstName = [[dictionary objectForKey:@"post"] valueForKey:@"first_name"];
        NSLog(@"%@", firstName);
        NSString *lastName = [[dictionary objectForKey:@"post"] valueForKey:@"last_name"];
        NSLog(@"%@", lastName);
    }

} failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
    NSLog(@"Error: %@", error);
}];

每个“post”将用于我的View Controller上的表格单元格。我正在努力了解如何使每个帖子成为数组中的对象。任何有用的帮助。

您可以使用此代码剪切来执行所需的功能：

        NSString *responseString = [operation responseString];
        NSData *data= [responseString dataUsingEncoding:NSUTF8StringEncoding];
        NSError *error;
        NSArray* results = [NSJSONSerialization JSONObjectWithData:data
                                                       options:0
                                                         error:&error];
             for (int i=0; i<results.count; i++)
             {
                 NSDictionary *res=[results objectAtIndex:i];
                 NSDictionary *res2=[res objectForKey:@"post"];
                 [self.storesArray addObject:res2];

             }
             [self.tableView reloadData];

并在您的CellForRowAtIndexPath方法中，使用此代码剪切显示您单元格中的数据：

NSDictionary *res=[self.storesArray objectAtIndex:indexPath.row];
cell.firstName.text=[res objectForKey:@"first_name"];
cell.lastName.text=[res objectForKey:@"last_name"];

此NSDictionary适用于键值对样式，因此您只需提及键名即可获取任意键的值，并获取该键的值。
