这是 json 发布请求的代码

sessionId =[[NSUserDefaults standardUserDefaults] objectForKey:@"session_id"];
        shouldReloadData=NO;
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getMerchantsListData:) name:@"getMerchantsListData" object:nil];
        NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                                latitude,@"latitude",
                                longitude,@"longitude",
                                //[NSString stringWithFormat:@"%d",categoryID],@"category_id",
                                [NSString stringWithFormat:@"%d",sortOrderID],@"sort_order",
                                @"5",@"page_size",
                                [NSString stringWithFormat:@"%@",searchMerchant.text],@"search_keyword",
                                [NSString stringWithFormat:@"%d",pageNumber],@"page_number",
                                sessionId,@"session_id",
                                nil];
        //searchKeyword=@"";
        NSLog(@"params %@",params);

        [[UFNetworking dataSourceInstance] getData:params toAPI:kGetMerchantList cache:NO secure:NO notification:@"getMerchantsListData"];

首先在字符串变量中获取所有值，然后像下面这样传递给字典..

   NSString *sort_order = [NSString stringWithFormat:@"%d",sortOrderID];
   NSString *search_keyword = [NSString stringWithFormat:@"%@",searchMerchant.text];
   NSString *page_number = [NSString stringWithFormat:@"%d",pageNumber];

   NSLog(@"\n\n Sort Order ==> %@, Search_keyWord ==> %@,Page_Number ==> %@",sort_order,search_keyword,page_number); /// check here what you get from the code..

   NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                                latitude,@"latitude",
                                longitude,@"longitude",
                                //[NSString stringWithFormat:@"%d",categoryID],@"category_id",
                                sort_order,@"sort_order",
                                @"5",@"page_size",
                                search_keyword,@"search_keyword",
                                page_number,@"page_number",
                                sessionId,@"session_id",
                                nil];

我希望这个答案对你有帮助..

我敢打赌你有一个无效的格式化程序。确保你没有%@在一个int或类似的东西上使用。

就我而言，我使用%的是印度尼西亚语，所以我必须添加%%本地化字符串，希望它可以帮助！
