这是json post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"]; 

Answer 1

首先把这个全部的值放在stringvariables中，然后像波纹pipe一样传递给字典。

  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int上使用%@或类似的东西。
