这是json的POST请求

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]; 
     //[email protected]""; 
     NSLog(@"params %@",params); 

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

可以编辑您的问题以添加代码组成方法“['merchantListViewController getMerchantsData]'”？ –

请张贴一些代码，您的应用程序崩溃.. –

请张贴一些代码来识别您的崩溃...使用异常breakPoint来查找应用程序崩溃 – Rajneesh071

第一借此在字符串变量的所有值，然后传递给字典像波纹管..

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..

谢谢帕拉斯吉 –

欢迎@NagarajaYadav如果它对你有用然后接受答案和upvote请队友 –

嗨它没有解决问题，但使我的调试很容易 –

我敢打赌，你有一个无效的格式的代码。确保你没有在int或类似的东西上使用%@。
