HTTP後W/JSON從iOS的

軌服務器

我已經通過設置內容類型爲application/JSON和此JSON代碼成功地使用HTTP客戶端做一個帖子：HTTP後W/JSON從iOS的

{ 
    "order": { 
     "name": "Tia Carter", 
     "location": "Corams", 
     "phone_number": "707", 
     "food": "Bobcat Burger" 
    } 
}

代碼工作完美該訂單已在數據庫中註冊。我正在嘗試將其應用到我的iOS應用程序中，但不斷收到關於json中冒號的語法錯誤。這是客觀C代碼：

NSURL *nsURL = [[NSURL alloc] initWithString:@"http://0.0.0.0:3000/orders.json"]; 
NSMutableURLRequest *nsMutableURLRequest = [[NSMutableURLRequest alloc] initWithURL:nsURL]; 

// Set the request's content type to application/x-www-form-urlencoded 
[nsMutableURLRequest setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 

// Set HTTP method to POST 
[nsMutableURLRequest setHTTPMethod:@"POST"]; 

// Set up the parameters to send. 
NSString *paramDataString = [NSString stringWithFormat:@ 
          "{ "order": {"%@:" ="%@","%@:"="%@","%@:"="%@","%@:"="%@"}}", @"name", _name.text, @"location", _location.text, @"phone_number", _phoneNumber.text, @"food", _order.text]; 

// Encode the parameters to default for NSMutableURLRequest. 
NSData *paramData = [paramDataString dataUsingEncoding:NSUTF8StringEncoding]; 

// Set the NSMutableURLRequest body data. 
[nsMutableURLRequest setHTTPBody: paramData]; 

// Create NSURLConnection and start the request. 
NSURLConnection *nsUrlConnection=[[NSURLConnection alloc]initWithRequest:nsMutableURLRequest delegate:self];

我會很感激任何想法或指導。謝謝。
