这是json回应：

"FirstName": "Anvar","LastName": "Azizov","Website": null,"About": null,@H_403_6@ 
 
我将非常感谢帮助处理它.
 
 
UPD1：在这一刻,我决定以另一种方式做：
 
  
 
if let jsonResult = responSEObject as? [String: AnyObject] {                    
    var jsonCleanDictionary = [String: AnyObject]()

    for (key,value) in enumerate(jsonResult) {
      if !(value.1 is NSNull) {
         jsonCleanDictionary[value.0] = value.1
      }
    }
}@H_403_6@
