ios - 从 CoreData 获取返回 AnyObject

我正在从 coreData 获取实体数据，它返回 AnyObject，我尝试了很多在 NSDictionary 和 NSArray 中进行转换，但它无法转换任何类型。`

    var dictData:NSDictionary?
    let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
    let context = appDelegate.managedObjectContext;
    // self.selectedArray = response.objectForKey("retailers") as! NSArray;
    let fetchRequest2 = NSFetchRequest()
    let entityDescription2 = NSEntityDescription.entityForName("Offers", inManagedObjectContext: context)
    fetchRequest2.entity  = entityDescription2

    //fetchRequest2.returnsObjectsAsFaults = false

    do {
        let result2 : NSDictionary = try context.executeFetchRequest(fetchRequest2) as! NSDictionary
                   print("Result:",result2)
        for result in (result2 as? NSDictionary)!{

            if let data : NSDictionary = result as? NSDictionary{

                print(data)
            }

报价实体包含 No Of 字段。请帮助。它会受到赞赏。

                print("result: ",result)
                print("dictData:",dictData)

` }

最佳答案

context.executeFetchRequest() 返回 [AnyObject] ，而不是 AnyObject 。

你需要做:

if let results = context.executeFetchRequest(fetchRequest2) as? [MyObjectType] {
      for object in results {
        //do thing
    }
  }
