如何在CloudKit中存储大图像？

问题描述

我尝试将图片上传到 CloudKit ，并将其存储为 NSData ，但图片相对较大，用相机拍摄，我收到此错误：

I tried to upload a picture to CloudKit, and store it as NSData, but with a relatively bigger picture, taken with camera, I get this error:

Error saving record <CKRecordID: 0x15998770; 04359DFA-8370-4000-9F53-5694FC53FA9C:(_defaultZone:__defaultOwner__)> to server: record too large id=04359DFA-8370-4000-9F53-5694FC53FA9C of type UserSetting

什么数据的最大大小是否可以存储在 CloudKit ？

我尝试了两张图片，并绘制了它们的大小。

I tried with two image, and I plotting out size of them.

let d = UIImagePNGRepresentation(image)
println("d.length: \(d.length)")

• d.length：55482 < - 作品


• d.length：17614327 < - 不起作用


• d.length: 55482 <- works
• d.length: 17614327 <- does not work

推荐答案

您应该将图片存储为CKAsset。对于CKRecord，存在尺寸限制。对于CKAsset，没有（除了CloudKit存储限制）。根据文档：

You should store pictures as a CKAsset. For a CKRecord there is a size limitation. For a CKAsset there is not (beside the CloudKit storage limitations). According to the documentation:

你可以像这样创建一个CKAsset：

You can create a CKAsset like this:

var File : CKAsset = CKAsset(fileURL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("image-not-available", ofType: "jpg")!))
