如何使用swift上传和加载来自云套件的图像？

我使用什么属性类型？

我用什么代码？这是我目前使用的代码......

func SaveImageInCloud(ImageToSave: UIImage) {
        let newRecord:CKRecord = CKRecord(recordType: "ImageRecord")
        newRecord.setValue(ImageToSave, forKey: "Image")

        if let database = self.privateDatabase {


            database.saveRecord(newRecord, completionHandler: { (record:CKRecord!, error:NSError! ) in

                if error != nil {

               NSLog(error.localizedDescription)

                }


                else {

                    dispatch_async(dispatch_get_main_queue()) {

println("finished")

                }
        })
        }

您需要创建一个 CKAsset 并将其添加到您的记录中。您可以使用如下代码来做到这一点：

func SaveImageInCloud(ImageToSave: UIImage) {
    let newRecord:CKRecord = CKRecord(recordType: "ImageRecord")

    let nsDocumentDirectory = NSSearchPathDirectory.DocumentDirectory
    let nsUserDomainMask = NSSearchPathDomainMask.UserDomainMask
    if let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true) {
        if paths.count > 0 {
            if let dirPath = paths[0] as? String {
                let writePath = dirPath.stringByAppendingPathComponent("Image2.png")
                UIImagePNGRepresentation(ImageToSave).writeToFile(writePath, atomically: true)

                var File : CKAsset?  = CKAsset(fileURL: NSURL(fileURLWithPath: writePath))
                newRecord.setValue(File, forKey: "Image")

            }
        }
    }

    if let database = self.privateDatabase {
        database.saveRecord(newRecord, completionHandler: { (record:CKRecord!, error:NSError! ) in
            if error != nil {
                NSLog(error.localizedDescription)
            } else {
                dispatch_async(dispatch_get_main_queue()) {
                    println("finished")
                }
            }
        })
    }
