在我的视图控制器中,我有以下方法上传文件.

func uploadToS3(){    // get the image from a UIImageVIEw that is displaying the selected Image    var img: UIImage = imageVIEw.image!    // create a local image that we can use to upload to s3    var path: Nsstring = NstemporaryDirectory().stringByAppendingPathComponent("image.png")    var imageData: NSData = UIImagePNGRepresentation(img)    imageData.writetofile(path as String,atomically: true)    // once the image is saved we can use the path to create a local fileurl    var url:NSURL = NSURL(fileURLWithPath: path as String)!    // next we set up the S3 upload request manager    let uploadRequest = awss3transfermanagerUploadRequest()    // set the bucket    uploadRequest?.bucket = "test-bucket"    // I want this image to be public to anyone to vIEw it so I'm setting it to Public Read    uploadRequest?.ACL = AWSS3ObjectCannedACL.PublicRead    // set the image's name that will be used on the s3 server. I am also creating a folder to place the image in    uploadRequest?.key = "foldername/image.png"    // set the content type    uploadRequest?.ContentType = "image/png"    // and finally set the body to the local file path    uploadRequest?.body = url;    // we will track progress through an AWSNetworkingUploadProgressBlock    uploadRequest?.uploadProgress = {[uNowned self](bytesSent:Int64,totalBytesSent:Int64,totalBytesExpectedToSend:Int64) in        dispatch_sync(dispatch_get_main_queue(),{ () -> VoID in            println("total  bytes sent")            println(totalBytesSent)            println("total  bytes expected to send")            println(totalBytesExpectedToSend)        })    }    // Now the upload request is set up we can creat the transfermanger,the credentials are already set up in the app delegate    var transferManager:awss3transfermanager = awss3transfermanager.defaultS3TransferManager()    // start the upload    transferManager.upload(uploadRequest).continueWithExecutor(BFExecutor.mainThreadExecutor(),withBlock:{ [uNowned self]        task -> AnyObject in        // once the uploadmanager finishes check if there were any errors        if(task.error != nil){            println("%@",task.error);        }else{ // if there aren't any then the image is uploaded!            // this is the url of the image we just uploaded            println("https://s3.amazonaws.com/s3-demo-swift/foldername/image.png");        }        //self.removeLoadingVIEw()        println("all done");        return ""        })}

对于任何想要重新创建此应用程序的人

添加到您的Podfile：

pod 'AWscore'pod 'AWSS3'pod 'AWSiOSSDKv2'pod 'AWSCognitoSync'

然后添加包含以下内容的桥接头

#import <AWscore/AWscore.h>#import <AWSS3/AWSS3.h>

在我的AppDelegate中,我有：

func application(application: UIApplication,dIDFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {            // OverrIDe point for customization after application launch.    AWSCognitoCredentialsProvIDer.initialize()    var credentialsProvIDer = AWSCognitoCredentialsProvIDer(        regionType: AWSRegionType.USEast1,IDentityPoolID: "IDentity pool ID"    )    var configuration = AWSServiceConfiguration(        region: AWSRegionType.USEast1,credentialsProvIDer: credentialsProvIDer    )    AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration    return true}

最后,在包含uploadToS3()的视图控制器中,添加import AWSS3.

更新

这是记录错误的最后一部分.

我的问题是,如何解决这个问题并成功上传图片.

解决方法 如错误消息所述,您的Amazon Cognito IDentity池未正确设置权限. Understanding Amazon Cognito Authentication博客系列( Part 2,Part 3)和 Amazon Cognito Developer Guide是您理解和设置Cognito IDentity的绝佳资源. 总结
