我正在尝试将图像上传到存储桶S3 AWS,我正在使用以下代码.但我是否使用它上传到存储在变量或imageView.image中的图像？

let ext = "jpg"
    let imageURL = NSBundle.mainBundle().URLForResource("imagename", withExtension: ext)
    print("imageURL:\(imageURL)")

    let uploadRequest = AWSS3TransferManagerUploadRequest()
    uploadRequest.body = imageURL
    uploadRequest.key = NSProcessInfo.processInfo().globallyUniqueString + "." + ext
    uploadRequest.bucket = S3BucketName
    uploadRequest.contentType = "image/" + ext


    let transferManager = AWSS3TransferManager.defaultS3TransferManager()
    transferManager.upload(uploadRequest).continueWithBlock { (task) -> AnyObject! in
        if let error = task.error {
            print("Upload failed ? (\(error))")
        }
        if let exception = task.exception {
            print("Upload failed ? (\(exception))")
        }
        if task.result != nil {
            let s3URL = NSURL(string: "http://s3.amazonaws.com/\(self.S3BucketName)/\(uploadRequest.key!)")!
            print("Uploaded to:\n\(s3URL)")
        } …

我正在尝试从服务器获取 json 并对其进行反序列化，但我尝试使用未转义的控制字符进行探测。我的代码如下...

let urlFinal = "http://000.0000.000.000:8080"
        let jsonUrl = urlFinal
        let session = NSURLSession.sharedSession()
        let shotsUrl = NSURL(string: jsonUrl)

        let task = session.dataTaskWithURL(shotsUrl!) {data, response, error in
            guard data != nil else {
                falha()
                return
            }

            //let json = JSON(data: data!)
            //print(json["ServicoCliente"][0]["id"])

            do {
                let jsonData = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers )
                let J = jsonData as! NSDictionary
                print(jsonData)
                let us = J["ServicoCliente"]
                print(us)
                dispatch_async(dispatch_get_main_queue(),{
                    sucesso()
                });
            } catch _ {
                falha()
            }
        }
        task.resume()

我也使用 Alamofire 3.0 尝试过这个： …

我需要为我的tableview创建一个自定义标题.为此我创建了一个UITableViewHeaderFooterView类的类,但我无法在故事板上选择tableview的标题来设置类.如果它是一个静态表头,但它对动态表不可见.我该怎么做这个设置？

注意:我使用xcode 7.3.1

我正在尝试这样做,但是故事板:https: //github.com/jeantimex/ios-swift-collapsible-table-section

override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let header = tableView.dequeueReusableHeaderFooterViewWithIdentifier("header") as! NovaListaTableViewHeader


    header.titleLabel.text = sections[section].name
    header.arrowLabel.text = ">"
    header.setCollapsed(sections[section].collapsed)

    header.section = section
    header.delegate = self

    return header
}
