在共享扩展中使用SVProgressHUD [英] Use of SVProgressHUD in share extension

问题描述

我在iOS应用中使用SVProgressHUD，并且运行良好.我也想将其用于此应用程序的共享扩展名，但它不显示该应用程序. 我正在使用共享扩展视图的自定义视图，这是我用来调用SVProgressHUD的代码.请注意，打印上传进度可以正常进行. 我究竟做错了什么? 谢谢.

I use SVProgressHUD in an iOS app and it's working perfectly. I'd like to use it also for the share extension of this app but it does not show app. I'm using a custom view for the share extension view and here is the code I use to call SVProgressHUD. Note that printing the upload progress works fine. What am I doing wrong? Thanks.

class ShareViewController: UIViewController {
        ...
        Alamofire.upload(multipartFormData: { multipartFormData in
            multipartFormData.append(jpgImageData!, withName: "file",fileName: fname, mimeType: "image/jpg")
            for (key, value) in parameters {
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
            }
        },
                         to:url!)
        { (result) in
            switch result {
            case .success(let upload, _, _):

                upload.uploadProgress(closure: { (progress) in
                    print("Upload Progress: \(progress.fractionCompleted)")
                    SVProgressHUD.setViewForExtension(self.view)
                    SVProgressHUD.showProgress(Float(progress.fractionCompleted))
                })
                upload.responseJSON { response in
                if response.response?.statusCode == 200{
                    if let result = response.result.value {
                        DispatchQueue.main.async(execute: {

                            let pre = NSLocale.preferredLanguages[0]
                            var message = "Message"
                            SVProgressHUD.showSuccess(withStatus: message)
                            SVProgressHUD.dismiss(withDelay: 2)
                            self.extensionContext?.completeRequest(returningItems: nil, completionHandler: nil)
         })      

}

推荐答案

尝试一下

class ShareViewController: UIViewController {
...
Alamofire.upload(multipartFormData: { multipartFormData in
multipartFormData.append(jpgImageData!, withName: "file",fileName: fname, mimeType: "image/jpg")
for (key, value) in parameters {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
}
},
to:url!)
{ (result) in
switch result {
case .success(let upload, _, _):

upload.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress.fractionCompleted)")
 DispatchQueue.main.async(execute: {
SVProgressHUD.setViewForExtension(self.view)
SVProgressHUD.showProgress(Float(progress.fractionCompleted))
})
})
...
}
