request"Bytes_processed" => 453489, // The length of the received data"Done" => false, // whether the request is completed. true indicates that the request is completed. false indicates that the request is not completed.
// Information of a single file"Files" => array (0 => array (...),// The same request may contain multiple files1 => array (...),));
In this way, we can use content_length and bytes_processed to get the progress percentage.
Program
1, create a progress bar
Var progressView=UIProgressView(progressViewStyle:UIProgressViewStyle.Default)
progressView.center=self.view.center
progressView.progress=0.5 //default progress 50%
self.view.addSubview(progressView);
2, set the progress, simultaneously has the animation effect
progressview.setp
; 57343257,//POST request
"Bytes_processed" => 453489,//received length of data
"Done" => false,//Request completion True indicates completion, false incomplete
Information for a single file"Files" => Array (0 => Array (...),Multiple files can be included in the same request1 => Array (...),));
In this way, we can use the Content_length and bytes_processed two items to get a progress percentage.
