Add NSURLConnection loading process on UIProgressView

Question

I created a UIProgressView. But i used NSTimer to UIProgressView\'s process . Now I need to integrate UIProgressView pro

Answer 1

In your didReceiveResponse function you could get the total filesize like so: _totalFileSize = response.expectedContentLength;.

In your didReceiveData function you can then add up to a total bytes received counter: _receivedDataBytes += [data length];

Now in order to set the progressbar to the correct size you can simply do: MyProgressBar.progress = _receivedDataBytes / (float)_totalFileSize

(either in the didReceiveData function or somewhere else in your code)

Don't forget to add the variables that hold the number of bytes to your class!

I hope this helps..

EDIT: Here's how you could implement the delegates in order to update progressview

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
    _totalFileSize = response.expectedContentLength;
    responseData = [[NSMutableData alloc] init];
}


-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
   _receivedDataBytes += [data length];
   MyProgressBar.progress = _receivedDataBytes / (float)_totalFileSize;
   [responseData appendData:data];
 }
