Progress bar while downloading files iOS

Question

I am using the following to download the files from the internet:

NSData *myXMLData1 = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@\"Link]];

Answer 1

I would recommend looking into the ASIHTTP library, which contains a lot of usefull classes on mobile handling and download handling.

Here is a link where they describe what ASIHTTP can offer in terms of download progress tracking : http://allseeing-i.com/ASIHTTPRequest/How-to-use#progress

Answer 2

add

expectedBytes = [response expectedContentLength];

to

-(void)connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse*)response

and add

float progress = ((_bytesReceived/(float)_expectedBytes)*100)/100;

to

-(void)connection:(NSURLConnection*)connection didReceiveData:(NSData*)data

then setProgress: on your UIProgressView
