How to determine the size (in bytes) of a file downloading using NSURLConnection?
- by RexOnRoids
I need to know the size of the file I am downloading (in bytes) into my app using NSURLConnection (GET). Here is my bytes recieved code below if it helps. What I need to know is how to get the filesize in bytes so that I can use it to show a UIProgressView.
- (void)connection:(NSURLConnection *)theConnection didReceiveData:(NSData *)data
// A delegate method called by the NSURLConnection as data arrives. We just
// write the data to the file.
{
#pragma unused(theConnection)
NSInteger dataLength;
const uint8_t * dataBytes;
NSInteger bytesWritten;
NSInteger bytesWrittenSoFar;
assert(theConnection == self.connection);
dataLength = [data length];
dataBytes = [data bytes];
bytesWrittenSoFar = 0;
do {
bytesWritten = [self.fileStream write:&dataBytes[bytesWrittenSoFar] maxLength:dataLength - bytesWrittenSoFar];
assert(bytesWritten != 0);
if (bytesWritten == -1) {
[self _stopReceiveWithStatus:@"File write error"];
break;
} else {
bytesWrittenSoFar += bytesWritten;
} while (bytesWrittenSoFar != dataLength);
}
