NSURLRequest get pdf size

Question

I have a UIWebview that loads a PDF with NSURLRequest. It will load the PDF, but if the pdf is too large the app crashes. I don't receive a memory warning. Is there a way to get the size of the PDF before I download it? Here is how I am loading it: NSURLRequest *currentRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:myUrlString]]; JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

I think you should try to user NSURLMutableRequest instead in case of downloading large file so you can obtain multi-part downloading. You can also use the method expectedContentLength of NSURLResponse to know the file length. Here is an example : - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse*)response { NSLog (@"%d", [response expectedContentLength]); } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { if (self.currentDownloadedFile) { [self.currentDownloadedFile seekToEndOfFile]; [self.currentDownloadedFile writeData:data]; } } - (void)connectionDidFinishLoading:(NSURLConnection*)connection { // Close the file here } And force UIWebView open that downloaded file instead of downloading from un URL.
