Downloading a Large File - iPhone SDK

Question

I am using Erica Sadun\'s method of Asynchronous Downloads (link here for the project file: download), however her method does not work with files that have a big size (50 m

Answer 1

Try AFNetworking. And:

NSString *yourFileURL=@"http://yourFileURL.zip";
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:yourFileURL]];
AFURLConnectionOperation *operation =   [[AFHTTPRequestOperation alloc] initWithRequest:request];

NSString *cacheDir = [NSSearchPathForDirectoriesInDomains
                          (NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [cacheDir stringByAppendingPathComponent:
                      @"youFile.zip"];

operation.outputStream = [NSOutputStream outputStreamToFileAtPath:filePath append:NO];

[operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {
   //show here your downloading progress if needed
}];

[operation setCompletionBlock:^{
    NSLog(@"File successfully downloaded");
}];

[operation start];
