How Do You Change AFNetworking Request's Temporary FilePath

Question

I'm trying to migrate our ASIHTTPRequest code to AFNetworking. I'm okay with POST requests but I'm having issues with download requests. I can't seem to set the temporary file path of the content to be downloaded. In ASIHTTPRequest I can have a code like this:

    // Create file path
    NSString *filePath = [cachePath stringByAppendingPathComponent:package.fileName];
    NSString *tempFile = [tempPath stringByAppendingPathComponent:package.fileName];

    [downloadRequest setTemporaryFileDownloadPath:tempFile];
    [downloadRequest setDownloadDestinationPath:filePath];

How can I do this using AFNetworking?

Answer 1

AFURLSessionManager* urlSessionManager = [AFURLSessionManager.alloc initWithSessionConfiguration:NSURLSessionConfiguration.defaultSessionConfiguration];
NSProgress* progress = nil;
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://your.remote.file"]];
NSURLSessionDownloadTask* downloadTask = [urlSessionManager downloadTaskWithRequest:request progress:&progress destination:^NSURL* (NSURL* targetPath, NSURLResponse* response) {
    NSURL* targetFileUrl = [NSURL fileURLWithPath:@"/your/local/path" isDirectory:NO];
    return targetFileUrl;
} completionHandler:^(NSURLResponse* response, NSURL* filePath, NSError* error) {
    if (error)
    {
        // Some error occurred or download programmatically cancelled
    }
    else
    {
        // Download completed
    }
}];
[downloadTask resume];

The temporary files are managed by AFNetworking, usually they're hidden raw files inside your document dir.
