Download large files

I am currently developing an application that should show offline videos that need to be downloaded first.

The problem was that these videos may be larger than the memory that I can allocate for my application. Therefore, the loaded parts should be immediately saved, not saved in the NSData object. I hear conflicting stories about whether RESTKit should work, and ASIHTTPRequest seems to be out of date.

I will follow the suggestion from this thread as it seems to be the best option.

NSURLConnection download large file (> 40MB)

Consider using NSURLConnection to upload a video file and write data directly to a file ( NSFileHandle ).

One of the advantages of using this method is that the delegate method NSURLConnection didReceiveData constantly called when data is received, so you can update the progress bar.

Check out AFNetworking for network management. I'm not sure if they have video downloads, but the structure works great for images and other types of downloads that I had before.

Without explaining all the hashes with handling HTTP responses in chunks and streams, I would recommend using AFDownloadRequestOperation . It supports resuming downloads and has callbacks to show downloads. I love it and use it in most of my projects.

PS It uses AFNetworking , which is an excellent basis for creating all kinds of HTTP requests.
