How to process large files using NSData?

Question

I have a very large video and I need to record this video in order to upload it to Dropbox .

I tried to use NSData, but since this file is too large, my application always crashes, so I don’t know what I can do now.

For small videos, I used this:

NSData(contentsOfURL: self.newAsset.URL)!.subdataWithRange(NSMakeRange(0, 10000000))

and I had no problems with this, but when the video is too large, I have an error:

Unable to allocate memory

So what can I do to organize the data of large videos?
