推荐答案

听起来您正在直接将文件下载到内存中.这将是一个问题，因为您没有足够的内存来下载整个文件.

It sounds like you're downloading the files straight to memory. That will be an issue because you wont have enough memory to download the entire file.

您需要采取的策略是，在下载文件时，继续将文件的一部分写到磁盘上，从而释放内存.

The strategy you need to take is, as you download the file continue to write chunks of it out to disk, freeing up memory in doing so.

如果您使用的是NSURLSession，则可以使用一个参数轻松完成此操作.请发布您的代码以获取深入帮助.

If you are using NSURLSession there is a parameter you can use to do this for you with little effort. Please post your code for in depth help.
