How to use NSURLRequest / NSURLConnection to download an mp3 file to app?
提问by RexOnRoids
The Situation
In my app, I am currently downloading an mp3 file (to docs directory) using [NSData dataWithContentsOfURL:URL]
, a method that works fine, but ties down the CPU, dissallowing screen updates of download status. So, I want to download using a different method so that I can update the screen WHILEdownloading to alert the user that the download has begun.
情况
在我的应用程序中,我目前正在使用 下载一个 mp3 文件(到 docs 目录)[NSData dataWithContentsOfURL:URL]
,这是一种工作正常的方法,但会占用 CPU,不允许屏幕更新下载状态。所以,我想用不同的方法,这样我可以更新屏幕下载WHILE下载到提醒用户下载已经开始。

Use "NSURLConnection asynchronously" search for the term and you'll find source. Or just NSURLConnection.
使用“NSURLConnection asynchronously”搜索该术语,您将找到来源。或者只是 NSURLConnection。
For example:
例如:
