选择声音文件+ iPhone SDK

Question

我们可以从iPhone中选择特定长度的声音文件吗？

Answer 1

iPhone apps only have access to files that are stored within the application's own storage area. So, you cannot access the files that the user has loaded into iTunes. You can only view their metadata and cause them to be played.

However, the meta-data of the iTunes library does include length, so you could examine that metadata instead of examining the files, and select ones with a length that you want.
