推荐答案

一个肯定的方式得到一个 NSURL 到应用程序文档目录就是这样...

A surefire way to get an NSURL to the application documents directory is like this...

NSURL *documentsDirectoryURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];

然后你可以得到一个 NSURL 您的声音文件像这样...

Then you can get an NSURL reference to your sound file like this...

NSURL *soundURL = [documentsDirectoryURL URLByAppendingPathComponent:@"sound.caf"];

如果你需要一个字符串表示在那个URL的资源的路径，你可以这样获得...

If you need a string representation of the path to the resource at that URL you can obtain it like this...

NSString *pathRepresentation = [soundURL absoluteString];
