Working with paths from [[NSBundle mainBundle] resourcePath]
提问by Tom Irving
I'm sure it's a very basic problem, but I'm having trouble finding anything about it.
我敢肯定这是一个非常基本的问题，但我很难找到有关它的任何信息。
Say I've got my app in a folder, in some more folders, like this:
假设我将我的应用程序放在一个文件夹中，在更多文件夹中，如下所示：
- MainFolder > SecondaryFolder > AppBundle.app > all the stuff
- MainFolder > SecondaryFolder > AppBundle.app > 所有的东西
Then, what I want to do is access a file that is in the "MainFolder". I know I can get the path of the AppBundle by using:
然后，我想要做的是访问“MainFolder”中的文件。我知道我可以使用以下方法获取 AppBundle 的路径：
NSLog(@"%@",[[NSBundle mainBundle] resourcePath]);
NSLog(@"%@",[[NSBundle mainBundle] resourcePath]);
What I'm uncertain about is how to get the path of the "MainFolder".
我不确定的是如何获取“MainFolder”的路径。
Any pointers would be great!
任何指针都会很棒！

I'd use -[NSString stringByDeletingLastPathComponent]twice.
我会用-[NSString stringByDeletingLastPathComponent]两次。
NSString *bundlePath = [[NSBundle mainBundle] resourcePath];
NSString *secondParentPath = [[bundlePath stringByDeletingLastPathComponent] stringByDeletingLastPathComponent];

I use:
NSString *mainBundlePath = [[NSBundle mainBundle] bundlePath];
我用：
NSString *mainBundlePath = [[NSBundle mainBundle] bundlePath];
