以编程方式获取应用程序支持文件夹的路径 [英] Programmatically get path to Application Support folder

问题描述

我正在尝试为用户的应用程序支持文件夹获取 NSString.

I'm trying to get an NSString for the user's Application Support folder.

我知道我可以做到 NSString *path = @"~/Library/Application Support"; 但这似乎不太优雅.我已经尝试过使用 NSSearchPathForDirectoriesInDomains 但它似乎很冗长并且创建了几个不必要的对象(至少，我的实现是这样的).

I know I can do NSString *path = @"~/Library/Application Support"; but this doesn't seem very elegant. I've played around with using NSSearchPathForDirectoriesInDomains but it seems to be quite long-winded and creates several unnecessary objects (at least, my implementation of it does).

有没有简单的方法可以做到这一点?

Is there a simple way to do this?

推荐答案

这已经过时了，对于当前的最佳实践，请使用 FileManager.default.urls(for:in:) 作为评论中的 @andyvn22 下面.

This is outdated, for current best practice use FileManager.default.urls(for:in:) as in the comment by @andyvn22 below.

最佳实践是使用 NSSearchPathForDirectoriesInDomains 和 NSApplicationSupportDirectory 尽可能冗长".

the Best practice is to use NSSearchPathForDirectoriesInDomains with NSApplicationSupportDirectory as "long winded" as it may be.

示例:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES);
NSString *applicationSupportDirectory = [paths firstObject];
NSLog(@"applicationSupportDirectory: '%@'", applicationSupportDirectory);

NSLog 输出:

applicationSupportDirectory: '/Volumes/User/me/Library/Application Support'
