获取iOS应用程序的“〜/ Library”可靠的路径 [英] Getting an iOS application's "~/Library" path reliably

问题描述

苹果技术说明：

http://developer.apple.com/library/ios/#qa/qa2010/qa1699.html

建议储存位于〜/ Library 之外的子目录中的internal用户文档。但我无法找到一个预先创建的搜索域，这将使我这个。什么是最好的/最正确的/最不可能打破这种路径的方式？

谢谢。

解决方案

正确的方法是

  NSString * path; 
 path = NSSearchPathForDirectoriesInDomains（NSLibraryDirectory，NSUserDomainMask，YES）[0]; 
  

然而， [@〜/ LibrarystringByExpandingTildeInPath]




Swift 3：



  let path = NSSearchPathForDirectoriesInDomains（.libraryDirectory，.userDomainMask，true）[0] 
  




This Apple tech note:

http://developer.apple.com/library/ios/#qa/qa2010/qa1699.html

suggests storing "internal" user documents in a subdirectory off of ~/Library. But I can't find one of the pre-created search domains that would get me this. What's the best/most correct/least likely to ever break way of constructing this path?

Thanks.

解决方案

The correct way is

NSString* path;
path = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES)[0];

However, [@"~/Library" stringByExpandingTildeInPath] also works.

---

Swift 3:

let path = NSSearchPathForDirectoriesInDomains(.libraryDirectory, .userDomainMask, true)[0]
