问题描述
我无法在 Apple iOS SDK 上找到有关哪些目录可写以及哪些目录不适用于您的应用程序的信息.
I was not able to find on Apple iOS SDK information regarding which directories are writable and which are not for your application.
我只假设 NSCachesDirectory 和 NSDocumentDirectory 是可写的，但其他的呢，比如 NSApplicationSupportDirectory 或 NSTemporaryDirectory.
I only assume that NSCachesDirectory and NSDocumentDirectory are writable but how about others, like NSApplicationSupportDirectory or NSTemporaryDirectory.
在哪里可以找到通用目录的完整列表以及它们的用途以及它们是否可由我的应用程序写入?
Where can I find a complete list of common directories with their purpose and if they are writable or not by my application?
我能够找到 NSSearchPathDirectory 枚举的可能值，但它们不包含任何有关其用途的信息，如果您能够写信给它们，则更重要.
I was able to locate possible values for NSSearchPathDirectory enum but they do not contain any information regarding their purpose and more important if you are able to write to them.
