如何通过Qt5获取ios文档/库路径？

Question

I used find my ios app's document/library path by going up starts from QApplication::applicationDirPath() .

However from iOS 7/8, the bundle path is moved away from data path.

So how can I get my app's writable paths through Qt C++ only? Is there a correct way that packed with Qt?

I don't want to write on APPROOT 's document. And I understand that I can write objective-c codes to find the path.

So my app is installed at:

/var/mobile/Containers/Bundle/Application/XXXX/

What I want to get is

/var/mobile/Containers/Data/Application/YYYY/Documents

/var/mobile/Containers/Data/Application/YYYY/Library

note that the bundle's long id (the XXXX) is different from Data's (the YYYY)

If you need to take the document or any other standard library directories path, use QStandardPaths from Qt5 :

QStandardPaths::AppDataLocation

For other paths consider to read the official Qt docs about QStandardPaths
