[SOLVED] How to create folder for save/get data in iOS by using widget code?
-
Hi,
Aren't you missing a separator ? i.e.
QStandardPaths::writableLocation(QStandardPaths::DataLocation) + "/filename.txt" -

I already tried it and tried it now again. Does not work unfortunately.
The path it gave me (when I used qDebug() << file.fielname) was:
/var/mobile/Applications/262093E8-F9A7-4624-9559-FB3C6BF393E5/Library/Application Support/filename.txt
Maybe the problem is that there is a space between Application and Support? -
No, that should not be a problem. What error do you get from your file ?

Well, the interesting thing is that I get no error, I only see that the data has not been saved after I restarted the app. What path would I use with qrc? Because I also tried it with that => path ":/data/filename.txt", that is the path qt also tells I should take, but this works only if I run it on my mac. Do I have to include something in the .pro file?
-
Just to be sure I understand you correctly, do you want to read a file from qrc and store it on the device ?

yes, but I also like the other version if the data can be saved (sorry my english migth be unclear sometimes, I'm from switzerland)

No no, your english is not that bad, it was just to confirm I understood you correctly.
Since it's on iOS you may have to use the Q_INIT_RESOURCE macro to make your resources accessible.

Ok, I see it should work with that, but what line exactly do I have to add in main.cpp when I have Resources=>data.qrc=>/=>Database.txt or the "normal" path :/Database.txt? Because I tried many lines again and don't know where the error is.
-
IIRC:
Q_INIT_RESOURCE(data);And then you can use the path like normal.

I don't know why, but it works now, I inserted the line in the main.cpp, but used the QStandardPaths::... Thank you very much!

qrc is a read-only system by design. Otherwise it would mean that you can rewrite your executable in place.
You're welcome !
