i make a localized iphone application and in run time i want to modify the property list, so i at the first run of the application i copied the plist file but i don't sure if the copy operation also copied the localized version which the system store in a folder like: lp.fr
my quetion is: what i must do for the system to recognise the two files? should i make two directory in documents folder like lp.en and lp.fr and copy the two files?
also also xcode make the two plist with the same name, how i can determine every version and copy it?
i am waiting for some one to direct me to write way.
thanks
Take a look at NSBundle's pathForResource:ofType. It clearly states that it will return a non localized file if it exists or else pick a file in the order of user's language preferences. As you wan't to copy a localized resource, don't create a non localized copy and this will return the path for the most suitable resource. You can just copy that file and make changes to it.
If you are interested in getting the path to a resource of a specific language, take a look at pathForResource:ofType:inDirectory:forLocalization.

How do you go about creating files at arbitrary locations given you have the absolute path? I want to create a file in some arbitrary location /Users/me/random/project3/<moreStuffInThePath. How would I go about doing this?
To create a directory I would do:
try FileManager.default.createDirectory(atPath: "/Users/me/random/project3/<directoryName>"
This worked fine for directories.
However the counterpart for creating files does not work:
FileManager.default.createFile(atPath: "Users/me/random/project3/something.txt", contents: someString.data(using: .utf8)) // always returns false
I have checked out other stack overflow threads on creating files. Everything I found was about creating files in the .documentDirectory or it was outdated.
Eg: How to create text file for writing
Create empty file swift
Read and write a String from text file
TLDR: How do I create text files/files with random extensions at arbitrary locations on the pc given I have the absolute path?
I would also be grateful if someone could explain why all tutorials available on this matter are about the document directory. Why is it so significant?
Thank you!
This is most likely because your app is sandboxed.
Go to your project settings, select the macOS target and go to "Signing and Capabilities". You should see something like this:
If your app needs to create files in arbitrary locations, you must remove the app sandbox by clicking on the "x" on the top right. Note that this will cause your app to be rejected from the Mac App Store.
If you want to upload your app to the Mac App Store, then you must keep the sandbox, and write to "user selected locations" only. Select "Read/Write" rather than "Read Only" next to "User Selected File". (Although it says "File", this includes directories too) This allows you to write to locations chosen by a user using something like an NSSavePanel.
How can we make a nested directory in resource folder to put the xmls with same name for different folders.And how we can read it using path in iphone app programatically?
Actually i want to make like resource>a>b>some.xml
again in resource like resource>f>g>some.xml
and so on...how ever both xml is containing different data in it.and also tell me the way how we can read it in iphone application.
You cannot use the same filename, even if they resides in different folders.
Instead, as a workaround, you can name the files like:
a_b_some.xml
f_g_some.xml
you can create a folder structure on your system and then directly add the folder to your XCode Project under resources by drag-drop.
this folder must display in BLUE color (physical grouping in folder on disk) rather than YELLOW (logical grouping in project only) just like native folders on mac. like this you can put same file in different folder hierarchy without any problems.
you need to create a absolute path to your file whenever you want its access your file [NSBundle pathForResource:] will not work in this case as it does not have access to your custom folder hierarchy.
best of luck.
I'm looking for a good way to manage many image files in my app.
When the number of images to maintain gets large, it seems vital to have a directory structure to hold them.(to organize images and to support duplicate image names)
Since normal way of storing images in documents directory(by adding images to xcode's resource folder) doesn't seem to support directory structure,
I probably need to use something called bundle.
Here are questions.
It's not clear to me what's the difference between "documents
directory" and "bundle". Are they
just names to specify directory path
inside an iphone application? Since
documents directory doesn't support
directory structure, I guess it's not
a regular file path in iOS? (I'm
looking for a definition or overview
description on those two terms enough
to help answering the following
questions)
How do I create a tree structure directory to store resources?
How do I add files to the created directory?
What is the step (probably in xcode) to add new files to the
directory as project grows? note:
question 3 deals with initial set up,
4 deals with update.
What happens to files under documents directory and bundle when
user updates the app? Since many
applications store user data
somewhere, there must be a way of
updating an app without wiping out the
saved user data. ie. How does
"documents directory" and "bundle"
behave in update situation?
So called "resource bundle" refers to the "bundle" used in above
questions?
Thank you.
Your app is a "bundle". It's represented by an NSBundle object. On iOS, this is the only bundle you are allowed to use; you can't create another bundle and import it into your app.
However, you can add a subdirectory to your app's bundle. In Xcode 4, select your project in the navigator and click on the Build Phases tab. Add a new build phase (bottom right), Copy Files. Move it up just below Copy Bundle Resources, and rename it something meaningful ("copy interface images", or something). You'll notice you've got a Subpath field there - that's your directory in your bundle. Drag the files you want in that subdirectory on to this build phase, and then you can access them through the normal methods in NSBundle, UIImage, NSData and so on.
Wish it was easier? Me too.
I have an .xml file that is going to be shipped within my app.
This file contains values that are read from it and saved as an array when the app launches.
Each time the app is run, I want to check with the server if there is an internet connection. If so, I want to get the newest version of the .xml file from the server and replace the one that I currently have saved in my app (this way, the next time the user logs in and doesn't have internet access, he/she will be able to use the old (yet most up to date) data).
What is the best way to do this?
Thanks,
The best way to probably do this is to copy the XML file from the app bundle to a location in the app's sandbox, e.g. the Documents folder. Thereafter you can update the XML content as necessary with newer data from the server. The copy is necessary to allow you to write to the file, since you cannot change the content of your app's bundle because it is signed.
Alternatively, if the data is simple enough, you can just save it to user defaults on first launch and change the defaults on subsequent updates
I might skip the XML altogether, unless it contains a baseline of default settings, and just sync user defaults over the Internet. You can't modify files in the bundle, so your only option would be to copy over a "default-settings" XML file to the application's Documents folder to make it editable.
I am working on one multilanguage project which will download string from server depend on language selected by user. I would like to save this downloaded string into localizable.string file. So how could I do that? I know how genstrings works but I would like to generated *.strings file by code and save it. My code will read this *.strings file for localizable. Anybody know which api i have to use?
thanks in advance

Typically, localization depends on strings files that are within the app bundle. Since you can not modify the app bundle at run time, you will have to put the strings files you downlaod elsewhere and you will have to modify the usual localization methods to find and use those strings files.
Look at Apple's iPhone samples to see how they do localization and fetching of the strings, and see if you can replace all the local accesses of the localization resources with resources in another directory.
