Moving the contents of a directory to another directory (iOS) - objective-c

When a user uses my app without logging on I store all the files they create in a directory called default_dir(which contains files and sub-dirs). When they do eventually login in I need to move the files from default_dir to a newly created dir called user_name.
That gives me 2 options.
Rename default_dir to user_name (I can't see anything on NSFilemanager to indicate this is possible).
Or try to somehow copy all the files and dirs into a newly created dir, user_name.
Can you advise how best to proceed in accomplishing this please?
Many Thanks,
-Code

Did you try NSFileManager's -moveItemAtURL:toURL:error: ?

Is there an easy way to move a file to a different folder in dbt Cloud?

Is there an easy way to move a file to a different folder in dbt Cloud, without having to create a new file of the same name in the new folder, copy/paste from the old file, and delete the old file, which is a pain.
Is there a good reason I should NOT do this? I assume my refs still work as long as the filename remains the same, and I don't have any specific folder logic tied to this file.
For example, say I have my_model.sql in my 'staging' folder and I want to simply move it to my 'mart' folder instead. In this example I'd like to do this to reflect that my file is really a more 'stable' mart-type table file vs a staging view. I realize I can just change the materialization type, but I'm doing this more to organize things clearly. Thanks!
The way to move a file in the cloud IDE for dbt is not 100% obvious. You can use the rename function to move a file to another location.
Click on the drop down next to the file name, then select "Rename." That will open a file path and you can change where the file lives from there by typing in the new folder's name.
The easiest way I have found to do this is...not using DBT Cloud, but using github desktop (no command line needed).
Create a new branch
Open repository in github
View files in your file explorer
Move files or directory locally
Upload to github
Push to origin for the branch you created
Open a pull request
Merge
Depending on what the file or directory is you may find the creating a new branch and opening PR to be overkill. For my specific project there is a lot of legacy organization and models that we aren't totally sure don't have downstream dependencies, so creating a new branch for this allowed me to test run all of our models.
Hope this helps!

How to unzip the same zip file multiple times?

I am developing a zip extractor app for which if i unzip multiple times the same zip file it should extract like myfile-1, myfile-2, myfile-3 something like this .
example : there is sampleproject.zip in my desktop when i unzip it should be like sampleproject, sampleproject-1, sampleproject-2.
Any Suggestions.
Thanks in Advance!
Based on your comment I suggest you unzip your file to a temporary directory and then move its contents into the actual directory, handling any name clashes as you do that. In outline:
Use URLForDirectory:inDomain:appropriateForURL:create:error: to create a temporary directory suitable to unzip into. You should pass your the URL of your destinationPath for the appropriateForURL: parameter; this should give you a temporary directory on the same volume as destinationPath making placing the unzipped items into the right place moves rather than copies.
Unzip into the temporary directory returned by (1)
Now use NSFileManager calls to traverse the temporary directory moving each item found to destinationPath, renaming as needed to avoid name clashes.
Remove the temporary directory.
If you have problems implementing this algorithm ask a new question, show your code, explain your problem, and include a link back to this question so the thread can be followed. Someone will then undoubtedly help you with the next step.

Writing to a document's enclosing folder

When you open an XCode project it can automatically write to the enclosing folder of the respective .xcodeproj file.
In a sandboxed application you can only write to files that are opened, or write to directories that have been opened with NSOpenPanel.
What I'm trying to achieve is the same functionality as XCode ; my app makes a project file (a document much like an .xcodeproj file) that is saved to a user-selected directory, and within that directory other files are created relating to that project file. However, if the file is re-opened after terminating the app, I end up losing permission to write to the enclosing directory.
I see bookmarks are an option but they do not provide the same functionality. If the project file is moved to a new directory it makes no sense to keep writing to the old directory, and I'd have to ask the user for permission to write to the new directory. I don't find this user-friendly. Is there absolutely no way to resolve this problem?

Unfortunately for you this is Apple's sandbox model and you need to adapt to it. The process you describe is a good way to handle your situation - when you first create a project file ask the user to select the folder to store it and save a bookmark to that folder, when an existing project file is opened check whether you have a saved bookmark for its parent folder and if not put up a dialog explaining the file has been moved and ask the user for permission to use the new parent folder and keep a bookmark to it.
Users are used to these dialogs from apps, the sandbox has been around a long time. You might find keeping a number of saved bookmarks and optimising your collection will improve your users experience. E.g. remember that a bookmark to a folder grants access to all the files and folders within it, and the files/folders within those folders, etc. This means if a user reorganises by moving projects into sub folders may not require you to ask for a new bookmark, and similarly when a new bookmark is acquired any existing ones you have stored to folders contained by the new bookmark's folder are redundant and can be removed from your collection of stored bookmarks.
Not the answer you really wanted, but hope it helps!

Why Tooltwist Controller deletes or overwrite files in destination server?

When I use the ToolTwist Controller to deploy my application, it deletes or overwrites files configuration files on the destination server that I don't want changed. Is there any way to prevent this?
Yes, there is a way to prevent this. You just need to protect those files or folders that you don't want to be overwritten. To do this, you just need to update the protect property of .fip-destination file found inside ~/server/ folder.
This is the default value:
protect=mysql/.*,tomcat/work/.*,tomcat/logs/.*,protected/.*,tomcat/conf/tomcat-users.xml
Sample customized value:
protect=mysql/.*,tomcat/work/.*,tomcat/logs/.*,tomcat/lib/.*,tomcat/endorsed/.*,tomcat/bin/.*,tomcat/conf/.*,tomcat/webapps/elbhc.*,tomcat/webapps/ttsvr/WEB-INF/.*,protected/.*

Visual Studio 2010 Setup does not create added file

My problem should be plain and simple to solve, but google is not helping me today.
I need to read/write a configuration file (config.xml) and, as i see so much problems with permissions with special folders, i decided for myDocuments.
Now, from File system (Setup), I added a custom special folder (myDocuments)
added a subfolder (g1OKweb) inside myDocuments
added the file (config.xml) inside g1OKweb
What I expect, reading around, is that during the installation g1OKweb should be created if not existing or older, and the same for config.xml, but it isn't.
Does someone have any clue?
Thanks in advance
Use Directory.CreateDirectory to create the directory before attempting to access the file. This will automatically create all parts of the path that do not yet exist. If the full path already exists, it will do nothing.
When opening the file, use a FileStream constructor overload that allows you to specify FileMode.OpenOrCreate. This will succeed regardless of whether the file already exists or not.
When you have opened the file, check to see if it is empty before parsing it. If it is empty, insert your XML root element first.
