Load files from folder - objective-c

I'm loading a folder with files using this method:
NSString *pngPath = [NSHomeDirectory() stringByAppendingPathComponent:#"GBC/Caras/"];
fotosJugadores = [[NSFileManager defaultManager] contentsOfDirectoryAtPath: #"/Users/exular/Developer/GBC/exular/GBC/Caras/" error: &error];
But the problem remains to get the same functionality to do it once the app will run in the device, how can I set a folder with all that images to be available in the device? Is there any bundle method similar to contentsOfDirectoryAtPath: to load images from project bundle, something like imageNamed: ?
thanks

Is there any bundle method...
When you start a question like that, the answer is usually found in the NSBundle class reference. In this case, the answer is yes, there is such a method. You will see that if you read the documentation. You should always check the documentation before asking for help.

Get list of files in Library folder with sandbox in cocoa

I'm trying to get list of files in Library folder in cocoa, i use this code and NSHomeDrirectory() function without sandboxing and work well.
TempArray = [[NSFileManager defaultManager] directoryContentsAtPath:FolderURL]
but when I checked sandbox is code not work, Is it any entitlements should i add? or what code can replace?
I haven't tried if this will get all the files but it should since you can save and read files from the library.
NSString *libraryPath = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSArray *libraryContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:libraryPath error:nil];
If you add below entitlement you can access ~/Library or /Library folders
com.apple.security.temporary-exception.files.home-relative-path.read-write: /Library/
But after this you will get reply from apple is
2.31:Apps that are not sandboxed appropriately may be rejected
I didn't get answer of this. If anyone knows please post here.

how to get the full path of an ios application? [duplicate]

I have a problem accessing my files in my app.
I am currently using
//Directly from TileMap example from WWDC2010
NSString *tileDirectory = [[[NSBundle mainBundle] resourcePath]
stringByAppendingPathComponent:#"Tiles"];
to access my tiles for my MKOverlay. This gives me this directory
/Users/xxxx/Library/Application Support/iPhone Simulator/4.2/Applications/9D62025C-C53B-472C-8309-xxxx/xxxx.app/Tiles
The x's is only for privacy reasons
I have my tiles in a folder called Tiles in the root of my application which is in Xcode in a group called Tiles which is in directly in the Resources group.
When I run my app, I get a simple error saying that it could not find my tiles at the generated directory (the one quote above) If I replace that piece of code and make it:
NSString *tileDirectory = #"/Users/xxxx/Documents/xxxx/Tiles";
Then my app works fine. This is obviously because it finds my tiles in its direct location on my Mac. This is fine for testing, but I need it to work on my iPhone/iPad.
This problem might be occurring due to:
The generated directory is incorrect.
The tile images aren't getting included in the builded .app file.
Either way, I have no clue of what to do to solve it.
How can I solve this problem?
[EDIT]
I changed that piece of code to:
NSString *tileDirectory = [[NSBundle mainBundle] resourcePath];
Now it works in simulator, because all files are in the apps root folder and I don't ask for it to enter another directory called "Tiles".
This runs with no error on the simulator, but when on my iPhone it gives the original error (just a different file path but also ending with /xxxx.app
How can I ensure a directory in my app file such as xxxx.app/Tiles - TileMap does this.
Since it is your files in your app bundle, I think you can use pathForResource:ofType: to get the full pathname of your file.
Here is an example:
NSString* filePath = [[NSBundle mainBundle] pathForResource:#"your_file_name"
ofType:#"the_file_extension"];
Remember that the "folders/groups" you make in xcode, those which are yellowish are not reflected as real folders in your iPhone app. They are just there to structure your XCode project. You can nest as many yellow group as you want and they still only serve the purpose of organizing code in XCode.
EDIT
Make a folder outside of XCode then drag it over, and select "Create folder references for any added folders" instead of "Create groups for any added folders" in the popup.
If your tiles are not in your bundle, either copied from the bundle or downloaded from the internet you can get the directory like this
NSString *documentdir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *tileDirectory = [documentdir stringByAppendingPathComponent:#"xxxx/Tiles"];
NSLog(#"Tile Directory: %#", tileDirectory);
You need to use the URL for the link, such as this:
NSURL *path = [[NSBundle mainBundle] URLForResource:#"imagename" withExtension:#"jpg"];
It will give you a proper URL ref.
You need to add your tiles into your resource bundle. I mean add all those files to your project make sure to copy all files to project directory option checked.

iCloud not work after update

At the stage of testing applications iCloud works fine. But after the application checks for updates from apple and download from itunes, icloud is not working, then there is a line
NSURL * returnedURL = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier: nil];
returns nil.
Where did I go wrong?
Thanks in advance.
Are you sure your containers are listed in the com.apple.developer.ubiquity-container-identifiers entitlement?
Apple's Documentation on NSFileManager URLForUbiquityContainerIdentifier: mentions:
If you specify nil, this method returns the first container listed in the com.apple.developer.ubiquity-container-identifiers entitlement.

iPad Text File Importing

I'm trying to import a text file into my iPad application using the method initWithContentsOfFile:encoding:error:, but when I try to get the filepath to my text file, I am running into some troubles. It seems that my text file is not being found. The following call returns nil (the text file is called legal.txt)
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"legal"
ofType:#"txt"];
Obviously, after this returns nil, my call...
NSString *fileContents = [[NSString alloc] initWithContentsOfFile:filePath
encoding:NSUTF8StringEncoding
error:#"error"];
also returns nil.
I am quite new at this so I might be doing something obviously incorrect, but looked all over SO and elsewhere and couldn't find anyone with the same problem as me.
Call pathForResource:ofType:inDirectory:
by passing the directory as well
Look in your app target's Copy Resources build phase and make sure legal.txt is making it into your app bundle. You can also look inside the compiled app package in your build folder (~/Library/Developer/Xcode/DerivedData/AppName-.../ by default in Xcode 4).

How do I load a string table from outside application bundle on iOS?

I would like to know how to load a resource string table from a file in application documents and not from application resource bundle or any other bundle.
Do you mean something like
NSString *path = [[NSBundle mainBundle] pathForResource:#"fileName" ofType:#"fileExtension"];
that will get you the path to the file fileName.fileExtension from the app bundle...
There is NSLocalizedStringFromTableInBundle method which means you would have to put the string table in a NSBundle. Theory would be that you could download this NSBundle from the internet. Before you load your MainView Controller, you would load a controller that would check to make sure it has the latest version in NSApplicationSupportDirectory.
This NSBundle cannot contain any binary code because it's against Apple App Store policy to download code in any way or form.
