How to get file path in iPhone app

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:

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.

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.

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 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.
