[iphone] 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:

• 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.

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);

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"];

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.
