How to get file path in iPhone app

Question

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

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

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

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

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
