Array of NSStrings from filenames within a folder? - iphone

Question

I'm trying to create an array of NSStrings of the contents of a folder that I've dragged into my project... but when I count the items in the array afterwards, it's always comes back with 0;
So, my folder in my project looks like this
-Cards
-Colors
Blue.png
Green.png
Orange.png
Yellow.png
Purple.png
Black.png
And my code which tries to get this list of files (the color pngs) is
NSError *error = nil;
NSString *pathString = [[NSString alloc] init];
pathString = [[NSString alloc] initWithString:#"/Cards/Colors/"];
NSArray *fileList = [[NSArray alloc] init];
fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:pathString error: &error];
[pathString release];
NSLog(#"%#", error);
// this is always 0
NSLog(#"file list has %i items", [fileList count]);
The NSError I get is
Error Domain=NSCocoaErrorDomain Code=260 "The operation couldn’t be completed. (Cocoa error 260.)" UserInfo=0x596db00 {NSUserStringVariant=(
Folder
), NSFilePath=/Cards/Color/, NSUnderlyingError=0x5925ef0 "The operation couldn’t be completed. No such file or directory"}
Any ideads where I am going wrong?

You're initializing pathString to the absolute path /Cards/Colors/. This path is a system-wide path, so on the iPhone, far outside your app's sandbox.
Try this instead:
NSString *pathString = [[NSBundle mainBundle] pathForResource:#"Cards/Colors" ofType:nil];
NSArray *fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:pathString error: &error];
(Note that the way you have your code in the question, you alloc/init fileList, then immediately leak the object by assigning to it the results of contentsOfDirectoryAtPath:error:. This is a bug.)
