Help: List contents of iPhone application bundle subpath? - iphone

Question

I am trying to get a listing of the directories contained within a subpath of my application bundle. I've done some searching and this is what I have come up with
- (void) contents {
NSArray *contents = [[NSBundle mainBundle] pathsForResourcesOfType:nil
inDirectory:#"DataDir"];
if (contents = nil) {
NSLog(#"Failed: path doesn't exist or error!");
} else {
NSString *bundlePathName = [[NSBundle mainBundle] bundlePath];
NSString *dataPathName = [bundlePathName stringByAppendingPathComponent:
#"DataDir"];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSMutableArray *directories = [[NSMutableArray alloc] init];
for (NSString *entityName in contents) {
NSString *fullEntityName = [dataPathName
stringByAppendingPathComponent:entityName];
NSLog(#"entity = %#", fullEntityName);
BOOL isDir = NO;
[fileManager fileExistsAtPath:fullEntityName isDirectory:(&isDir)];
if (isDir) {
[directories addObject:fullEntityName];
NSLog(#" is a directory");
} else {
NSLog(#" is not a directory");
}
}
NSLog(#"Directories = %#", directories);
[directories release];
}
}
As you can see I am trying to get a listing of directories in the app bundle's DataDir subpath. The problem is that I get no strings in my contents NSArray.
note:
- I am using the simulator
- When I manually look in the .app file I can see DataDir and the contents therein
- The contents of DataDir are png files and directories that contain png files
- The application logic needs to discover the contents of DataDir at runtime
- I have also tried using
NSArray *contents = [fileManager contentsOfDirectoryAtPath:DataDirPathName error:nil];
and I still get no entries in my contents array
Any suggestions/alternative approaches?
Thanks.

I'm not sure what I was doing wrong yesterday but I have this code working:
NSString *bundlePathName = [[NSBundle mainBundle] bundlePath];
NSString *dataPathName = [bundlePathName stringByAppendingPathComponent:#"DataDir"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:dataPathName]) {
NSLog(#"%# exists", dataPathName);
BOOL isDir = NO;
[fileManager fileExistsAtPath:dataPathName isDirectory:(&isDir)];
if (isDir == YES) {
NSLog(#"%# is a directory", dataPathName);
NSArray *contents;
contents = [fileManager contentsOfDirectoryAtPath:dataPathName error:nil];
for (NSString *entity in contents) {
NSLog(#"%# is within", entity);
}
} else {
NSLog(#"%# is not a directory", dataPathName);
}
} else {
NSLog(#"%# does not exist", dataPathName);
}
