Get Path to Subdirectory in Resources Folder

问题

i'm trying to get an array of all png files in a subdirectory of the Resources Folder. In my apps Resources Folder I have created a Folder named "images". This folder holds all the png-files I need to display.

This is the way I tried to get the Path:

    NSString *imagepath = [NSString stringWithFormat:@"%@/%@",[[NSBundle mainBundle] bundlePath],@"images/"];

NSLog(@"Path to Images: %@", imagepath);

NSArray * paths = [NSBundle pathsForResourcesOfType: @"png" inDirectory:imagepath];
NSMutableArray * allImageNames = [[NSMutableArray alloc] init];

for ( NSString * path in paths )
{
    if ( [[path lastPathComponent] hasPrefix: @"AQ"] )
        continue;

    [allImageNames addObject: [path lastPathComponent]];
}

This way I get a Path like …/appname.app/images

But if i try to do it that way, the array is always empty. What am I doing wrong?

Just solved it.

NSBundle *mainBundle = [NSBundle mainBundle];
NSArray *pngs = [mainBundle pathsForResourcesOfType:@".png"
 inDirectory:@"random pictures"];

 NSLog(@"pngs in my dir:%@", pngs);

dir structure: "Resources/random pictures".

This works, BUT, when you add the files to 'Resources', you need to check "Create folder references for any aded folders", and NOT "Create groups for any added folders".

Cheers!
