Question

Creating a custom directory which has all the images. Designing it custom because, it will help me to get the images as an when I need at various places in the configuration.

NSFileManager *filemgr;
filemgr = [NSFileManager defaultManager];       
[filemgr createDirectoryAtPath: @"/Users/home/lifemoveson/test" withIntermediateDirectories:YES attributes: nil error:NULL];

I have placed images under test folder and are of .png types.
Is there a way to retrieve the images like below.

/** UPDATED again **/

Currently this folder is under Application_Home/Resources/ImageTiles/ as per Photoscroller example.
How can we change it to /Users/home/lifemoveson/test/ImageTiles/ folder ?

- (UIImage *)tileForScale:(CGFloat)scale row:(int)row col:(int)col
{
// we use "imageWithContentsOfFile:" instead of "imageNamed:" here because we don't want UIImage to cache our tiles
NSString *tileName = [NSString stringWithFormat:@"%@_%d_%d_%d", imageName, (int)(scale * 1000), col, row];

// Currently this folder is under <Application_Home>/Resources/ImageTiles/ as per Photoscroller example. 
// How can we change it to /Users/home/lifemoveson/test/ImageTiles/ folder ?
NSString *path = [[NSBundle mainBundle] pathForResource:tileName ofType:@"png"];
UIImage *image = [UIImage imageWithContentsOfFile:path];
return image;
}

Applications running on iOS are sandboxed; you can’t simply create directories wherever you please. Your createDirectoryAtPath: call will fail. You should use one of the directories set aside for your application instead.

Once you obtain the path for one of those directories, getting the path for files within them is simply a case of using NSString‘s stringByAppendingPathComponent: method.
