How to access a directory

I would like to save image in a folder. I already the code. to download and save image but I would like to know how to find the path of ma folder ! I create a directory in xcode but the images don't find it and there aren't image in it. So, I would like to save images in "img_bkgrd" folder. enter image description here

[UIImageJPEGRepresentation(image, 1.0) writeToFile:[directoryPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@", imageName]] options:NSAtomicWrite error:nil];

to use the image I use this method:

-(UIImage *) loadImage:(NSString *)fileName inDirectory:(NSString *)directoryPath{
 UIImage * result = [UIImage imageWithContentsOfFile:[NSString stringWithFormat:@"%@/%@", directoryPath, fileName]];
 return result;

}

Can you send me the correct path ? thanks

You can't save the images there. First of all, this is not actually a folder. It is called a group. It is a part of application bundle, which is readonly. You need to save data into Documents directory. Something like that:

NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *imageFolderPath = [documentsDirectory stringByAppendingPathComponent:@"/img_bckr"];

if (![[NSFileManager defaultManager] fileExistsAtPath:imageFolderPath])
     [[NSFileManager defaultManager] createDirectoryAtPath:imageFolderPath withIntermediateDirectories:NO attributes:nil error:&error];

NSString* imagePath = [imageFolderPath stringByAppendingPathComponent:@"MyImage"];

[UIImageJPEGRepresentation(image, 1.0) writeToFile:imagePath options:NSAtomicWrite error:nil];

You may store imagePath somewhere or build it later based upon file name and then simply:

UIImage* img = [UIImage imageWithContentsOfFile:imagePath];
