コードを使用しています
NSArray *directoryNames = [NSArray arrayWithObjects:@"hats",@"bottoms",@"right",@"left",nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
for (int i = 0; i < [directoryNames count] ; i++) {
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:i]];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil]; //Create folder
NSString *folderPath = [documentsDirectory stringByAppendingPathComponent:@"hats"]; // "right" is at index 2, per comments & code
NSString *filePath = [folderPath stringByAppendingPathComponent:@"IMAGE_NAME_HERE.PNG"];
NSData *imageData = UIImagePNGRepresentation(captureImage.image);
[imageData writeToFile:filePath atomically:YES];
