How to save images into specific folder in iOS 9.0

Question

Already have answers, for saving images into specific folder by using ALAssetsLibrary. But it is deprecated in iOS 9.0 and giving warning "Use PHPhotoLibrary from the Photos framework instead".

When i change ALAssetsLibrary into PHPhotoLibrary getting the error at this point.

    [self.library saveImage:image toAlbum:@"myAlbum" withCompletionBlock:^(NSError *error) {
    if (error!=nil) {
        NSLog(@"Big error: %@", [error description]);
    }
}];

*error

 No visible @interface for 'PHPhotoLibrary' declares the selector 'saveImage:toAlbum:withCompletionBlock:'

How to save images into specific folder By Using PHPhotoLibrary (or) any other solutions.

Thank you in advance.

I have not used PHPhotoLibrary yet but I know the old school way of saving photos in Obj-C using the local documents directory:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = paths.firstObject;
NSData *imageData = UIImagePNGRepresentation(image);

NSString *imagePath = [NSString stringWithFormat:@"%@/%@",documentsDirectory,imageFolder];

BOOL isDir;
NSFileManager *fileManager= [NSFileManager defaultManager];
if(![fileManager fileExistsAtPath:imagePath isDirectory:&isDir])
    if(![fileManager createDirectoryAtPath:imagePath withIntermediateDirectories:YES attributes:nil error:NULL])
        NSLog(@"Error: folder creation failed %@", documentsDirectory);

[[NSFileManager defaultManager] createFileAtPath:[NSString stringWithFormat:@"%@/%@", imagePath, imageName] contents:nil attributes:nil];
[imageData writeToFile:[NSString stringWithFormat:@"%@/%@", imagePath, imageName] atomically:YES];

To retrieve that image from the NSDocumentDirectory:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = paths.firstObject;
NSString *fullPath = [NSString stringWithFormat:@"%@/%@", documentDirectory, imagePath]; // image path is same as above
if ([[NSFileManager defaultManager] fileExistsAtPath:fullPath]) {
    UIImage *image = [UIImage imageWithContentsOfFile:fullPath];
    return image;
} else {
    return nil;
}

what is imageFolder ? and imageName ? ...i am using imagePickerController – Chandan Reddy Nov 09 '15 at 09:40
These are strings that you create. imagePickerController will return the image to you as a UIImage out of the delegate methods for the class. You can decide what to do with it from there. – dokun1 Nov 10 '15 at 07:32
Ya got it . We should mention our own folder name and image name right – Chandan Reddy Nov 10 '15 at 08:42
Can you tell me how to fetch saved image from Document Directory – Chandan Reddy Nov 10 '15 at 08:44
@ChandanReddy i will update my answer above shortly. – dokun1 Nov 10 '15 at 14:06
Thank You @dokun1 i will check it. – Chandan Reddy Nov 12 '15 at 05:46
Change line from "NSString *fullPath = [NSString stringWithFormat:@"%@/%@", documentDirectory, imagePath];" to NSString *fullPath = [NSString stringWithFormat:@"%@/%@/%@", documentDirectory, imageFolder,fileName]; because imagePath already have documentDirectory. so it is wrong path. – Chandan Reddy Nov 18 '15 at 09:34

Because there is not Method named like this.

For saving images to the PHPhotoLibrary you need to create an Asset. See

Which PHAssetCollection to use for saving an image?

for detailed informations.
