UIImage Saving image with file name on the iPhone

Question

How can I save an image (like using UIImageWriteToSavedPhotosAlbum() method) with a filename of my choice to the private/var folder?

Answer 1

You can use below code, without use of ALAssetsLibrary...

NSString *fileName;

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissViewControllerAnimated:YES completion:^{

if( [picker sourceType] == UIImagePickerControllerSourceTypeCamera )
            {
                UIImageWriteToSavedPhotosAlbum(image,nil, nil, nil);
                [self performSelector:@selector(GetImageName) withObject:nil afterDelay:0.5];
            }
            else
            {
                NSURL *refURL = [info valueForKey:UIImagePickerControllerReferenceURL];
                PHFetchResult *result = [PHAsset fetchAssetsWithALAssetURLs:@[refURL] options:nil];
                fileName = [[result firstObject] filename];
            }
}];

-(void)GetImageName
{
 NSString *str =@"";
 PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
 fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:YES]];
 PHFetchResult *fetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];

if (fetchResult != nil && fetchResult.count > 0) {

    str = [[fetchResult lastObject] filename];
}

fileName = str;
}
