ImagePicker captures photo, but can't save to Album - ios

Question

I already wrote this code to make a profile photo for my app and it doesn't work. Been searching for different sources and couldn't find any.Please help. I can take a photo but it doesn't get saved on the Album and a photo can't be uploaded or saved on the UIImageView for the profile.
#import "ViewController.h"
#interface ViewController ()
{
UIImage *originalImage;
}
#property(nonatomic, weak) IBOutlet UIImageView *selectedImageView;
#property(nonatomic, weak) IBOutlet UIBarButtonItem *saveButton;
#end
#implementation ViewController
#synthesize selectedImageView, saveButton;
- (IBAction)photoFromAlbum
{
UIImagePickerController *photoPicker = [[UIImagePickerController alloc] init];
photoPicker.delegate = self;
photoPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:photoPicker animated:YES completion:NULL];
}
- (IBAction)photoFromCamera
{
UIImagePickerController *photoPicker = [[UIImagePickerController alloc] init];
photoPicker.delegate = self;
photoPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:photoPicker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)photoPicker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
self.saveButton.enabled = YES;
originalImage = [info valueForKey:UIImagePickerControllerOriginalImage];
[self.selectedImageView setImage:originalImage];
// [photoPicker dismissModalViewControllerAnimated:YES];
}
- (IBAction)saveImageToAlbum
{
UIImageWriteToSavedPhotosAlbum(self.selectedImageView.image, self, #selector(image:didFinishSavingWithError:contextInfo:), nil);
}
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo
{
NSString *alertTitle;
NSString *alertMessage;
if(!error)
{
alertTitle = #"Image Saved";
alertMessage = #"Image saved to photo album successfully.";
}
else
{
alertTitle = #"Error";
alertMessage = #"Unable to save to photo album.";
}
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:alertTitle
message:alertMessage
delegate:self
cancelButtonTitle:#"Okay"
otherButtonTitles:nil];
[alert show];
}
- (UIImage*)loadImage
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString* path = [documentsDirectory stringByAppendingPathComponent:
[NSString stringWithString: #"test.png"] ];
UIImage* image = [UIImage imageWithContentsOfFile:path];
return image;
