How to load captured image from photo album - ios

Question

I have a button to capture picture then it save to photoAlbum. I used another button for load image from using imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; then i implemented didFinishPickingMediaWithInfo: for loading photo album to newImage. My need is after capture photo i have alertview then click YES button automatically load last captured image PhotoAlbum and add newImage. Is it possible?
- (void)saveImageToPhotoAlbum
{
[self.library saveImage:[self stillImage] toAlbum:#"Album" withCompletionBlock:^(NSError *error) {
if (error!=nil) {
NSLog(#"Big error: %#", [error description]);
}
}];
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:#"Gallery"
message:#"Do you want to use the captured image?" delegate:self
cancelButtonTitle:#"Cancel" otherButtonTitles:#"Yes", nil];
alertView.tag = 2;
[alertView show];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
//set image
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
newImage = [[UIImageView alloc] initWithImage:[info objectForKey:UIImagePickerControllerOriginalImage]];
[newImage setFrame:CGRectMake(0, 0, 320, 568)];
[self.view addSubView:newImage];
}
I need to display last captured image to newImage click of alertView button:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
// the user clicked one of the OK/Cancel buttons
if (buttonIndex == 1){
}
}

Before use below code take UIImage *img in .h file
- (void)saveImageToPhotoAlbum
{
[self.library saveImage:[self stillImage] toAlbum:#"Album" withCompletionBlock:^(NSError *error) {
if (error!=nil) {
NSLog(#"Big error: %#", [error description]);
}
}];
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:#"Gallery"
message:#"Do you want to use the captured image?" delegate:self
cancelButtonTitle:#"Cancel" otherButtonTitles:#"Yes", nil];
alertView.tag = 2;
[alertView show];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
//set image
img=nil;
img=[info objectForKey:UIImagePickerControllerOriginalImage];
[self saveImageToPhotoAlbum];
// [self dismissViewControllerAnimated:YES completion:nil];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 1)
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
if(newImage)
{
[newImage removeFromSuperview];
newImage=nil;
}
newImage = [[UIImageView alloc] initWithImage:img];
[newImage setFrame:CGRectMake(0, 0, 320, 568)];
[self.view addSubView:newImage];
}
[picker dismissViewControllerAnimated:YES completion:nil];
}
else
{
img=nil;
[picker dismissViewControllerAnimated:YES completion:nil];
}
}
