Hide ActionSheet iOS - ios

Question

My application is about clicking on a button with background image named "uploadphoto1.png". When I click on the button, it shows me an ActionSheet letting me choose to take a picture with the camera or taking a picture from the library.
When, for example, I choose a picture from the camera, it lets me select a picture and show the picture in an imageView and it change the background image of the button from upload.png to save.png.
The problem now that when I click on the button with background Image "save1.png" it shows me the actionSheet.
I want to hide the actionSheet.
Here is the code:
- (void)viewDidLoad
{
[super viewDidLoad];
UIImage *buttonpicture =[UIImage imageNamed:#"uploadphoto1.png"];
[ButtonPicture setBackgroundImage:buttonpicture forState:UIControlStateNormal];
[ButtonPicture setFrame:CGRectMake(173, 269, 140, 30)];
}
- (IBAction)ButtonPicture:(UIButton *)sender
{
NSLog(#"Button Picture Pressed");
UIActionSheet *actionSheet = [[UIActionSheet alloc]initWithTitle:#"Photo" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"Picture From Camera",#"Picture From Gallery",nil];
[actionSheet setTag:1001];
[actionSheet showInView:self.view];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch (buttonIndex)
{
case 0:
{
// Take a picture from camera
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
}
break;
case 1:
{
// take a picture from gallery photos
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self.view addSubview:toolbar];
[self presentModalViewController:picker animated:YES];
}
break;
default:
break; }
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[ButtonPicture setBackgroundImage:[UIImage imageNamed:#"save1.png"] forState:UIControlStateNormal];
[picker dismissModalViewControllerAnimated:YES];
imageview.image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
//[actionSheet showInView:Nil];
}

#interface YourViewController
{
BOOL imageChanged;
}
- (void)viewDidLoad
{
[super viewDidLoad];
imageChanged = NO;
UIImage *buttonpicture =[UIImage imageNamed:#"uploadphoto1.png"];
[ButtonPicture setBackgroundImage:buttonpicture forState:UIControlStateNormal];
[ButtonPicture setFrame:CGRectMake(173, 269, 140, 30)];
}
- (IBAction)ButtonPicture:(UIButton *)sender
{
NSLog(#"Button Picture Pressed");
UIActionSheet *actionSheet = [[UIActionSheet alloc]initWithTitle:#"Photo" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"Picture From Camera",#"Picture From Gallery",nil];
[actionSheet setTag:1001];
if (!imageChanged)
[actionSheet showInView:self.view];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch (buttonIndex)
{
case 0:
// Take a picture from camera
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
break;
case 1:
// take a picture from gallery photos
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self.view addSubview:toolbar];
[self presentModalViewController:picker animated:YES];
break;
default:
break;
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[ButtonPicture setBackgroundImage:[UIImage imageNamed:#"save1.png"] forState:UIControlStateNormal];
imageChanged = YES;
[picker dismissModalViewControllerAnimated:YES];
imageview.image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
}

There are various ways this could be handled. One way is to set a boolean flag when you don't want tapping on the button to bring up the actionSheet. Then, in - (IBAction)ButtonPicture:(UIButton *)sender you can check the boolean flag to decide whether or not to create the actionSheet and show it.
