Use Camera & Photo Album - ios

Question

I am trying to have a button that is meant to open the camera and a button that is meant to open camera roll. Here is my code:
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (IBAction)getCameraPicture:(id)sender{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.allowsEditing = NO;
picker.sourceType = (sender == takePictureButton) ?
UIImagePickerControllerSourceTypeCamera : UIImagePickerControllerSourceTypeSavedPhotosAlbum;
}
- (IBAction)selectExistingPicture {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.allowsEditing = NO;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}else{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Sorry" message:#"Device does not support photo library" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:nil];
[alert show];
}
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo {
imageView.image = image;
}
- (void)viewDidLoad
{
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
takePictureButton.hidden = YES;
}
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
Any ideas on why it's not working? Everything is linked but the buttons do nothing
Thanks
EDIT
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController <UIImagePickerControllerDelegate> {
IBOutlet UIButton *takePictureButton;
IBOutlet UIImageView *imageView;
}
#property (nonatomic, retain) IBOutlet UIImageView *imageView;
#property (nonatomic, retain) IBOutlet UIButton *takePictureButton;
- (IBAction)getCameraPicture:(id)sender;
- (IBAction)selectExistingPicture;
#end

Just add :
[self presentViewController:picker animated:YES completion:nil];
at the end of your 'getCameraPicture:' and in your 'selectExistingPicture:'.
And you also might want to add the 'UIImagePickerControllerDelegate' to your view controller's interface so the 'didFinishPickingImage' gets called.
Edit :
You should replace your :
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo;
with
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
beccause that method is long deprecated.
Use it like this :
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.imageView.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
