basically you would need to use a UIImagePicker and its delegate methods to do this. this video covers adding the code below

you need to conform to the UIImagePickerControllerDelegate and UINavigationControllerDelegate protocols in your .h

 @interface SomeViewController : UITableViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>

and also add a property for a imagePickerController and a property to hold the image that gets taken

@property (nonatomic, strong) UIImagePickerController *imagePicker;
@property (nonatomic, strong) UIImage *image;

then whenever you want the imagePicker to appear present the imagePicker

         self.imagePicker = [[UIImagePickerController alloc] init];
        self.imagePicker.delegate = self;
        self.imagePicker.allowsEditing = NO;

        //camera is available
        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {

            self.imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;

        } else {

            self.imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        }

        self.imagePicker.mediaTypes = [UIImagePickerController    availableMediaTypesForSourceType:self.imagePicker.sourceType];

        [self presentViewController:self.imagePicker animated:NO completion:nil];

then implement a few delegate methods:

#pragma mark - ImagePickerController Delegate

//handles cancelation
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {

    [self dismissViewControllerAnimated:NO completion:nil];

}

//this runs when you finish taking a picture
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

    if([mediaType isEqualToString:(NSString *)kUTTypeImage]) {

        //set the photo that was taken as your photo property
        self.image = [info objectForKey:UIImagePickerControllerOriginalImage];
        //set your imageViews image to the image property
        self.imageView.image = self.image

        if(self.imagePicker.sourceType == UIImagePickerControllerSourceTypeCamera) {

            //save the image to the photos album
            UIImageWriteToSavedPhotosAlbum(self.image, nil, nil, nil);
        }


    } 


    [self dismissViewControllerAnimated:YES completion:nil];
}
