Building an iOS Camera App

Camera is a device which is used to take the images. In iOS UIImage PickerController class permits programmers to show the familiar Camera interface to their users and ask them to take a photo or shoot a video. The photos taken or the videos shot by the user with the UIImagePickerController class then become accessible to the programmer.

#import <UIKit/UIKit.h>
@interface ViewController : UIViewController<UIImagePickerControllerDelegate>
{
UIImagePickerController *imagePicker;
IBOutlet UIImageView * viewImage;
}
- (IBAction)showCamera:(id)sender;
@end

#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController

{
[super viewDidLoad];
}

{
[super didReceiveMemoryWarning];

UIImagePickerControllerSourceTypeCamera])
{
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
}

imagePicker.sourceType =
UIImagePickerControllerSourceTypePhotoLibrary;
}
[self presentModalViewController:imagePicker animated:YES];
}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info{
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
if (image == nil) {
