Add Images To iPhone Simulator photo gallery

There are 2 ways to add image to iphone photo gallery:
  • Direct Method(drag and drop method).
  • Though coding.
Direct Method(drag and drop method):

Launch the simulator and go to this screen:

Drag the image which you want to add in gallery and drop on safari icon:


Click on image(anywhere inside the red rectangle in above image) and hold it:



You will get above 3 options: Save Image, Copy and Cancle.
Click on Save Image.
Now to see the saved image Go To below screen and click on photo:



 It will open the iPhone Album, select the 1st row of table, it will open all saved images.

Just double click on image to open.


Though coding : 
  1. Create a new project in xcode and name it as addImageInPhotoGallery.
  2. Add the image(Ref step 3 of .....) which you want to add in photo gallery in Resource folder of project.
  3. Open addImageInPhotoGallery.m, and write this code :

 - (void)viewDidLoad {
    
//suppose you have added photo.png in resource folder.
UIImage *sampleImage = [UIImage imageNamed:@"photo.png"];
    
UIImageWriteToSavedPhotosAlbum(sampleImage, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
   
 [super viewDidLoad];
}

- (void) image:(UIImage *) image didFinishSavingWithError:(NSError *) error contextInfo:(void *) contextInfo {
    UIAlertView *alert;
   
    // Unable to save the image 
    if (error)
        alert = [[UIAlertView alloc] initWithTitle:@"Error"
                                           message:@"Unable to save image to Photo Album."
                                          delegate:self cancelButtonTitle:@"Ok"
                                 otherButtonTitles:nil];
    else // All is well
        alert = [[UIAlertView alloc] initWithTitle:@"Success"
                                           message:@"Image saved to Photo Album."
                                          delegate:self cancelButtonTitle:@"Ok"
                                 otherButtonTitles:nil];
   
   
    [alert show];
    [alert release];
   
}
