Getting an image from the iPhone camera roll - iphone

Question

I currently have a UIImageView and a UIImage. How do I allow the user to select one of their photos from the camera roll?
There are possible duplicates, but I've had no luck. This might possibly be because I don't hook things up in the Interface Builder.
I would like something simple like UIImage * image = [UIImage imageFromCameraRoll], but unfortunately, that's not possible (I don't think so, at least).

Answer 1

Try this code
It is help to you get image from cameraroll & photolibrary. using UIImagePickerViewController
if you take Picture
From camera (in both open As UINavigationcontroller).
From Gallery(for ipad open as UIpopovercontroller & for iphone open as nvigationcontroller).
First set delegate
#interface camera : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate,UIPopoverControllerDelegate>
get image from Camera
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *imagePicker =
[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType =
UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
nil];
imagePicker.allowsEditing = YES;
imagePicker.wantsFullScreenLayout = YES;
[self presentViewController:imagePicker animated:YES completion:nil];
newMedia = YES;
iscamera = 0;
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error to access Camera"
message:#""
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
Get image from Gallery
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
UIImagePickerController *_picker=nil;
if (popoverController) {
[popoverController dismissPopoverAnimated:NO];
}
_picker = [[UIImagePickerController alloc] init];
_picker.delegate = self;
_picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
_picker.wantsFullScreenLayout = YES;
//[popoverController presentPopoverFromBarButtonItem:sender
// permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
[self presentViewController:_picker animated:YES completion:nil];
} else
{
popoverController = [[UIPopoverController alloc] initWithContentViewController:_picker];
[popoverController setDelegate:self];
[popoverController presentPopoverFromRect:btn.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionLeft
animated:YES];
}
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error access photo library"
message:#"your device non support photo library"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
Both Result you get in Delegate Method
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// write your code here ........
}

Use UIImagePickerController, see the Apple docs.
Select the source type:
#property (nonatomic) UIImagePickerControllerSourceType sourceType
From on on these:
UIImagePickerControllerSourceTypePhotoLibrary,
UIImagePickerControllerSourceTypeCamera,
UIImagePickerControllerSourceTypeSavedPhotosAlbum
