Question

I’m new to iphone. In my small application, how to get image path from photo library. I use this following code to getting images and placed in imageview.

-(IBAction) selectimage
{
UIImagePickerController *picker=[[UIImagePickerController alloc] init];
picker.delegate=self;
picker.sourceType=UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentModalViewController:picker animated:YES];
[picker release];
}
-(void) imagePickerController:(UIImagePickerController *)UIPicker didFinishPickingMediaWithInfo:(NSDictionary *) info
{
[UIPicker dismissModalViewControllerAnimated:YES];
imageview.image=[info objectForKey:"UIImagePickerControllerOriginalImage"];
    NSLog("Image Path=%@",imageview.image);
}

Its succefully placed to Imageview. But i cant get its imagepath. I’m using nslog(“%@”,imageview.image); it shows “Image Path=” in console.
How can i get its path and how to retrieve photos from photo library. Any body help me. Thanks in advance.

UIImagePickerControllerOriginalImage returns only the image’s data, with no reference to its local storage. I haven’t used it myself but I guess what you are looking for is

NSURL* localUrl = (NSURL *)[info valueForKey:UIImagePickerControllerReferenceURL];

At least, it’s the only way I know of to retrieve any URL.

To retrieve the image, have a look at this question. But also keep in mind, that you already have the image retrieved with

UIImage* image=(UIImage*)[info objectForKey:@"UIImagePickerControllerOriginalImage"];

so ask yourself if you really need this.
