using this delegate how to get image file path and display this image another view

Answer 1

In the image file path you will get the url of asset, and you can use that asset url to display the image on image view.

First import

#import <AssetsLibrary/AssetsLibrary.h>

in you project, then in the delegate method of UIImagePicker

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 
  // You will get the image url like this
  NSURL *imageURL = [info valueForKey:UIImagePickerControllerReferenceURL];
}

Now to display the image, use this code

ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset) {
        ALAssetRepresentation *rep = [myasset defaultRepresentation];
        CGImageRef iref = [rep fullResolutionImage];
        if (iref) {
            //here you get the image
            largeimage = [UIImage imageWithCGImage:iref];
        }
    };

ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc] init];
[assetslibrary assetForURL:imageURL 
                   resultBlock:resultblock
                  failureBlock:nil];

If you directly want to access the image then use this

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