How to add image from iPhone gallery to an array IOS - ios

Question

As I am very much new to iOS development, I am trying to add an uiimage from image gallery to an array. But when I try to use the array to add image to uiimageview it shows me an error
[UIImage stringByDeletingPathExtension]: unrecognized selector sent to
instance 0x7fefd3ea02f0.
choosen_Imgae = info[ UIImagePickerControllerOriginalImage];
//
// choosen_Imgae = [self resizeImage:choosen_Image];
NSLog(#"chosen image %#",choosen_Imgae);
[picker dismissViewControllerAnimated:YES completion:NULL];
NSData *dataImage = [[NSData alloc] init];
dataImage = UIImagePNGRepresentation(choosen_Imgae);
if (dataImage != nil) {
[image_Arr insertObject:choosen_Imgae atIndex:indexxpath.row];
NSLog(#"image array after adding object %#",image_Arr);
}

Brother simply you can add the image to array.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *choosen_Imgae=[info objectForKey:#"UIImagePickerControllerOriginalImage"];
[image_Arr addObject:image];
[picker dismissViewControllerAnimated:YES completion:nil];
}
If you use NSData in didFinishPickingMediaWithInfo,it is long process(image->NSData).When fetching image from array again you have to convert NSData into image.So you can directly save the image into array.
Also you don't need to use insertObject to array.
When fetch the image from array
for (int i=0; i<[image_Arr count]; i++)
{
UIImage *fetch_Image = [image_Arr objectATIndex:i];
imageView.image = fetch_Image;
}
