Question

我有2个ImageView。我想将图像从库加载到ImageView。我的要求是，如果我第一次选择图像，则应将图像加载到ImageView 1中，当我第二次选择图像时，应将图像加载到ImageView 2中。

 -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo :(NSDictionary *)info
        {
          int  count=0;

            iscamera=YES;
            _imageuser.image=[info objectForKey:UIImagePickerControllerOriginalImage];
            _imageuser1.image=[info objectForKey:UIImagePickerControllerOriginalImage];
            _imageuser2.image=[info objectForKey:UIImagePickerControllerOriginalImage];

            if (ipc.sourceType == UIImagePickerControllerSourceTypeSavedPhotosAlbum) {
                if (count==0) {
                    pngData = UIImagePNGRepresentation(_imageuser.image);
                    pngData = UIImagePNGRepresentation(_imageuser1.image);
                }

        else if (count== 1)
        {
            pngData = UIImagePNGRepresentation(_imageuser.image);
            pngData = UIImagePNGRepresentation(_imageuser2.image);
        }
                count ++;
            }

            else{
                pngData = UIImagePNGRepresentation([self rotateUIImage:_imageuser.image clockwise:YES]);

            }
            [picker dismissViewControllerAnimated:YES completion:nil];

        }

Answer 1

    //initialize count with 0
let count = 0
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    imagePicker.dismiss(animated: true, completion: nil)
    // get image
  let capturedImage = info[UIImagePickerControllerOriginalImage] as? UIImage
    // you can set image to any imageview according to count value
   if(count == 0){
        firstImageView.image = capturedImage

    }else if (count == 1){

        secondImageView.image = capturedImage
    }else{


    }
    // increment count so that we can set image to appropriate image view
    count ++
}

Answer 2

您可以在image1中检查图像的NSdata。如果存在，则将第二个所选图像提供给第二个imageView，否则将其提供给第一个imageView。

ImageView图像从库中加载逻辑
