我的 objective-c 代码出错，出现 Code=13 错误，并且不在 ImageView 中显示相机照片或图书馆的图像。

我正在使用 Xcode 10.1，部署目标为 12.0，并且我将使用 UIImagePickerController not picking image in iOS 9 中的示例

我有两个问题:

1) 即使我在 p-list 中添加了“隐私 - 照片库使用说明 | 我们想使用该库”，它仍然给我这个错误:

[发现] 发现扩展时遇到的错误:Error Domain=PlugInKit Code=13 "query cancelled"UserInfo={NSLocalizedDescription=query cancelled}

我做错了什么？

2) 我无法在 LoveImage View 中显示图像。我在这里做错了什么？

下面是.m文件:

-(IBAction)imagepickertapped:(id)sender { 
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Attach image" message:@"" preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction* pickFromGallery = [UIAlertAction actionWithTitle:@"Take a photo"
                                                          style:UIAlertActionStyleDefault
                                                        handler:^(UIAlertAction * action) {
                                                            if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
                                                            {
                                                                UIImagePickerController* picker = [[UIImagePickerController alloc] init];
                                                                picker.sourceType = UIImagePickerControllerSourceTypeCamera;
                                                                picker.delegate = self;
                                                                [self presentViewController:picker animated:YES completion:NULL];
                                                            }

                                                        }];
UIAlertAction* takeAPicture = [UIAlertAction actionWithTitle:@"Choose from gallery"
style:UIAlertActionStyleDefault
                                                     handler:^(UIAlertAction * action) {
                                                         UIImagePickerController* picker = [[UIImagePickerController alloc] init];
                                                         picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
                                                         picker.delegate = self;
                                                         [self presentViewController:picker animated:YES completion:NULL];
                                                     }];
UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel"
                                         style:UIAlertActionStyleCancel
                                               handler:^(UIAlertAction * action) {
                                               }];

[alertController addAction:pickFromGallery];
[alertController addAction:takeAPicture];
[alertController addAction:cancel];
[self presentViewController:alertController animated:YES completion:nil]; }

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info {
UIImage *LoveImage = info[UIImagePickerControllerOriginalImage];
[picker dismissViewControllerAnimated:YES completion:nil];
self.LoveImage = info[UIImagePickerControllerOriginalImage];}

-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:nil];}

最佳答案

将您的 didfinish 方法代码更改为以下。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info {
    UIImage *LoveImage = info[UIImagePickerControllerOriginalImage];
    [picker dismissViewControllerAnimated:YES completion:nil];
    self.LoveImage.image = LoveImage;
}

LoveImage 是一个 ImageView 。我们不能直接给它分配图像。它有一个 image 属性，所以我们必须设置它的 image 属性。
