Question

我正在使用UIImagePickerController从设备获取图像。我已经实施了以下步骤：

1. 获得许可： 隐私 - 照片库使用说明 - info.plist

2. 创建并呈现 UIImagePickerController 的实例。委托分配给自己。相机或库选项随UIAlertController一起提供。

   -(void) openGallery {
   UIImagePickerController *picker = [[UIImagePickerController alloc] init];
   picker.delegate = self;
   picker.allowsEditing = YES;
   UIAlertController *actionSheet = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];
   [actionSheet addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
   }]];
   [actionSheet addAction:[UIAlertAction actionWithTitle:@"Camera" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
   // take photo button tapped.
   picker.sourceType = UIImagePickerControllerSourceTypeCamera;
   [self presentViewController:picker animated:YES completion:NULL];
   }]];
   [actionSheet addAction:[UIAlertAction actionWithTitle:@"Photo Library" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
   // PhotoLibrary
   picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
   [self presentViewController:picker animated:YES completion:NULL];
   }]];
   [self presentViewController:actionSheet animated:YES completion:nil];
   }
   

3. 在委托上，图像已经到达，但是当我尝试将其转换为base64后将其上传到服务器时，AFNetworking抛出了错误：

   错误域=插件套件代码=13 "查询已取消" 用户信息={NSLocalizedDescription=查询已取消} 与目标C Xcode 9.3 iOS 11

   #pragma mark- UIImagePicker Delegate
   - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
   UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
   [picker dismissViewControllerAnimated:YES completion:NULL];
   [self.view setUserInteractionEnabled:NO];
   [self uploadThemeServiceCall: chosenImage];
   }
   

我尝试创建OS_ACTIVITY_MODE以在环境变量中禁用，但它不起作用。我尝试了其他可用的解决方案，但仍然不起作用。它工作正常，但现在不是了。

答：( 确保对象选择图像不是零。 B：( 使用NSData *imageData = UIImageJPEGRepresentation(imageObject , 1)将chosenImage转换为NSData。使用此图像数据作为您的NSUrlRequest正文。

Alse 在此处显示函数uploadThemeServiceCall的代码。
