Question

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

1. 许可：隐私 - 照片库使用说明 - info.plist
2. 创建并呈现UIImagePickerController的实例。代表被分配给自己。 UIAlertController提供了Camera或Library选项。

   -(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，当我将其转换为base64后尝试将其上传到服务器时，AFNetworking抛出了错误： 错误域= PlugInKit代码= 13“查询已取消”UserInfo = {NSLocalizedDescription =查询已取消}，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。我尝试了其他解决方案，但仍然无法正常工作。它工作正常，但现在不是。

Answer 1

A :)确保对象selectedImage不是零。 B :)使用NSData *imageData = UIImageJPEGRepresentation(imageObject , 1)将chosenImage转换为NSData。使用此imageData作为你的NSUrlRequest身体。

Alse在这里显示函数uploadThemeServiceCall的代码。
