【问题描述】:
我正在使用UIImagePickerController 从设备获取图像。我已经实施了以下步骤:
- 获得许可: 隐私 - 照片库使用说明 - info.plist
-
创建并呈现 UIImagePickerController 的实例。代表被分配给自己。相机或库选项由 UIAlertController 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]; } -
在委托上,图像已到达,但是当我将其转换为 base64 后尝试将其上传到服务器时,AFNetworking 抛出错误:
错误域=PlugInKit 代码=13 "查询已取消" UserInfo={NSLocalizedDescription=查询已取消} 使用 Objective 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,但仍然无法正常工作。它工作正常,但现在不行了。
