在图库中上传图像时如何将图像路径作为参数发送

Question

在哪里保存图片路径我正在为图库上传图片，需要将图片路径作为参数传递

- (IBAction)chooseFileBtn:(id)sender {
    // For picking image from gallery

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentViewController:picker animated:YES completion:nil];
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    // output image

    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    //self.profileImageView.image = chosenImage;
    [picker dismissViewControllerAnimated:YES completion:nil];
}

在使用Image Picker时使用以下代码获取从库中选择的图片的路径ViewController:

 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissModalViewControllerAnimated:YES];
    NSURL *imagePath = [info objectForKey:@"UIImagePickerControllerReferenceURL"];
    NSString *imageName = [imagePath lastPathComponent];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:imageName];
    NSLog(@"localFilePath.%@",localFilePath);
  }

要将此路径作为参数上传到服务器，您可以创建一个 multipart/form-data 请求，如 (POST multipart/form-data with Objective-C) 我希望它能解决您的 issue.Happy 编码问题！
