iphone - 如何将图像保存到服务器

Question

我是 iPhone 应用程序的新手。

我想要的是将图像保存在服务器上。我有的是按钮。单击时，它要求提供照片或库，然后我选择图像。

但我不知道如何在服务器上保存这个图像。

#pragma mark - UIActionSheetDelegate

- (void)actionSheet:(UIActionSheet *)theActionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    if (buttonIndex == 0) {
        [self takePhotoCam];
    } else if (buttonIndex == 1) {
        [self choosePhotoFromLibrary];
    }
}


- (IBAction)takePhotoAction:(id)sender {
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        UIActionSheet *actionSheet = [[UIActionSheet alloc]
                                      initWithTitle:nil
                                      delegate:self
                                      cancelButtonTitle:@"Cancel"
                                      destructiveButtonTitle:nil
                                      otherButtonTitles:@"Take Photo", @"Choose From Library", nil];

        [actionSheet showInView:self.view];
    } else {
        [self choosePhotoFromLibrary];
    }
}

- (void)takePhotoCam {
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePicker.delegate = self;
    imagePicker.allowsEditing = YES;
    [self.navigationController presentViewController:imagePicker animated:YES completion:nil];
}

- (void)choosePhotoFromLibrary {
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    imagePicker.delegate = self;
    imagePicker.allowsEditing = YES;
    [self.navigationController presentViewController:imagePicker animated:YES completion:nil];
}
