我认为你不能通过 API 直接做到这一点。但是您可以简单地保持选择器打开并在回调中构建图像列表：

- (void) imagePickerController: (UIImagePickerController*) picker
    didFinishPickingMediaWithInfo: (NSDictionary*) info
{
    [images addObject:[info objectForKey:UIImagePickerControllerOriginalImage]];
    // There has to be some exit condition,
    // otherwise the user would pick forever.
    if ([images count] == 3)
        [self dismissModalViewControllerAnimated:YES];
}

I don’t think you can do that directly, through the API. But you can simply keep the picker open and build up a list of images in the callback:

- (void) imagePickerController: (UIImagePickerController*) picker
    didFinishPickingMediaWithInfo: (NSDictionary*) info
{
    [images addObject:[info objectForKey:UIImagePickerControllerOriginalImage]];
    // There has to be some exit condition,
    // otherwise the user would pick forever.
    if ([images count] == 3)
        [self dismissModalViewControllerAnimated:YES];
}
