UIImagePickerController选择多个图像

Question

如何从UIImagePickerController中选择多个图像？

Answer 1

我认为你不能通过API直接做到这一点。但是你可以简单地保持选择器打开并在回调中建立一个图像列表：

- (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];
}
