iphone - UIImagePickerController 选取多个图像

Question

如何从 UIImagePickerController 中选取多个图像？

Answer 1

我认为您不能通过 API 直接执行此操作。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];
}
