显示诸如“相机胶卷”之类的选项的视图的名称是什么？

Question

我想创建一个按钮，显示诸如“相机胶卷”的“发送”选项之类的选项，但是我不知道添加按钮是哪种视图，有人可以帮我吗？

Answer 1

I think you are looking for an UIBarButtonItem created with UIBarButtonSystemItemAction .

UIBarButtonItem * baritem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction systemItem target: some_view action:@selector(some_method:)];
