Add a button to the Camera Toolbar on the iPhone

Question

I am using a UIImagePickerController subclass to take photos in my app.

The toolbar for the camera has a cancel button and a photo button on it. I would also like to add another button on the right.

I have tried to add a UIBarButtonItem to the subclass's toolbar, but that doesn't work. I have also tried to make a UIToolbar that looks like the camera toolbar, so I can just overlay a toolbar with one button invisibly, but I can't seem to match the style of the camera toolbar.

Any ideas on how to add a button to the camera toolbar?

您不能像这样自定义UIImagePickerController工具栏，要做的是使用UIImagePickerController中的覆盖视图，它允许您指定用于选择器的视图，而不是默认视图，这是信息链接关于UIImagePickerController的这个overlayview属性
