这取决于您如何呈现imagepickercontroller如果您使用了PeserntModelViewController初始化:然后使用DismissModalViewController初始化:您必须在本地创建UIImagePickerController的实例,并且在alertview委托方法中,只需将其关闭。我更新了问题。一般来说,我知道如何取消它,因为我是因为取消而取消它,但我不知道在显示警报后如何取消它。您能更具体一些吗?如何在本地创建实例?创建UIImagePickerController*imagepicker;在controller.h和alertview delegte[self dismissModalViewControllerAnimated:TRUE]中;到这里来
