如何使用Three20弹出模态视图？

Question

我有一个模态视图控制器名称:ComposeMessageViewController.和主视图控制器名称:MainViewController.在MainViewController中,我将URL映射到ComposeMessageViewController,如下所示:

[map from:@"up://home/messages/compose_message/" toModalViewController:[ComposeMessageViewController class]];

在MainViewController中,我调用此模态视图:

TTURLAction *urlAction  =   [[TTURLAction actionWithURLPath:@"up://home/messages/compose_message/"] applyAnimated:YES];
[[TTNavigator navigator]    openURLAction:urlAction];

但是当我完成它时,我不知道如何删除(解散)ComposeMessageViewController.有人可以帮帮我吗？

创建一个将委托设置为self且选择器设置为的按钮dismissModalViewController.
