问题描述

使用故事板这很容易.您只需将操作拖到退出"即可.但是我应该如何从我的代码中调用它?

Using storyboard this is very easy. You just drag the action to "Exit". But how should I call it from my code?

推荐答案

1. 创建手动转场(ctrl-从文件所有者拖动到退出)，
2. 在绿色退出按钮下方的左侧控制器菜单中选择它.

1. Create a manual segue (ctrl-drag from File’s Owner to Exit),
2. Choose it in the Left Controller Menu below green EXIT button.

插入要放松的 Segue 名称.

Insert Name of Segue to unwind.

然后，- (void)performSegueWithIdentifier:(NSString *)identifier sender:(id)sender. 使用您的 segue 标识.

Then,- (void)performSegueWithIdentifier:(NSString *)identifier sender:(id)sender. with your segue identify.
