窗口关闭时停止模态（Cocoa） [英] Stopping modal when window is closed (Cocoa)

问题描述

我目前正在使用此代码显示模态窗口：

I am currently displaying a modal window by using this code:

[[NSApplication sharedApplication] runModalForWindow:mainWindow];

但是，当我关闭此窗口时，其他窗口仍然处于非活动状态。当窗口使用red x关闭时，如何运行 stopModal 方法？

However, when I close this window, the other windows are still inactive. How do I run the stopModal method when the window is closed using the "red x"?

推荐答案

您可以为窗口创建委托让它响应

- （void）windowWillClose：（NSNotification *）通知或

- （void）windowShouldClose： NSNotification *）notification 方法：

You can create a delegate for the window and have it respond to either the
-(void)windowWillClose:(NSNotification *)notification or the
- (void)windowShouldClose:(NSNotification *)notification methods like so:

- (void)windowWillClose:(NSNotification *)notification {
   [[NSApplication sharedApplication] stopModal];
}
