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];
}
