applicationWillTerminate 未调用

发布于 2024-12-17 03:12:23 字数 252 浏览 0 评论 0原文

我实现了 applicationWillTerminate 方法，但从未调用它

-(void)applicationWillTerminate:(NSNotification *)notification
{
    [[NSApplication sharedApplication] terminate:self];
    NSLog(@"EOP");
}

如何在应用程序关闭之前执行一些代码？

谢谢

原文

I implemented applicationWillTerminate method, but it's never called

-(void)applicationWillTerminate:(NSNotification *)notification
{
    [[NSApplication sharedApplication] terminate:self];
    NSLog(@"EOP");
}

How to execute some code before application close?

Thanks

我刚刚添加了

-(BOOL) applicationShouldTerminateAfterLastWindowClosed:(NSApplication *) sender{
return YES;
}

Now applicationWillTerminate 调用

I just added

-(BOOL) applicationShouldTerminateAfterLastWindowClosed:(NSApplication *) sender{
return YES;
}

Now applicationWillTerminate invokes

解决方案 1：

在项目信息（NSSupportsSuddenTermination 键）中将应用程序可以立即终止设置为NO。
然后，在应用程序退出之前，将调用 applicationWillTerminate 函数。

解决方案 2：

如果您需要能够取消终止，那么您应该重写 applicationShouldTerminate 函数

func applicationShouldTerminate(_ sender: NSApplication) -> NSApplication.TerminateReply {
    // Do some stuff before quitting for good
    return .terminateNow
}

Solution 1:

Set the Application can be killed immediately to NO in the project info ( NSSupportsSuddenTermination key ).
The applicationWillTerminate function will then be called before the application quits.

Solution 2:

If you need to be able to cancel the termination, then you should rather override the applicationShouldTerminate function

func applicationShouldTerminate(_ sender: NSApplication) -> NSApplication.TerminateReply {
    // Do some stuff before quitting for good
    return .terminateNow
}
