Question

使用xib而不是代码进行测试，就像魅力一样。仍然认为应找到适当的解决方案和原因。将继续根据需要进行更新

使用NSProgressIndicator创建一个popUp窗口，以显示通信过程的进展情况。

问题是progressIndicator不会更新。

检查并正常工作：

alertPopUp是关键
alertPopUp是最前列的
alertPopUp接收增量调用
progressIndicator值正确更新
progressIndicator，主窗口progressIndicator bar填充

已检查且无法正常工作：

progressIndicator栏不会填写

注意到行为：

在3个手指上向上滑动，显示系统中所有可用的窗口，alertPopUp窗口将更新一次，且只会更新一次。

在主应用程序窗口中测试了相同的代码并且运行良好。

如果我将alertPopUp窗口设为主，则不会有所作为。

我们非常欢迎您的想法，完全被阻止。

将向您显示alertPopUp代码和来电者：

您可以使用它来调用测试：

    [self alertPopUpSaveProgress:@(100)];
    [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(increments:) userInfo:@(0) repeats:NO];
}

- (void)increments:(NSTimer *)timer{

    NSNumber *inc = @([[timer userInfo] integerValue] + 1);
    if([inc integerValue] > 99)
        return;
    NSLog(@"patch iskey >> %d || patch is main >> %d", [self.view.window isKeyWindow], [self.view.window isMainWindow]);
    [alertProgress incrementProgress];
    [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(increments:) userInfo:inc repeats:NO];
}

- (void)alertPopUpSaveProgress:(NSNumber *)numberOfSteps{
    alertProgress = [XTAlertPopUp alertProgressCalledFromView:self.view
                                                        withMessage:@"Saving changes"
                                             numberOfProgressStages:[numberOfSteps unsignedIntegerValue]
                                               andCancelButtonTitle:@"cancel"
                                                    settingDelegate:self];
    [alertProgress shootThreadedAlert];
}

NSWindow不令人耳目一新
