这段代码在本机版本中不起作用。我还没有安装，但正如您所说，这不起作用，可能在ios中您无法防止。您是否尝试过FLAG_安全选项

- (void)applicationWillResignActive:(UIApplication *)application {

// fill screen with our own colour
UIView *colourView = [[UIView alloc]initWithFrame:self.window.frame];
colourView.backgroundColor = [UIColor whiteColor];
colourView.tag = 1234;
colourView.alpha = 0;
[self.window addSubview:colourView];
[self.window bringSubviewToFront:colourView];

// fade in the view
[UIView animateWithDuration:0.5 animations:^{
  colourView.alpha = 1;
}];
}

- (void)applicationDidBecomeActive:(UIApplication \*)application {
// grab a reference to our coloured view
UIView \*colourView = [self.window viewWithTag:1234];
// fade away colour view from main view
[UIView animateWithDuration:0.5 animations:^{
colourView.alpha = 0;
} completion:^(BOOL finished) {
// remove when finished fading
[colourView removeFromSuperview];
}];
}
