加载引导图时隐藏状态栏

1. 首先

在Info.plist里添加布尔类型的

属性	值
Status bar is initially hidden	YES
View controller-based status bar appearance	NO

2. 引导页添加

#pragma mark --- "立即体验"点击进入App
-(void)intoApp{
    AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
    delegate.window.rootViewController = self.nav;
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];
}

或:

__weak AppDelegate *weakSelf = self;
    self.introductionView.didSelectedEnter = ^() {        
        weakSelf.introductionView = nil;
        [application setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];
    };

3. 最后

回到AppDelegate.m中新旧版本判断的地方别忘了正常进入时也要让状态栏显示。
[application setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];
