如何设置启动页面的动画?

---

/启动页只能有assets的图片或者storyboard图片的形式,所以无法直接做动画效果,但是可以通过获取storyboard的Vc.view 实现动画,如下

1.在LaunchStoryboard中添加启动页图片并设置约束

---

2.在控制器中的加载view时进行如下操作:

2.1获取到LaunchstoryBoard中view

     UIStoryboard*styB = [UIStoryboard storyboardWithName:@"LaunchScreen" bundle:nil];

    UIViewController*VC = [styB instantiateInitialViewController];//找到登陆界面初始化的控制器

    UIView*Boardview = VC.view;

2.2  将获取到的view和控制器的view建立联系

  [self.view addSubview:Boardview];

2.3 给view设置动画效果

    [UIView animateWithDuration:1.0 animations:^{

        Boardview.transform = CGAffineTransformMakeScale(1.5, 1.5);

        Boardview.alpha=0;

2.4 移除view

}completion:^(BOOLfinished){

    [BoardviewremoveFromSuperview];

 }];

}
