自定义UIActivityViewController类似于上下滑动的视图

Question

有没有办法子类化或自定义UIActivityViewController来创建一种自定义视图？例如，请参阅应用Overcast下面的图片。我想创建一个类似的视图，如果你点击一个按钮，视图会弹出，当你点击视图外，它会向下滑动。

为什么不使用UIView？将它的初始帧的y值设置为-self.customView.frame.size.height，并使用[UIView animateWithDuration]将其框架设置为正常位置

-(void)showCustomView{
    [self.customview setFrame:CGRectMake(0, -self.customView.frame.size.height, self.view.bounds.size.height+self.customView.frame.size.width, self.customView.frame.size.height)];
    [UIView animateWithDuration:0.25 animations:^{
        [self.customView setFrame:CGRectMake(0, -self.view.frame.size.height,  self.view.bounds.size.height-self.customView.frame.size.width, self.customView.frame.size.height)];

    }];
}

-(void)hideCustomView{
    [UIView animateWithDuration:0.25 animations:^{
        [self.customView setFrame:CGRectMake(0, -self.customView.frame.size.height,  self.customView.bounds.size.height+self.customView.frame.size.width, self.customView.frame.size.height)];

    }];
}

添加UITapGestureRecognizer并在hideCustomView

之外点按customView
