Objective c ruby motion在UISplitViewController上隐藏圆角

我已经找到了Objective-c，我需要这样做，但是您如何用ruby重新编写它

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{  
    [self performSelector:@selector(fixRoundedSplitViewCorner) withObject:NULL afterDelay:0];
}

-(void) fixRoundedSplitViewCorner {  
    [self explode:[[UIApplication sharedApplication] keyWindow] level:0];  
}

-(void) explode:(id)aView level:(int)level 
{   
    if ([aView isKindOfClass:[UIImageView class]]) {
        UIImageView* roundedCornerImage = (UIImageView*)aView;
        roundedCornerImage.hidden = YES;
    }
    if (level < 2) 
    {
        for (UIView *subview in [aView subviews]) {
            [self explode:subview level:(level + 1)];
        }
    }
}

-（void）从InterfaceOrientation（接口方向）中删除了RotateFromInterfaceOrientation：（UIInterfaceOrientation）
{  
[self-performSelector:@selector（fixRoundedSplitViewCorner）with object:NULL afterDelay:0]；
}
-（void）fixRoundedSplitViewCorner{
[自分解：[[UIApplication sharedApplication]keyWindow]级别：0]；
}
-（无效）分解：（id）视图级别：（int）级别
{   
if（[aView iskindof类：[UIImageView类]]）{
UIImageView*roundedCornerImage=（UIImageView*）视图；
roundedCornerImage.hidden=是；
}
如果（级别<2）
{
对于（UIView*子视图在[aView子视图]中）{
[自分解：子视图层级：（层级+1）]；
}
}
}

像这样的东西怎么样：

def didRotateFromInterfaceOrientation(fromInterfaceOrientation)
# you can just skip calling performSelector and call the method directly
#   self.performSelector('fixRoundedSplitViewCorner', withObject:nil, afterDelay:0)
    self.fixRoundedSplitViewCorner()
end

def fixRoundedSplitViewCorner
    self.explode(UIApplication.sharedApplication.keyWindow, level:0)
end

def explode(aView, level:level)
    if aView.class == UIImageView
        aView.hidden = true
    end
    if level < 2
        for subview in aView.subviews
            self.explode(subview, level:(level + 1))
        end
    end
end

def didRotateFromInterfaceOrientation（来自InterfaceOrientation）
#您可以跳过调用PerformSelect，直接调用该方法
#self.performSelector（'fixRoundedSplitViewCorner'，对象：nil，后延迟：0）
self.fixRoundedSplitViewCorner（）
结束
def fixRoundedSplitViewCorner
self.explode（UIApplication.sharedApplication.keyWindow，级别：0）
结束
def爆炸（视图，级别：级别）
如果aView.class==UIImageView
aView.hidden=true
结束
如果级别<2
对于aView.subview中的子视图
自我分解（子视图，级别：（级别+1））
结束
结束
结束
