UIViewController调整大小后如何刷新视图？我需要一种类似于reloadDatain的方法UITableViewController。

是否有其他可能性来调整视图的大小UIViewController而不重新加载？

我的代码是：

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    orientation = toInterfaceOrientation;
    if(orientation==3 || orientation==4)
    {
        heightBoxDimension1 = [GlobalData sharedGlobalData].heightLandscape;
        widthBoxDimension1 = [GlobalData sharedGlobalData].widthLandscapeBig;
        widthBoxDimension2 = [GlobalData sharedGlobalData].widthLandscapeSmall;
    }
    else 
    {
        heightBoxDimension1 = [GlobalData sharedGlobalData].heightPortrait;
        widthBoxDimension1 = [GlobalData sharedGlobalData].widthPortraitBig;
        widthBoxDimension2 = [GlobalData sharedGlobalData].widthPortraitSmall;
    }
    for(UIView* view in self.view.subviews)
    {
        NSLog(@"%.0f %.0f %.0f %.0f ", view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height);
        if(view.frame.size.width >400)
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, widthBoxDimension1, heightBoxDimension1)];
            NSLog(@"%.0f %.0f %.0f %.0f ", view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height);
        }
        else
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, widthBoxDimension2, heightBoxDimension1)]; 
            NSLog(@"%.0f %.0f %.0f %.0f ", view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height);
        }
    }
    [self.view setNeedsDisplay];

}

我有一类全局变量，在其中放置视图的静态尺寸，我有两种视图，高度相同但宽度不同。当打开模拟器进入此方法但更改视图框架后，不要重新加载这些视图...

控制台的输出是：

2012-06-05 10:53:09.309 TemplateiPad2[12561:207] 8 8 752 318 
2012-06-05 10:53:09.309 TemplateiPad2[12561:207] 8 8 752 446 
2012-06-05 10:53:09.309 TemplateiPad2[12561:207] 8 334 372 318 
2012-06-05 10:53:09.309 TemplateiPad2[12561:207] 8 334 372 446

做好重新框架，但不要重新加载。
