当我使用view的bounds属性时，iPad的方向无法正常工作

Question

当我将iPad方向属性设置为横向时，我的iPad应用程序处于纵向状态，其视图边界不会改变，只需768 x 1024尺寸。

这里我的问题是当我改变方向时视图的界限不会改变。

这是我的代码：

if(self.hidden || hiding || !view.superview) {
    UIWindow *viewWindow=[[UIWindow alloc]init]; 

    if([self isPad]){
        viewWindow = forView.window;
    }

    [[NSNotificationCenter defaultCenter] postNotificationName:CustomKeyboardWillShowNotification object:self];

// remove from old view and add to new view (if necessary)
if(view.superview && (view.superview != viewWindow)) {
    [view removeFromSuperview];
}
if(!view.superview) {

         CGFloat x;
         if([self isPad]){
            [view setFrame:CGRectMake(0, 0, 1024, 198)];
            NSLog(@"view frame=%@",view);
            x = view.bounds.size.width /2;

            NSLog(@"x=%f",x);

        }else
        {
             x = view.bounds.size.width / 2;
        }

        //CGFloat y = viewWindow.frame.size.height + (view.frame.size.height / 2);
        CGFloat y;
        if([self isPad]){

             y = viewWindow.frame.size.height/1.3 + (view.frame.size.height);
             NSLog(@"y=%f",y);

        }else{
            y = viewWindow.frame.size.height + (view.frame.size.height / 2);
        }
   //self.hiddenCenter = CGPointMake(x, y);
   self.hiddenCenter = CGPointMake(x, y);
   view.center = hiddenCenter;
