设备旋转手动旋转视图

我使用此方法根据方向手动旋转一些视图和子视图：

CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(0);
landscapeTransform = CGAffineTransformTranslate( landscapeTransform, 0.0, 0.0 );
[self.navigationController.view setTransform:landscapeTransform];
CGRect theFrame = self.view.bounds;
self.navigationController.view.frame= CGRectMake(0, 0, 320, 480);

现在这适用于从横向旋转到纵向，但如果我尝试旋转到横向，则框架 CGRect 没有任何逻辑意义（它看起来像这样）（200，-50，宽度，高度）。我还必须硬设置纵向框架，如果我得到 self.view.frame 或边界或其他我检查的框架，它会在每次旋转时发生变化

。有没有更好的方法来设置更符合逻辑而不是硬编码的框架？

I am manually rotating a few views and subviews depending on orientation using this method:

CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(0);
landscapeTransform = CGAffineTransformTranslate( landscapeTransform, 0.0, 0.0 );
[self.navigationController.view setTransform:landscapeTransform];
CGRect theFrame = self.view.bounds;
self.navigationController.view.frame= CGRectMake(0, 0, 320, 480);

Now this works for rotating from landscape to portrait but if I try and rotate to landscape the frame CGRect doesn't make any logical sense (it looks like its something like (200,-50, width, height). I also have to hard set the frame for portrait, if I get the frame for self.view.frame or bounds or anything else I check, it changes each time I rotate.

Is there any better way to set the frame thats more logical and not hard coded?
