iPhone,如何强制一个视图进入横向模式？

Question

如何将一个视图强制为图形的横向模式.

我想单击一个标签栏按钮以显示图形视图,然后当在该视图上单击一个按钮时,我想以纵向模式推送我需要的子屏幕.

一旦他们点击回来我想回到横向的图表视图.

使用UIView的transform属性按PI弧度旋转它:

-(void)viewWillAppear:(BOOL)animated
{
CGAffineTransform newTransform = CGAffineTransformMake(0.0,1.0,-1.0,0.0,0.0,0.0);         
self.view.transform = newTransform;

}
