基于方向的UIView背景图像

Question

如何在ios6 for iphone和ipad中为不同方向设置不同的背景图像？现在我将图像bg设置为垂直，如下所示，

- (void)viewDidLoad
{
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"ihome.png"]];
[super viewDidLoad];
}

我厌倦了以下编码，甚至没有进入代码

 -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
if (toInterfaceOrientation==UIInterfaceOrientationMaskLandscapeRight)
{
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lhomescreen.png"]];
}
if (toInterfaceOrientation==UIInterfaceOrientationMaskLandscapeLeft)
{
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lhomescreen.png"]];
}
if (toInterfaceOrientation==UIInterfaceOrientationMaskPortrait)
{
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"ihome.png"]];
}

return YES;

}

请帮我解决一下

修改

- (BOOL)shouldAutorotate
{
return YES;
}

 - (NSUInteger)supportedInterfaceOrientations
  {
// return (UIInterfaceOrientationMaskAllButUpsideDown);
 return (UIInterfaceOrientationMaskAll);
 }

 - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{

if (toInterfaceOrientation==UIInterfaceOrientationMaskLandscapeRight)

          self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lhomescreen.png"]];

if (toInterfaceOrientation==UIInterfaceOrientationMaskLandscapeLeft)

         self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lhomescreen.png"]];

if (toInterfaceOrientation==UIInterfaceOrientationMaskPortrait)

       self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"ihome.png"]];


  // return YES;
 }

来自apple doc：

“shouldAutorotateToInterfaceOrientation: 返回一个布尔值，指示视图控制器是否支持指定的方向。 （在iOS 6.0中不推荐使用。改为覆盖supportedInterfaceOrientations和preferredInterfaceOrientationForPresentation方法。）“

- (BOOL)shouldAutorotate
{
if (toInterfaceOrientation==UIInterfaceOrientationMaskLandscapeRight)

      self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lhomescreen.png"]];

if (toInterfaceOrientation==UIInterfaceOrientationMaskLandscapeLeft)

     self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lhomescreen.png"]];

if (toInterfaceOrientation==UIInterfaceOrientationMaskPortrait)

   self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"ihome.png"]];


return YES;
}
