iOS屏幕强制横屏，如右转或左转

背景：整个工程只支持竖屏，webview某一页面需要横屏

代码实现:

#pragma mark 旋转屏幕

/*

 *函数名:rotateScreenToRight
返回值:void

 描述：屏幕强制右转

 开发者： 2015/7/27

 */
- (void)rotateScreenToRight {
   
BOOL isStatusBarHidden = [UIApplicationsharedApplication].statusBarHidden;

    [[UIApplicationsharedApplication]
setStatusBarHidden:!isStatusBarHiddenwithAnimation:UIStatusBarAnimationFade];

    //横屏强制转换

    CGRect frame = [UIScreenmainScreen].applicationFrame;
   
CGPoint center = CGPointMake(frame.origin.x +ceil(frame.size.width/2),
frame.origin.y +ceil(frame.size.height/2));

    [[UIApplicationsharedApplication]
setStatusBarOrientation:UIInterfaceOrientationLandscapeRightanimated:YES];

    

    CGFloat duration = [UIApplicationsharedApplication].statusBarOrientationAnimationDuration;

    [UIViewbeginAnimations:nilcontext:nil];

    [UIViewsetAnimationDuration:duration];
   
self.view.center = center;

    self.view.transform =CGAffineTransformRotate(self.view.transform,M_PI/2);
   
if (!isStatusBarHidden) {
       
m_webView.frame =
CGRectMake(0,
0, frame.size.height, frame.size.width);
    }
else {
       
m_webView.frame =
CGRectMake(0,
0, frame.size.width, frame.size.height);
    }

    [UIViewcommitAnimations];
}

/*

 *函数名:rotateScreenToLeft
返回值:void

 描述：屏幕强制左转

 开发者： 2015/7/27

 */
- (void)rotateScreenToLeft {
   
BOOL isStatusBarHidden = [UIApplicationsharedApplication].statusBarHidden;

    [[UIApplicationsharedApplication]
setStatusBarHidden:!isStatusBarHiddenwithAnimation:UIStatusBarAnimationFade];

    //横屏强制转换

    CGRect frame = [UIScreenmainScreen].applicationFrame;
   
CGPoint center = CGPointMake(frame.origin.x +ceil(frame.size.width/2),
frame.origin.y +ceil(frame.size.height/2));

    [[UIApplicationsharedApplication]
setStatusBarOrientation:UIInterfaceOrientationLandscapeRightanimated:YES];

    

    CGFloat duration = [UIApplicationsharedApplication].statusBarOrientationAnimationDuration;

    [UIViewbeginAnimations:nilcontext:nil];

    [UIViewsetAnimationDuration:duration];
   
self.view.center = center;

    self.view.transform =CGAffineTransformRotate(self.view.transform,
-M_PI/2);
   
if (!isStatusBarHidden) {
       
m_webView.frame =
CGRectMake(0,
0, frame.size.height, frame.size.width);
    }
else {
       
m_webView.frame =
CGRectMake(0,
0, frame.size.width, frame.size.height);
    }

    [UIViewcommitAnimations];
}
