iOS设置某个界面强制横屏,进入就横屏

支持特殊页面的横竖屏，上述文章的强制横屏是不够的，因为状态栏会转，手横屏拿着打开页面页面会乱。需另外添加

1.AppDelegate.m设置：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

//初始设置支持竖屏

       [DeviceUlity sharedInstance].orient = UIInterfaceOrientationMaskPortrait;

}

- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window

{

      return [DeviceUlity sharedInstance].orient;

}

2.进入某个支持横竖屏的viewController,

-(void)loadWithUrl:(NSURL*)url preview:(BOOL)preview

{

//进入时设置支持横竖屏

[DeviceUlity sharedInstance].orient = UIInterfaceOrientationMaskPortrait|UIInterfaceOrientationMaskLandscapeRight;

}

-(void)clickBack:(id)sender

{

//退出页面时设置只支持竖屏

[self.navigationController popViewControllerAnimated:YES];

[DeviceUlity sharedInstance].orient = UIInterfaceOrientationMaskPortrait;

}
