使用这个框架后代码强制横屏失败

[Jijingcheng]

AppDelegate *appDelegate = (AppDelegate *)[UIApplication sharedApplication].delegate; // 打开横屏开关 appDelegate.allowRotation = YES; // 调用转屏代码 [UIDevice deviceMandatoryLandscapeWithNewOrientation:UIInterfaceOrientationLandscapeRight];

/// 输入要强制转屏的方向 /// @param interfaceOrientation 转屏的方向

• (void)deviceMandatoryLandscapeWithNewOrientation:(UIInterfaceOrientation)interfaceOrientation {

  NSNumber *resetOrientationTarget = [NSNumber numberWithInt:UIInterfaceOrientationUnknown];

  [[UIDevice currentDevice] setValue:resetOrientationTarget forKey:@"orientation"];

  // 将输入的转屏方向（枚举）转换成Int类型 int orientation = (int)interfaceOrientation;

  // 对象包装 NSNumber *orientationTarget = [NSNumber numberWithInt:orientation];

  // 实现横竖屏旋转 [[UIDevice currentDevice] setValue:orientationTarget forKey:@"orientation"]; }

这个库没有涉及到屏幕的方向
