我有一个标签栏应用程序,一切正常。我可以旋转设备,并且在各种Tab Bar View控制器上都能正常工作。
las,有人建议几个视图控制器需要一个帮助页面。为此,我创建了一个新的ViewController,其中包含UIWebView(可以将帮助内置到HTML文件中)。
我创建新的“ HelpViewController”,如下所示:
mpHelpPage = [[[HelpPageViewController alloc] init];
[mTabBarController.view addSubview:mpHelpPage.view];
[mpHelpPage保留];
mpHelpPage.view.alpha = 0.75f;
当我处于肖像模式时,这将没有任何问题地显示帮助页面。不幸的是,当我处于横向模式并执行上面的代码时,它在Portrait中添加了HelpViewController(这意味着它从屏幕底部伸出)。
这样,当我在上面分配ViewController时,我需要某种方法来告诉ViewController旋转到当前设备方向。
但是,我对如何使它做到这一点感到困惑。任何帮助将非常感激! 
我通过在viewWillAppear中放置方向检查来解决这种烦恼:
如果(self.interfaceOrientation == UIInterfaceOrientationPortrait ||
self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown){
//自定义代码或调用willRotate
}其他{
//自定义代码或调用willRotate
}
如果您愿意,也可以这样做
如果(UIDeviceOrientationIsPortrait(self.interfaceOrientation)){
//自定义代码或调用willRotate
}其他{
//自定义代码或调用willRotate
}
|
您应该在ViewController的willRotateToInterfaceOrientation:duration:中设置子视图的帧属性
或者您编写自己的视图并在视图的layoutSubviews中设置框架属性
添加的子视图应处理其子视图的布局。
|
由于您已将HelpViewController添加为子视图,并且没有UIViewController对其进行控制,因此不会调整其大小。您可以通过检测当前UIViewController的shouldAutorotateToInterfaceOrientation:方法中方向的变化来手动调整HelpViewController的视图大小。此方法将当前方向作为其参数,因此只需检查哪个是当前方向,并相应地将框架设置为:
-(BOOL)应该AutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if((interfaceOrientation == UIInterfaceOrientationLandscapeLeft)||(interfaceOrientation == UIInterfaceOrientationLandscapeRight))
mpHelpPage.view.frame = CGRectMake(0,0,480,300);
其他
mpHelpPage.view.frame = CGRectMake(0,0,320,460);
返回是;
}
或者,不要将HelpViewController添加为子视图,请尝试[self.navigationController pushViewController:HelpViewController animation:YES];
