ios - TabBarController : Orienting views in different orientations
<p><p>我无法保持当前的 View 方向。在下面的设置中，我已经能够将第一个 ViewController 锁定为纵向，将第二个 ViewController 锁定为横向或纵向。但是，当我将第二个导航 Controller /rootviewcontroller 添加到选项卡 Controller 时，整个项目的所有 View 都将变为横向和纵向。无论我是否在第一个导航 Controller 到第二个导航 Controller 中实现相同的代码，都会发生这种情况</p>
<p><strong>我希望能够保留我当前的 ViewController 方向，同时添加一个额外的 navcontroller>viewcontroller</strong></p>
<p>我在 Storyboard 中有以下设置:
<img src="/image/DSwhF.png" alt="enter image description here"/> </p>
<p>这就是我想要实现的目标:
<img src="/image/YEz40.png" alt="enter image description here"/> </p>
<p><strong>tabbarcontroller应该支持所有方向，nav Controller 支持所有方向，第一个 ViewController 和表格 ViewController 只支持纵向，第二个 ViewController 支持横向和纵向。</strong></p >
<p>这里是每个当前 ViewController 的方法</p>
<p><strong>TabViewController.m</strong></p>
<pre><code>-(BOOL)shouldAutorotate
{
return [ shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [ supportedInterfaceOrientations];
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [ preferredInterfaceOrientationForPresentation];
}
</code></pre>
<p><strong>NavController.m</strong></p>
<pre><code>-(BOOL)shouldAutorotate
{
return [ shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [ supportedInterfaceOrientations];
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [ preferredInterfaceOrientationForPresentation];
}
</code></pre>
<p><strong>First View Controller.m</strong></p>
<pre><code>-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
</code></pre>
<p><strong>第二 ViewController .m</strong></p>
<pre><code>-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
</code></pre>
<p><strong>在解决此问题时，我将不胜感激。它已成为我存在的祸根</strong></p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您似乎已经将导航和标签栏 Controller 子类化了。您可以在运行时使用它们的委托(delegate)协议(protocol)来控制方向，而不是这样做。<br/></p>
<pre><code>– tabBarControllerSupportedInterfaceOrientations:
– tabBarControllerPreferredInterfaceOrientationForPresentation:
</code></pre>
<p>和</p>
<pre><code>– navigationControllerPreferredInterfaceOrientationForPresentation:
– navigationControllerSupportedInterfaceOrientations:
</code></pre>
<p>你可以把你的逻辑放在那些我认为有一个更清晰的实现而不是子类化的方法中。容器 ViewController 通常接管单个 vc 旋转实现。</p></p>
