How to support only portrait mode on an iPhone app
提问by Eyal
I have a strange problem in an iPhone app I'm developing. I want my app to support ONLYportrait mode, but for some reason I can't do it (device & simulator).
我正在开发的 iPhone 应用程序中遇到一个奇怪的问题。我希望我的应用程序仅支持纵向模式，但由于某种原因我不能这样做（设备和模拟器）。
To support only portrait mode I did as follow:
为了仅支持纵向模式，我执行了以下操作：
- In the TARGET summary section on Xcode, I chose only portrait.
- All my ViewControllers implements
shouldAutorotateToInterfaceOrientation
- 在 Xcode 的 TARGET summary 部分，我只选择了肖像。
- 我所有的 ViewControllers 实现
shouldAutorotateToInterfaceOrientation
But as I said it won't work, and the strange result is that the app support ALLthe orientations (portrait, upside down, landscape left, landscape right).
Any ideas?
但正如我所说它不会工作，奇怪的结果是该应用程序支持所有方向（纵向、倒置、横向左侧、右侧横向）。
有任何想法吗？
this how I implement shouldAutorotateToInterfaceOrientation
这就是我实施的方式 shouldAutorotateToInterfaceOrientation
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
NSLog(@"Checking orientation %d", interfaceOrientation);
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
I notice just nowthat when I rotate the phone I get this message:
我刚刚注意到，当我旋转手机时，我收到了这条消息：
"Two-stage rotation animation is deprecated. This application should use the smoother single-stage animation."
“不推荐使用两阶段旋转动画。此应用程序应使用更流畅的单阶段动画。”
What does it means?
这是什么意思？

On the Target Summary choose portrait only.
在目标摘要上，仅选择纵向。

Go to info.plist file. Right Click open it as source code. And look for this line. For me in iPad its like this:
转到 info.plist 文件。右键单击将其作为源代码打开。并寻找这条线。对我来说，iPad 是这样的：
<key>UISupportedInterfaceOrientations~ipad</key>
Delete all other orientation and keep the only one which you need..Like this :
删除所有其他方向并保留您唯一需要的方向..像这样：
<array>
<string> UIInterfaceOrientationPortrait </string>
</array>

It is possible to have multiple ViewControllers on the screen. The UITabBarControlleris itself a UIViewController, and it only passes shouldAutorotateToInterfaceOrientation:requests to the viewControllers within if it chooses. The default implementation does this, but if you subclass it, the code XCode generates (as of iOS 5.1) does not.
屏幕上可以有多个 ViewController。TheUITabBarController本身就是 a UIViewController，shouldAutorotateToInterfaceOrientation:如果它选择，它只会将请求传递给其中的 viewControllers 。默认实现是这样做的，但是如果您将其子类化，则 XCode 生成的代码（从 iOS 5.1 开始）不会。

check your plist and make sure the key there is set correctly.
检查您的 plist 并确保那里的密钥设置正确。
