如何在仅支持iOS-6横向方向的应用程序中使用UIImagePickerController？ [英] how to use UIImagePickerController in an app which support Landscape orientation only in iOS-6?

问题描述

我正在开发一款仅支持横向定位的应用。它使用 UIImagePickerController 从库中选择图像和/或视频。应用程序在iOS-5或之前运行良好但在我尝试呈现图像选择器控制器时它会崩溃。它在崩溃后发出以下消息：

I am developing an app which supports Landscape orientation only. It uses an UIImagePickerController to pick images and/or videos from the library. App is functioning fine in iOS-5 or before but it gets crashed when I try to present image picker controller.It gives the following message after crashing:

* 由于未捕获的异常'UIApplicationInvalidInterfaceOrientation'而终止应用程序，原因：'支持的方向与应用程序没有共同的方向，并且shouldAutorotate返回YES'

* Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES'

推荐答案

正如@rocky所说，你必须在你的应用程序中添加Potrait模式才能使用 UIImagePickerController 喜欢这个

As @rocky said you have to add Potrait mode to your application to use UIImagePickerController Like this

或
将此添加到您的仅横向app委托类

or add this to your landscape only app delegate class

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
    return UIInterfaceOrientationMaskAll;
}

和丹尼尔先生的答案 我为您的仅景观应用程序找到了一个很好的解决方案，
，因为您只需要支持应用程序的景观，您只需要为添加类别UINavigationController 像这样

@implementation UINavigationController (LandscapeOnly)

- (NSUInteger) supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskLandscape;
}
@end

并将其添加到viewControllers，它适用于我。

and add this to your viewControllers, it works for me.
