MFMailComposeViewController在iPad上强制纵向方向 [英] MFMailComposeViewController forces Portrait Orientation on iPad

问题描述

我在应用程序电子邮件中使用MFMailComposeViewController，它在纵向模式下工作正常。但是当我支持两种方向的应用程序都处于横向模式时，
使用[self presentModalViewController：mailVC animated：YES];

I am using MFMailComposeViewController for in app email and it works fine in Portrait mode. But when my app which supports both orientation is in landscape mode, using [self presentModalViewController:mailVC animated:YES];

强制我的整个应用程序进入纵向我不想要的模式。

forces my entire app into the portrait mode which I don't want.

我已经尝试了很多东西来覆盖MFMailComposeViewController shouldAutorotateToInterfaceOrientation：方法，让第一个响应者辞职等等，没有多少运气。

I have tried many things from overriding MFMailComposeViewController shouldAutorotateToInterfaceOrientation: methods, resigning the first responder and so on without much luck.

如何让iPad上的MFMailComposeViewController工作？

How can I get MFMailComposeViewController work in Landscape on iPad ?

推荐答案

我遇到了同样的问题并尝试重写，这对我没有帮助。

I had the same problem and tried overriding, that's didn't help me.

尝试将presentModalViewController：发送到应用程序窗口的rootViewController（在AppDelegate中）。

Try to send "presentModalViewController:" to rootViewController of your application window (in AppDelegate).

我认为这对我有用，因为MFMailComposeViewController不能强制rootViewController方向，但可以强制由rootViewController的navigationController推送的viewControllers的方向。

I think that's works for me because MFMailComposeViewController can't force rootViewController orientation, but can force orientation of viewControllers that was pushed by rootViewController's navigationController.

你需要这样的东西：

    [((AppDelegate *)[UIApplication sharedApplication]).window.rootViewController presentViewController:mailVC animated:YES completion:nil];
