问题描述
UIDocumentInteractionController
似乎在iPad模拟器中无法正常运行(iPhone模拟器4.0版,随附XCode 3.2.3,使用iOS版本3.2)。
The UIDocumentInteractionController
appears to be non-functional in iPad Simulator ("iPhone Simulator" version 4.0, shipping with XCode 3.2.3, using iOS Version 3.2).
我有一个简单的示例代码,使用 UIDocumentInteractionController
来展示PDF预览。它适用于设备。在iPad上 presentPreview
只返回NO,不会调用 UIDocumentInteractionController的
委托方法。
I have a simple sample code presenting a PDF preview using UIDocumentInteractionController
. It works on the device. On iPad presentPreview
just returns NO, the UIDocumentInteractionController's
delegate methods are not invoked.
任何提示如何使它工作?
Any hint how to make it work?
推荐答案
在此确认相同的行为:调用 - (BOOL)presentPreviewAnimated:
在模拟器上返回 NO
但在设备上运行。感谢您指出这一点,我花了两个小时一次又一次地检查我的代码。到目前为止还没有解决方案。
Confirming the same behaviour over here: calling - (BOOL)presentPreviewAnimated:
returns NO
on the simulator but works on the device. Thanks for pointing this out, I just spent two hours going over my code again and again. Got no solution so far.
