ios8 – UIActivityViewController在iOS 8中不起作用_app

概述我正在使用UIActivityViewController为我的应用程序分享一些东西.它适用于iOS8之前的任何设备.问题是文本,图像不会显示在iOS 8设备或模拟器中的电子邮件,推特,Facebook中. 这是我的代码： NSString *textObject = @"Test"; NSString *urlString = @"http://test.com"; UIImag 我正在使用UIActivityVIEwController为我的应用程序分享一些东西.它适用于iOS8之前的任何设备.问题是文本,图像不会显示在iOS 8设备或模拟器中的电子邮件,推特,Facebook中.

这是我的代码：

Nsstring *textObject = @"Test";    Nsstring *urlString = @"http://test.com";    UIImage* image = [UIImage imagenamed:@"logo"];    NSURL *url = [NSURL URLWithString:urlString];    NSArray *activityItems = [NSArray arrayWithObjects:textObject,url,image,nil];    UIActivityVIEwController *avc = [[UIActivityVIEwController alloc]                                     initWithActivityItems:activityItems                                     applicationActivitIEs:nil];    avc.excludedActivityTypes = @[UIActivityTypePostToWeibo,UIActivityTypeAssignToContact,UIActivityTypecopytopasteboard ];    [self presentVIEwController:avc animated:YES completion:nil];

我做错了什么吗？谢谢.

编辑：

新的Xcode 6.1和iOS 8.1无法解决问题.它会导致电子邮件崩溃.以下是一些截图(以电子邮件共享为例)：

>在iOS 7中(你可以看到图像)

>在iOS 8(空白屏幕)
