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];@H_301_5@ 
 
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)
 
 
 
  
And the app crashes with a “MailCompositionService” exception. The
