UIDocumentInteractionController需要很长时间才能显示选项

Question

我已经使用UIDocumentInteractionController来共享文件,但它在iOS 8 beta 5中25秒后打开菜单选项,并且在iOS 7.1中运行良好.

我已经验证了我粘贴在下面的日志

我不知道问题是什么.

Answer 1

我用过UIActivityViewController，没有发现任何问题。这个bug在iOS 8 Release版本中仍然存在

所以我要UIActivityViewController修复。

我曾经TYOpenInAppActivity在中显示第三方应用程序UIActivityViewController

NSURL *URL = [NSURL fileURLWithPath:filePath];
TTOpenInAppActivity *openInAppActivity = [[TTOpenInAppActivity alloc] initWithView:self.view andBarButtonItem:barButton];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[URL] applicationActivities:@[openInAppActivity]];
    // Create pop up
    self.activityPopoverController = [[UIPopoverController alloc] initWithContentViewController:activityViewController];
    // Store reference to superview (UIPopoverController) to allow dismissal
    openInAppActivity.superViewController = self.activityPopoverController;
    // Show UIActivityViewController in popup
    [self.activityPopoverController presentPopoverFromRect:((UIButton *)sender).frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
