问题 Was wandering if anyone can offer some insight. For the life of me I can't figure out how to send a UIImage with UIActivityTypeMessage all though some say it is possible.

问题 I am attempting to display an Open In menu via UIDocumentInteractionController and presentOpenInMenuFromBarButtonItem . This does not bring up the UIDocumentInteractionController on screen. The weird thing is that if I replace " OpenIn " with " Options " then it will work as expected. What is causing presentOpenInMenuFromBarButtonItem not to work? Thank you. NSString *fileName = [NSString stringWithFormat:@"%@text.txt", NSTemporaryDirectory()]; [self.textToShare writeToFile:fileName

问题 This is my first question on StackOverflow, so please be patient with me... Here's the problem: I have created a custom Activity for adding bookmarks, which is opened from the UIActivityViewController . On iPhone it is opened as a modal, which is ok. But on iPad I open the UIActivity in a Popover, and I want the custom BookmarkActivity also to be opened in this Popover. The method -(UIViewController *)activityViewController in my UIActivity subclass looks like this: - (UIViewController *

问题 How do I combine a UIActivityViewController and a UIDocumentInteractionController? The Mail app and the Tumblr app seem to compine a UIActivityViewController with a UIDocumentInteractionController because their controllers also show the "Open in" buttons besides the UIActivities. How can I accomplish this? 回答1: Use presentOptionsMenuFromRect:inView:animated: in UIDocumentInteractionController 来源： https://stackoverflow.com/questions/19591028/uiactivityviewcontroller-and
