问题 So for example, if the user wants to share with twitter, the text would be different than if a user chooses to share with email. How would I code that with initWithActivityItems?: UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil]; 回答1: Instead of objectsToShare , supply an object that adopts the UIActivityItemSource protocol.

问题 Apparently iOS8 by default adds a "iCloud Photo Sharing" activity to activity views in iOS8 and I haven't found any useful documentation regarding it, especially how to explicitly remove it (going into the "More" option allows the user to toggle showing/hiding it, but for our app we want to completely disallow this option).
