问题
I'm trying to add either a "share" option to iOS or Android phone galleries, or else another menu option that will perform the same task. I would like to start with iOS if it is possible. For example, if you go to your image gallery on an iPhone or Android phone, there is a share button, and you can choose Email, Picasa, Facebook, Twitter, etc depending on the phone. I need to add something like that to share it to my own web site or app.
If anyone has an idea of even a starting point to start reading that would be helpful!
回答1:
on iOS, you can use ShareKit:
ShareKit : Drop-in Share Features for all iOS Apps
on Android, use ACTION_SEND:
Sharing content in Android using ACTION_SEND Intent

From iOS 6, you can use this approach:
NSString* someText = self.textView.text;
NSArray* dataToShare = @[someText]; // ...or whatever pieces of data you want to share.
UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:^{}];
But on iOS 5, Sharekit is the only way as far as i know.
