How to know what activityType is used?

Question

I'm using UIActivityViewController for social sharing purposes, and I need to log what social network has being used. I know that I should use typedef void (^UIActivityViewControllerCompletionHandler)(NSString *activityType, BOOL completed); and activityType will give me the string that i need, but I don't know how to implement syntactically. Please, can anyone help me get the direction, I'm very newbie.

Answer 1

Ok, for those who need syntax on how to get activityType

[yourUIActivityViewController setCompletionHandler:^(NSString *activityType, BOOL completed) {
        NSLog(@"activity: %@ isCompleted: %d", activityType, completed);
}];
