在你ViewController.m：

NSString *message = @"The Flyer http://flyerdream.tumblr.com"; 
UIImage *image = [UIImage imageNamed:@"flyer"]; 
NSArray *arrayOfActivityItems = [NSArray arrayWithObjects:message, image, nil]; 
UIActivityViewController *activityVC = [[UIActivityViewController alloc] 
             initWithActivityItems:arrayOfActivityItems applicationActivities:nil]; 

[self.navigationController presentViewController:activityVC animated:YES completion:nil];
