在您的ViewController.m中:

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];
