ios6.0一键分享到新浪微博，facebook，twitter 还有保存打印等

1、添加类库文件  #import <Social/Social.h>

2、点击新浪微博触发事件

- (IBAction)shareToWeibo:(id)sender {
    [slComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
        NSLog(@"start completion block");
        NSString *output;
        switch (result) {
            case SLComposeViewControllerResultCancelled:
                output = @"Action Cancelled";
                break;
            case SLComposeViewControllerResultDone:
                output = @"Post Successfull";
                break;
            default:
                break;
        }
        if (result != SLComposeViewControllerResultCancelled)
        {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Weibo Message" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
            [alert show];
        }
    }];
    
    if([SLComposeViewController isAvailableForServiceType:SLServiceTypeSinaWeibo])
    {
        slComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeSinaWeibo];
        [slComposerSheet setInitialText:self.sharingText];
        [slComposerSheet addImage:self.sharingImage];
        [slComposerSheet addURL:[NSURL URLWithString:@"http://www.weibo.com/"]];
        [self presentViewController:slComposerSheet animated:YES completion:nil];
    }       
}

3、点击twitter按钮

- (IBAction)shareToTwitter:(id)sender {
    [slComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
        NSLog(@"start completion block");
        NSString *output;
        switch (result) {
            case SLComposeViewControllerResultCancelled:
                output = @"Action Cancelled";
                break;
            case SLComposeViewControllerResultDone:
                output = @"Post Successfull";
                break;
            default:
                break;
        }
        if (result != SLComposeViewControllerResultCancelled)
        {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Twitter Message" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
            [alert show];
        }
    }];
    
    if([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
    {
        slComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
        [slComposerSheet setInitialText:self.sharingText];
        [slComposerSheet addImage:self.sharingImage];
        [slComposerSheet addURL:[NSURL URLWithString:@"http://www.twitter.com/"]];
        [self presentViewController:slComposerSheet animated:YES completion:nil];
    }
}

facebook类似，只需改变枚举。

4、分享过多

- (IBAction)shareByActivity:(id)sender {
    NSArray *activityItems;
    
    if (self.sharingImage != nil) {
        activityItems = @[self.sharingText, self.sharingImage];
    } else {
        activityItems = @[self.sharingText];
    }
    
    UIActivityViewController *activityController =
    [[UIActivityViewController alloc] initWithActivityItems:activityItems
                                      applicationActivities:nil];
    
    [self presentViewController:activityController
                       animated:YES completion:nil];
}
