如何从随机开关案例中调用文本？

Question

- (IBAction)postToTwitter:(id)sender {
 if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
{

SLComposeViewController *tweetSheet = [SLComposeViewController

composeViewControllerForServiceType:SLServiceTypeTwitter];

[tweetSheet setInitialText:@"This is the text which should be called from switch case"];

 [self presentViewController:tweetSheet animated:YES completion:nil];

 }

}

////这是我的转换案例，只是为了给你一个想法

-(IBAction) random {
int text = arc4random() % 3;
switch (text) {

    case 0:

 textview.text = @"Text example 1";

        break;

    case 1:

        textview.text = @"Text example 2";

        break;

    case 2:

        textview.text = @"Text example 3";

        break;

default:

        break;

   }

}

我想在切换案例发生变化时，将文本示例1，文本示例2和文本示例3输入到我的Twit内容中。 请帮忙！！！ ：'（

[controller setInitialText:textview.text];
