Question

我正在創建一個已與Twitter集成的應用程序..並想知道如何創建一個按鈕來添加設備的圖像在tweet.and也想知道要使用的框架，同時還應在代碼

Answer 1

你可以使用Twitter的框架，它包括在內，因爲iOS 5的

和代碼我使用：

- (IBAction)twitter:(id)sender { 
    if([TWTweetComposeViewController canSendTweet]) 
    { 
     NSLog(@"Ready to Tweet."); 
     TWTweetComposeViewController *tweetComposer = [[TWTweetComposeViewController alloc] init]; 
     [tweetComposer setInitialText:[NSString stringWithFormat:@"My message"]]; 
     [tweetComposer addImage:[UIImage imageNamed:@"114x114"]]; 
     [tweetComposer addURL:[NSURL URLWithString:@"http://myPage"]]; 
     tweetComposer.completionHandler = ^(TWTweetComposeViewControllerResult result){ 
     if(result == TWTweetComposeViewControllerResultDone){ 
      NSLog(@"Tweeted."); 

     } else if(result == TWTweetComposeViewControllerResultCancelled) { 
      NSLog(@"Cancelled."); 
     } 

     [self.navigationController dismissViewControllerAnimated:YES completion:nil]; 
     }; 
     [self presentModalViewController:tweetComposer animated:YES]; 
    }else { 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Oops" 
                 message:@"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup" 
                 delegate:nil 
               cancelButtonTitle:@"OK" 
               otherButtonTitles:nil]; 
      [alert show]; 
      [alert release]; 
     } 
}
