Question

我正在创建一个与 Twitter 集成的应用程序。我想知道如何创建一个按钮来在推文中添加设备图像。我还想知道使用哪个框架以及还有代码在哪里

Answer 1

你可以只使用 twitter 框架，它是从 iOS 5 开始包含的

我使用的代码:

- (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];
        }
}
