Question

我刚开始编写应用程序等等。所以我的第一个应用程序是一个带有计时器功能的“简单”游戏。我的问题是这样的：我想给用户一个功能，他可以在Twitter和Facebook上分享他的积分，但游戏点的输出总是0 ..我想解决这个问题并需要你的帮助。< br />

*对不起，我来自德国，所以这里是翻译：

“KlickMich” - ＆gt; “TapMe”
“Zeit” - ＆gt; “时代”
“Punktestand” - ＆gt; “点”
“Die Zeit ist um” - ＆gt; “时间到了”
“Du hast 11 Punkte erzielt” - ＆gt; “你得了11分” “Auf Facebook teilen” - ＆gt; “在Facebook上分享”
“Auf Twitter teilen” - ＆gt; “在Twitter上分享”
“Nochmal spielen” - ＆gt; “再玩一次”
“Habe gerade 0 Punkte in KlickMich erreicht ......” - ＆gt; “只是在TapMe中得了0分......”

期待您的反应：）

我查看了您的代码。您首先重置计时器，然后发送得分以在Twitter上分享。

首先分享Twitter，然后你必须像这样调用setupGame方法：

 - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
 {
    if (buttonIndex == 1)
    {
       [self postToFacebook]; 
    }  
    else if (buttonIndex == 2)
    {
       [self postToTwitter];
    }

   [self setupGame]; // after share you can reset
 }

并将此方法称为-(void)postToTwitter，而不是- (IBAction)postToTwitter。因为没有与该方法的连接。你正在调用该方法而不是用按钮动作连接。

这是你要求的答案。请仔细阅读：

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
  if (buttonIndex == 0)
  {
    [self setupGame];
    NSLog(@"Cancel..");
  }
  else if (buttonIndex == 1)
  {
    NSLog(@"Facebook..");
    [self postToFacebook];
  }
  else if (buttonIndex == 2)
  {
    NSLog(@"Twitter..");
    [self postToTwitter];
  }
}
- (void)postToTwitter
{
   SLComposeViewController *tweetSheet=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
//     if([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
//     {
     SLComposeViewControllerCompletionHandler __block    completionHandler=^(SLComposeViewControllerResult result){

      [tweetSheet dismissViewControllerAnimated:YES completion:nil];

        switch(result){
            case SLComposeViewControllerResultCancelled:
            default:
            {
                NSLog(@"Cancel");
                [self setupGame];
            }
                break;
            case SLComposeViewControllerResultDone:
            {
                NSLog(@"Post");
                [self setupGame];
            }
                break;
        }
    };

    [tweetSheet setInitialText:[NSString stringWithFormat:@"Habe gerade %li Punkte in KlickMich erreicht...",(long)count]];
    [tweetSheet setCompletionHandler:completionHandler];
    [self presentViewController:tweetSheet animated:YES completion:nil];
  //}

 }
