从 SkScene 展示另一个视图控制器 [英] Present another View Controller from SkScene

问题描述

我正在尝试从我的SkScene"中展示另一个 viewController.这是我的主要 viewController(tuViewController)

I'm trying to present another viewController from my "SkScene". This is my main viewController(tuViewController)

代码:

-(void) openTweetSheet{
    FacebookLikeViewDemoViewController *ctrl = [[FacebookLikeViewDemoViewController alloc] initWithNibName:@"FacebookLikeViewDemoViewController" bundle:nil];

    [self presentViewController:ctrl animated:YES completion:nil];
}

这是我的SkScene":

This is my "SkScene":

tuViewController *viewController = [[tuViewController alloc]init];
[viewController openTweetSheet];

我要展示的 viewController 是 FacebookLikeViewDemoViewController，我需要回到SkScene".

And the viewController which i want to present is FacebookLikeViewDemoViewController and i need to have way back to "SkScene".

我得到 sigabrt 错误，我尝试了几种方法来呈现 viewController 但总是失败，有一次我交换到 viewController 但是它完全是黑色的.我读了很多如何执行此操作，但我个人无法弄清楚.感谢您的帮助.

And i got sigabrt error, i tried few ways to present viewController but always with failure, one time i got swap to viewController but it was entirely black. I read a lot how to perform that, but i personally can't figure out. I appreciate your help.

我也尝试过通知中心.

主视图控制器

[[NSNotificationCenter defaultCenter]
 addObserver:self
 selector:@selector(goToGameOverViewController:)
 name:@"GoToGameOverViewController"
 object:nil];

-(void)goToGameOverViewController:(NSNotification *) notification {
    FacebookLikeViewDemoViewController *helpVC = [[FacebookLikeViewDemoViewController alloc]initWithNibName:@"HelpViewController" bundle:nil];
    UIViewController *rootVC = [UIApplication sharedApplication].keyWindow.rootViewController;
    [rootVC presentViewController:helpVC animated:YES completion:nil];
}

SkScene

[[NSNotificationCenter defaultCenter]
 postNotificationName:@"GoToGameOverViewController" object:self];

但我得到了同样的错误.我更喜欢弄清楚为什么通知方式不起作用.

But i got the same error. I prefer to figure out why the way with notification won't work.

推荐答案

我假设你的问题是你正在寻找做一些社交媒体发布.

I assume by your question that you are looking to do some social media posting.

您可以将视图控制器的引用传递给您的 SKScene，也可以使用 NSNotificationCenter 代替.我更喜欢使用后者.

You can either pass a reference for your View Controller to your SKScene or you can use NSNotificationCenter instead. I prefer to use the latter.

首先确保您已将 Social.framework 添加到您的项目中.

First make sure you have added the Social.framework to your project.

将社交框架导入您的视图控制器#import <Social/Social.h>

Import the social framework into your View Controller #import <Social/Social.h>

然后在 View Controller 的 viewDidLoad 方法中添加以下代码:

Then in your View Controller's viewDidLoad method add this code:

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(createTweet:)
                                             name:@"CreateTweet"
                                           object:nil];

接下来将此方法添加到您的视图控制器:

Next add this method to your View Controller:

-(void)createTweet:(NSNotification *)notification
{
    NSDictionary *tweetData = [notification userInfo];
    NSString *tweetText = (NSString *)[tweetData objectForKey:@"tweetText"];
    NSLog(@"%@",tweetText);

    // build your tweet, facebook, etc...
    SLComposeViewController *mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
    [self presentViewController:mySLComposerSheet animated:YES completion:nil];
}

在您的 SKScene 中的适当位置(赢得比赛、输掉比赛等)添加以下代码:

At the appropriate location in your SKScene, (won game, lost game, etc...) add this code:

NSString *tweetText = @"I just beat the last level.";
NSDictionary *userInfo = [NSDictionary dictionaryWithObject:tweetText forKey:@"tweetText"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"CreateTweet" object:self userInfo:userInfo];

上面的代码发送一个带有文本的 NSNotification，你的 View Controller 将获取它并执行指定的方法(在上面的例子中是 createTweet).

The above code sends a NSNotification, with text, which your View Controller will pick up and execute the specified method (which is createTweet in the above example).
