Question

我正在尝试使用sharekit在Twitter和Facebook上发布。

我有两个按钮，它们调用以下两种方法：

- (IBAction) shareOnFacebook:(id)sender
{
    // Create the item to share 
    NSString *someText = @"Share on Facebook.";
    SHKItem *item = [SHKItem text:someText];

    // Share the item
    [[SHK currentHelper] setRootViewController:self.navigationController];
    [SHKFacebook shareItem:item];
}

- (IBAction) shareOnTwitter:(id)sender
{
    // Create the item to share 
    NSString *someText = @"Share on Twitter.";
    SHKItem *item = [SHKItem text:someText];

    //tried both methods to set navigationcontroller!
    [[SHK currentHelper] setRootViewController:self.navigationController];
    [SHK setRootViewController:self.navigationController];  

    [SHKTwitter shareItem:item];
}

Facebook正在运作，当我尝试使用Twitter时，我收到以下错误：

2011-05-31 10:20:25.928 App[870:707] *** Assertion failure in -[SHK showViewController:], /Users/blaat/Dropbox/App/Classes/ShareKit/Core/SHK.m:112
2011-05-31 10:20:25.975 App[870:707] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'ShareKit: Could not find a root view controller.  You can assign one manually by calling [[SHK currentHelper] setRootViewController:YOURROOTVIEWCONTROLLER].'

这很奇怪，因为我使用相同的方法为Facebook设置NavigationViewController，其中一切正常... 我在SHKConfig.h中反复检查了所有变量

身份验证OAuth
应用程序类型“浏览器”
回调网址在配置和dev.twitter.com中填写相同内容
Consumerkey OK
Consumersecret OK

有人有想法吗？

编辑。我为Sharekit启用了调试，这就是结果。我仍然没有看到问题所在。

编辑：我得到了答案

[SHK setRootViewController:self.navigationController];

需要：

[SHK setRootViewController:self];

问题是它需要UIViewController，而我正在传递UINavigationViewController。

Answer 1

我们也使用ShareKit。我们尚未遇到过这个问题，但根据docs online，ShareKit将尝试使用导航控制器堆栈来查找根视图控制器，然后从那里弹出模态视图控制器。当它找不到时会抛出此错误。

您可以通过使用以下调用手动设置根视图控制器来更正它：

[SHK setRootViewController:myViewController];

Answer 2

编辑：我得到了答案

[SHK setRootViewController:self.navigationController];

需要：

[SHK setRootViewController:self];

问题是它需要一个UIViewController，而我正在传递一个UINavigationViewController ......
