尝试使用ShareKit在Twitter上发帖时收到错误

Question

我正尝试使用sharekit在Twitter和Facebook上发帖。

我有两个按钮，其致电以下两种方法：

- (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正在唯一的工作，当我尝试使用Twitter，我得到以下错误：

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

这很奇怪，因为我使用Facebook的相同方法来设置NavigationViewController的一切工作... 我在SHKConfig.h中一遍又一遍地检查了所有变量

• 认证的OAuth
• 应用型 “浏览器”
• 回调URL中填充的在配置和dev.twitter.com
• Consumerkey OK
• Consumersecret OK

任何一个理念？

编辑。我启用了对Sharekit的调试，这是结果。我仍然没有看到问题出在哪里。

编辑：我得到了答案

[SHK setRootViewController:self.navigationController]; 

需求是：

[SHK setRootViewController:self]; 

的问题是，它需要一个UIViewController，当我传递一个UINavigationViewController。

Answer 1

我们也使用ShareKit。我们还没有穿过这个，但根据docs online，ShareKit将尝试使用导航控制器堆栈来查找您的根视图控制器，然后从那里弹出一个模式视图控制器。它在找不到它时抛出这个错误。

[SHK setRootViewController:myViewController]; 

Answer 2

编辑：

您可以通过使用以下调用手动设置根视图控制器纠正它，我得到了答案

[SHK setRootViewController:self.navigationController]; 

需求是：

[SHK setRootViewController:self]; 

问题是它需要一个UIViewController，而我传递一个UINavigationViewController ...
