Ios Facebook共享对话显示代码=100“；操作无法’；不能完成。”；

共享开放图形故事时会显示错误。 我在developer.facebook上找不到与此相关的文档

调用函数时-

-(void) openGraphTest
{
    NSDictionary* author = [self.video objectForKey:@"author"];
    NSString *description =  [NSString stringWithFormat: @"By %@", [author objectForKey:@"username"]];
    id<FBGraphObject> DiscoverObject =

它会临时打开facebook应用程序，然后返回到调用者应用程序，显示100个错误。

我意识到问题是由于PreviewPropertyname参数不正确引起的，对其进行更改，解决了错误。您能告诉我您将其更改为什么吗？我想弄明白这是什么意思。。这方面的文档很差：\n我记不清了，但它更改了预览属性名称，facebook详细信息中有很多这样的字段。你需要检查一下。还有一个名为preview property的属性。您在哪里更改PreviewPropertyname参数Kakshil？我知道太晚了，但我在Facebook面板中更改了它
