objective-c - Facebook Connect Safari 无法打开页面

Question

您好，我正在使用 faceobok 连接和下面的官方 Facebook 教程: https://developers.facebook.com/docs/mobile/ios/build/现在，当我模拟它时，它会转到 Facebook，然后它会说一些关于该应用程序的信息，然后你按完成。当我按下完成时，sais safari 无法打开该页面，因为它是一个无效地址。这是我的属性(property) list :

这是我的代码:

   - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
return [facebook handleOpenURL:url]; 
}

// For iOS 4.2+ support
 - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
 sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
return [facebook handleOpenURL:url]; 
}

  - (void)fbDidLogin {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
[defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
[defaults synchronize];

  }

  -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:  (NSInteger)buttonIndex       {

if (buttonIndex == 0) {
    // facebook
    facebook = [[Facebook alloc] initWithAppId:@"387500177929927" andDelegate:self];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if ([defaults objectForKey:@"FBAccessTokenKey"] 
        && [defaults objectForKey:@"FBExpirationDateKey"]) {
        facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
        facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
    }

    if (![facebook isSessionValid]) {
        [facebook authorize:nil];
    }
}
 }

Answer 1

您的 CFBundleURLSchemes key 看起来不对，对于该应用，它应该是 fb387500177929927，而不是 387500177929927

Create a new row named URL types with a single item, URL Schemes, containing a single value, fbYOUR_APP_ID (the literal characters fb followed by your app ID).
