iOS: -canOpenURL: 失败的 URL: "fbauth2:/" - 错误: 模拟器和设备上"The operation couldn’t be completed. (OSStatus



我使用了那个链接,但我有那个错误消息。不可能知道为什么。我想要的只是一个按钮,单击它即可在iPad上共享本地图像,而无需安装Facebook应用程序。我只希望用户单击按钮,输入他的登录名/密码,发布它,仅此而已。

UIImage *image = [UIImage imageNamed:@"..."];
FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
photo.image = image;
photo.userGenerated = YES;
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
content.photos = @[photo];

appDelegate 中的 openUrl 方法:

- (BOOL) application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
    NSLog(@"url recieved: %@", url);
    NSLog(@"query string: %@", [url query]);
    NSLog(@"host: %@", [url host]);
    NSLog(@"url path: %@", [url path]);
      return YES;
}

我精确地指出该行存在问题:

[[FBSDKApplicationDelegate sharedInstance] application:application
                         didFinishLaunchingWithOptions:launchOptions];
  • 在控制台(模拟器)中执行其他消息错误:
    由于模拟器错误
    ,回退到从 NSUserDefaults 加载访问令牌由于模拟器错误,回退到在 NSUserDefaults 中存储访问令牌

  • 不要在控制台(设备)中执行其他消息错误:
    任务 .<1> 已完成,但出现错误 - 代码:-1001

有关信息,这是我的 plist 键:

提前谢谢。

转到Info.plist并更改 App Transport Security Settings ==> Allow Arbitrary LoadsYES

添加LSApplicationQueriesSchemes
