我的 iOS 应用程序使用 Facebook 登录，但是我的开发团队最近决定将我们所有的应用程序整合到一个具有通用 APP ID 的通用 Facebook 应用程序中。所以我进入我的项目并尝试将我的 FacebookAppID 和 URL 类型更改为正确的 APP ID，但是当我运行应用程序并单击登录按钮时，它会将我重定向到登录 Facebook 上的旧应用程序。我完全不知道为什么会这样，但这是我的 AppDelegate 文件中的内容：
/*
Callback for session changes
*/
- (void)sessionStateChanged:(FBSession *)session
state:(FBSessionState) state
error:(NSError *)error
{
switch (state) {
case FBSessionStateOpen:
if (!error) {
// We have a valid session
NSLog(@"User session found");
}
break;
case FBSessionStateClosed:
case FBSessionStateClosedLoginFailed:
[FBSession.activeSession closeAndClearTokenInformation];
break;
default:
break;
}
[[NSNotificationCenter defaultCenter]
postNotificationName:FBSessionStateChangedNotification
object:session];
if (error) {
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:@"Error"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alertView show];
}
}
/*
* Opens a Facebook session and optionally shows the login UX.
*/
- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {
NSArray *permissions = [[NSArray alloc] initWithObjects:
@"email",
@"user_games_activity",
@"user_location",
@"user_likes",
@"user_birthday",
nil];
return [FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:allowLoginUI
completionHandler:^(FBSession *session,
FBSessionState state,
NSError *error) {
[self sessionStateChanged:session
state:state
error:error];
}];
}
/*
* If we have a valid session at the time of openURL call, we handle
* Facebook transitions by passing the url argument to handleOpenURL
*/
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
// attempt to extract a token from the url
return [FBSession.activeSession handleOpenURL:url];
}
/*
*Logout
*
*/
- (void) closeSession {
[FBSession.activeSession closeAndClearTokenInformation];
}
