I tried below code, but it is working with mistakes. 我尝试了下面的代码,但是它在处理错误。
- (void) openActiveSessionWithPermissions: (NSArray *) arr
{
if ([FBSession activeSession].state == FBSessionStateCreatedTokenLoaded){
[self openWithUI:NO permissions:arr];
} else if ([FBSession activeSession].state == FBSessionStateOpen || [FBSession activeSession].state == FBSessionStateOpenTokenExtended){
[[FBSession activeSession] closeAndClearTokenInformation];
} else {
[[FBSession activeSession] closeAndClearTokenInformation];
[self openWithUI:YES permissions:arr];
}
}
- (void) openWithUI: (BOOL) UI permissions: (NSArray *) permissions
{
[FBSession openActiveSessionWithReadPermissions:permissions allowLoginUI:UI completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
if (error) {
[self.delegate didReceieveError:[error description]];
} else {
[self.delegate didTakeAccessToken:session.accessTokenData.accessToken];
}
}];
}

{
if (FBSession.activeSession.isOpen)
{
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error)
{
