facebook - ParseFacebookUtilsV4::initializeFacebookWithApplicationLaunchOptions issue in IOS using Parse/FB SDK -

-

i still using objective-c in project, since legacy one. using parse before , trying add fb integration. managed make compile - these have installed via cocoapods.

using bolts (1.2.0) installing fbsdkcorekit (4.3.0) installing fbsdkloginkit (4.3.0) using parse (1.7.5) installing parsefacebookutilsv4 (1.7.5)

here code.

firstviewcontroller

-(void) viewdidappear:(bool)animated {     // additional setup after loading view, typically nib.     if (![pfuser currentuser] || // check if user cached         ![pffacebookutils islinkedwithuser:[pfuser currentuser]]) { // check if user linked facebook          pfloginviewcontroller *logincontroller = [[pfloginviewcontroller alloc] init];      logincontroller.fields = (pfloginfieldsusernameandpassword      | pfloginfieldsfacebook      | pfloginfieldsdismissbutton);      [self presentviewcontroller:logincontroller animated:yes completion:nil];         [self presentviewcontroller:loginviewcontroller animated:yes completion:null];      } else {         nslog(@"user cached , showing content.");     } }

when view shows , click on log-in facebook, have error.

*** terminating app due uncaught exception 'nsinternalinconsistencyexception', reason: 'you must initialize pffacebookutils call +initializefacebookwithapplicationlaunchoptions'

if add on appdelegate, [pffacebookutils initializefacebookwithapplicationlaunchoptions:launchoptions];

i compilation issue - no known class.

based on this, should add temporary hack in pffacebookutils, method initializefacebookwithapplicationlaunchoptions not exist in file.

i tried adding in appdelegate.

[pffacebookutils initializefacebook];

in case, error :

+[pffacebookutils initializefacebook]: unrecognized selector sent class 0x10024f420 *** terminating app due uncaught exception 'nsinvalidargumentexception', reason: '+[pffacebookutils initializefacebook]: unrecognized selector sent class 0x10024f420'

any ideas/solutions?

make sure you're importing v4 of framework

#import <parsefacebookutilsv4/pffacebookutils.h>

it's subtle, important difference, , will, reason, compile importing

#import <parsefacebookutils/pffacebookutils.h>

especially if switched regular fb utils.
