I am using Xcode 8 and objective-c. I followed the Facebook guidelines and yet my login button does not switch to a log out button after logging in with my app's Admin user. I'm a bit new to app development so I'm not sure where to look in the Facebook SDK. I read some posts online and they seemed to point to the guidelines (i.e., the issues were solved by following the guidelines closely). I should mention that after logging in again, I get a "you have already authorized {{app}}" message from Facebook with a Cancel and OK button.
Here's the view controller's implementation file:
#import "LoginViewController.h"
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>
@interface LoginViewController ()
@property (weak, nonatomic) IBOutlet FBSDKLoginButton *loginButton;
@end
@implementation LoginViewController
-(void)loginButtonDidLogOut:(FBSDKLoginButton *)loginButton {
}
- (void)loginButton:(FBSDKLoginButton *)loginButton didCompleteWithResult:(FBSDKLoginManagerLoginResult *)result error:(NSError *)error
{
}
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.loginButton.readPermissions = @[@"public_profile", @"email", @"user_friends"];
FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
loginButton.center = self.view.center;
[self.view addSubview:loginButton];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
And the header for the controller view:
#import <UIKit/UIKit.h>
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>
@interface LoginViewController : UIViewController <FBSDKLoginButtonDelegate>
And the AppDelegate's implementation parts that Facebook indicated to change / add:
- (void)applicationDidBecomeActive:(UIApplication *)application {
[FBSDKAppEvents activateApp];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[FBSDKApplicationDelegate sharedInstance] application:application
didFinishLaunchingWithOptions:launchOptions];
return YES;
}
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [[FBSDKApplicationDelegate sharedInstance] application:application
openURL:url
sourceApplication:sourceApplication
annotation:annotation];
}
I basically copied / pasted from Facebook's steps so I'm at a loss as to what to do next. Thanks for any help
