我正在使用Xcode 8和objective-c。我遵循Facebook的指引，但登录按钮后，我的登录按钮不会切换到注销按钮后，我的应用程序的管理员用户。我对应用程序开发有点新，所以我不确定在Facebook SDK中看什么。我在网上阅读了一些帖子，他们似乎指出了这些准则（即通过严格遵循准则解决了这些问题）。我应该提到，在再次登录后，我会收到一个“您已经从Facebook授权{{app}}”的消息，并显示“取消”和“确定”按钮。Facebook登录按钮不会更改为iOS中的注销按钮（Xcode 8）
这里的视图控制器的实现文件：
#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
和一个控制器查看标题：
#import <UIKit/UIKit.h>
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>
@interface LoginViewController : UIViewController <FBSDKLoginButtonDelegate>
而且AppDelegate中的执行部分，Facebook的指示改变/添加：
- (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];
}
我基本上从Facebook的步骤复制/粘贴，所以我在下一步该做什么。感谢您的帮助
