facebook集成iphone

Question

我嘗試將facebook api集成到我的應用程序中以發佈到牆上。 現在我在我的appdelegate集成代碼，但我不知道在這行收到此errore： 「initWithAppId：未找到」

AppDelegate.h

#import <UIKit/UIKit.h> 
#import "FBConnect.h" 
#import "Facebook.h" 

@interface AppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> { 
    UIWindow *window; 
    UITabBarController *tabBarController; 
    Facebook *facebook; 
} 

@property (retain, nonatomic) IBOutlet UIWindow *window; 
@property (retain, nonatomic) IBOutlet UITabBarController *tabBarController; 
@property (retain, nonatomic) Facebook *facebook; 

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 

    [self.window addSubview:self.tabBarController.view]; 

    facebook = [[Facebook alloc] initWithAppId:@"168377643283604"]; 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    if ([defaults objectForKey:@"FBAccessTokenKey"] && [defaults objectForKey:@"FBExpirationDateKey"]) { 
     facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"]; 
     facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"]; 
    } 
    [self.window makeKeyAndVisible]; 

    return YES; 
    } 

Answer 1

試試這個：

facebook = [[Facebook alloc] initWithAppId:@"YOUR_APP_ID" andDelegate:self]; 

而不是

facebook = [[Facebook alloc] initWithAppId:@"YOUR_APP_ID" ]; 

，不要忘記在.plist文件中添加YOUR APP ID了。

補充一點：

@interface AppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate,FBSessionDelegate>
