objective-c – Facebook Connect Safari无法打开页面

这是我的代码：

- (BOOL)application:(UIApplication *)application handLeopenURL:(NSURL *)url {
return [facebook handLeopenURL:url]; 
}

// For iOS 4.2+ support
 - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
 sourceApplication:(NSString *)sourceApplication Annotation:(id)Annotation {
return [facebook handLeopenURL:url]; 
}

  - (void)fbDidLogin {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[facebook accessToken] forKey:@"FBACcessTokenKey"];
[defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
[defaults synchronize];

  }

  -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonATindex:  (NSInteger)buttonIndex       {

if (buttonIndex == 0) {
    // facebook
    facebook = [[Facebook alloc] initWithAppId:@"387500177929927" andDelegate:self];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if ([defaults objectForKey:@"FBACcessTokenKey"] 
        && [defaults objectForKey:@"FBExpirationDateKey"]) {
        facebook.accessToken = [defaults objectForKey:@"FBACcessTokenKey"];
        facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
    }

    if (![facebook isSessionValid]) {
        [facebook authorize:nil];
    }
}
 }
