当我获得Facebook数据时，我试图以编程方式从视图控制器传递到另一个，有没有办法做到这一点？ 通过使用我的方法，应用程序崩溃，在日志中我有：

这是代码：
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
user:(id<FBGraphUser>)user {
NSString *userName = user.name;
userName = [userName stringByReplacingOccurrencesOfString:@" " withString:@"%20"];
NSString *userNameOk = userName;
NSString *userId = [user id];
NSString *userEmail = [user objectForKey:@"email"];
NSString *label_name = user.name;
_profilePicture.profileID = ((dashBoardViewController*)self.tabBarController).id;
_profilePicture.layer.cornerRadius = _profilePicture.frame.size.width / 2;
_profilePicture.clipsToBounds = YES;
_profilePicture.layer.borderWidth = 3.0f;
_profilePicture.layer.borderColor = [UIColor whiteColor].CGColor;
//self.lblEmail.text = [user objectForKey:@"email"];
((dashBoardViewController*)self.tabBarController).first_name = userNameOk;
((dashBoardViewController*)self.tabBarController).id = userId;
dashBoardViewController *dashBoardViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"dashBoardViewController"];
dashBoardViewController.first_name = userNameOk;
dashBoardViewController.label_name= userName;
dashBoardViewController.id = userId;
dashBoardViewController.userEmail = userEmail;
[self presentModalViewController:dashBoardViewController animated:YES];
}
修改
