ios - 将数据传递到本地 html iOS webview

Question

我试图在 Facebook 登录到我的标签栏 View Controller 后从我的 View Controller 传递，但它给了我这个错误:

'NSInvalidArgumentException', reason: 'Storyboard () doesn't contain a view controller with identifier 'dashBoardViewController''

这是方法:

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
                            user:(id<FBGraphUser>)user {

    NSString *userName = [user first_name];
    NSString *userId = [user id];


    dashBoardViewController *dashBoardViewController =     [self.storyboard instantiateViewControllerWithIdentifier:@"dashBoardViewController"];
    dashBoardViewController.first_name = userName;
    dashBoardViewController.id = userId;
    [self presentModalViewController:dashBoardViewController animated:YES];
}

编辑

//
//  ViewController.m
//  LoginSampleFB
//
//

#import "ViewController.h"
#import "dashBoardViewController.h"
#import "BFPaperTabBarController.h"
#import <FacebookSDK/FacebookSDK.h>


@interface ViewController ()



@end

@implementation ViewController



- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    self.loginButton.delegate = self;
    self.loginButton.readPermissions = @[@"public_profile", @"email", @"publish_actions",];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}





- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
                            user:(id<FBGraphUser>)user {

    NSString *userName = [user first_name];
    NSString *userId = [user id];



    dashBoardViewController *dashBoardViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"dashBoardViewController"];
    dashBoardViewController.first_name = userName;
    dashBoardViewController.id = userId;
    [self presentModalViewController:dashBoardViewController animated:YES];
}



-(void)loginView:(FBLoginView *)loginView handleError:(NSError *)error{
    NSLog(@"%@", [error localizedDescription]);
}


@end

你应该看看这个 stackoverflow 主题，这是同一个问题。

UIStoryboard Couldn't find view controller with identifier

恢复:

1. 检查并确保在 Storyboard中设置了 Controller 类和 Storyboard ID。 (请参阅与我的答案相关的主题中的图片)

   自定义类 |类:dashBoardViewController

   身份 | Storyboard ID:dashBoardViewController

2. 如果是，但仍然无法正常工作，请尝试从 iPhone 模拟器或测试设备中删除您的应用程序，清理您的项目，构建并运行它。

3. 如果错误仍然存​​在:尝试使用 [[UIStoryboard storyboardWithName:@"nameofyourstoryboard"bundle:nil] instantiateViewControllerWithIdentifier:@"dashBoardViewController"] 而不是 self.storyboard。您一定会拥有这样的正确对象。

4. 还是不行？从你的 Storyboard中删除你的 Controller 并尝试重新创建一个新的。有时它会发生...
