错误：不包含带标识符的视图控制器？

Question

-(void)btnclick1:(UIButton *)sender
{
    NSString *storyboardName=@"Main";

    UIStoryboard* storyboard1 = [UIStoryboard storyboardWithName:storyboardName
                                                         bundle:nil];


    secondViewController *add = [[secondViewController alloc]init];
 add =[storyboard1 instantiateViewControllerWithIdentifier:@"nextseg"];
    [self.view addSubview:add.view];

    [self presentViewController:add
                       animated:YES
                     completion:nil];



}

我收到错误：原因：'故事板（）不包含带有标识符'nextseg'的视图控制器<'

Answer 1

您需要在XIB的MainStoryboard设置中为要使用的xib设置Storyboard ID，请参阅图像。在您的情况下，它应该是@"nextseg"

希望这有帮助。

干杯。

Answer 2

只需将[NSBundle mainBundle]添加到您从中获取故事板的bundle参数。希望这有帮助

-(void)btnclick1:(UIButton *)sender
{
    NSString *storyboardName=@"Main";

    UIStoryboard* storyboard1 = [UIStoryboard storyboardWithName:storyboardName
                                                     bundle:[NSBundle mainBundle]];


    secondViewController *add = [[secondViewController alloc]init];
    add =[storyboard1 instantiateViewControllerWithIdentifier:@"nextseg"];
    [self.view addSubview:add.view];

    [self presentViewController:add
                   animated:YES
                 completion:nil];



}

还要确保你有一个标识符＆＃34; nextseg＆＃34;为您的视图控制器。 ＆＃34; nextseg＆＃34;不应该是通向视图控制器的segue的标识符，但它应该是视图控制器
