故事板导航项目链接到UI控制器

Question

我创建了一个拆分视图项目，在iPhone的故事板上，我将一个栏按钮项目拖到导航右侧并更改样式添加，然后将视图控制器拖到故事板，所以我使用控制拖动来建立链接，并更改uiviewcontroller的自定义类“AddViewController”，当我运行该项目并推动DetailViewController时，它是黑色的视图。

，我已经输入的代码在AddViewController.m

-(void) viewDidAppear:(BOOL)animated 
{ 
    [super viewDidAppear:animated]; 
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone"  bundle:nil]; 
    UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"AddViewController"]; 
    [vc setModalPresentationStyle:UIModalPresentationCurrentContext]; 
    [self presentModalViewController:vc animated:YES]; 
} 

Answer 1

我找到了原因 在我的创造“AddCreateViewController”，我要发表评论的功能。

- (void)loadView 
{ 
    // If you create your views manually, you MUST override this method and use it to create your views. 
    // If you use Interface Builder to create your views, then you must NOT override this method. 
}
