Question

 #import "ViewController.h"




@interface ViewController ()

@end

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

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


@end

我不确定我更改了什么或如何解决这些错误：

找不到'ViewController'的接口声明; 视图控制器不能使用'super，因为它不是根类

Answer 1

可能你忘了子类UIViewController（检查你的标题）：

@interface ViewController : UIViewController

不确定是什么导致了这些错误
