如題，添加addChildViewController子viewController仍然無響應- (void)viewDidLoad {
[super viewDidLoad]; // Do any additional setup after loading the view.
UIButton *btn = [[UIButton alloc]initWithFrame:CGRectMake(50, 200, 60, 60)];
[btn setTitle:@"點我" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(btnClick) forControlEvents:UIControlEventTouchUpInside];
[btn setBackgroundColor:[UIColor blackColor]];
[self.view addSubview:btn];
[self addChildViewController:self.imgVC];
}
- (void)btnClick{ NSLog(@"點擊了按鈕");
}// 懶加載- (addImgVC *)imgVC{ if (!_imgVC) {
_imgVC = [[addImgVC alloc]init];
[_imgVC.view setFrame:CGRectMake(0, 50, 375, 62)];
[self.view addSubview:_imgVC.view];
} return _imgVC;
}

你的調用流程還是沒弄清楚，把你的[self.view addSubview:self.imgVC.view]寫在addChildViewController就可以了。因為你懶加載的時候，你寫的流程是先添加了view，然后再添加子控制器，然而正確的流程是先添加子控制器，然后才能添加view
