自动布局遇到的问题

Question

我在UIViewContorller里的代码如下：

• (void)viewDidLoad
  {
  [super viewDidLoad];
  [self.view addSubview:self.myTableView];

  [self layoutSubViewConstraints];
  }

• (void)layoutSubViewConstraints
  {
  [self.myTableView mas_makeConstraints:^(MASConstraintMaker *make) {
  make.top.equalTo(self.view.mas_top);
  make.left.equalTo(self.view.mas_left);
  make.right.equalTo(self.view.mas_right);
  make.bottom.equalTo(self.view.mas_bottom);
  }];
  }

运行后，报错：

不知道是因为什么原因导致。
