通过代码给xib加控件，控件是加上去，点击却报错

Question

// 4.创建按钮
BFModuleItem *button = [BFModuleItem buttonWithType:UIButtonTypeCustom];
// 4.1.设置item的frame
CGFloat y = (kCenterCellHeight + kCellVerticalMargin) * index;
button.frame = CGRectMake(kIconWidth, y, kCenterCellWidth - kIconWidth, kIconHeight);
[button addTarget:self action:@selector(rightButtonClick:) forControlEvents:UIControlEventTouchUpInside];
[button setBackgroundColor:[UIColor greenColor]];
[_scrollView addSubview:button];

• (void)rightButtonClick:(BFModuleItem *)item { BFLog(@"bbbbbbb"); }

上面的代码都有写却报这个错误，为什么会去UIViewControllerWrapperView里面找方法，是不是xib连线有问题，可是按钮却有显示出来，哪位大神知道的，麻烦说下，谢谢
