//注释:从 xib 加载 cell 的方式
方法一：

方法二：
QGLIMGroupListCell *cell = (QGLIMGroupListCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell= (QGLIMGroupListCell *)[[[NSBundle mainBundle] loadNibNamed:@"QGLIMGroupListCell" owner:self options:nil] lastObject]; }
//另外: 从xib 加载视图 UIView
UIView *view = [[[NSBundle mainBundle] loadNibNamed:@"QGLIMGroupListCell" owner:self options:nil] lastObject];
// 获取 view 上的自视图,通过 tag 获取 UIButton *btn = [view viewWithTag:111];
