//注释:从 xib 加载 cell 的方式

方法一：

第一步：
[self.collectionView registerNib:[UINib nibWithNibName:@"QGLShareBtnCell" bundle:nil] forCellWithReuseIdentifier:@"QGLShareBtnCell”];
第二步：
QGLShareBtnCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"QGLShareBtnCell" forIndexPath:indexPath];

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];
