UITableViewCell的选择状态问题

1.给cell增加一个Bool标识属性

2.根据外部传来的标识来确定cell要如何显示 ，重绘cell

-(void)setIsSelectedCell:(BOOL )isSelectedCell

{

       _isSelectedCell = isSelectedCell;

        [selfsetNeedsLayout];

}

-(void)layoutSubviews

{

    [superlayoutSubviews];

    if (self.isSelectedCell) {

        [self.selectedBtnsetImage:[UIImageimageNamed:@"勾"]forState:UIControlStateNormal];

    }else

    {

        [self.selectedBtnsetImage:[UIImageimageNamed:@"勾2"]forState:UIControlStateNormal];

    }

}

3.在外部传入按钮选中状态

#pragma mark -- 选中了cell

-(void)Choose:(UIButton *)btn

{

    PayCell *cell  = [self.tableViewcellForRowAtIndexPath:btn.indexPath];

    cell.isSelectedCell = !cell.isSelectedCell;

    [self.tableViewreloadData];

    

}

大功告成，效果如下
