iOS tableViewCell 分隔线/最后一行隐藏/全屏分

//调整边距

Swift ： UIEdgeInsetsZero 为全屏显示
 //cell 扩展
extension UITableViewCell{
    /** 让cell分割线满屏*/
    func onSeparatorInsetZero(){
        self.layoutMargins = UIEdgeInsets.zero
        self.separatorInset = UIEdgeInsets.zero
    }
    
    //隐藏分割线
    func onSeparatorNone(){
        self.layoutMargins = UIEdgeInsets(top: 0, left: kScreen_width, bottom: 0, right: 0)
        self.separatorInset = UIEdgeInsets(top: 0, left: kScreen_width, bottom: 0, right: 0)
    }
}

 UIEdgeInsetsMake(0, kScreenWidth, 0, 0) 这个是隐藏某一行

-(void)setLastCellSeperatorToLeft:(UITableViewCell*)cell
{
    if([cell respondsToSelector:@selector(setSeparatorInset:)]) {
        [cell setSeparatorInset:UIEdgeInsetsMake(0, kScreenWidth, 0, 0)];
       //UIEdgeInsetsZero 
    }

    if([cell respondsToSelector:@selector(setLayoutMargins:)]) {
        [cell setLayoutMargins:UIEdgeInsetsMake(0, kScreenWidth, 0, 0)];
    }

    if([cell respondsToSelector:@selector(setPreservesSuperviewLayoutMargins:)]){
        [cell setPreservesSuperviewLayoutMargins:NO];
    }

}

//调用
-(UITableViewCell* )tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath {
    YMMeCell* cell = [YMMeCell shareCell];
    cell.titlLabel.text = self.titlesArr[indexPath.section][indexPath.row];
    cell.iconImgView.image = [UIImage imageNamed:self.iconsArr[indexPath.section][indexPath.row]];

    //最后一行分割线顶头显示
    NSArray* sectTitlArr = self.titlesArr[indexPath.section];
    if(indexPath.row == sectTitlArr.count-1) {
        [self setLastCellSeperatorToLeft:cell] ;
    }
    return cell;
}



//或者在自定义cell里面，在awakeFromNib 添加代码
- (void)awakeFromNib {
    [super awakeFromNib];
    [self setSeparatorInset:UIEdgeInsetsMake(0, kScreenWidth, 0, 0)];
    [self setLayoutMargins:UIEdgeInsetsMake(0, kScreenWidth, 0, 0)];
}
