1. 除掉UITableView底部多余行及分割線：

self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

2. 隱藏所有的分割線

self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;

3. 設(shè)置分割線橫條的顏色

self.tableview.separatorColor = [UIColor redColor];

4. 設(shè)置分割線橫條的邊距

• 方案1 - cellForRowAtIndexPath代理

//定制表格單元分割線
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    ClientManageCell *cell = [tableView dequeueReusableCellWithIdentifier:kClientTableViewCellIdentifier];

    if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
        [cell setSeparatorInset:UIEdgeInsetsMake(0, 25, 0, 0)];
    }
    //給cell的model賦值
    cell.clientManageModel = self.sectionArr[indexPath.section][indexPath.row];
    return cell;
}

• 方案2 - willDisplayCell代理

//定制表格單元分割線
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
    if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
        [cell setSeparatorInset:UIEdgeInsetsMake(0, 25, 0, 0)];
    }
    
    if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
        [cell setLayoutMargins:UIEdgeInsetsMake(0, 25, 0, 0)];
    }
}

• 方案3 - 對(duì)tableView進(jìn)行設(shè)置

- (void)viewDidLayoutSubviews {
    [super viewDidLayoutSubviews];
    
    self.tableView.tableFooterView = [UIView new];
    if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
        [self.tableView setSeparatorInset:UIEdgeInsetsMake(0,15,0,0)];
    }
    
    if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {
        [self.tableView setLayoutMargins:UIEdgeInsetsMake(0,0,0,0)];
    }
    [self.tableView reloadData];
}
