3.控制器中的設定----高度
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
WorkReportCell * cell = (WorkReportCell *)[self tableView:_tableView cellForRowAtIndexPath:indexPath];
return cell.frame.size.height;
}4.控制器cell顯示-------資料
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
WorkReportCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];
if (!cell) {
cell = [[WorkReportCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
}
cell.imageView1.image = [UIImage imageNamed:@"
