定义UITableView 并且遵守两个协议
firstTableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 64, kScreenWidth, kScreenHeight-64) style:UITableViewStylePlain];
firstTableView.separatorStyle = NO;
firstTableView.delegate = self;
firstTableView.dataSource = self;
[self.view addSubview:firstTableView];
//返回每个cell的高度
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
FirstFrame *firstFrame = [frameArr objectAtIndex:indexPath.row];
return firstFrame.heightTableViewCellRow;
}
//cell的内容
/*
FirstData *firstData = [FirstData arrayWithDic:dic];//网络加载json解析为对象
FirstFrame *firstFrame = [[FirstFrame alloc]init];//计算cell高度的累
firstFrame.firstData = firstData;
[firstDataArr addObject:firstData];//数据类数组
[frameArr addObject:firstFrame];//cell高度类数组
*/
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
FirstTableViewCell *cell = [FirstTableViewCell theCorpusWithTableView:tableView];//自定义cell
cell.firstFrame = [frameArr objectAtIndex:indexPath.row];
cell.firstData = [firstDataArr objectAtIndex:indexPath.row];
