本文主要是介绍tableview delegate 详解，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
#pragma TableViewDelegate
分组
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

}
每组的行数
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

cell高度
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.section == 0) {
return 70;
}
else

}
}
cell头的高度
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
if (section == 0)

return 0;
}
else

cell脚的高度
