添加索引条sectionIndex
//只要实现这个代理方法,就可以了
//(抽取数组中相同元素)
-(NSArray *)sectionIndexTitlesForTableView: (UITableView *)tableView{
return [ self . dataSourceArray valuesForKeyPath : @"title" ];
}
//索引文字颜色
self . tableView . sectionIndexColor = [UIColor redColor];
//索引条背景颜色
self . tableView . sectionIndexBackgroundColor = [UIColor yellowColor];
cell分割线
1.设置分割线的颜色:tableView.separatorColor = [ UIColor redColor ];
2.设置分割线样式: tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
没有数据的cell不显示
1. tableView.tableFooterView = [ [ UIview alloc] init ];
2. 将分割线样式设置成none,将tableView的style设置成Grounded
高度自动计算
_tabelView2.rowHeight = UITableViewAutomaticDimension;
_tabelView2.estimatedRowHeight = 200;
cell右侧小图标
cell . accessoryType = UITableViewCellAccessoryCheckmark ; //勾
cell.accessoryView = [[UISwitch alloc]init]; //自定义小控件
tableView数据刷新
//整体刷新
[ self . tabelView reloadData] ;
NSArray *indexPaths = @[ [NSIndexPath indexPathforRows : 0 insection : 0] ] ;//获得indexPathss
//刷新 ,使用前提,数组总个数不能改变
[ self . tabelView reloadRowsAtIndexPaths : indexpaths withRowAnimation : UITableViewRowAnimationRight ] ;
//添加刷新
[ self . tabelView insertRowsAtIndexPaths : indexPaths withRowAnimation : UITableViewRowAnimationRight ] ;
//删除刷新
[ self . tabelView deleteRowsAtIndexPaths : indexPaths withRowAnimation : UITableViewRowAnimationRight ] ;
cell左滑删除(系统)
-(void)tableView : (UITableView * ) tableView commitEditingStyle : ( UITableViewCellEditingStyle ) editingStyle forRowAtIndexPath : (NSIndexPath *)indexpath{
return @"只会监听下面的系统默认的delete方法"
/*删除操作*/
}
-(NSString *)tableView : (UITableView * ) tableView titleForDeleteConfirmationButtonForRowAtIndexPath : ( NSIndexPath * )indexPath{
return @" 删除 " ;
}
cell左滑删除(自定义)
14.熟悉cell 左滑动 编辑或删除
Cell中直接子控件是 contentView(红色), contentView的子控件是一个ImageView和两个UIlabel
//可以进行编辑
-(NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewRowAction *saveAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"保存" handler:^ (UITableViewRowAction *_Nonnull action, NSIndexPath * _Nonnull indexPath) {
NSLog(@"关注,想回去得刷新表格,或者将tableView的设置为非编辑模式");
self . tableViedw . editing = NO; }];
saveAction.backgroundColor = [UIColor purpleColor];
UITableViewRowAction *deleteAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"删除" handler:^ (UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) {
NSLog(@"删除");
[self.dataSource removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade]; }];
deleteAction.backgroundColor = [UIColor orangeColor];
return @[deleteAction,saveAction];
}
组头、组尾
//组头(系统)
-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
MySectionHeaderView *header = [[MySectionHeaderView alloc]initWithFrame:CGRectMake(0, 0, CGRectGetWidth(_tb.frame), 100)];
header.tag = section;
[header addTarget:self action:@selector(expend:) forControlEvents:UIControlEventTouchUpInside];
return header;
}
//组尾(自定义)
-(void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section
{
UITableViewHeaderFooterView *headerView = (UITableViewHeaderFooterView *)view;
headerView.backgroundColor = kApp_TintColor;
headerView.textLabel.textColor = [UIColor redColor];
headerView.textLabel.font = [UIFont systemFontOfSize:12.0];
}
表头、表尾
_tb.tableFooterView = view;(View为任何控件,在第一个组头上面,最后一个组尾下面互不影响)
//登录 / 注销按钮
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, kScreen_Width, 44)];
_button = [[UIButton alloc] initWithFrame:CGRectMake((kScreen_Width - 200) / 2 , 4, 200, 36)];
[_button setBackgroundColor:[UIColor redColor]];
[view addSubview:_button];
[_button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
_button.layer.cornerRadius = 18;
_button.clipsToBounds = YES;
[_button setTitle:@"账号管理" forState:UIControlStateNormal];
// [_button setTitle:@"注销" forState:UIControlStateSelected];
[_button addTarget:self action:@selector(loginButtonClick:) forControlEvents:UIControlEventTouchUpInside];
_tb.tableFooterView = view;
