Question

嗨我必须在表视图中使用子菜单做菜单。菜单看起来像：
1. News ---|1.1 ---|1.2 ---|1.3 2. Weather 3. Ads 4. Cinema

从服务器下载数据到菜单。

我必须在此菜单中移动单元格。

使用了哪个框架？

Answer 1

使用tableView:indentationLevelForRowAtIndexPath:委托方法查看。考虑为每个菜单部分使用不同的表部分，并根据indexPath.row > 0设置缩进（假设菜单中有2个级别）。

Answer 2

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return self.menus.count;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

return  55;;

}

 - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
return 70;
}

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
return 2;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [[self.menu objectAtIndex:section] objectForKey:@"submenus"];
}


- (UIView*)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {


UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 70)];

headerView.backgroundcolor = [UIColor clearcolor];

UILabel *menuTitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(5, 2, tableView.frame.size.width - 5, 60)];
menuTitleLabel.backgroundColor = [UIColor clearColor];
menuTitleLabel.textColor = [UIColor colorWithRed:68.0/255.0 green:68.0/255.0 blue:68.0/255.0 alpha:1.0];;
menuTitleLabel.text = [[[self.menus objectAtIndex:section] objectForKey:@"title"] uppercaseString];
menuTitleLabel.font = [UIFont fontWithName:@"Roboto-Bold" size:16.0];
[menuTitleLabel setAdjustsFontSizeToFitWidth:YES];
[headerView addSubview:menuTitleLabel];

return headerView;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSArray *submenuArray  = [[self.menus objectAtIndex:indexPath.section] objectForKey:@"submenus"];;

static NSString *CellIdentifier = @"MenuCell";
MenuCell *cell = (MenuCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MenuCell" owner:self options:nil];
    cell = [nib objectAtIndex:0];
    cell.backgroundColor = [UIColor clearColor];
}
cell.title.backgroundColor = [UIColor clearColor];
cell.title.font = [UIFont fontWithName:@"Roboto-Bold" size:16.0];
cell.title.text = [subMenuArray objectAtIndex:indexPath.row]objectForKey:@"title"];
cell.title.textColor = [UIColor colorWithRed:68.0/255.0 green:68.0/255.0 blue:68.0/255.0 alpha:1.0];
return cell;

}
