What is footer in table view IOS - iphone

What is footer. When we will use that. I have a sample code in which they used method viewForFooterInSection. What it will do... Any idea?

It is used as a view at the end of the section, placed after the cells in the section, and before the header view of the next section.
Here is the appropriate docs link and a photo from that page:

A UITableView can be considered as made of three main elements, a "list" - containing sections and cells, a header and a footer.
The list area can contain from 1 to many sections and in a grouped table view you may also have headers and footers for sections. Assuming you are talking about table footers and not section footers the following is my answer:
The table's footer is what it says on the tin... you might want to use it to display some additional information about the data of the table view.
Check the App Store, Apple display some information about the user who is logged into the store at the bottom of the table view (in some areas).
I sometimes use this footer view as an area to display a UIActivityIndicatorView, and initiate a kind of "fetch more" feature for any API related data.

The UITableViewDelegate protocol allows you to return views for the header and footer of a section. Simply implement this method and return a UILabel filled with the text you want to display.

In viewForFooterInSection you can add customized labels or other objects to display in footer section.
From the below two links you can batter understand.

can I show an index for UITableView (ie sectionIndexTitlesForTableView) without a searchbar?

I am trying to make an bunch of links on the right side of the uitableview to jump to the various sections in the tableview without having a searchbar at the top.
thanks
Sure can. Just implement a couple of methods in your table view’s data source: -sectionIndexTitlesForTableView:, which should return an array of titles, and -tableView:sectionForSectionIndexTitle:atIndex:, which returns the corresponding section once the user clicks on a section title.

Why don't the header views that are returned from viewForHeaderInSection scroll with the rest of the table?

I just implemented the UITableViewDelegate::viewForHeaderInSection method to return a custom view. However, when I run the app and load the table view, I notice that header view remains stationary while the rest of the table cells scroll underneath it. What gives? How do I get it to scroll with the rest of the table?
Thanks for your wisdom!
That's how it's meant to work. The header for a section will stay at the top of the tableview to give the user a sense of which section she is currently in. Then when she scrolls further down into the second section, that section header scrolls into view and then eventually replaces the first section header at the top.
You can see this in the Contacts app on your phone.

You can implement tableView:viewForHeaderInSection: method in table's delegate and create custom view for section header there with title and button (and with whatever else you need).

How to use multi-customized UITableCell in just one UITableView

I am developing an iphone application which have a complicated view is to display stocks information with 3 sections:
- Extended quote which include a chart and stock info (id, price...)
- Other quote info
- News (headline)
They are should be grouped and user can click on its header to expand or collapse the content.
As I know I should use UITableView with customized cells, but I just find out the way to custom all cells in a same way, but here, I need at least 3 different types.
Does anybody have experience about this please tell me what should I do?
Thanks you so much!
After searching in StackOverflow and in the internet, finally, I found the way to show multi-customized UITableCell in just one UITableView by checking the row index / section which you want to custom, create a new UIView then add it into cell content view, also, we can use this way to custom the section header and UITable header.

Multi Column header for a UITableView with Multiple Columns

I have created a UITableView with multiple columns to display a Football League Table. Now what I really need is a header to label each column which will ideally sit at the top of the table view. How would I do this?
Instead of setting it as the header for your first UITableView section, it would make more sense in your situation to set it as the header to your entire table. This can be done with the tableHeaderView property of UITableView. For example:
UIView *myHeaderView = ...
[myTableView setTableHeaderView:myHeaderView];
You could create a custom UIView and set it as the first section header of your UITableView. Return it in your UITableViewDelegate's tableView:viewForHeaderInSection: method. You simply need to design it so that it aligns with the "columns" inside your custom cells.
This is sort of a weird interface for an iPhone app, assuming you are trying to replicate the look and feel of an HTML table, with headings, cells and etc.
If this is what you want, why not just use a UIWebView object to display your table?
