I have a dynamically created tableView in XCode which generates cells from an array. Currently, the cells do not fill the entire screen, that's to say that there are empty rows beneath them. How do I get them to fill any screen size for any iOS device at any orientation, please? Also, in another tableview, more array items populate the table - but then I can't scroll to view them all. How do I enable scrolling in a tableview?
So, in summary, how can I get my populated cells to fill the screen of any iOS device? And, how do I enable scrolling?
Thank you very much :) I really need help!
I am unsure of what you are asking because you haven't supplied enough information to determine exactly what task you are attempting to complete. Can you be more specific about what you are trying to do?
I can advise on your request for how to scroll, though. If you want to scroll, you'll have to nest the TableView as a child of a parent ScrollView. You can enable scrolling in the ScrollView, which will then allow you to scroll through the content in the child TableView.

I need advice on the most pragmatic way to layout the following view. As you can see from the image attached, I have a static logo and text that appears at the top of the view, followed by a variable number of items.
Initially, I was going to use a TableView for the variable number of items, that way I would be able to load any given number of cells at runtime.
My problem is that if I drop a tableView onto this view below my static logo and text, when the user scrolls, the static logo and text will remain fixed. I need both the static logo/text AND the tableView to scroll up.
My next inclination is to use a scrollView, inside which I would place my tableView and static logo.
Is this the most pragmatic way to approach the problem? If so, will there be usability issues when scrolling the scrollView vs scrolling the tableView? In my mind this could get messy.
Any advice on the best way to approach this is greatly appreciated.
Using a table view inside of a scroll view is a bad idea and warned against by Apple in their docs. Basically the internal gesture recognizers can conflict and create a clunky user experience. The best path forward would be to go with the tableview (which is a subclass of scroll view) and have two different kinds of cells– one for the logo and one for the repeating contents at the bottom. Make the first cell the logo and adjust the table view's settings to format it to your heart's content.
Is is possible to implement smooth scrolling using both a UIScrollView and placing a UITableView at somewhere starting in the middle of the screen? The UIScrollView contentSize is elongated to accomodate the additional height of the UITableView. The UITableView should be able to contain unlimited and unknown number of rows. Scrolling the entire view downwards will cause the upper non-tableview portion to first disappear and then it scrolls down just like a regular table view.
Put it in another way, I'd like to implement a table with some fixed content before the top row. Think of it like a "header area" for the tables, scrolls up and giving way to the entire table rows.
I probably know that I can implement a TableView and programatically make the first row to contain some fixed images. In this way, it will work as expected. But which is easier to implement?
You really don't want to put the table in a scroll view. When the user scrolls on the table it will not move the underlying scrollview so you won't get the effect you are looking for.
Implement viewForHeaderInSection instead and pass in the view you want to display above the first row, or set tableViewHeader.
I have noticed in the iTunesConnect iOS app, the first and last cells of the grouped UITableView stay on screen even though the other cells are scrolling through them. They also move with the tableview. For example when scrolling to the bottom of the table (moving up), the last cell moves up with the table as it leaves the bottom of its position on screen.
Does anyone have an example of how this could be done? I have tried setting the header and footer views but these scroll off screen when moving the tableView.
Thanks.
I think the best approach would be to use a plain UITableView with Header and Footer set, and "skin"/theme your custom UITableViewCells to look like grouped UITableViewCells.
you'd might want to have a look over here for some pointers on how to achieve this.
Let's say we have a UITableView with some 100 rows, we select a row and after that we scroll the UITableView. The selected row is also scrolled top or bottom direction but I want the selected row to be always visible to the user while scrolling the table. Is it possible ?? please help me out which sample code..(it is same like twitter scrolling)
If you want this, you'll have to write a completely custom tableview from scratch (which I believe was done for Twitter.app). There's no way to do that with the built-in tableview.
I want to put a scroll view inside of the table view cell. I have a number of buttons in one cell of table view and I need to scroll that cell to show the appropriate button.
If you want to use a vertical scroll view then I wouldn't suggest you doing it because, as TechZen wrote, there will be a mess in this case.
If you want the inner scroll view to scroll horizontally then it might be achieved by 2 ways:
Implement a custom table view cell that will include a scroll view inside it.
Add a scroll view as a sub-view to your cell that you will return from tableView:cellForRowAtIndexPath: method.
I suggest you to use the second approach.
There are plenty of examples online. Usually the sub-views are labels or image views, but it is not complicated at all to add a scroll view instead...
I don't think you can do this. It would require nesting of scrollviews which isn't really supported.
Even if it was, it would be very difficult for a user to know which scrollview they were hitting with their pudgy finger. Remember, you don't have the one pixel precision of a mouse on the iPhone. You have an area of at least 15x15 pixels. You don't have a scroll bar but instead just drags anywhere on the screen.
Instead, you should use a master-detail pattern. Selecting the cell in the tableview pushes a detail view which has the scroll view with all the buttons.
Why do you want to do it like this?
I think the best idea is to draw your table view manually above your uiscrollview. I did it, and it works. It just takes more effort and drawing accuracy. But that takes a lot of time. :)
