I have UITableView with height of ≤500. Tableview data comes from database. Below UITableView, there is one label and two radio button. The problem is if data in the UITableView is less than its height, then it shows blank space between UITableView and those two radio button. I want to place those label and radio button exactly below tableview. How should I do this ?
This is how my tableview looks
If the table view's height does indeed vary depending on shown content, you could use UITableView's tableFooterView.
For a bit more context see this post for example.
Alternatively you could do this with basic auto-layout by tying your label and radio buttons (that you place as siblings of the table) vertically to the bottom of the table view.
I could also imagine that you may need a section footer. So you may want to have a look at that too.
If you want it to be scrollable, add it as the last row in your table view. You may also go with table view's footer.
If you want it to be sticky at the bottom in case of more rows, go with auto layouts. You may create outlet of table view's height constraint and adjust that accordingly depending on the number of rows. However, this approach is not appreciated.

I have a UITableView which have some cells that will be always be there, one cell with a UICollectionView in it that will act like tabs, and finally one cell with a UITableView in it, whose data will change.
Then when the user selects one of this "tabs", I want to reload the nested table to show the correct data rows (the height of this rows will be dynamic).
I have already achieved that the nested table changes on the collection item selection, but the problem I am facing is that the UITableView inside the cell is not sizing properly.
I have build a sample app just to simplify the views. As you can see in the screenshot, the cell that contains the table is not filling the rest of the screen, so the 10 rows are not visible unless you scroll this table.
What I want is this table to fill the rest of the screen. The user must be able to scroll the main tableview, not the nested one, and still see all of the nested table cells.
I can't do this with multiple sections because I will have a header section that will be always fixed on top, if I had another section, it's header will replace the sticky one on scroll.
I have set the rowHeight of the main UITableView to UITableViewAutomaticDimension and an estimatedRowHeight too. I have pinned it to top, left, right and bottom of the cell's ContentView.
Can you help me with this, please? If it helps, I could upload the sample project and link it here.
Thank you very much!
If you are using autolayout then,
Give height constant to nested table view, create outlet for that height constraint.
When you reload that nested table, you will get that table's content size.
Fetch height from that content size and modify height constraint.
I am working on a project to get custom news feeds from Bing news. I created a custom table view cell and populated various UI items in it. But I am having a hard time to make it occupy the entire screen, it starts from extreme left and ends on the right, leaving large gap from the right margin as show in the image. Can anyone help me out, how to correctly fix it with a detailed explanation of how constraints work in Table views and Tableview cells.
Here' what it looks like in the simulator
Remove previous constraints and add constraint to your UITableView like as shown in below image.
So you UITableView will have 0 margin from edges.
Create a UITableViewController. Just drag drop a TableViewCell into it. Add identifier for that cell and use it. By default it will occupy the whole screen.
In your case I guess you might have added constraints to UITableView. Here what you should do is pin your UITableView to Top,Bottom,Right & Left or make UITableView's width equal to SuperView.
I am looking for how to, in Swift and Interface Builder, create a UITableView in Xcode where the table has a set width (example: padding to left and right edges of superview might be 8). In the table, I want cells to go across the first row. When a new cell can no longer fit in the first row I want it to go to the second row. When a new cell can no longer fit on the second row, I want it to go to the third row, etc. I only want the table to scroll vertically.
If anyone can point me to examples or documentation on this I would greatly appreciate it.
You are looking for UICollectionView.

I have a table with different cells and I need to add a scroller view with special UI in some cells:
I need to develop the UI which you can see in section 0.
So my questions are:
How can I add a scroller view?
How can I load data only for those items which are shown right now?
How can I change the width of "Line" column after scrolling to the right?
I'll answer as best I can with some starting pointers for you...
You need to subclass UITableViewCell and in your subclasses drawRect method you should add a UIScrollView to the contentView.
Not totally sure what you mean here, please expand.
In your new table cell, set it as the delegate of the scroll view you implemented, then you''ll get callbacks when the scrollview scroll with the contentOffset value, which you can use to calculate how much to grow or shrink the line items.
I have a tableview that has a large number of fairly tall dynamic cells. I've tried creating the prototypes for these but I've run out of height room in the view.
I can't seem to extend the height of the table view, (or the view it's in). I also can't create the tableview outside the viewController, give it a larger height, and just link to it.
Suggestions? I know I can create the cells programmatically or from a separate nib, but I'd really like to do it via storyboard.
thanks,
Just figured this out myself. Try this:
Double-click the table almost anywhere except where there's an existing control. You can also double-click on the outer edge of the table.
Note that the table view will show a highlighted section that aligns with the cell you've clicked. You've entered some sort of selection mode.
Now use the mouse to scroll up or down. The cells will shift up or down as if you were running the app.
