I have a UITableView with some rows in it. Is it possible to show a UIPickerView when tapping on a row in the table?
I want the UIPickerView to change its data depending on which row it the UITableView that is selected.
If you set a delegate set for UITableView then that view will send you the appropriate delegate methods. From there you can reload your picker view. Click here to find out more.

I am creating an app tableview based.
On tableview i have 6 sections. Under those sections there are some rows.
Also i have UIButtons on each section.
Now when i click the UIButton on a particular section it will call an alert with textfield. When i type row name and press ok it will insert the row in that particular section. I have created alert with textfield. But when i try the rest it does not show up the row. What do i do??? I have been stuck in this for a couple of days.
Thanks in advance.
If you are inserting or removing any row or section in your tableView then you need to update your tableView's dataSource and then populate through it in cellForRowAtIndexPath: method by calling `[self.tableView reloadData].
Is there a way to add rows to a UITableView by tapping a row, then the table animating to display some 'hidden' rows of data? Much in the same way you can tap the nearest day in the iOS 5 weather app and show an hourly view of the weather?
How about the:
- (void)insertRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation
method of the UITableView class?
Basically, on a row press:
provide a different height for your row
tableView.beginUpdates
tableView.endUpdates
You'll need to implement a custom cell. The hidden display elements should be already drawn in the custom cell. When beginUpdates triggers tableView: heightForRowAtIndexPath: you should provide your updated height. After endUpdates is called, this will cause the tableView to slide down your existing cell.
So I have a UITableView (its in a UIPopOverController if that matters), and I want the user to be able to edit the content of the tableView. I added a UINaviagationController, the tableView also has a title and an edit button. Essentially what I'm asking is, when the user taps the edit button, how can I add like UITextViews to some of the tableViews and in one of the cells, a UISegmentControl and a UITextView.
Thanks in advance
just add them as subviews of the cell, set correct frame to make subviews inside the cell
I am trying to implement editable cell in tableview, just like what is available in new contact screen in iphone and ipod
Right now I have two labels in a cell, one of which will remain same all the time and the other one will be editable. Do I need to change this label to textfield.
one more thing I also want that when i click one such cell it should pop a picker view and and set the picerview value.
#Umang in order to make your UITableView cells editable I suggest you to give UITextField to your cell....for more help how to do it take help from already asked How to make tableviewcell text editable on touch in iPhone SDK?
Yes you should add a UITextField to the cell if you want to editable. but
from your question i understand that you want to set a piker value to the cell label.
in this case you don't need to change the cell.
you should add the pop the picker in the didSelectRow method, and change the cell label to its result.
if you dont know how just ask and i will try to help.
Yeah, you will need to change it to a textfield. UILabel is non-editable by design.
I am populating a UITableViewController's UITableView through code only. At the bottom of the table I wish to position a button that scrolls into view as the user scrolls to the bottom of the table.
When in the UITableViewController life cycle should I populate the table footer with a button? viewDidLoad?
p.s. I wish to avoid using section footers in the UITableView.
Yes, viewDidLoad is the correct place. It's not a stone-set rule though - I have change footer view in many different situations, such as after rotation in didRotateFromInterfaceOrientation.
Note that the view will be repositioned to location immediately below the last row, so if you want to provide a margin or centering for your button I suggest adding a plan UIVIew as footer, and then add your button(s) into that UIView.
Yes, put it in viewDidLoad. Here is some sample code.
You can just set the tableFooterView property of a UITableView to your button.
