Since a UITextView is a subclass of UIScrollView, you should be able to create a UIScrollViewDelegate for your UITextView and implement scrollViewDidScroll:. Use the contentOffset to figure out what position the user has scrolled to.

When you add UITextField(or any other UI element) in UIScrollView, then update the content size of your scroll view programatically.
I'm writing a dictionary app to study iOS and I've implemented a UITableView with the alphabet as section titles and an index of all the letters on the right side. It works perfectly, but is it possible for me to display the selected index in a box at the center of the screen? I'm looking at the UITableViewDelegate reference but can't see any methods I might override. Help?
You'd have to manually create a UIView that you put above the UITableView which then shows the letter or whatever you want to present. Make sure not to add it to the table view itself as it's a UIScrollView subclass and your view would be affected by its contentOffset.
When the user presses one index or moves his finger above it, this callback gets called:
-tableView:sectionForSectionIndexTitle:title atIndex:
Use it to change your view's contents and make it visible and set a timer for it to fade out again.
You have to create custom view that display when you click on the cell and in that view you can add Label to show the alphabet which you have selected.
And yes also if you want to display it on center of your screen than give its X and Y coordinates value according to it.hope it helps...
How can I add an UIView as a subview in a cells contentView when the user has tapped the cell, and remove the same UIView when the user taps that cell again?
I am trying to make a list of photos in a UITableView with expand/collapse button. The UIView that I want to add is the container of photo's information. Instagram accomplished it, but I cant figure out how to do it
Please help me guys :)
Thanks!!!
I don't think you want to add a subview to the cell, but you want to add another cell to the already existing table. This way, you can achieve an "expand/collapse" feel to your table by using insertRowsAtIndexPaths:withRowAnimation:
Good luck!
Adding and removing the views in the cell should be easy enough inside didSelectRow, but you may need to keep track of which rows are in what state (big or small) by recording that in a mutable array. The bigger issue you will have is adjusting a cell's height, but look here for that.
Harrr pirates!
I'm trying to make a data entry screen using a UITableViewController. It contains a grouped table view with two sections, each with a few (2 and 4) rows with a UITextField inside them.
When any of the UITextFields become first responder they scroll into view automatically. Great, you would say, but I want to scroll the whole section into view, not just the row containing the UITextField that became first responder.
I don't allow the user to scroll the UITableView by hand and I know to what position it should scroll to display correctly. However, I can't get my UITableViewController to stop automatically scrolling the UITextField into view for me.
Searching StackOverflow I can find a lot of questions about how to resize the UITableView when the keyboard appears, but this doesn't stop the automatic scrolling.
Any suggestions? Your help would be much appreciated!
TableView is basically an extension of scrollView therefore if you want to do the scroll yourself you should use the scrollview API.
Set the contectSize property to the size of the screen without the keyboard and the contentOffset to the location on the table you want to scroll to
Ok. I have made a custom cell for my table, and it contains a text view. When I have multiple lines in the text view, I can scroll up and down, but in doing this the table also scrolls. How can I stop this behaviour? If anyone needs parts of my code or further details, please just ask. I am more than willing.
Thank you for your help
I suggest you to move text edit (write) behavior to another view controller. If you need read-only functionality from it then just increase cell and textView height.
Did you try setting canCancelContentTouches to NO? It's a property of UIScrollView, from which UITableView inherits.
Your custom cell seems to pass on touch events to its container class as well as utilizing them itself. Did you implement any - touchesBegan:, - touchesMoved: or - touchesEnded:?
If you make use of a touch events, you should not pass them on in the responder chain.
When the text view has focus, set scrollEnabled=NO on the table view. You may have to manually remove focus from the text view and restore scrolling when a touch occurs outside the text view.
