I have a UIViewController with a view, containing a UITableView (myTableView) and some buttons. myTableView also has a searchbar. The moment I start searching, myTableView is covered by a new tableview with the search results. Since myTableView is only covering half the screen, and the new tableview covers the entire screen, I have a problem. How can I set the new UITableView to only cover the same part of the screen as myTableView?
Sounds like you may be using UISearchDisplayController, which contains a UITableView to display search results on. If you want to roll your own, just use a UISearchBar and its delegate methods to populate your own table instead of the included results view.

I am building an app that requires a tableview control so that users can select multiple rows and act upon them in some way. I find it easy to load my data and display it using the UITableViewController but it seems when I do it this way I am unable to place any other controls on the page, such as a toolbar to give the user some actions to perform on the selected rows. I can place a toolbar control on the form in the storyboard, but it doesn't render in the emulator.
Using a UIViewController and placing a TableView on it seems to come with its own set of confusing challenges (that will make total sense once I conquer them).
Is there any advice for a smooth way of getting a table view with toolbar controls? Thanks!
don't use a TableViewController. Use a Standard ViewController, then add a UITableView to it, and adjust the size. This way you will be able to do whatever else you want on that view without limiting yourself to the tableView only functionality.
When you do this make sure you add the datasource and delegate to the connected table. Then add cellForRowAtIndex, number of sections, number of rows, and whatever other delegate methods you need for your table.
Good luck
Is there any advice for a smooth way of getting a table view with toolbar controls?
Yes there are few ways to accomplish this, one way would be adding a footerview to your tableviewcontroller check these
http://developer.apple.com/
UIButtons on tableFooterView not responding to events
Easier way to add this is using storyboard.
Just drag and drop a view in to your tableviewcontroller, then you can adjust the views size and put anything from objects menu to inside of the view.
Now the problem with that is view will not be stable position at the bottom of the page like a tabbar. Lets say you have only 1 row in your tableview, footer view will go up just below that 1 row, lets say you have hundreds of items in your tableview toolbar will be at the bottom of the rows.
The other solutions for your problem would be either create a custom view and adding it to current view or window (this is little bit adbance),but if you want this just google it.
Or just as you said, create a viewcontroller and put a uitableview inside. Dont forget to add <UITableViewDelegate,UITableViewDataSource> to your .h file and then you can call UItableview delegate methods.\
Good Luck.
I have an UITableView with a single cell that contains an UITextView. When calling -becomeFirstResponder on the UITextView my UITableView gets messed up by the automatic animation. This only occurs when the UITextView has to scroll down for the end of the text.
I already tried disabling scrolling on the UITableView.
Depending on the needs of your interface, you could probably do what you're asking by making the parent view controller an instance of UIViewController instead of UITableViewController (which is what provides that "slide to get out of the way of the keyboard" behavior).
Indeed, if your UI consists solely of a text view, you probably don't need a table view at all.
I'm developing an app and I need a view with these elements:
- UITableView
- UITextField and UIButton
- TabBar
As you can guess, I am developing a chat, but when I put the elements in the .xib, I can't show de layer: UITextField and UIButton. If I put them without a view, they dont appear.
If I put a view under the table, and in that view I put the text and the button I get this error: http://pastebin.com/CKfxijz9 (I put the error there because it's to long)
Thanks in advance
There are some ways of dealing with that, depending on how it should behave. Some of them are:
Provide a table footer or header view that holds the button and
the text field.
Nest the table view into another view. The table
view and the view containing the button and text fielt are on the
same level within the view hierarchy. They are rather siblings than
sub- and superview to each other.
Use a UISlider instead of a table. (However, I personally would use the table.)
Here's an approach I've used in the past (not sure if it's best practice, but it works).
Add your button and textfield to a new view (let's call it, bottomView)
Add bottomView to the superview of your tableview
Set the frame of your bottom view so that it fits to the bottom of the screen (this will make it so your tableview will scroll, but keep your bottomView always attached to the bottom of your mainview)
I have a tableview with custom cells. Each cell has a UITextfield. When the last cell's textfield is clicked, the keyboard pops up and covers it and the table view won't scroll up any further. Is there a property of UITableview that can be set so that the last cell can scroll to half way up the screen?
Thanks in advance
There are a two ways to approach this (that I can think about off the top of my head):
You can use the tableFooterView property of UITableView to set an arbitrary, empty view to be about half the size of your table.
You can add empty cells to the bottom of your table
Both of these approaches will accomplish roughly the same thing, but using the tableFooterView property is probably your best bet.
see Making a UITableView scroll when text field is selected for a list of solution..
Also basing your view controller from UITableViewController (since you say its a table) will provide all this functionality automatically!
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
