UItableView style not changing. I have a tableView controller as one of the tabs of my tab bar controller. I am not able to change the style of UItableView to grouped.
Please help,
You must specify the Tableview's style upon creation. Either in IB or by using the method
tableView = [[UITableView alloc] initWithFrame:CGRectMake(0,0,320,416) style:UITableViewStyleGrouped];
I would create a new tableViewController and make sure to enable the "also create xib"-like option when giving the tableviewcontroller a name. Copy paste all youre old tablviewcontroller code to the new one and add the xib to the tab window..
You can probably do that in your UITableViewControllers -viewDidLoad method.
self.tableView.style = UITableViewStyleGrouped;
Edit:
It seems the style property is actually read only, so the above won't work.
It looks like the table view controller has to be created with -initWithStyle:, but I don't know how to do that from Interface Builder. I'm not at my Mac right now, but will have a look later.
Edit 2:
Here's what I did in Interface Builder:
Add an instance of UITableView and set it up as required, including the style
Hook up your UITableViewController as the delegate and data source of the UITableView
Connect the UITableView with the view outlet of the UITableViewController. I'm not sure if there is a tableView outlet - if there is, then probably connect it with that one instead.
So, basically, instead of letting the UITableViewController create its own table view, you provide one in the xib and set up the required connections (delegate, data source, outlet) manually.

I already have a view controller, is it possible to attach a table view on top of the current view, without the needed to create a subclass of UITableViewController?
Thanks
Yes, just set up the table view like any other view and connect it to your viewcontroller by setting the delegate (reference) and dataSource (reference) - properties. See the references on which method you have to implement in your viewcontroller in order to get things working.
Sorry but I found no clear answer on that.
I have an iphone app with a tab bar and a UINavigationController in each tab.
The interface is built with Interface Builder, and in the first tab there is a UITableView.
I have prepared the xib with main view (A) containing a table (T) and an image (IMG) background behind (image as subview of main view).
Later I assigned UITableViewController as owner. This is where problems start.
In IB if I connect view to A I got a runtime error telling me that controller cannot find a table.
If I connect controller view to T everything works fine, except that IMG is not shown.
The only solution I found is to create a new xib holding A and IMG with a UIViewController as owner. Then create a xib holding T only and UITableViewController as owner, correctly connected to T.
Then in viewDidLoad of the UIViewController:
iptc = [[IPPlantsTableViewController alloc] initWithNibName:#"IPPlantsView" bundle:[NSBundle mainBundle]];
iptc.navigator=self.navigationController; // <-- need this
[self.view addSubview:iptc.view];
And this works, except that the table view seems to not know anything about navigationController, therefore detail view mechanism is not working, unless I set a property for it in UITableViewController.
I also run in to some other problems, for example all the logic for adding/deleting/creating rows to table has to be handled in UIViewController and sent to UITableViewController.
Is there another way for having a fixed image in a table view ?
Mmmm
I will be honest i HATE Interface Builder ;-) so I can't help you about this.
But to set a fixed image in the background of a UITableView you should :
- set background color of the UITableView to [ UIColor clearColor ] (and maybe the background of the cell too)
- set and uiimageview below the uitableview view that contains the image :)
In that way this should work.
But without xcode project I can't help you more ^^
Good luck
UITableViewController is a convenience class; you can equally just use UIViewController and implement the correct callbacks.
In OS 3.2+, you can just set UITableView.backgroundView. If IB doesn't let you do this, you can do it in code instead.
Alternatively, you might be able to wire up the view and tableView outlets differently, unless tableView just does (UITableView*)self.view.
I have a tab bar application. In one of my tabs, there is a search bar and a table view below that. When you enter something into the search bar, it returns parsed xml. I need to put this parsed information into the tableview below. The class inherits from UIViewController. I declared a UITableView object in the header file and linked it in interface builder, and adopted the UITableViewDelegate protocol.
I'm not sure If i'm going about this the correct way. Any help?
That sounds about right. You will need to also have your UIViewController implement UITableViewDataSource, and add the methods from that protocol to populate the table.
There are various tutorials available which guide you step-by-step to create a simple tablview. Google them. You can follow these steps for connecting your tableView outlets:
Select your viewController where you are displaying the tableview to be your "File's Owner" in Identity Inspector.
Drag your view's outlet to your File's owner.
For tableView inside view, drag its outlets to File's owner again so that your datasource and delegates are up. And in the same view, drag your referencing outlet to the IBOutlet you have created in your viewController class.
I'm having trouble creating a UIView (in Interface Builder) that contains a UITableView with some other object, such as a UIButton or UILabel. The UITableView always takes up the maximum amount of space in the UIView, regardless of the size of the UITableView object itself. The File Owner is a standard UITableViewController.
Here's how to do this easily:
1) Create a table view controller with xib.
2) Change the inherited type in the .h file from UITableViewController, to UIViewController.
3) Add the protocols UITableViewDataSource, UITableViewDelegate to the .h file.
4) Open the xib, add in a view.
5) drag the table view in the xib under the view, resize as desired.
6) Wire the "view" property of the File's Owner to the View instead of the UITableView. The datasource and delegate properties of the table view should still be wired to File's Owner.
7) (optional) if you want to be able to reload or otherwise access the table outside of table view controller delegate methods that pass in a table view, make a UITableView * IBOutlet named "myTable" or the like, and wire the table in IB to that.
An alternate approach is to make a new UIViewController with xib, add a table to the xib, wire datasource/delegate to the file's owner, and make a new UITableViewController class which you use to copy the methods from into your view controller, then delete.
Unfortunately, creating a UITableView in Interface Builder (IB) is was very problematic for me. I ran into the same problems as you as a beginning developer and, after much frustration, just ended up abandoning IB for UITableViews.
The best solution for me was to just implement the UITableViewController (and the UINavigationController that you use as a header) programmatically. Once you figure out the whole Model-View-Controller paradigm, it is actually fairly straightforward.
Some good resources for dealing with them programmatically can be found in Apple's documentation with these names:
"Table View Programming Guide for iPhone OS"
"View Controller Programming Guide for iPhone OS"
Cocoa with love has an article about Recreating UITableViewController to increase code reuse. This is useful if you can't use a UITableViewController, but want to make sure that your UIViewController will behave the same way.
In an iPhone navigation based app, I want to add a second tableview but have its design available in IB. I've added a new empty XIB and dragged a UITableView onto it. I want to setup the layout through IB. I've created a controller for this tableview and set the File's Owner class in IB to this controller. I linked the tableview to File's Owner as well. I set the tableview to grouped in IB. However, that does not translate at runtime. I still have a plain tableview. In fact, none of the Inspector settings work at runtime. What have I missed?
Make sure when you instantiate the view controller you do so using initWithNibName:bundle: using the name of the file you've created.
UITableView *myTableView = [[[UITableView alloc] initWithFrame:CGRectMake(0,80,320,480) style:UITableViewStyleGrouped];
Select your tableview and open it's inspector. In the first tab of the inspector, expand the "TableView" and you should see an option called Style. Change it from "Plain" to "Grouped".
If you can't find this, try this on your viewdidload
tableView.style = UITableViewStyleGrouped
