I have a PullRefreshTableView from leah(https://github.com/leah/PullToRefresh). Problem with this, as soon as I implement this. The view is changed to a tableview by doing this:
#interface news : PullRefreshTableViewController {
So I can't add any toolbars or navigationcontrollers to the top. Does someone know how I can add a toolbar to the top of the screen in combination with the PullRefreshTableView.
Thnx!
You know when you have this standard UINavigation template when you create a new project with xcode? Gives you 3 ( right ? ) nib files, 1 with the window, 1 with the mainview / navigation controller and the other one contains the tableview.
Open the one with the tableview. Select the tab that looks like this:
It will allow you to change the class it creates when the nib file is loaded. Change it to the PullRefreshTableView and when you launch the application a PullRefreshTableView will be created instead of a normal table view.
You can hook this up as an Interface Builder outlet exactly the same way you would hook up a normal table view. Its a subclass so it should even be able to be connected to the normal tableviewcontroller that is included in the template.
If you have done this, you should still be able to add the toolbars like you did with a normal table view. Also, if you want to have a toolbar on your iphone screen it shouldn't be a subview of the Tableview, but a container view should contain both the toolbar and the tableview.

I have 4 different viewcontroller and these are connect with 4 tabs in UITabBar. I have to write respected code in each viewcontroller but I noticed the code which is written in each viewcontroller is not loading. Where to write code in each viewcontroller when it is loaded after selecting tabs in uitabbar?
You need to create a view controller file for each view (simply right click on the left where the files are and do New File -> UiViewController).
After that, in the Storyboard, select the view, and in the properties, change from the default view controller to the custom one you have created (this is the third icon on the right panel, under "Custom Class"). The UITabBar should handle switching the views, and your code will make the views run uniquely :)
I have a UITableView has a subview of a UIView and I've added a toolbar on top of the UITableView so it should look like this:
However when I actually run it, it looks like this:
So for some reason the UIToolBar isn't showing up. I really don't know why, is anybody able to figure this one out? Thanks in advance.
EDIT: I've changed the simulated metrics like suggested and it still does not show up:
EDIT2: Here is a list of objects as requested by Raixer.
Alright. I have a similar setup in my app so I will show you what I did.
I setup a tab bar controller with navigation controllers in each tab (this gives me the navigation bar automatically that is why I use it). If you notice the View on the first tab is being loaded from another nib (that is what I am assuming you are doing). I did this by changing the view's class to my own view controller and then setting the name of the NIB file to load in the Inspector like this:
(source: minus.com)
Then in my other nib file I only have this:
I hope this helps.
That's because you configured your nib file without counting with the height of the Tab bar.
The toolbar's height is 49 pixels. So when the view appears all your elements are moved 49 pixels up.
You should got to IB, open your View, go to Attributes Inspector, and in simulated metrics select Tab bar for Bottom Bar.
I doubt you will succeed with this approch. UITableViewController is very picky about adding subviews to its UITableView. However, you can have your UITableView handled by a standard UIViewController (just let IB point to a custom class inheritng from UIViewController). Add the table view to the controller's view as a subview and add the toolbar to the outer view.
Then you should be able to add subviews. UITableViewController gives you some convinience and functionality. If you can live without, UIViewController is no disadvantage. If you can't, you'll have to implement it yourself.
Another alternative to get the toolbar: put your table into a UINavigationController. That one comes with a toolbar (on top).
I've been looking everywhere but can't seem to find any examples/tutorials for my situation (not sure how to google it..)
So i have a window where a portion of it should be static (buttons and such) and there is a dynamic part (bottom leftish) that should change subviews.
So what i'm looking for is a way so that clicking the buttons in the static area will change the dynamic area to a view of my choice. I have no idea how to do this using the IB, but doing it programatically seems the only way. Any suggestions(I do not want to use a tab bar controller)?
Oh, and is there a benefit to making views and such programatically vs through the IB?
Thanks!
You can also achieve it programatically. Just create another viewcontroller class (as many as u want). In the loadView method of it create a UIView in the coordinates where u want to add the subview in the current view. Now create an instance of this viewcontroller class in the currentview controller and add it as a subview. You will get the subview at the desired location.If u want to change it dynamically create as many views and then add them to the array and change them whenever the button is clicked.
Hope this helps.
You should perform the switch in your view controller. The static buttons can have their actions hooked up to that controller (in IB), which can have an outlet (in IB) to the subviews and perform the swap.
As for when you should use IB, see this question.
You can do it from interface builder as well. You just need to take viewController from interface builder drag-n-drop to main window. assign IBAction to all buttons to add different viewController's view to main window just make their frame some smaller.
if u want to change or views by click on button then u chose segmentcontrol switch. and cod for each segment like as when click on segment 0 then open first sub view and when click on segment1 then open second sub view. And make by default unselected so that ur static view will appear initially lunching of view.
All,
I found the code in Matt Gallagher site ( http://cocoawithlove.com/2009/04/easy-custom-uitableview-drawing.html ) for this really neat design for a Table View... Im very new to Cocoa and Im having a hard time figuring out how to wire the darn thing in IB...
I loved the design and wanted to use something similar in a more complex structure... Nav Bar / Tab Bar with a few other views / TableView for the data in the first view... I found lots of tutorials to do that and got it working... When I tried to use that design in my project, things went crazy... in My MainWindow.xib I cant have a UIView where the arrow is pointing...
the nib looks like this:
Tab Bar Controller
Tab Bar
Nav Controller
Navigation Bar
Table View Controller
Table View
---->>>> (UIView for the backgroundImage )
Navigation Item
Tab Bar Item
UIView Controller
Tab Bar item
Window
can anyone guide me in the right direction??
Thanks !!!
It sounds like you're not having issues with the table view as much as the construction of the hierarchy around the table.
Instructions for creating the hierarchy would be as follows. I think you've diverged at around step 9:
Start with new copy of the default iPhone "View" template
Throw away the view controller class.
Open the MainWindow.xib and delete the view controller there too.
Find the controllers in the
Interface Builder library palette (they're
the yellow spheres at the top of the "Cocoa Touch" library in "Objects" mode whose icons contain
other objects).
Drag the tab view controller into
your MainWindow.xib file at the top
level.
Expand the tab view (triangle next to its name in the list view of the xib)
Drag a navigation controller into your expanded tab view (if this works, it should appear as one of the tabs along with the two view controllers that are there by default)
Expand the navigation controller
Drag a view controller (not a table view controller) into the navigation controller. It should appear as the content of the navigation controller.
Select the view controller (single click).
Press Command-4 (or select "Identity Inspector" from the "Tools" menu).
In the "Class Identity" popup menu, select EasyCustomTableController (this assumes that the current xib file is part of an Xcode project and this Xcode project already has EasyCustomTableController added to it).
Add a UIImageView to the view controller's view (this is your background image)
Add a UITableView to the view controller's view (this is your table). Add this view so it is after (and hence on top of) your image view.
There should be a tableView outlet on the view controller. Connect this to the table view.
Connect the app delegate's viewController to the tab bar controller (back in Xcode you can optionally change the type of this property to UITabViewController)
Should work.
The trick is that UITableViewController can't be used if you want the view to contain more than just a table. For this reason, you must use UIViewController and recreate the functionality that the UITableViewController adds. See here for how this is done:

Thank you Matt (kind of cool that you answered)!!
I really appreciate the help... I've been messing around with it and got it to work using a UIViewController in another view (being created from the tableview)... Once I had the UITableViewController in the navigation I dropped the imageview & used a gray color; it looks great!! The initial screen has the rows big enough that scrolling is not an issue... I will go back and try to change that now...
I do have to say that IB is by far the most challenging step in app development for a newbie coming into Cocoa Touch !!! Yikes!
i have attached as header one UIView(which has lot of buttons etc) in UITableViewController.i did not use table header.but when i scroll table view ,the header view (XIB file) goes upwards..can i stop it?
Don't create it inside the UITableViewController. Create it outside and then you should get the desired behavior.
