I'm trying to follow this tutorial here to recreate a custom center tab button, but I already have my tabbarcontroller setup in IB. Can anyone help me do this? The tutorial does it all through code so its difficult to follow.

All they're doing is creating a blank UITabBarItem, no image or name, simply a placeholder. They then put a UIButton with a custom image (i.e. the green camera button) on top of the UITabBar. Just go into interface builder and add a new TabBarItem and put a UIButton on top of it.

I would like to set navBar buttons like safari as following image shows. However I can only set a custom image for toolbar button but square button container remains although I set plain style. How to reach it? Thank you
Plain is only for tool bars not nav bars, that's the only way you can achieve no border. You must use a custom UIButton on your navbar to achieve the same results.
If you need an icon somewhat like that, you can check on Default Icon
Use UIBarButtonItem method for creating bar button
- (id)initWithCustomView:(UIView *)customView;
and create custom view with UIButton of type UIButtonTypeCustom
I'm trying to create a 'Refresh' button containing the standard UIBarButton refresh system glyph, which, when tapped, will animate a custom view, then fire another selector to call the intended refresh action.
I know I could do this with images and two inner views added to a custom view, but is there any way to do it with the standard glyphs from UIBarButtonItem? Are they available at all for UIButtons?
When I was creating my iOS application, I wasn't able to find a "refresh" button for the UIBarButtonItem. I had to take a Rounded Rect Button and place it in the top right hand corner and create a custom image to overlay onto it.
Edit: You can find it in IB. When you add the UIBarButtonItem, select it and then select the attributes inspector tab. Click the Identifier drop down and within that there is a selection to change the button to look like the system refresh button.
I added a UIToolBar from Interface builder, then dragged 2 UIBarButtonItem's. Now i need to add an image to it. So i selected the barButtonItem and selected the image using Interfacebuilder.
I only get a White image, with no curvy edge. My image is as follows. I don't see that image, but instead i see a white rectangle.
How do i prevent this. Can someone tell me whats wrong, and provide me with a working solution.

If you go to iOS Human Interface Guidelines you will see the specifications for icons and buttons. This is my experience, for the best result you'd better create a specific icon (image) for UIBarButtonItem. If you still want to use an image, that doesn't follow the UIBarButtonItem guide, my approach is:
Add a generic UIButton instance to your view. Drag it from the list on the right to the view, not to the ToolBar or navBar.
Customize it with the image, i.e. from the Inspector, set the image or background image, or set it to custom style, bordered, etc.
Drag it to the toolBar, and XCode will adjust it. Again, it does not always guarantee the best result, but it does what you want.
I hope it helps.
You should drag an "Image View" on to your layout and specify the image in that - that worked for me, but I'm no xcode guru.
Hope that helps, Paul
I have a requirement to pop up a small option-view on clicking bar button item, similar to this image.
How can I achieve this? Any tutorial or link is highly appreciated.
I'm not sure this is available on iPhone but I know that on iPad UIPopoverController it looks so.

You can find source code here to create PopoverController on iPhone !
You need to create an UIView and set for backgound you image. In this new view you can add UIButtons to let the user to select an option.
I need to create a UIToolbar object that uses an image for the background. Most of the buttons are images as well, and rectangular. One button, however, is round and overlaps the toolbar like the Start button on the Windows task bar. See below.
I know that I will need to subclass the UIToolbar to paint the image for the toolbar -- I think. If so, does anyone have example code showing how to do this?
Furthermore, does anyone have any ideas on how to implement the larger round button? I'm thinking of another custom subclass for this, but not sure if there might be an easier way.
I can have the art guys chop the image anyway needed, which I'm sure the round button will need to be chopped some how.
Any ideas or sample code?

Maybe you'll find some inspiration at this tutorial : Recreating The Raised Center Tab Bar Button of Instagram, DailyBooth & Path
For the color, you can experiment with the tintColor property.
As for the rest, UIToolbar is not designed for this. You will need a custom component (probably based on UIView).
I think it is possible but hard.
Override the drawRect method of the toolbar to draw the whole image. Then add left and right buttons.
For the round button you can add one invisible button on the bottom middle of the View and another invisible button in the middle of toolbar. Of course, you can try to use the views instead of the buttons and track the user interaction manually.
