I tried working on tab bars on top of the view controller ,we can do default tab bars by using xcode storyboard .but i need to build custom tab bars on top of my screen in ios app by using swift 2.0.
You cannot change the UITabBar position

On a brand new MACOS application project (swift, storyboards), using the latest available version of xCode (8.3) I can't get a crossfade transition with a NSTabViewController that I add to my story board. The window is not resizing as well.
What am I doing wrong ?
I start by adding a new window controller, I remove its content view controller that I replace by a tabviewcontroller.
The tabview controller comes with two tabs wired to two view controllers. I resize one of them to make it bigger and put random buttons on both of them to be able to check wether the full view is visible or not at runtime.
Everything is left with default settings, as well as the "crossfade" transition of the tabviewcontroller.
But when running the application, tabs change abruptly, and the window doesn't resize to display the new tab.
My goal is to build a preference panel on my storyboard ans I just fail on the first steps.
For crossfade animation to work, you need to connect delegate outlet of the tab view to the tab view controller.
It does not seem smooth resize is supported by the standard tab view, though.
I have a tab bar controller with a logginViewController, and I want to hide the tab bar item related to logginViewController and show a different tab bar item with a different ViewController
I'm working using Storyboard in a tab bar based app for iPhone
I've tried this solution but it doesn't work (Xcode don't allow me to use the "hide" option)
Please, any help on how I can do it in Xcode 4 will be great!
Thank you all
I like to suppose, that you subclass your TabBarController.
Via Protocol/Delegate you're able to work with data from your loggingViewController (maybe, a button get's clicked to hide the TabBarItem).
Implement that protocol to your TabBarController and so you're able to receive those protocol-methods to add/hide/delete the Items easily.
Try it out! Or further questions?
I am working on customizing my tabbar background image and i resolved this for iphone by customizing tabbar class. it looks like that:
Then same thing i put for my ipad app it looks like that
I need the tab bar without extra spaces or black color in the image above. so i tried to update the tabbar class for ipad as well and i reached to this image below:
I managed the tabbar button views without extra spaces but unable to manage its button selection area, how can i manage the tabbar button selection ? it is still the same as second image, you can see the highlight of "settings" tabbar button selection in "Transaction" tabbar button.
The UITabBarController cannot work as you would like it to. You should write your own UITabBarController class - see this for an example of how: https://github.com/aalittle/ALCustomTabBarController
I've designed my iPhone app in Photoshop and now I have all the PNG files of my project.
I have Xcode 4.2 and iOS 5. What I would like to do is to customize the tab bar of my app. I've done the things on storyboard, but I do not know how to implement the PNG tab bar in the storyboard. I've written the source code of the customized tab bar, but when I run it in the simulator it doesn't display the ViewController which IS already done on the StoryBord.
So, the question is: how to attach the new tab bar design with Xcode Storyboard?
If you've subclassed the UITabBar and written code to customize it, you'll need to set the tab bar's class to your subclass in the identity inspector. Click the tab bar in your storyboard and set it's class:
Then it should begin using your custom code.
I try to place UITabbar on iPhone window using CGRectMake.
But I found that the Y position is different from the display in Interface Builder.
Is there anyone met the same problem?
Using CGRectMake to locate the x,y position, is it possible cause the refusing from App stoe due to compatible reason?
Thanks

If your tab bar is associated with a tab bar controller it may not be moved in code. From Apple's documentation:
"Important: In iPhone OS 3.0 and later, you should not attempt to use the methods and properties of this class to modify the tab bar when it is associated with a tab bar controller object. Modifying the tab bar in this way results in the throwing of an exception. Instead, any modifications to the tab bar or its items should occur through the tab bar controller interface. You may still directly modify a tab bar object that is not associated with a tab bar controller."
