How can I add a UITabBarButton with a button that triggers a modal view, rather than just showing one of the tab bar view controller's views? RedLaser accomplishes this. Notice the red "scan" button below. Also, how can I substitute one of the tab bar items with my own image without just slapping an image view over it? The image needs to span the whole area of the bar item.
Instagram also does this with the "Share" button:
Just realized my oversight--simply create a new background image for the tab bar and load that in. On that image, contain any other images that need to go over an entire tab bar item.

I am working on a tab bar application. Is there a way I can programmatically hide one view controller from the scroll down list and from the "edit" list (but still be able to pop it on screen with a certain action, i.e. by calling its tabbarcontroller index)?
The problem is that I have now so many viewcontrollers that completely fill the "edit" screen. So I want to hide some of them and be able to trigger the hidden ones trough some action performed on one of the visible ones.
Thanks
I have a tab bar controller and some nav controllers containing view controllers. In those view controllers I want to be able to have a timed banner that will animate up from the bottom of the view.
I started making a subclass of UIViewController with the images, but when I add it to my viewControlers it renders anything beneath it not clickable.
What is the best way of achieving this ad pop up and have it be reusable in all my viewControllers?
Make sure the main view of this ad popup is not of zero width or height - banners from many ad networks will actually be displayed if you add them to such a view, but won't be clickable.
Also make sure the ad view is in front (bringSubviewToFront:) and, if you have a tab bar, try adding it to the main app's window, rather then to the current view. Tab bar can play tricks with Action Sheets (basically some buttons will be unclickable) which are solved by adding the Action Sheet to the main window. This may help with your popup ad views, too.
I have a navigation bar in my app. The below pictures are in the order of navigation.
Problem I have is, on clicking the "Main" button , I am able to perform the action and goto the required screen , but the navigation bar does not look like the first on (with Menu as left button). Instead it look like 4th image. How to make it look like first image so that I can make the user to navigate to "Menu" screen by clicking menu button ?. Thanks for the help …!!!
If I'm understanding this correctly, you may have pushed the first view controller (The one from screenshot 1) when clicking on main which is why you see "lens" in the back button. That back button takes the title of the previous view controller in the stack. What you want to do is pop to the first view controller when they click on Main using either popToRootViewController or popToViewController:animated
I have a UISearchBar which is subviewed by another view when a button is pressed. When it loads, it looks like the following (minus the red scribbles):
I would like to have the UISearchBar view be removed from the parent view controller when the tableView (the area with red scribbles) is clicked and is empty (no search has been made yet). I'm having a difficult time figuring out the best way to do this.
I have tried to put a transparent button in that section and add it as a subview to the search bar. However the button is underneath the tabl view area, so when the table view is clicked, the search bar loses focus and the uibutton is only then accessible.
Does anyone know how I can remove the search bar from the parent view controller when the empty table view below it is clicked?
Thanks.
To bring the transparent button up and make it catch all touched first, use [button.parentView bringSubViewToFront:button].
Another approach could be to catch the search bar losing focus (since you say you see that happening), by putting
– (void)searchBarTextDidEndEditing:(UISearchBar*)searchBar
in the search bar delegate, and handling it from there.
When in the Camera Roll section of the Photos app, you can click the top right button to edit the photos. This replaces the bottom tab bar with three new buttons.
I would like to do something similar, but I cannot get my buttons to be on TOP of the tab bar. Is there a way to specify the layer order? Or do I need to do something different?
I would add a new UIView. I would add it to the view your tab bar is in (like, let's say UIWindow). From there you can use -bringViewToFront (or something similar). That way you will have control over what is in front of the UITabBarController's view.
