What is the best way to have the right navigation bar button flip like it does in the ipod when one changes from list view to single song view? Subclass a custom view? Are there any api's out there that already do this?
thanks
This question is similar, and discusses a few solutions. The main issue is that the UIBarButtonItem isn't a UIView, so you can't use the UIView transitions. iPhone flip right button (like iTunes)

Thanks for reading my question!
I have a 5-part tabbar which I use for app navigation, the center tab is covered by a UIButton and is slightly larger (much like the instagram app). This works fine.
But what I want is the far right tab bar item to show a overlaying menu when clicked. I don't want it to switch to a viewcontroller with a menu. I want the menu to be displayed no matter which of the other views you're in at the moment. So I want it to act much like a button which is in the tabbar. But I have no idea how to go about doing this.
Should I use a overlaying button over the tabbaritem or should I catch the tabbarclick, but how can I prevent the view from changing in that case?
Thanks you for any help!
You need to implement UITabBarDelegate. Then override tabBar:didSelectItem: and implement your custom displaying here. See below for reference
http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UITabBarDelegate_Protocol/Reference/Reference.html
Then i would just make a custom UIView and fade it in when that specific tagged UITabBarItem is pressed.
I am currently developing as app for iPad. And I need to create a tabbar. The problem is that, for design purposes, I need the tabbar to be on the top half of the screen and not on the bottom as it is on the default tabbar controller.
Once the tabbar is on top I want that when a button is touched, the subview bellow the tab is changed. Furthermore, the subview that should be loaded was alson designed inside the storyboard. The following sketch shows what I want it to look like:
On my research I found a solution (here) for putting the tabbar on top. Now my problem is on loading a subview bellow it.
I tried it with [self.view addsubview:theNameOfTheViewCreatedINStoryboad.view] but the application simply hangs when I press the button.
I think that is because I am not specifying anywhere what should be the dimension of the new view or where on the scree should it be placed. The reason for that is because I do not know where it should be done.
Can anyone give me some lights on this matter? Is the referred approach the best one for putting a tabbar on top? How can I solve the subview problem?
Glad to see you are using a toolBar and not a tabBar. Even better would be to create a custom content view controller.
You should be looking into using containment:
UIViewController containment
How does View Controller Containment work in iOS 5?
positioning UIViewController containment children
check out the docs
Could anyone provide some guidance on how to implement that speech-bubble like popup menu when you click "More" in the IPhone IPod application toolbar?
I think you are looking for UIPopoverController. Popover controllers are just containers for view controllers: write a view controller that does what you want, and you're set. But this is for iPad. If you want this for iPhone, then read on. I have put up some solutions.
You could even explore UIActionSheet but UIPopOverController gives more flexibility.
I believe you are talking about something like this ?
Here are some solutions you could adopt -
Forgot that you wanted this for iPhone, Have a look at the iPhone UIPopoverController implementation: WEPopover
On iPhone you would generally use a UIActionSheet for a stack of buttons like that. It slides up from the bottom, rather than popping up next to the button, but that's the standard behavior on iPhone.
Or you could manually instantiate a UIView using a custom background image or drawing with transparency, add some UIButtons (or other type of custom view) on top, and also somehow handle all touches outside that view.
Note that is is non-standard UI. An actionsheet would be more HIG compliant.
I have an iPad application with screen flows which don't map neatly to the navigation controller model, but still have the concept of "Back".
I'd like to manage my own toolbar and have a "Back" button where I decide where it goes.
Is there a way to make a toolbar button have the look of a back button as in UINavigationBarItem?
Thanks
Basically, you either have to use undocumented APIs, or create a custom button with a custom image.
This question:
Creating a left-arrow button (like UINavigationBar's "back" style) on a UIToolbar
has answers that cover both ways.
(Placing a UINavigationBar back button look alike icon somewhere other than the left of what looks like a UINavigationBar is probably against the HIG and may result in non-approval of the application, though perhaps only if you're unlucky.)
My customer wants a design-change, but I just can't figure out how to do this!
The app currently have a UITabBarController shifting between some UINavigationController's. My customer wants to use a UIToolBar with a UISegmentedControl shifting between the controllers instead.
I want to keep the UITabBarController, because that takes care of everything regarding loading and shifting views, but I want the UIToolBar to act as the UITabBar instead of the UITabBar!
I have allready figured out that I will need a custom UITabBarController and possibly a custom UIToolBar as well.
But I have absolutely no idea of where to start, so it would be great if somebody could give me a pointer as to where to start.

Thank you.
If I understand your requirements correctly, you want to have a UIToolbar at the bottom of the screen that has a UISegmentedControl that replaces pressing UITabBarItem's to switch between different views and view controllers? Assuming this is true I'd start with a custom UIToolbar class, say SegmentedControlToolbar that mirrors the basic behaviour of UITabBarController and UITabBar to add items to a segmented control, attach view controllers to each segment, and finally handle presses for each segmented control change to actually switch views.
