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 can do this programmatically but I don't prefer it that way. There's got to be some work-around for this. This is what my initial screen looks like:
To the toolbar, I dragged on a Bar Button Item and it fell into its proper place. Then i need a Text Field beside that. I dragged that from the library and dropped it beside the Bar Button item, and this is what I get:
What am I missing here?
My problem is thus: I've created a custom view, a numeric keypad, that I display when a button is pressed. When anywhere else on the screen is tapped, I want to hide the keypad.
I solved the problem by overriding touchesBegan:withEvent. Then a hit test tells me if the numeric keypad was pressed. As long as the keypad wasn't pressed, I hide it (by setting its hidden property to YES).
It works, but I don't like it. Its not very clean. My other option is to have a view controller for the numeric keypad and display it as a modal view controller. The keypad view would have a transparent background. I don't like this method either.
Any ideas?
A simple solution would be to have an invisible UIButton that you add to the view when the keypad comes up and remove along with the keypad when it is tapped.
Of course, the tap you get on the UIButton will prevent you from using that tap for anything else, so your interface wouldn't work while the keypad is there.

Save user selection somewhere and before you show your picker view set its selection programmatically with selectRow:inComponent:animated: method:
// Create picker if needed
[pickerView selectRow:13 inComponent:0 animated:NO];
// Now show the picker
