I am working on app where I have some list of content shown with some buttons . I need a dock kind of animation when I touches the button , then clicking on the docked button event should be fired. when I touches another button this one should be docked . I have seen the following like

but , here I need to create a separate view for handling this . But I need this only for some of the buttons only , not for the entire view.
Any suggestions ?
Thanks in advance.
I didn't check in details the code you linked, but actually a UIButton is a UIView. You may consider subclassing UIButton and implement those methods. This way, animating the whole view means animating the button.

I have seen many examples of the raised center button on a UITabBar, most being just a UIButton placed over the top but all of these need coding on every view, Is there a way of creating this without having to program every view so it will appear on every screen, perhaps something in the app delegate?
I want to achieve a UITabBar with a raised circle in the center.
Subclass UITabBarController. I've found an example here: Raised Center Tab Bar Button.
I am trying to make an app where I have a UICollectionView of UIButtons, and I want to take another UIButton from the bottom of my screen, drag it in between any other two buttons, and have them separate to make room for the new button in case the user wants to drop it in there. So far, I have been able to make my button dragable using UIPanGestureRecognizer, but haven't gone much further than that. Any suggestions or help would really be appreciated.
Is it possible to present my modal view controller with the keyboard already visible? Currently, the modal's text view becomes the first responder as soon as it's view is loaded, which causes the keyboard to animate coming up from the bottom.
I'd like the keyboard to already be on the modal and be a part of it's transition. Any suggestions?
The keyboard is a separate UIWindow object. It is not in the same view hierarchy as your view controller's view. To make this happen, you would have to dig around in the UIApplication's windows property for the keyboard window and replace its default animation with a custom animation.
You could try putting the becomeFirstResponder code in vieWillAppear, but that isn't the "right" thing to do anyway.
You will probably need to replace the actual keyboard animation with a custom animation to force it to load immediately and without scrolling up.
At the moment I'm working on an iPad explore game which has a hexagon tile map.
I've created a UIScrollView that contains a background view (the game map) and buttons in the form of hexagons (for interaction). I add every UIButton to the view via addSubview.
But... when I add more than 100 buttons the view gets laggy (no surprise here). But what should I do to solve this?
Example:

Adding UIButtons isn't the way to go here. You should probably draw the "buttons" in a custom -drawRect: method and use -touchesEnded:withEvent: to decide what the user wanted to do.
I'm working with Xcode doing a Ipad app.
i simply want user to click anywhere on screen (not counting text fields) to perform some IBAction.I'm using an invisible button that covers my whole view.
Since I have some text fields in my view,i need to add this invisible button to the background of my user interface. I cant seem to find this option in the button attributes? any help?
Just set the button's type to custom.
Did you try setting the opacity of the button to zero?
I guess i got your point. You just want to put the UIButton(invisible) on the back of all the UITextField. The simple solution to this is open the Document Window in the IB. Now expand the view tree in the list view. Just drag your UIButton above the UITextFields and set the alpha value for the button in the property to be zero.
Hope this helps!!
iPad users don't "click". They "tap" or "touch".
In Interface Builder, I believe views are constructed with a z-index from top to bottom as they appear in the document window, so dragging your button so that it appears as the first subview of your main view should be a quick fix for this.
Have you considered other approaches? This doesn't sound like standard behaviour for an app and will probably cause havoc with anybody using Voice Over. What are you trying to accomplish?
