I want to implement the side swiping gesture to go from one objet to another. Just trying to figure out what its called so I can start looking up some tutorials.
Add your view controllers to UIScrollView and set the pagingEnabled property of the scroll view to YES.
The small dots displyed at the bottom of the iPhone's home screen is UIPageControl. You need to configure it to fit your needs.
You can use a UIScrollView to implement paging.

I am working on an app for iOS and I have to do a tab selection screen like the Google Chrome app for iPhone (I attached a screenshot). I searched a lot but I didn't found any similar control to use. As i can see, it groups some UIViews and use a UIScrollView to scroll, but maybe any of you could explain me better how this control works or have any solution.
Thank you!

Create Different UIViews with your controls.(One tab is equal to is on UIView)
Add this UIView's on UIScroll View.(This is optional. It's ok if you don't use the UIScrollView and add UIView on self.view
Implement the touch method on UIView.
When you get a particular UIView is touched change it's center position to Center of the screen.
Which will give you the UIView which is touched in foreground and rest of the Views in background.
Hope this will help you .........
I solved my problem with this ......

I've seen iOS apps that allow users to scroll around a view that is larger than the screen itself, without seeming to implement a UIScrollView mechanic. So for example, the actual image displayed on the screen is double the width of the screen, and the user can pan left and right to view all the content. Is this just a case of making the ViewController's width twice that of the screen and allowing some kind of panning via gesture recognizers? With what I'm trying to do, it seems like this would be easier that implementing a UIScrollView...
Implementing scrollview is much easier than handling pan gesture, when Apple has given built-in functionality then why you do not want to use it?
You can either use UIPangestureRecognizer or UIscrollview. The Latter option is very simple.
I want to implement a scroll view which looks like the stock ticker. It can respond slide or tap gesture.
How can I implement this? Please advise me. Thank you!
Use a NSTimer to reposition the contentOffset of your Scrollview.
Use the UIScrollViewDelegate to stop your animation while the user is dragging the scrollview.
Conceptually I'd setup an container UIScrollView with the contents of the scrolling area as subviews. To simulate a circular scroll I'd keep an array of the subviews. I'd add a view just off screen at the starting edge, and take away a view just off screen at ending edge.
UIScrollViewDelegate methods will be called when a person starts or stops dragging the view, which you can use to start and stop the animated scrolling. Other methods in this protocol can be used to reset the contents of the scrollview when the edge is reached, so more views can be added as needed.
I'd probably use a CADisplayLink to manually manage the animations. The method given to the CADisplayLink would update the scroll and manage adding and subtracting views to the edges. It would also stop scrolling based on a flag set by the UIScrollViewDelegate methods when the person is dragging the scroll.
Unless you jailbreak, you can't put custom views in Notification Centre.
I am building an Iphone app.
I need to display a settings Menu to the user when a button is clicked. The menu will NOT be covering the whole screen and there is a specific location I want it to appear. How should I do that?
I understand how to set the hidden property of a subview to give the illusion that the subview is not onScreen. However, I need a view controller for this subview ( meaning .m and .h files as well). So How can I add this subview programmatically at a specific location.
Thank you very much
What you are describing is very much the behavior of a UIPopoverController. Unfortunately, that is only available for use on iPad's and not iPhone's or iPod Touches. So if you want to develop this you will need to develop this from scratch.
It's not a UI pattern you see much on the iPhone due to the screen size, but I imagine you will need to build up a custom UIView and add it the main window view with a specific size (smaller than screen size) and with the view's frame.origin set to a value other than (0,0).
Just make sure that what you are trying to achieve falls within Apple's Human Interface Guidelines.
[myView addSubview:myViewController.view];
myViewController.view.frame=...
In my app, I have part of a view sticking out from the right. I would like the user to be able to swipe that to the left, to pull/reveal the rest of that view, which would basically almost cover the screen. See below:
I am figuring my best option is to use UIScrollView for two reasons. That I can lock the movement to horizontal only, and the animation for swiping is already built it.
My question is, can I have one page of the UIScrollView smaller than the other as shown in my mockup images?
UIScrollView horizontal paging like Mobile Safari tabs
