I have been searching for a way to do the following:
http://a5.mzstatic.com/us/r1000/014/Purple/9c/af/dc/mzl.hdgiidhq.320x480-75.jpg
I want to have a view but be able to slide through them so they show up one by one..
each view pulls up new data from my plist.
I am not sure what this method is called to properly research it.
could someone please point me in the right direction?
Check out the sample code for Page Control. It shows the basics of a paging scroll view with different subviews on each page.
One of the important concepts is reusing the subviews, which you'll find out about in the sample code.
I think you need a scroll view with paging. User can view its subviews by swiping.
This is not an innovative functionality. It is the default functionality of scrollview.
Hope this helps ...

I have a simple problem but I can't figure it out. I have a UIScrollView with three nested UIWebViews. I need to be able to "recycle" these views to actually scroll through lots of content.
My main problem is that I can't figure out how to show a view that isn't the very first, meaning that you can immediately swipe back from. Right now I have three views paging, but it starts at the first one, and you can move right two.
What can I do to make it so that I am always in the middle? With the ability to always swipe right OR left?
Thanks!
In the viewDidLoad or viewWillAppear methods for your viewController, try adding the following bit of code:
[self.myMainScrollView setContentOffset:CGPointMake(0,self.view.frame.size.width) animated:NO];
That'll scroll your larger scrollview over, so that the middle UIWebView is visible.
If that doesn't help, dig around in the UIScrollView and UIScrollViewDelegate documentation - you should find some good stuff there.
Sorry this is a pretty silly question, but I cannot think what the actual menu style is called. I'm trying to find a tutorial on how to create a instructions page that you flick through left and right to see more instructions. Basically exactly how the home screen works with dots representing how many screens there are and which screen the user is on, plus the same animation where if you flick left/right the next one slides on.
If anyone knows what these are commonly referred to as I can go look up some tutorials.
Thanks a lot,
Chris
This control is called a UIPageControl. And here's a link to a tutorial.
Use a UIScrollview with pagingEnabled.
add a UIPageControl to the view (wherever you want to see the dots).
Instruction pages should be added as subviews to the UIScrollView
Make sure to use UIScrollView and UIPageControl delegates to update the page in the pageControl.
If you need more info on how to implement this, search with keywords UIScrollView and UIPageControl
What I want to accomplish is something like this:
Two different scrollViews, and each one scrolls horizontically. Each showing 3 images, and a half one (or 1/3th) piece of the next image in the datasource of the scrollview.
Does anyone know how to accomplish such a scrollview?
I also want to be able to tap an image to flip it and show some information and a button to the detail. (See lower scrollview).
Tapping it again would just show back the image, much like the coverflow ui inside itunes, but without the coverflow being 3D...
Any help is welcome :)
Thanks in advance,
Lewion
Scroll view doesn't have a datasource. What you are looking for is standard scrolling and nothing special.. So it is definitely doable... Check the scrolling and photo scroller sample codes from apple developer samples. For more implementations of scroll view check the scroll view suite sample code and read the scroll view programming guide.
The flip animation is also a standard animation for a view and is easily doable. For example, create a utility application for iphone. It has a flip side view. See how that animation is done.
This is probably simple but I do not seem to get it to work. I have a view and inside it I have a scroll view and inside it I have a view with some labels and a button. the height of the text inside the labels changes according to some condition so I need to scroll down to see it. But whenever I try to scroll down it bounce back up without giving me a chance to view the rest of the view.
Basically, I want when I scroll down, the view to remain down as it normally should. Besides I do not see the scroll bar at all when I'm scrolling.
I know I probably do not understand how scroll views work, so I'd appreciate any help to explain to me the behavior of scroll views.
P.S. I built my whole view in a nib file and this specific setup That I mentioned at the beginning is based on a suggestion from one question I read here.
Thanks, Mohsen
you need to set content size of your scroll view
[scrollView setContentSize:CGSizeMake(360,1000)];
you can make the content size dynamic as per your calculation.
I have been facing the same nested UIScrollView problem for long time.I tried some open source codes like Scrolling madness ,three-20 and others but all fails finaly.I am trying to make a photo Viewer application same as iPhone.For that I have created the structure like this:-
1)one View controller.
2)on view of view controller one UIScrollView (i.e inner/parent scroll view) as a child.
3)on inner/parent scroll view number of child scroll views(i.e. outer/child scroll views) ,each represents one page of photos application.
4)On each scroll view one image View on which i am displaying my image.
So what I want is when user scrolls the outer scroll view it should scroll horizontally with all the child views so I will get the look and feel of paging in photos application.Also when user is on one specific image(i.e. child/outer scroll view) he should be able to zoom in/out,swipes and perform single/double tapping.I was able to make it work in sdk 2.1,but it dosnt work since sdk 3.0.Please tell me the idea behind your project.Means which scroll view you are subclassing ,in which view to detect touches.How this completely child - parent relation should be.
If possible provide any sample code also.
There is a WWDC session from 2010 that deals with this very issue.
Here's the short of it:
You need a single scroll view that is paginated and scrolls horizontally. Each "page" of that scroll view is another scroll view containing a photo.
First, it looks like you want to subclass UIScrollView? Every interaction method you need is provided for you in either the delegate callbacks or the touch methods. (Many of Apple's more advanced classes, such as UIScrollView, react poorly to subclassing.)
Second, it sounds like you have a first responder problem. IOW, your innermost scrollview isn't getting the first crack at the touch events.

I also struggled with this for a long time trying samples you mentioned. I could finally figure it out with the samples provided by apple (iphone dev center).
http://developer.apple.com/iphone/library/samplecode/Scrolling/Introduction/Intro.html
http://developer.apple.com/iphone/library/samplecode/ScrollViewSuite/Introduction/Intro.html
The first one is pretty basic and probably what u already have. The second one is all about zooming, etc. Just study these and the samples you already have, I think you will be able to figure it out. On specific topics just come back here search for answers or post another question.
EDIT: I forgot this one check out these examples by Andrey Tarantsov hosted on github. This is what you want... http://github.com/andreyvit/ScrollingMadness
