I have downloaded the pdf reader from https://github.com/vfr/Reader. This looks great but the bottom page bar or toolbar is stable. It adds all the pages into one single tool bar with out providing any scrolling feature. could someone help me to change this to a scrollable view?
I achieved this by changing the readerpagebar to derive from UIScrollviewController instead of UIViewController and increased the content size of scroll bar to number of images mounted in it. if someone needs further info, I will post the code here.

I am new to Wix and to be honest kind of confused if there is a way to add a horizontal bar in my website.
So I have a multistate box with different states so when you press a button it takes you to that state.
What I want to do, is to somehow fit these buttons in the mobile version. I have seen that there are some components called tabs which could do the trick because they come with a default horizontal scroll bar or arrows when the content does not fit. Is there any alternative or an actual component I can add to my buttons and fix that issue?
Thank you in advance!
I am thinking to implement a custom tabbed page with some custom functionality and I thought about using MultiPage.
I am thinking about that because it seems to be the base class of the Forms's TabTabbedPage and would like to actually have a page at the bottom to display the buttons and the top space to display come content pages based on the selection(of the user).
Currently I only added 2 pages on the MultiPage and the last page from the data set is being displayed but I can't shrink its height so that I can add another content page below to add the buttons. I tried to set the HeightRequest on the pages but with no effect.
Does anyone have at hand some samples involving the MultiPage or knows how to change the ContentPage width or height?
Thanks a lot!
I am new to iPhone development. I am using Titanium for developing but I guess that hardly concerns my question.
What UI elements where used to develop the certain pages of livingsocial? There are hardly 5-6 windows in the whole app.
a) For eg: if you see the main page(daily deals,escapes,purchases,settings) - did they use a window with a black background image & then added tableview to it for the four options? each tableviewrow has different images. Is that how it could be done?
Also if you notice the four options are scrollable but the heading livingsocial stays static & looks different from the native UI. How was that done?
b) If you look at sign in page (in settings) - they have two textfields & a sign in button inside a window. For the last element (Don't have an account?), is that again a tableview inside a scrollableview?
It would be great if someone can give a general outline as to how they developed their app & what UI objects we used.
edit: please find the screen shots :

That app uses a custom made UINavigationController (for the static bar at the top, that can accommodate the title of the view and different buttons depending on the view currently showing, namely a back button for returning to the main view) and UITableView with custom made cells.
b) If you look at sign in page (in settings) - they have two textfields & a sign in button inside a window. For the last element (Don't have an account?), is that again a tableview inside a scrollableview?
No, I think that's a UIButton, that just happens to look like an isolated cell. Also, that view doesn't look like its scrollable.
I'm not familiarized with Titanium, so I can't give you any directions there. But keep in mind that using custom controls usually takes more effort than simply using apple's own default.
In answer to your first question:
I'd use a tableview for that, with custom made cells to create that look. If it is not a main window on your tab you'll have to remove the 'back' button, otherwise it'll be fine.
In answer to your second question
The first 2 are textfields. The rest are all buttons (and the text above facebook button is a label).
If you're using titanium you could take a look at the kitchensink example.
Hope this helps!

I am trying to build an app similar to USAToday i.e. each "article" is a mix of images and text that the user scrolls vertically to read if it covers more than than the size of the screen. Scrolling horizontally brings up the next article and so on.
Each article should have "paging enabled" so that the content moves as if you are turning a page in a book whether you are moving vertically or horizontally.
I must have looked at every tutorial for Scroll and Page navigation, but I am drawing a blank. Any help is much appreciated.
BTW: I have down loaded this tutorial....
http://www.edumobile.org/iphone/iphone-programming-tutorials/pagecontrol-example-in-iphone/
... but (a) it builds ok but simulator only shows a featureless black screen, and I cannot work out how to correct it, and (b) it only scrolls horizontally.
The sample code that you reference is old so I think something has changed in the SDK since then. I was able to at least get the code to run by changing the MainWindow.xib file. I opened that file in Interface Builder and then selected the Window and then in the Window Attributes Inspector I ticked "Visible at Launch". Then the tutorial would at least run and show the colors. I think you might find that there are more issues with it though.
When you are wanting to page something, the real trick is setting the content size of the scroll view.
This StackOverflow question has some good information that might help you get going.
Folks,
coming from the Java/Swing world, I am sometimes puzzled by the UI programming on the iPhone. I've spent the last hours with Googling for information but it seems that I asked the wrong questions by thinking too much in Java. Could you please point me to resources to get more familiar with the GUI concepts to be able to achive the following functionality:
Basically, I want to create a vertically scrollable view that represents structured text (for example, a recipe). Each step consists of a title and a textual description. As I want to fold and unfold such steps, the title would be somehow interactive and by clicking it the description would be displayed or hidden.
In Java, I would create a component that renders one such section. The layout manager would compute the components preferred height (with or without description being displayed).
Then, in Java, I would create a panel with a vertical layout manager and sequentially add my components. This panel would be placed in a scroll pane; the scroll pane would ask the panel to layout itself and then show a viewport on it, if for example the height is bigger than the scroll pane's height.
What Java provides me is:
layouting of elements (computing their preferred height and width), thus no need to deal with coordinates and dimensions
dynamic creation of UIs by creating and adding components during runtime
What I understood on the iPhone:
I can dynamically add views as subview to a view, e.g. a scrollview by calling addSubview
I can even remove that stuff using removeFromSubview (as explained here Clear content of UIScrollView)
What I don't understand on the iPhone:
does one view always correspond to a visible screen (I did use tab and navbar navigation so far and there whenever I set a new view, it fills the current visible screen minus the space needed for the two bars)?
or is it possible to define a view that contains a label on top ("north") and a text in center; if so, could such a view automatically determine its height?
can I realize my example in a similar way like in Java or would I need to calculate all dimensions and coordinates of the individual components on my own? (This example seems to touch on that topic: iPhone scrollView add elements dynamically with id)
Alternatively, could I use a WebView and render my stuff as local HTML using JavaScript to show or hide nodes?
Thanks for any hint or link!
There are no layout managers in Cocoa, views are being reposition according to their struts and springs settings. For information on that read the documentation: http://developer.apple.com/library/ios/#documentation/DeveloperTools/Conceptual/IB_UserGuide/Layout/Layout.html
To create a "view that contains a label on top and a text in center" you create a view with subviews - one being a label at the top, second the textview in center. If you configure struts/springs for all of subviews properly, they will autoresize when the container view is resized.
You should also get accustomed to Interface Builder, creating views in code is real pain in the ass.
