iam developing an app in which, images are to be scrolled on touchesmove i.e, swipping left /right.
I also have to display previous and next images beside present image in protrait mode.
I have seen the covertFlow sample, which is very close to my app, but i want it in horizontal mode. Please suggest me how can i acheive it , links related to it can also be helpful for me..
thanks in advance.
Well how about taking the open source CoverFlow implementation and modify it to work in portrait mode?
You can get sample code in this tapku Library
I solved my query and it is working without using any libraries.
I used the concept of lazyloading to download images, and i placed the images in scrollview which helps to scroll the images.
The following link used to load images asynchronously.

Inside the Twitter iPhone app, if you click on a link it pushes in a WebView.
Ive gotten this far, but I can't find the correct identifier for the forward and backward buttons like at the bottom left of the image below. Are they native? or are they just images they have created themselves?
You might want to have a look at a drop-in inline web view controller I did: SVWebViewController. It should save you a fair bit of coding :)
Per the list of UIBarButtonItems from the docs, those items you desire need to be custom images a they are not provided in the current SDK.
Hi
I am developing an ipad Magazine app where I need to display pdf files.I am using leaves project for page curl effect.This works great.
But in landscape page fits to height(768px) and it becomes difficult to read the font.
Thats why I want to support zoom in/out on this view.
I am a newbie to Core Graphics.I think in leaves project they parse pdf to show image of each page.But I dont know why zoom is not supported if it is an image.
There are some more branches of leaves project for implementing this feature but all of them are not perfect.
Shall I continue using leaves or UIViewAnimationTransitionCurlUp/Down will help me for both the problems?
Thanks

Is it possible to load a view when we click a coverflow image?
Please suggest how this can be done.
Here you go ;)

Please vote this post up if it helps :D
CoverFlow is not a standard iOS component. It doesn't have a public API. You'll need to either create your own or use a library someone else created.
In answer to your question, it is possible to load a view when you click an image. The iPod app probably creates a view, then uses an animation to present it onscreen.
What is the best way to create tutorial or help screens that can be viewed in an iPhone App on launch?
I'm debating between using two paradigms:
Edit a screenshot of the app with an image editing program to add static help text. Interaction is tapping or scrolling through the tips. This involves creating a custom UIViewController to advance to the next help screen.
Create a custom iPhone UIControl on top of the App user interface that can be tapped to advance to the next tutorial tip. The application will transition between the modes and will be active, rather than static. It involves adding hooks into the App's custom ViewController's to handle "TutorialUIControl" objects.
Here's some screenshots of the application that I need to make help screen UI for, it's an application that creates artwork. More App Information
Screenshot 1: View mode that allows viewers to scroll through an image list, like the UIImagePicker, but for custom image collections.
Screenshot 2: Action mode - allows viewers to select images to save to the "My Saved" album from the active art generation album "My Evolution" or evolve images using sexual/asexual image reproduction.
The "right" answer really depends on the application you are designing. I would highly suggest getting as many apps as you can and looking at how they do help. See what works and what doesn't and think about how that is related to your own design.
In my app (a game) I chose to build a set of static images that could be scrolled through to provide detailed help (based on Apple's sample code). But, I also built an interactive tutorial that plays the first time you run the game. I also pop up a welcome overlay the first time the app is run and suggest what button to press to start a game.
It also helps if you test your tutorial with a lot of different people. After several designs with things too complex, I boiled down my instructions to something extremely simple: "Press the green buttons", and then built up from there.
You can easily store a preference to say whether the app has been launched before, and if that entry is blank you run the tutorial again.
You can create an HTML tutorial that you view through a UIWebView. In on of my iPad apps, I just made a large image that I presented modally with images and text explaining how to use the app.
For iPhone, the best way to include a "How-To" tutorial for your app would have to be a web document, seeing as how you can add images and formatted text.
Alternatively, You can add more views to your controllers with transparent backgrounds and animated buttons and text, for a more interactive feel.
To answer my own questions many months later.
I revamped and used WEPopover to show my help popups, as seen in the iPhone/iPad App, Wallpaper Evolution Lite. The help disappears only if tapped or the button it was attached to was pressed. Using this flow I could highlight a series of buttons to the user.
I added help images within the application to highlight interaction behaviors with the content. The tap, zoom, and drag images are fully interactive.
As #WrightsCS mentioned HTML is another avenue. I use the UIWebView to provide a more in depth help/tips screen with contact information.
In my upcoming app, I'm making use of a paging UIScrollView with help content highlighting app features. The help screen is loaded on the first start of the app, and is accessible through a help menu option.
Here's my fork of the WEPopover github project: https://github.com/PaulSolt/WEPopover
I have to use UIScrollView as image viewer like Photo app. The UIScrollView is supposed to show photos with swiping, zooming and rotating with interface rotation.i have to load minimum 20 images.is it possible? which is the best way? plz post some sample codes.
I've written a simple and easy to use photo browser called MWPhotoBrowser which you should be able to look at and dissect.
It is an implementation of a photo viewer that I wrote allowing the user to view one or more images in a similar way to the native Photos app. It can display one or more images by providing either UIImage objects, file paths to images on the device, or URLs images online. Photos can also be zoomed, panned, and navigated with previous/next buttons.

Refer to the sample application page control here https://developer.apple.com/iphone/library/samplecode/PageControl/ , it should help you get started, they have a scroll view that you can use to scroll through a bunch of pages, you can modify this to do pictures. It doesnt do zooming o rotationg but its a good place to start
