How to change wallpaper in iPad programmatically?
You can't do this. The user decides what wall paper s/he wants and has one, single place to change it. You can, however, add new items to the user's saved photos list, which they can choose from when they change their wallpaper.
Apparently, it is possible: see this link:
You can save pictures to your iPad's photo album or directly to wallpaper -- a neat feature.
Quite likely, it's a private api, that only Apple can use in their iAds, but I'm still interested in how they accomplish that.
As far as I know, iAds are basically just little HTML5 web sites, so, the call would be part of the html code. It shouldn't be to difficult to figure out what's going on.

In the iOS Human Interface Guidelines under the Live Photos section Apple says this,
"Make sure that users can distinguish a Live Photo from a traditional
still photo. It’s especially important to help users make this
distinction when they can share the photo. The best way to show users
that they’re viewing a Live Photo is to display a little movement that
gives a hint of the experience. In cases where a hint isn’t possible,
you can display the system-provided badge on the Live Photo. A Live
Photo never displays a playback button that looks like a video
playback button."
I am kind of confused on how to provide that little hint of movement in my live photo. How do I provide that hint of movement?
You don't need to dissect a Live Photo into still frames and construct an animated UIImage, or dig out the Live Photo's movie file... It's much simpler.
Display your user's Live Photo content in a PHLivePhotoView.
Call startPlaybackWithStyle: and pass
.Hint for the playback style to get the "hint" that the HIG is talking about.
There's no step three.
I've designed the User Interface of an iPhone app and I wish to show an online demo of that consisting for the moment of a series of static images representing the main steps of the app.
According to you what is the best way to do this simulation?
You know, something like a series of single webpage, optimized for mobile, containing a single image linking to the next step, but I was wondering if exists a much elegant and sophisticated solution, with a transition effect for example or other features.
I hope I was clear enough :)
Any help will be sincerely appreciated.
Thanks in advance for your attention.
This sounds like a good use for Briefs Briefs App Website. This pretty much allows you to create an interface and step through it as if it were an application. I believe you'll need to have a developer account to run the app that will read the brief on your phone (since it wasn't able to be released in the app store).
An alternative to static images would be to make a video. I use the iShowU video screen capture tool and set it to record the iPhone/iPad simulator window. I then run through the screens, type inputs, etc. In addition to recording the video, the program records my voice as I narrate the app's features.
As to transition effects, the video will capture whatever transition animations are in your program.
In the end you have a video that you could give your user, put on YouTube, or whatever.
You can do this easily and for free on AppDemoStore. You just have to upload the app screenshots and then add hotspots which are used for the navigation through the demo.
AppDemoStore offers also the sophisticated features you are asking for:
iPhone specific transition effects such as slide up/down/left/right, fade and flip
gestures icons for the hotspots
text boxes and callouts
multiple hotspots on a screen in order to create a simulation of the app (and not just a linear demo)
Here's a sample demo: http://www.appdemostore.com/demo?id=1699008
Moreover, the demos created on AppDemoStore run in any browser and mobile device and can be embedded in your webpage or blog (like you do it with a YouTube video). With the FREE account, you can create up to 10 demos with unlimited screenshots and all the features specified above.

I'm using source code from apple (SquareCam) and I would like to figure out how I can use the photos taken in that app and see them in a library (like the photos app) without having all the other photos the user has taken elsewhere like in the regular camera.
I'm not too great at making apps yet so I'm pretty noobish.
I've gotten as far as opening the photo library but nothing else. no viewing individual photos or the options such as emailing, messaging and what not.
Don't think you can do that. It either all photos or no photos...
You can of course save the photo in your own documents directory and write your own photo viewer - there's quite some code and frameworks around that do most of the job, see e.g. the answers to this so question:
Open source photo viewer for IPhone
I'm building an iPhone app for existing site (a local news site)
Main page with articles headers, when click on them you move to the article page. Simple.
This is the first time I'm building such type of app.
I have 3 general questions, just to make sure :
For the iphone, Do we need to
re-create the website article's
pictures for the iphone ? or there
is some programming tool that on the
fly make the files looks better on
the iphone ? or maybe, there is some
technique that creates one artice
picture that looks right both for
the server and the iphone ?
Usually, Do you need to create
special data channels from the
iPhone webservice ? or programmers
just use the existing rss channels
of the webserver ?
If someone know nice artice about
this stuff, It will help a lot. just
see what other are doing.
thanks.
You can see the intent Media apps, these apps are working like what you want your app to.
1) You're better off creating mobile versions of the images. You can do image processing on the iPhone, but you'll have to have the original and that makes the whole thing pointless (ie. you have to download the whole thing.) Generate a mobile thumbnail when those are uploaded on the server.
2) RSS will do. There's a very good tutorial at cocoadevblog.com about approaching such a task (I guess this covers 75% of the work you have to do)
3) Check 2) ;-)
if your download image is bigger the the thumbnail you are trying to display,
then the problem is in your code that change the image size. check carefully what are you doing to the image after downloading it.
I would recommend to create square thumbnails of your pictures at the server level. This will allow you to easily position in the iPhone screen, plus you will not need to download the whole image from the server.
nnahum
this might sound silly but since i am new to iPhone i wanted to ask this question... :P
Where is the UIWebView best used? I mean which type of application?
Could i use that if i wanted to display a video in some part of the screen rather than fullscreen which MPmediaPlayer is really good at?
Thanks :)
The only places I have seen UIWebView really used in a way that is right is for help pages. Developers will make this page call a FAQ page hosted on their servers so that they can change the contents frequently without going back to Apple for review.
