I'm developing an app and I wish use the UIImagePickerController but I wish let the user to choose some images saved into my app, not the photolibrary.. it's possible to do this??
thanks in advance!!
The short answer is that that's not the way UIImagePickerController is designed, unfortunately. I've seen several projects have to reimplement this feature in their own (different) ways before moving forwards.
As a good first pass tutorial at this problem I would recommend this site
It relies on a simple UIScrollView and custom views to do the job. I've also seen solutions to the problem that use custom UITableViews as well as a couple other solutions.
No you can't. You can either select from the photo library or take a new picture. This is probably one of the most annoying things I've come across in the API. If you have to have this functionality, you will have to find an open source version or develop your own UIImagePickerController. I have used this with some success.

I have an interactive flash animation which i need to be able to use on an iPhone, embedded within an iPhone app.
I'm not able to link the animation here but a screenshot of the interface (which is pretty self explanitory) can be found here - http://imgur.com/i4bUgTB
It's a very simple interaction with just dragging answers into boxes and checking whether the answers are correct. My question is what would the easiest/best way to convert this to something that can be used on the iPhone?
My initial thoughts would be to use Canvas but i've not looked deeply into what it can do so I was hoping that someone could point me in the right direction.
Thanks for your advice.
Flash embeds logic inside it via scripts. What you are referring to is not an "animation" but a working application.
You should check this link if you use Actionscript 3, I never did that myself.
If the scenario of the app is as you describe, then using your flash sources inside your iOS app shouldn't be too difficult to achieve IMHO.
Can't find anything about this anywhere (maybe there's a good reason...) - does anyone know if there are any libraries for creating simple SWFs in iOS? I'd like to be able to let the user build a simple animation, then email it off as a SWF. If it's not possible, I'll probably go down the animated gif route.
Thanks for any help!
You might use libsswf which has a c interface.
Check here.
i am working with a customer feedback application here i am planing to add some animations like on click of next question one cloud should come n drop the questions or some thing like that, can i do that using core graphics or should i use openGL? can any one give me some sample codes or tutorial links?
I say stay with CoreAnimation as long as you can and only use OpenGL if really need to. Most things are easily doable with CA, and you get lots of features for free (smooth animations, fading, ...).
You can do this using CAKeyFrameAnimation. You will easily find some sample of this. Try google my friend.
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.
I'm working on an iPhone app and I need to be able to display images to users. I have already gotten the code that takes the photo and stores it into the filesystem working well. Now I just need to figure out how to display the image.
I've looked at the Three20 project I've read about on a few of the posts here, but it seems a bit cumbersome and like an extra dependency to import link and combine all of the Three20 library into my little app.
Are there any other ways or a more streamlined library that will let me display photos to my users?
Thanks!

Throw a UIImageView on the screen? Or ask a more specific question if that is not what you want.
