I am going to be working with a graphic designer to develop an interactive children's iphone app. It will not be a game as such, but rather a series of backgrounds with some interactive objects that can be touched to display simple animation or sound.
These I would be striving for the quality that these guys produce http://duckduckmoosedesign.com/
I assume that they would be using Quartz2D rather than embedded jpegs for their design elements?
I was wondering what tools people would recommend for designers to use that can then be imported for use an iPhone app.
I have seen some references to creating SVG in Inkscape but was wondering whether there was any other alternatives for importing graphics into Quartz for use in an iPhone app?
Opacity is a design app, that is capable to output quartzCore source code suitable for iphone or mac.

I am currently trying to implement a 3d game, in which I also need nativeiOS functionality like good integration of the applePencil (like with pencilKit).
I thought about using SceneKit but as I found a lot of information that it is not that great (https://developer.apple.com/forums/thread/117457) I went for Unity. I used the Unity as a library for SwiftUI (https://docs.unity3d.com/Manual/UnityasaLibrary.html) which worked but one withdraw is that unity always has to be opened FullScreen and I felt uncomfortable just overlaying the unity window with SwiftUI UI elements. Furthermore as I realized that Unity as a library is not available for macOS I now have to come up with a different solution anyway.
(The background is Unity, the UI is SwiftUI)
I think about using Flutter or ReatNative and combine the modules from Unity and Native iOS there. Is that a good idea, or do you propose a different solution?
In iOS, always use PencilKit is the best solution for user experience.
If you need PencilKit for Flutter, library is ready.
I want to develop a talking app for the iPhone and iPad. My question is regarding Animations only. I have an excellent 3D graphics designer who will do his part. Being a programmer, what would I need to be aware of? What should I ask the designer to provide and in what formats?
Which one to use Core Animation / Cocos 2d for development of 3d character?
I suggest that you look into OpenGL-ES if you are going to do 3D animation on iPhone/iPad.
Here is the Programming Guide for OpenGL ES on iOS devices.
I have developed one game for iphone which uses png images.It works well but which are the vector graphics images supported by iphone that i can use for my game for better quality of image like when we zoom the image the image displayed properly.which are the most common image formats that are widely used by iphone game developers?
I saw this on github a while back. It claims to render SVGs to Core Image layers. I've never used it, but I know it exists.
The only vector graphics format that is directly supported on iOS is PDF (not counting UIWebView, which also supports SVG).
Vector graphics are not typically used in games, because they're much slower to render, but that depends on what type of game you're developing. I would consider using multiple versions of bitmap images with different resolutions for zooming.
A question for the seasoned iPhone developers, what is your preference for graphics in an iPhone app? I have turned to PNGs because I read that is the preferred image format and they are the most efficient format for the OS in terms of performance. However I had read you should try to use svg graphics so they scale up on the iPad. I started reading up on svg for my next app and thought the format was natively supported by UIImageView, but it seems you can only render them in UIWebviews or programatically. My belief was a lot of the latest graphically-rich apps used svg graphics, is that an incorrect assumption?
Thanks for any advice/comments.
I think using SVG graphics would cause a ton of problems and I'm not aware of any apps that use it. It's probably a much better idea to use PNGs and just have different sizes for iPhone, iPhone 4 and iPad.
I am going to develop voip,iptv based application using QT on OS-WinXP and Platform-Atom processor for handheld device
As a application programmer point of view if I will not think about the drivers what are the other things I need to consider for this project? Like what should be the software layers in the handheld device?
I want to develop the touch screen GUI like Apple iPhone. All the widgets in QT now is window based. Can anybody suggest is there any QT widget gallery for touchscreen GUI like iPhone ?
Regarding the GUI elements in your second point, any or all of the Qt examples shown can have how they are drawn change through the use of QStyle subclasses. In addition to that, you can easily make a full-screen window, where no borders or window frames are shown. If you combine those two options (a full-screen window as background, with styled widgets on it), you can make a GUI that can appear just as nice as the iPhone GUI. The actual behavior in some widgets may be slightly different, but I'm assuming you know the basics of changing behavior via settings and subclassing.
