Quartz in Xcode 4 - objective-c

i would like to implement a quartz composition into my iOS app in xcode 4. Despite searching everywhere for an explanation on how to do this, i have come up empty. Thank you for your help.

There is no Quartz Composer for iPhone, therefore, no Quartz Compositions.
Unless your willing to do it through Safari, (i.e. a UIWebView)

How to deal with the ios Launch files

It has been a while since I created my last app and I missed the change with the launch file (since titanium 5.2.0).
I want my app to have a custom splashscreen (full screen image). In the past I used the various png files for the splashscreens Default.png, Default#2x.png etc.
I'm testing with the launch file and the custom Storyboard. At the moment it's not clear to me how I can achieve the behavior i want: A full screen image in the splash screen.
What is the best approach?
Thanks for the help.
Go to http://docs.appcelerator.com/platform/latest/#!/guide/Icons_and_Splash_Screens-section-29004897_IconsandSplashScreens-iOSgraphicassetrequirementsandoptions and take a look at the Purpose column. You'll see 9 splash screen sizes. You have to make each of them and put them in app/assets/iphone. Note that you have to name them exactly as told in the table.
This worked for me, Ti-5.4.0 tested on iPhone 7, iPad Air, iPhone 4S and iPhone 6S Plus.
Since version 5.2 storyboards were introduced. You can use them or you can disable it and use the "old" method to implement splashscreens.
To disable it, add this to tiapp: (of course, within the existing ios section in tiapp
<ios>
<enable-launch-screen-storyboard>false</enable-launch-screen-storyboard>
</ios>
To use it, look at the documentation how to implement it correctly.

NSStatusItem app development

I'm beginning some OS X development, I am reasonably accomplished with objective C and UIKIT.
There doesn't seem to be as much online about moving from iOS development to OS X as I thought there would be!
Anyway, I found a decent tutorial over a Ray Wenderlich, that basically explained the differences, (multiple NSWindows, then add to them NSViewControllers etc)
What I would like to do is make a little app that shows info in the status bar (beside the Wifi icon etc)
Basically all it does is have an NSStatusitem that has it's title set with info I want shown (e.g. current song title)
I've got one going and it's working ok so to my question:
I've got Application is agent (UIElement) (so I cannot see a dock icon or menubar)
The code for my little app all resides in the app delegate, now from iOS dev i'm sure this is not the right place for this code, but since the app is a just a status bar item, that has it's title updated I don't think I need a UIViewController etc....
Where should my apps logic go?
Anything online to transition from iOS to OS X?
As you dont have much work with NSWindows and NSViews, you surely dont need NSWindowController or NSViewController.
And I think for this kind of app even your AppDelegate class is enough and best place to put all your logic.
If you have some models then you can break your code upto that, and use it in the AppDelegate itself.
Transition from iOS to OSX.
If you are good in Objective-C then you dont have to worry about few more Cocoa-Controls especially GUI levels, you have full support of Documentation.
Switching between iOS to OSX, vice-versa is not to difficult, but yes if you end up with system level then you need to interact with OSX too.
As stated earlier, if you know Objective-C well, then you should not face major problems. However, there are some differences. I found these following documents helpful:

Scaling for multiple devices

So I am creating an app that will be released in the App Store available for iPhone 4/4s and iPhone 5.
In my project I am using storyboard for the interface.
At the moment not every object is able to aline perfect with the objects above so when I for example test on iphone 4 every thing gets messed up.
How can I fix the place of the object.
Do I have to hardcode this? Or can I use storyboard for this.
I think autolayout should suffice in most cases. You can check out a comprehensive tutorial here: http://floatlearning.com/2012/11/designing-for-multiple-screens-in-ios/

Make Image Spin Until Stopped - Xcode Mac App

I have a png of a gear the I want to react just like an NSProgressIndicator, so that when a process is happening, it spins, and when nothing is happening, it stops. I am new to Xcode stuff, so sorry if I get terms wrong or just look stupid... This is a mac app so I am guessing it is different then iOS app development.
Here you have a recently written guide to doing exactly what you want to do
Let me know if you need some of it explained!

Wikitude API for iPad 2

with the introduction of iPad 2, I would like to use the Wikitude API in my present app which is available for iPhone, unfortunately I cant figure out how to make that my POIs appear in the whole screen, and not just in a section which is the size of an iPhone screen.
I have tried to modify the xibs, but it doesnt work.
Do you have any idea of how to achieve this?
Thanks in advance.
unfortunately the Wikitude API currently does not support the iPad2 - it is iPhone only at the moment.
Best regards,
Nicolas
The Wikitude SDK does support iPads since 2012 - find the iOS version here:
