Hi I was wondering is there any tutorial on how to make a photo/collage app like Picstitch on Xcode? Or is there any sourcode available around? I would like to learn.
Thanks
None that I know of. Google is your friend.
Also check stack overflow, github, SourceForge, etc.
Tutorials tend to be limited to small snippets of code to show you how to complete a single task.
I could pretty easily put together a tutorial that would show how to combine several images onto a larger "canvas" but it would be a low-level tutorial on how to create a graphics context and draw images into it. I would not include all the UI you would need for a collage app like selecting images from the camera roll, letting the user drag around the images before he generated the collage, displaying previews, a UI for saving/printing the output, etc.
Creating a full featured application ends up being pretty involved.
