I wanna make an UICollectionView like iOS Home Screen. I found several (and good) samples like:
http://mobile.tutsplus.com/tutorials/iphone/uicollectionview-layouts/
http://www.cocoacontrols.com/platforms/ios/controls/sespringboard
http://www.cocoacontrols.com/platforms/ios/controls/aqgridview
http://www.cocoacontrols.com/platforms/ios/controls/namenu
http://www.cocoacontrols.com/platforms/ios/controls/mgbox2
iOS: Are there any open-source Launcher Views like the home screen?
All libraries above work well. Editing, removing and animating is not a problem. But combining two cells into a new group, well, none of the libraries was able to do it. I heavily searched and I didn't find anything.
Does anybody know any libraries to combine two cells with drag and drop?!?!
Or at least has some tips on how to make?!?

You can use sections to group items and SupplementaryElements to decorate groups.
Or
You can also just create 2 kinds of different UICollectionViewCells: one normal cell + one group cell.
If your data source reflects grouping it should straight-forward to decide which one to return in collectionView:cellForItemAtIndexPath: .

i need to find this interface in visual studio using vb.net to use it as a booking tool for an hotel booking project.it's used select a square and show the booking form
and to show select the number of square according to the number of booking days
it's the green part in this picture
That's not one of the standard .Net controls, so you'd either need write it yourself, or buy it (if you can identify the vendor).
It looks like a 3rd party (Telerik or similar) who has controls built for this type of thing. It might be the quickest to get you up and running, but it comes with it's own issues - like not finding the support you need.
You can however put in some effort and use a default grid (recommended). This can be manually styled and adjusted to get the behaviors to the point where you need it to be (WPF exposes all you need).
Hope this helps.

I'm looking for a simple way to tell if an app is using the Okuma API. There are several applications running on a control and I don't see any indication. I've tried renaming the Okuma API dll's and I can make some of them crash by not being able to find them but that can't be the best way.
I'm writing my own app too, I want to follow the standard. Is there any built in splash screen or standard way to show an app is using the API? (Something like Intel-Inside but Okuma THINC Inside, etc) I've tried searching for the Okuma logos and I see several different versions being used but none that signify anything about API and none that really look standard for indicating API usage.
At this time there is no official logo for the purpose your describing.

I'm looking for an example xCode project that can demonstrate how to apply autolayouts to UIViews programmatically. I see quite a lot of questions that deal with how to apply autolayout, but I'm a total novice and need something to play with before I can get a feeling for how autolayouts work.
Thank you!
Take a look at this:
http://www.raywenderlich.com/20881/beginning-auto-layout-part-1-of-2 (with IB)
and this:
http://www.techotopia.com/index.php/Implementing_iOS_6_Auto_Layout_Constraints_in_Code (without IB)
In addition: If you want to do it programmatically I would prefer to use math instead of complex AutoLayout statements. If you want to have a button placed 20pixel up from bottom just work with something like [[[[UIScreen mainscreen]bounds]size]height]-20] I think this is easier to work with.

Is there any open source code for creating a piano keyboard with sounds for ios? I have looked but have not found one, or offer a good recommendation were to start, AVAudioPlayer. or systemSoundID
Here is one you can try. It is something I started a while back and have not had time to finish because of my day job.
https://github.com/yepher/MusicNotes
I found this great tutorial, it is a little advanced but perfect for learning. I already have a simple version up and running using this tutorial
http://mobile.tutsplus.com/tutorials/iphone/ios-sdk_playing-systemsoundid/
I have tried a few solutions, and eventually used this piano keyboard for iOS, since I couldn't get rid of the lag which is crucial when using it as part of a multitracker for timing issues (an app I'm working on).
I learned a lot from going over the code and through the support I got from the author, so even though it wasn't free I was very pleased with it.

I remember seeing online a (sql?) query designer tool that looked like the "point and click GUI" that you get in MSFT access (and other similar apps).
It allowed the user to do simple joins and where clauses and select clauses simply by toggling checkboxes, dragging table icons into view and connecting joins by drawing lines.
This link: Google Image Search Examples has examples.
The output was the SQL in plain text.
If anyone knows of a web-based GUI that works like this, that can be plugged into a web CMS, please link and discuss here.
Maybe WWW SQL Designer will suit you. See online demonstration.
