In Simulink is there a way to disable grid snapping? And if so how is it done programmatically? I can't seem to find anything in their documentation about disabling this.
As of Simulink R2013b (the only one I tested it on), there is a way. View > Smart Guides toggles on or off the snap feature.
There could be earlier versions that support this feature as well. I just don't have any earlier versions.
It seems that this is not possible.

I am new to Unity. I have done a character walk animation in 3ds max and imported in Unity. I created Xcode project for iOS through Unity, and animation works as expected.
I want to develop some UI button controls on screen and animate this animation in my iOS app, only when this button is clicked. How do i code it now for this UI controls and events? Do i need do adding these controls and events on the Xcode project (which created by Unity) (or) I can do everything like this kind of native code in Unity itself?
Please advise!
Thank you!

You can do all UI in the Unity itself. You have these options:
Old Unity GUI system. It is pretty easy to program, but it is awful in terms of performance and usability for designers — it's created completely from code, with no editors. It's almost never used in commercial products except for debugging and developer tools. However, it's still a good option for prototypes.
Use other GUI package. There are a lot of 2d and UI packages for Unity of all kinds. Currently the most popular one is NGUI, which is pad, but also has an evalution version.
Create your own UI framework (still in Unity). Just wanted to mention that this is a viable option, but it's obviously the worst one for your case.
Wait for the new 2D/GUI Unity framework. It's supposed to come out in 4.3 version, and it is just around the corner; more than that, the original NGUI author is working on it.
In you place, I'd create basic prototype controls with built-in Unity3d GUI, and by the time I'd need to create something more presentable, new Unity GUI would hopefully already be there.
I'm creating an AIR app, but I realized that it doesn't seem to natively support the "fling" momentum. I thought I'd ask if anyone out there has created an object or plugin that would put this back in? Currently, on the objects I want to fling, I'm recreating the momentum, but it's not perfect yet. Could anyone put me onto the right path in doing this?
Thanks!
I ended up creating my own fling, and it works great.
I keep the last 3 touchmove locations and times in memory, then on touchend, I find the difference between the most recent and oldest touch in memory, to find speed and direction. Then I used Actuate to ease it a certain distance past that if necessary.
It took a lot of tweaking to make it feel natural, though.
Greensock has a great plugin which works just like iOS native flick, and can be customized to work in an array of ways. Performance in Air is superb even on older iPads. For best results use BitMask.
I have seen a few grids made with UITableView but I don't really like how close together each cell is to the other. If there is a way of creating a grid system like the home screen on an iphone (the screen after it is unlocked) if would be great. I don't need an exact solution but a point in the right direction, maybe a set of libraries to look through would be great. I am running xcode 4.4.1
Thanks!
The key is UIScrollView has a paging mode (since could have more buttons than fit in the view). It's covered here's in Apple ocs:
http://developer.apple.com/library/ios/#documentation/WindowsViews/Conceptual/UIScrollView_pg/ScrollViewPagingMode/ScrollViewPagingMode.html
If you use that, each 'page' would have n buttons/views that when clicked would call a protocol/delegate call back for the consumer with the data to handle and it would evenly layout the UIView/buttons across that page view. Contact me if you want my sample.
You probably don't want to require iOS6 as a minimum requirement but if you do, you can do as H2CO3 suggested in the comment and us UICollectionview. Here's a tutorial: http://www.raywenderlich.com/22324/beginning-uicollectionview-in-ios-6-part-12
There's also some open source launchers that you can look into their code. Here's some (I'm sure there's more).

Code is at: https://github.com/sarperdag/SESpringBoard

Use UICollectionView. You can create grid type views using that. It is available in iOS 6.
If you can target iOS 6+, use UICollectionView. It's one of the best new things in iOS for years and it will be as important as UITableView.
The layout you're asking for is only a few lines of code.
NSHipster has a good explanation of UICollectionViews and Ray Wenderlich has a good tutorial.
(There's lots of example code out there, but here's a very simple example project I did recently for another question involving UICollectionViews)
I am using the undocument CGSSetWindowWarp function. Unfortunatly, in Lion, it stopped working properly (it works but all mouse events are dropped)
Is someone else encountering teh same issue and have a workaround?
Thanks and regards
From what I understand, CGSSetWindowWarp is primarily used by the Dock to transform windows which are in the process of being minimized. From this standpoint, disabling mouse events is kind of a feature (since it prevents you from accidentally clicking controls in a rapidly transforming window) -- it's unlikely to be fixed.
Xcode4 introduced the gray-rounded-square style non-modal alerts that momentarily appear as required. For an example, see 'Build Succeeded'. iirc, this style of non-modal alert is also used elsewhere in Lion.
Now, also iirc, I believe I saw some official iPhone sample code showing how they recommend this effect is achieved in iPhone Apps, but I can't find it again. I'd like to use in my App this to achieve a consistent style.
If someone recalls what I'm talking about, I'd appreciate a link. Thanks.
I think you're talking about the bezel notification style? On iOS, I know SSToolkit has support for such a display (under HUD View).
Another way: This uses MBProgressHUD and provides sample code.
I think you can do it using a momentary UIActivityIndicator. Something like this
EDIT: or this
EDIT: The idea is the same, a custom activity indicator. The above answer gives you some more specific links to your problem. But well it is an activity indicator you're looking for.
