I don't know hot to start work. if any one know what is my first step for this effect then please guide me for how to stretch Hair like this.
effects Link1
effects Link2
I used following link and tutorial but not succeeded.

I think, I am going to wrong way...Plz help me.
The effect look alike it's an OpenGL object with a texture where you change the coordinates of the vertex nearest to the touch point. The OpenGL object has to be constructed out of triangles matching the form, which is probably done based on the hair image.

In my app, I want to apply different video filters like: Fade in -Out,Snow fall,Rainbow,Fast Motion,Slow Motion,etc.
I study the Brad Larson project but it does not full fill my all filter requirement.
so, Help me!!
If you need custom filters you can always write them and add to GPUImage project. Just grab some easy filter like GPUImageRGBFilter or GPUImageLineGenerator and experiment.
You can also modify OpenGL calls directly to inject your custom effects in front of a movie. Take a look at CubeExample.

I want to get height from ground level to the camera lens.Can any one suggest me a method to do this.I have Google it but could not find any solution even mathematical formula too.
pythagorean theorem is the formula you are looking for.
No idea how you might get the values to use it though, other than if there is a way to determine the distance from the camera to what it is focusing on would get you one. If you can do that, they can just point it at the ground/tap to focus and give you the height.

Skype added an anti-shake feature in it's video conference app on iPhone. How can that be done?
This is quite a complicated thing to pull off, but it's probably a combination of some powerful blur detection/removal algorithms, and the gyroscope. I would start by looking into how to detect motion with the iPhone, and see what kind of results you can get with that. If it's not enough, start looking into shift/blur direction detection algorithms. This is not a trivial problem, but is something that you could probably accomplish given enough time. Hope that Helps!

Is it possible to create app like iBooks?
I want to create app like iBooks. I want to know how i can curl the page of pdf.
Please share your ideas to create this app.
Thanks
Check out this library, might be a good starting point:
You probably want to do something like render the page as a texture to a 3d surface that is initially flat, which you could then deform and animate to provide the curling animation.

User can spin the pin and it will keep on spinning according to swipe velocity.
Please let me know how can i achieve this functionality?
Thanks.

He has taken a lot of care in creating a great valuable resource for learning iPhone development, animation in particular. You'll be ready in no time :D
In a nutshell, there are three ways you can do this.
use Cocos2D
Use CoreAnimation
Use UIView's animation methods, but I'd favor the other two solutions, especially Cocos2D since I like it :D
