I've looked at a variety of iPhone graphs, and while a lot of them work for line graphs, I have not been able to find anything that does graph annotations like the image below. Are there any graphs for iOS that support graph annotations?
There are many comparison article of the different iOS Graphing Libraries. See these comparisons for an in depth analysis of their differing features:

Not many of them support built in annotations. You may have to add that yourself. Core-Plot sounds like your best option: https://code.google.com/p/core-plot/

In mij admin i have a list of posts but this list is really really big. I want to make a send form that i can use to active an database filter (so the form gets translated to where / and / or filters). Is there some good example code that i could read or maybe a tutorial ?. Any advise ?
A nice & short previous answer on that.
The reference Matthew Weier O'Phinney's page on Zend_Form used in the Model layer
And just another one if you want
Search on goole with 'Zend_Form' and 'Model Layer' will certainly gives you some others.

Thanks in advance.
I have a requirement is that , to find only the face from selected image, and need to crop it from the original image.Is there any face detection api for it in iphone using objective c . If any one know please tell to me.
The easiest way would be to use a RESTful web service API if Internet connection is possible. You can checkout http://skybiometry.com/ for free face detection & recognition API.
