currently trying to make a ViewController, which include a Camera with a Overlay. I want to implement a scan function. the camera should show a field where it is scanned and save it then as a picture.
one of you has an idea? Thanks in advance!
I used this tutorial: http://www.ios-developer.net/iphone-ipad-programmer/development/camera/record-video-with-avcapturesession-2 to create a viewcontroller similar to that. The code a little old but if you make some changes you can easily create a ViewController like that.
Try this Github repo, It provides a default view controller with camera view and scan area overlay and it also provides a button to switch between the front and the back cameras.

Any insights would be greatly appreciated it. Thank you
That is a UICollection view. when you tap on the button to turn that grid into a single column grid, the cells are resized to the width of the view and reloaded again.
In my app, i need to display the status of the feedback by a Graph(chart) view.
Is webview is need?
I tried RGraph framework, which is showing errors for me, how to use this framework?
Are they're anyother ways their to achieve this?
Thanks in Advance!
Yes, this library utilizes a canvas, which you'll need a webview to display on. Some possibly helpful reading material on displaying charts:

I was reading a tutorial a while back and I saw a feature I would love to implement. It was a loading view that took the form of a UIAlertView, and you could customize the image in it and the text. If anybody knows what class that is it would be greatly appreciated. Thanks.
You perhaps are looking for UIAlertView Custom Graphics or Create a Custom Alert.
I'm a beginner with Objective-C and I have to create something similar to the one on this image but I don't know what are the components on the top bar.
Thanks in advance for any help
It looks like a navigation bar but I think a customized view with customized buttons are what it actually is.
