Is there any possibility of creating a view like the following image? I do not want to keep a image like that I want iOS native coding functionality to achieve these notches.
Set your UIView background color to clear color from the code (or from the interface builder with alpha 0.0), add an UIImageView and use your image.

I am new to iOS development. How can I create a UINavigationBar like the one below? Which method do I need to override and how could I achieve a shape like that one?
You can't change the shape of the navigation bar. You can however create the illusion of the shape with custom controls and images.
I am in the process of creating an app where I have a background image (a UIImageView with the frame set to the UIView's bounds and added as a subview).
I would like to now add a UIView that will be over the background image but will apply gaussian blur to the image behind, only over the area where the UIView is.
I have just tried to use GPUImage to create a blur, which looks good but it uses 2 UIImageViews (one large background and one behind the UIView, which is blurred). Unfortunately the image no longer matches up with the background.
Is there any way to get the UIView to blur only the area behind it? A bit like the UIView is frosting the image behind.
Thanks!
Try FXBlurView from here - https://github.com/nicklockwood/FXBlurView
It should work.
I'd like to have a UIView where the user can select each of the four corners and stretch the view by independently moving them.
How would I implement such a view?
To do this, you will need to subclass UIView and handle touch events manually. When you get a touch event, you will have to do some math and then set the frame of the view to the new size. I'd recommend making the background image a stretchable image using stretchableImageWithLeftCap:topCap. It shouldn't actually be that hard.
What's the UI element that is top of that number buttons to display number ? (which is in light blue color)
It looks like a UINavigationBar with a prompt. However, the location of the gloss (which differs from your typical UINavigationBar) and the centering of the numbers (not shown) makes me think it is a custom view.
If you're trying to replicate it, I'd suggest starting with a UIView. Add a UIImageView with appropriate image for the the blue background and a UILabel for the text. Or, instead of the UIImageView, you could draw the background in the UIView's drawRect: method.
I want to build a spinner for menu selection like the one in where to? IPhone app as shown in image below. Any hints?
Doesn't need to be very hard. The easiest is probably a UIImageView with the image of the actual spinner, and another UIImageView with the yellow selection highlight (a transparent PNG) overlaying. The rotation can then be controlled with the transform property of the first UIImageView.
This should of course be nicely encapsulated in a custom UIView subclass.
