Creating a tinted UIImage from given UIImage

I have a image and want to create a black tinted image of same as shown below:

Original Image Tinted Image

I have a view and a image view as it's subview. The alpha of Image view is 0.5 and its tint color to Black color. Also the background color of view was set to black color. Using this the second screenshot is generated and I want a similar output to a new UIImage.

PS: I need a new image which can stored or reused independent of background views etc.

Also I have tried following so check before reporting duplicate:

I've also tried getting image from a view but that does not help as I've more components in view not shows here.

iPhone - flattening a UIImageView and subviews to image = blank image might help you with your problem. The idea is to "render in context" a UIView object with 2 subviews (the image, and the black overlay view) to get an image. If you have more subviews which you do not want in the image, simple hide them when rendering.
