Transparent UIImage

I am creating an iOS application in which I have added a simple UIImage. I want to add the transparency effect in image to show other images behind that main image. Tell me how I can achieve this effect?

    If you want to make the image partly see through then you would change the alpha of the image in attributes inspector on the right hand side of your Xcode program to something in between 1 and 0. An alpha of 1 is not see through at all, and an alpha of 0 means you can't see the image at all.

    In addition to using an image where the alpha channel is 0 for the pixels that you want to be transparent, and between 0 and 1 for pixels that are partly transparent, you need to put the image into an image view that has the opaque flag set to NO.
