Best way is to create a new image (black translucent background patch) and add in the background of the superview and set the background color of superview as clearcolor.

When a button click for showing a view:

-(void)yourButtonAction
{
  [self.view setAlpha:0.3];
}

Now when removing view like an alertview.

[self.view setAlpha:1.0];

You can simply add a UIView as a subview of your controller view. Set black as the backgroundColor of it with an alphaValue between 0 and 1. Remember to set the frame equals to the viewcontroller view

In your alertview callback, just remove the view.

This is rather simple, make your new view a sub view of a view that covers the full screen with alpha set to 0.7 or something and the color of your choosing, then present this view and everything behind should be darkened.

You can just alloc a view with the main view's frame, and set the background color to gray, when you click the button, add this view and then add the specified view or you can add the specifed view in this gray view....
