Maybe you should try changing the background colour of the view. For example make it black and add an alpha value.

For Example: 

[yourview setBackgroungColor = [UIColor colorWithRed:<#(CGFloat)#> green:<#(CGFloat)#> blue:<#(CGFloat)#> alpha:<#(CGFloat)#>]];

If you simply want to set a backgroundColor with transparency (not translucency), you assign background color like this:

yourView.backgroundColor = [[UIColor darkGrayColor] colorWithAlphaComponent:0.5f];

If this is inside UIImagePickerController, you might want to check out the cameraOverlayView property of UIImagePickerController`.

Wherever u set the view, just add this for example:

yourView.backgroundColor = [UIColor darkGrayColor];
yourView.alpha = 0.5;

U can change the background color to whatever u want...

Notice! The alpha will effect also the subviews of yourView.

So u can play with it, with some views with transparent backgrounds above yourView..

Good Luck!
