The reason it was creating the white mask was because the UIToolBar doesnt allow color images on it by default. The way to accomplish this is creating a UIImage then assign a UIButton to that image. Then create a UIBarButton using initWithCustomView with the UIButton as the custom view.

Code:

     //Load the image   
     UIImage *buttonImage = [UIImage imageNamed:@"your-image.png"];

     //create the button and assign the image
     UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
     [button setImage:buttonImage forState:UIControlStateNormal];

     //sets the frame of the button to the size of the image
     button.frame = CGRectMake(0, 0, buttonImage.size.width, buttonImage.size.height);

     //creates a UIBarButtonItem with the button as a custom view
     UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];



     self.toolbarItems = [NSArray arrayWithObjects:customBarItem, nil];
     [customBarItem release];
