    //You probably won't be able to use "self" in OF, 
    //so I'll let you figure out how to obtain the device's
    //the width and height from OF 
    
    float screenWidth = self.view.frame.size.width; 
    float screenHeight = self.view.frame.size.height;
    
    UIView *translucentShit = [[UIView alloc] initWithFrame:CGRectMake(0, 0, screenWidth, screenHeight)];
    [translucentShit setBackgroundColor:[UIColor blackColor]];
    translucentShit.alpha = 0.3; //set the transparency here
    [self.view addSubview:translucentShit];
    
    
    
    UIActivityIndicatorView *loadingWheel = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    loadingWheel.center = CGPointMake(screenWidth/2, screenHeight/2);
    [self.view addSubview:loadingWheel];

    [loadingWheel startAnimating];
