Changing background in UIView using code from XIB in ios

I created a windows-based project, then added a new view manager with xib to test the user interface, and then, entering in xib, I made some settings for the view, added some buttons and also changed the background color.

But now I want to change the background color as code, not via xib,

so I tried this in my

-(void)viewDidLoad
{
    UIColor *myColor = [UIColor colorWithRed:(128.0 / 255.0) green:(90.0 / 255.0) blue:(200.0 / 255.0) alpha: 1];
    self.view.backgroundcolor = mycolor;

}

but nothing has changed, so please help me with friends

Thanks and Regards Ranjit

#define RGBA(r, g, b, a) [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:a]

[self.view setBackgroundColor: RGB(135, 182, 44)]; //will give a UIColor objct
