change sub UIView background color

Question

I'm trying to add subview in my ViewController using this method

- (void)viewDidLoad
{
    [super viewDidLoad];
    addCourse = [[UIView alloc]init];
    addCourse.backgroundColor = [UIColor redColor];
    [addCourse.layer setCornerRadius:50.0f];
    [addCourse.layer setMasksToBounds:YES];
}

Where addCourse is my subview but the background color is still white. and I'm using storyboard and added the subview with it and linked the View with viewcontroller and I did write the IBOutlet and the property and synthesize but still I couldn't find a way to change the background color.

How I can change it ?

Answer 1

If you already linked with the ViewController then you just need to remove the below line from your code

addCourse = [[UIView alloc]init];

Because, it create the new instance of your subView.
