iOS: Issue modifying button's color

I have the following code in .h file:

#import <UIKit/UIKit.h>
@interface SCLoginViewController : UIViewController
@property (weak, nonatomic) IBOutlet UIButton *btnLogin;
@end

and the following code in .m file:

- (void)viewDidAppear:(BOOL)animated
{

    [super viewDidAppear:animated];

    // Do any additional setup after loading the view from its nib.
    // Add gradient to the buttons

    btnLogin.layer.cornerRadius = 10;

    CAGradientLayer *gradientLayer = [CAGradientLayer layer];
    gradientLayer.frame = btnLogin.layer.bounds;

    gradientLayer.colors = [NSArray arrayWithObjects:
                            (id)[UIColor colorWithWhite:1.0f alpha:0.1f].CGColor,
                            (id)[UIColor colorWithWhite:0.4f alpha:0.5f].CGColor,
                            nil];

    gradientLayer.cornerRadius = btnLogin.layer.cornerRadius;
    [btnLogin.layer addSublayer:gradientLayer];

    // Add shadow
    btnLogin.layer.shadowColor = [UIColor darkGrayColor].CGColor;
    btnLogin.layer.shadowOpacity = 1.0;
    btnLogin.layer.shadowOffset = CGSizeMake(2.0, 2.0);
}

This is how the button sits on the screen:

enter image description here

Something is horribly wrong though. I know I am missing something simple, but can't figure it out. I created regular outlet called btnLogin but any change I try to make to it is not working. The button is rounded rect button. I tried Custom button and that didn't help.

Thank you!

From the image, I see that you did not make a connection from your btnLogin on the nib file to the file's owner - .h file. So this line below has no connection to the button that you are trying to make changes.

@property (weak, nonatomic) IBOutlet UIButton *btnLogin;

Once you make that proper connection, it should show up the btnLogin name where Referencing Outlets is on the image you provided.
