Remove the border of the programmatically created Custom Button

Question

I know to set the border to the button by the following ways,

button.layer.cornerRadius = 0.0;
button.layer.borderWidth = 2.5;
button.layer.borderColor = [[UIColor darkGrayColor] CGColor];

But I need to know how to remove or delete the border of the button?

Answer 1

button.layer.borderWidth = 0.0;

Will make the border invisible.

Answer 2

button.layer.borderColor = [UIColor colorWithRed:0.3 green:0.6 blue:0.9 alpha:0.1];
//                                set 'alpha' to something less than 1. -----^^^

Try this !
