删除角半径UIButton

Question

I have applied a border and a corner radius to a UIButton in this way:

self.Button3.layer.borderWidth = 10;
self.Button3.clipsToBounds = NO;
[self.Button3.layer setCornerRadius:100.0f];

I wanted to know if there was a way to remove both of them, without doing this:

self.Button3.layer.borderWidth = 0;
self.Button3.clipsToBounds = NO;
[self.Button3.layer setCornerRadius:0.0f];

I think that this would only hide, not remove them.

Answer 1

I think that is the way to go, since CALayer provides no API to "remove" a border other than borderWidth property. According to the documentation, CALayer just "draws" the border, so, I don't think CALayer holds something like an UIView or UIImage to draw the border.

When this value is greater than 0.0, the layer draws a border using the current borderColor value. The border is drawn inset from the receiver's bounds by the value specified in this property. It is composited above the receiver's contents and sublayers and includes the effects of the cornerRadius property.
