如何从自身更改UITextField边框？

Question

I have MYTextField inherited from UITextField .

I call [self changeBorderColor] method inside MYTextField that looks like that:

self.layer.masksToBounds = YES;
self.layer.borderColor = (__bridge CGColorRef _Nullable)([UIColor brownColor]);
self.layer.borderWidth = 1;

But nothing happen. Is there way to do that?

Answer 1

instead of self.layer.borderColor = (__bridge CGColorRef _Nullable)([UIColor brownColor]);

write self.layer.borderColor = [UIColor brownColor].CGColor;

Answer 2

By using the layer property you can do like this way,

tf.layer.cornerRadius = 25.0f;
tf.layer.masksToBounds = YES;
tf.layer.borderColor = [UIColor brownColor].CGColor;
tf.layer.borderWidth = 1.5f;
