Kindly try the following code. i think it will satisfy your requirements.

UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:btnPush.bounds byRoundingCorners:(UIRectCornerTopRight | UIRectCornerBottomRight) cornerRadii:CGSizeMake(7.0, 7.0)];

CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame = self.view.bounds;
maskLayer.path  = maskPath.CGPath;
btnPush.layer.mask = maskLayer;

CAShapeLayer *borderLayer = [[CAShapeLayer alloc] init];
borderLayer.frame = self.view.bounds;
borderLayer.path  = maskPath.CGPath;
borderLayer.lineWidth   = 1.5f;
borderLayer.strokeColor = [UIColor blackColor].CGColor;
borderLayer.fillColor   = [UIColor clearColor].CGColor;
[btnPush.layer addSublayer:borderLayer];

Instead of setting setroundCornersOnView .You can set cornerRadius to the button. try below code. [btn_Newest.layer setCornerRadius:5];
