创建和删除图层

Question

我像这样创建图层

imageView.layer.masksToBounds = YES;
imageView.layer.cornerRadius = imageView.frame.size.height / 2;
imageView.layer.borderColor = kBGColor.CGColor;
imageView.layer.borderWidth = 2.0f;
imageView.layer.rasterizationScale = [UIScreen mainScreen].scale;
imageView.layer.shouldRasterize = YES;
imageView.clipsToBounds = YES;

如何删除它？

Answer 1

删除图层的方式与删除UIView个对象

的方式相同

for (CALayer *layer in imageView.layer.sublayers) {
    [layer removeFromSuperlayer];
}
