Subview sublayers overlap higher subviews

I have a problem: I am creating UIView

which is returned from the method and this part is fine, but I noticed that when I add sublayers to one of the subzones, these layers overlap the subviews that are higher in the hierarchy (textView and imageView), the subwords added in testViewCopy

, appear on top of these subzones, and they shouldn't. I don't know what's going on here to cause this.

code:

- (void)makeShareImages
{
    UIView *shareView = [self shareView];

    UIView *testViewCopy = [shareView viewWithTag:0];

    NSUInteger currentIndex = 1;

    for (NSDictionary *sub in self.array)
    {
        NSArray *lastArray = [sub objectForKey:@"LastArray"];

        for (NSDictionary *dict in lastArray)
        {
            @autoreleasepool
            {
                currentIndex ++;

                CircleLayer *layer = [[CircleLayer alloc]init];
                layer.portrait = [[dict objectForKey:@"Portrait"]boolValue];

                layer.frame = testViewCopy.bounds;

                [testViewCopy.layer addSublayer:layer];

                NSData *frameData = [self getSnapshotDataFromView:shareView];

                NSString *savePath = [NSString stringWithFormat:@"%@/%lu.png",somePath,(unsigned long)currentIndex];

                [frameData writeToFile:savePath options:0 error:nil];
            }
        }
    }
}

- (UIView *)shareView
{
    UIColor *bgColor = self.containerView.backgroundColor;

    CGSize size = self.containerView.bounds.size;

    UIView *viewToShare = [[UIView alloc]init];
    viewToShare.backgroundColor = bgColor;
    viewToShare.layer.cornerRadius = 6.0;
    viewToShare.layer.masksToBounds = YES;

    UIView *testViewCopy = [[UIView alloc]init];
    testViewCopy.backgroundColor = [UIColor clearColor];
    testViewCopy.contentMode = UIViewContentModeScaleAspectFit;
    testViewCopy.layer.masksToBounds = YES;
    testViewCopy.tag = 0;

    UITextView *textViewCopy = [[UITextView alloc]init];
    textViewCopy.backgroundColor = [UIColor clearColor];
    textViewCopy.tag = 1;
    textViewCopy.textContainerInset = self.textView.textContainerInset;

    UIImageView *profileImageViewCopy = [[UIImageView alloc]initWithFrame:CGRectMake(2, 2, 32, 32)];
    profileImageViewCopy.contentMode = UIViewContentModeScaleAspectFit;
    profileImageViewCopy.layer.masksToBounds = YES;
    profileImageViewCopy.image = [self profileImage];
    profileImageViewCopy.tag = 2;
    profileImageViewCopy.layer.cornerRadius = profileImageViewCopy.frame.size.width / 2.0;

    viewToShare.frame = CGRectMake(0, 0, size.width, size.height);
    testViewCopy.frame = CGRectMake(0, 0, size.width, size.width);
    textViewCopy.frame = CGRectMake(0, 0, size.width, size.height);

    NSAttributedString *attributedStringCopy = [[NSAttributedString alloc]initWithAttributedString:self.textView.attributedText];

    textViewCopy.attributedText = attributedStringCopy;

    [viewToShare addSubview:testViewCopy];
    [viewToShare addSubview:textViewCopy];
    [viewToShare addSubview:profileImageViewCopy];

    return viewToShare;
}

- (NSData *)getSnapshotDataFromView:(UIView *)view
{
    UIGraphicsBeginImageContextWithOptions(view.bounds.size, NO, 0.0);
    [view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *snapShot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return UIImagePNGRepresentation(snapShot);
}
