无法以编程方式解除/禁用iOS 11中显示的即时标记屏幕截图

Question

以下代码我在ios 10中应用，这完美无缺。但是当ios 11出现时，它会自动保存所有屏幕截图，不允许忽略即时标记截图。

for (int k = 0; k<[imgAry count]; k++) {
    UIGraphicsBeginImageContextWithOptions(imgBaseView.bounds.size, NO, [UIScreen mainScreen].scale);
    [imgBaseView drawViewHierarchyInRect:imgBaseView.boundsafterScreenUpdates:YES];
    [imgBaseView.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    CGImageDestinationAddImage(destination, image.CGImage, (__bridge 
    CFDictionaryRef)frameProperties);
}
