建议把这个方法改成下面这样

UIImage *YBIBSnapshotView(UIView *view) {
    if (@available(iOS 10.0, *)) {
        UIGraphicsImageRendererFormat *format = [[UIGraphicsImageRendererFormat alloc] init];
        format.scale = [UIScreen mainScreen].scale;
        format.opaque = YES;
        UIGraphicsImageRenderer *renderer = [[UIGraphicsImageRenderer alloc] initWithSize:view.bounds.size format:format];
        UIImage *image = [renderer imageWithActions:^(UIGraphicsImageRendererContext * _Nonnull context) {
            [view drawViewHierarchyInRect:view.bounds afterScreenUpdates:NO];
        }];
        return image;
    } else {
        UIGraphicsBeginImageContextWithOptions(view.bounds.size, YES, [UIScreen mainScreen].scale);
        [view drawViewHierarchyInRect:view.bounds afterScreenUpdates:NO];
        UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        return image;
    }
}
