iOS11 打开系统相册 导航栏透明 且列表的frame也不对

原因应该是全局设置了UIScrollView.appearance.contentInsetAdjustmentBehavior，导致系统相册出现的问题
if (@available(iOS 11, *)) {

    UIScrollView.appearance.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentAutomatic;
}

在进入的时候
if (@available(iOS 11, *)) {

    UIScrollView.appearance.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentAutomatic;
}

在选择照片或退出时候
if (@available(iOS 11, *)) {

    [UIScrollView appearance].contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever; //iOS11 解决SafeArea的问题，同时能解决pop时上级页面scrollView抖动的问题
}
