iOS13 UIImagePickerController导航栏

在选择打开相册之前

if (@available(iOS 11.0, *)) {
        [[UIScrollView appearance] setContentInsetAdjustmentBehavior:UIScrollViewContentInsetAdjustmentAutomatic];
    }

如果你的项目之前设置为UIScrollViewContentInsetAdjustmentNever，关闭相册之后记得重置。

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
    
    // 还原为 UIScrollViewContentInsetAdjustmentNever
    if (@available(iOS 11.0, *)) {
        [[UIScrollView appearance] setContentInsetAdjustmentBehavior:UIScrollViewContentInsetAdjustmentNever];
    }
    [picker dismissViewControllerAnimated:YES completion:nil];
}
