iOS 13 - 当搜索主动推送到其他 VC 时，该 VC UITableView 在 Swift 4 中的 NavigationBar 下 [英] iOS 13 - When Search Active Push to other VC then that VC UITableView goes under the NavigationBar in Swift 4

问题描述

我在 iOS 12 中检查过它工作正常.问题是当我要搜索并推送到第二个 VC 时它工作正常.当我反复推送到第二个 VC 时，UITableview 会位于 NavigationBar 下方.正常推送仅在搜索活动和第二次推送时才能正常工作.

I have check this in iOS 12 it's working fine. Issue is when I am going to search and push to second VC it working fine. when I back and again push to second VC then UITableview goes under the NavigationBar. Normal push working fine only issue when search active and push second time.

1. UnderTopBar
2. forKeyPath:"hidesShadow"
3. edgesForExtendedLayout
4. 自动调整ScrollViewInsets
5. extendedLayoutIncludesOpaqueBars
6. self.view 布局也是.

It's working for me. I hope it's working for you too.

Objective-C

-(void)viewWillDisappear:(BOOL)animated{
    if (@available(iOS 13.0, *)) {
        [self.navigationController.view setNeedsLayout]; 
        [self.navigationController.view layoutIfNeeded];
    }
}

斯威夫特

func viewWillDisappear(_ animated: Bool) {
    if (@available(iOS 13.0, *)) {
         self.navigationController?.view.setNeedsLayout()     
         self.navigationController?.view.layoutIfNeeded()
    }
}

如果这不起作用，请检查操作系统版本 13.1.3.我认为它有效.
