在取消分配时尝试加载视图控制器的视图... UISearchController [英] Attempting to load the view of a view controller while it is deallocating... UISearchController

问题描述

我的代码在我的UIVIew的 viewDidLoad`中创建了一个 UISearchController。

I have code that creates a UISearchController' in my UIVIew'sviewDidLoad`.

 self.resultSearchController = ({
        let controller = UISearchController(searchResultsController: nil)
        controller.searchResultsUpdater = self
        controller.searchBar.delegate = self
        controller.dimsBackgroundDuringPresentation = false
        controller.searchBar.sizeToFit()
        controller.hidesNavigationBarDuringPresentation = false //prevent search bar from moving
        controller.searchBar.placeholder = "Search for song"

        self.myTableView.tableHeaderView = controller.searchBar

        return controller

    })()

此关闭完成后，此警告会出现在控制台中：

Right after this closure finishes, this warning appears in the console:

Attempting to load the view of a view controller while it is deallocating is not allowed and may result in undefined behavior (<UISearchController: 0x154d39700>)

我不知道我做错了什么。 这个类似的问题并不是我的情况（至少我不知道）我想是这样的）。发生了什么？

I don't get what I am doing wrong. This similar question is not really my situation (At least I don't think so). What is going on?

推荐答案

在解除分配之前，必须从超级视图中删除UISearchController的视图。 （猜它是一个错误）

UISearchController's view has to be removed from its superview before deallocate. (guess it is a bug)

Objective-C ...

Objective-C...

-(void)dealloc { 
    [searchController.view removeFromSuperview]; // It works!
}

Swift 3 ...

Swift 3...

deinit {
    self.searchController.view.removeFromSuperview()
}

我在这个问题上挣扎了几个星期。 ^^
