如何使搜索栏角变圆 [英] How to make searchbar corner round

问题描述

我正在尝试使 searchBar 角变圆.我尝试了很多使用 layer.cornerRadius、maskToBound = true 的方法.我正在以编程方式加载 navigationBar 中的 searchBar.我已经尝试了许多关于堆栈溢出的解决方案，但没有任何效果.

I am trying to make searchBar corner rounded. I have tried many ways of using layer.cornerRadius, maskToBound = true. I am loading the searchBar in the navigationBar programmatically. I have tried many solution given on stack-overflow but nothing worked.

func setupsearchbar()
{
    //      Setup the Search Controller
    searchcontroller.searchResultsUpdater = self as? UISearchResultsUpdating
    searchcontroller.hidesNavigationBarDuringPresentation = false
    searchcontroller.searchBar.placeholder = "Search" 
    self.navigationItem.titleView = searchcontroller.searchBar
    self.searchcontroller.searchBar.layer.cornerRadius = 30
    self.searchcontroller.searchBar.layer.masksToBounds = true
    definesPresentationContext = true
    searchcontroller.searchBar.delegate = self
}

如果有什么我能做的，请帮忙.

Please help if there is anything I can do.

推荐答案

在我当前的项目中使用以下代码.

Use following code which are working fine for me in my current project.

if let textfield = searchController.searchBar.value(forKey: "searchField") as? UITextField {

    textfield.textColor = UIColor.blue

    if let backgroundview = textfield.subviews.first {

        // Background color
        backgroundview.backgroundColor = UIColor.white

        // Rounded corner
        backgroundview.layer.cornerRadius = 10;
        backgroundview.clipsToBounds = true;
    }
}

希望对你有所帮助.
