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.

// Background color
backgroundview.backgroundColor = UIColor.white

backgroundview.layer.cornerRadius = 10;
backgroundview.clipsToBounds = true;
}
}
