ios - 如何快速设置右侧的UiSearchBar搜索图标

我正在开发Swift。

作为常规SearchBar，默认情况下，其外观类似于Follow Pic(1)。


但是根据我们的设计要求，我需要将其更改为Follow Pic(2)。



我尝试使用下面的代码，就像跟随Pic(3)



**当我尝试以下代码时，正确的 View 被隐藏起来，而我无法看到文本字段rightview

搜索图标完全不可见**

let searchField = (searchBar.valueForKey("_searchField") as! UITextField)
searchField.layer.cornerRadius = 15;


    let searchIcon = searchField.leftView!
    if (searchIcon is UIImageView) {
        print("yes")
    }

    searchField.rightView = searchIcon
  searchField.leftViewMode = .Never
searchField.rightViewMode = .Always

谁能帮我达到要求。我能理解您是否也提供 objective-c

最佳答案

试试看，然后调用viewDidLayoutSubviews()

func SearchText(to searchBar: UISearchBar, placeHolderText: String) {
        searchBar.barTintColor = UIColor.clear
        searchBar.backgroundColor = UIColor.clear
        searchBar.isTranslucent = true
        searchBar.setBackgroundImage(UIImage(), for: .any, barMetrics: .default)

        let searchTextField:UITextField = searchBar.value(forKey: "searchField") as? UITextField ?? UITextField()
        searchTextField.layer.cornerRadius = 15
        searchTextField.textAlignment = NSTextAlignment.left
        let image:UIImage = UIImage(named: "search")!
        let imageView:UIImageView = UIImageView.init(image: image)
        searchTextField.leftView = nil
         searchTextField.font = UIFont.textFieldText
        searchTextField.attributedPlaceholder = NSAttributedString(string: placeHolderText,attributes: [NSAttributedString.Key.foregroundColor: UIColor.yourCOlur])
        searchTextField.rightView = imageView
        searchTextField.backgroundColor = UIColor.yourCOlur
        searchTextField.rightViewMode = UITextField.ViewMode.always
    }
