WebViewWarmupper

预热 WKWebView 辅助程序。

为什么

WKWebView 初始化非常缓慢。在 UI 线程不忙的时候预先初始化可以使其更好。

安装

Cocoapods

pod 'WebViewWarmupper'

Carthage

github "simorgh3196/WebViewWarmupper"

使用

let warmupper = WebViewWarmupper(maxSize: 3)

// warmup a WKWebView instance.
warmupper.warmup()

// warmup some WKWebView instances.
warmupper.warmup(2)

// warmup WKWebView instance up to max size.
warmupper.warmupUpToSize()

let webView = warmupper.getView()

[高级] 自定义 WKWebView 初始化

class MyWebViewWarmupper: ViewWarmupper<WKWebView> {

    init() {
        super.init(maxSize: 3) {
            let script = WKUserScript(
              source: "#custom_javascript",
              injectionTime: .atDocumentStart,
              forMainFrameOnly: false)
            let contentController = WKUserContentController()
            contentController.addUserScript(script)
            let configuration = WKWebViewConfiguration()
            configuration.userContentController = contentController

            return WKWebView(frame: .zero, configuration: configuration)
        }
    }
}
