uniwebView插件与GUI的适配问题

这次突然被要求实现内嵌浏览器。在网上到处找资料参考，下面几个链接的内容感觉很实用

分享一下这次心得吧，以下是个人感受，技术不太好，说错了敬请纠正。

1.首先找插件，小编就找到了个UniWebView2.9，附上下载链接如下，https://pan.baidu.com/s/1HPvFzKU7WNHSvxHrKtX8zg 提取码：4g2i

2.导入之后就是这样，还有个参考Demo

3.参考网上教程:（https://blog.csdn.net/qq_37310110/article/details/79761844#commentsedit）

在UniWebViewHelper里面加个方法

public static UniWebView CreateUniWebView(GameObject go, string url, float top, float left, float bottom, float right)
{
 
        if (go == null || !go.activeSelf)
 
        {
 
            return null;
 
        }
 
        var view = go.GetComponent<UniWebView>();
 
        if (view == null)
 
        {
 
            view = go.AddComponent<UniWebView>();
 
        }
 view.insets = new UniWebViewEdgeInsets(UniWebViewHelper.ConvertPixelToPoint(top, false), UniWebViewHelper.ConvertPixelToPoint(left, true), UniWebViewHelper.ConvertPixelToPoint(bottom, false), UniWebViewHelper.ConvertPixelToPoint(right, true));
 
        view.SetShowSpinnerWhenLoading(true);
 
        view.immersiveMode = false;
 
        view.url = url;
 
        return view;
 
    }

3.后面发现报红线了

发现这个方法没有，网上那个教程也没说这个方法，只能自立更生思考怎么写了，发现这个是界面显示方法，参考官方文档不知道怎么写好，只能换种思路，继续查“UniWebView案例”。

4.终于找到了一篇“unity 网页基于 UniWebView 做UGUI 适配”https://blog.csdn.net/qq_37310110/article/details/79761844#commentsedit

private static int ConvertPixelToPoint(float num, bool v)
 
    {
 
#if UNITY_IOS && !UNITY_EDITOR
 
        float scale = 0;
 
        if(v)
 
        {
 
            scale = 1f * screenWidth / Screen.width;
 
        }
 
        else
 
        {
 
            scale = 1f * screenHeight / Screen.height;
 
        }
 
        return (int)(num*scale);
 
#endif
 
        return (int)num;
 
    }

5.创建一个新脚本OpenURL，（代码有点长，大家可以直接去上一个链接那里复制就行）

public class OpenURL : MonoBehaviour
 
{
 
    public InputField _url;
 
    public Button _enterBtn;
 
    public Button _backBtn;
 
    UniWebView _view;
 
    private void Awake()
 
    {
 
        _enterBtn.onClick.AddListener(OpenUrl);
 
        _backBtn.onClick.AddListener(CloseUrl);
 
        _backBtn.gameObject.SetActive(false);
 
    }
 
    public void OpenUrl()
 
    {
 
        if (_view != null)
 
        {
 
            _view.CleanCache();
 
        }
 
        if (_url.text == null)
 
        {
 
            return;
 
        }
 
        _view = UniWebViewHelper.CreateUniWebView(gameObject, "https://" + _url.text, 100, 0, 50, 0);
 
        _view.OnLoadComplete += View_OnLoadComplete;
 
        _view.Load();
 
    }
 
    private void View_OnLoadComplete(UniWebView webView, bool success, string errorMessage)
 
    {
 
        if (success)
 
        {
 
            //  显示 加载完成的界面 
 
            webView.Show();
 
            _backBtn.gameObject.SetActive(true);
 
        }
 
        else
 
        {
 
            //  输出 错误码 
 
            Debug.LogError("Something wrong in webview loading: " + errorMessage);
 
        }
 
    }
 
    public void CloseUrl()
 
    {
 
        _view.Hide();
 
        _view.OnLoadComplete -= View_OnLoadComplete;
 
        Destroy(_view);
 
    }
 
}
