Ionic2：Ion Infinite卷轴无法在iPhone中运行 [英] Ionic2: Ion Infinite scroller not working in iPhone

问题描述

我在Ionic 2框架中面临无限滚动的问题，它适用于Android，但对于Iphone它没有，请帮助...

这是我的package.json：

• 问题是这也是我从哪里来的我正在获得离子框架版本2.3.0，而我在package.json中给出了不同的颜色

  • Question is this also that from where i am getting ionic-framework version 2.3.0 whereas i am giving different in package.json

    google后我发现它可能是离子版本2.3的问题.0并试图降级它，但我无法在Mac上这样做。为此，我在离子角度中更改了package.json。

    After google i found that it can be a issue of ionic version 2.3.0 and tried to downgrade it but i am unable to do so on mac. To do so i changes in package.json in ion-angular.

    请帮助

    推荐答案

    确保安装了最新的Cordova CLI :(可能需要Sudo）

    Ensure the latest Cordova CLI is installed: (Sudo may be required)

    npm install cordova -g
    

    确保已添加ios平台：

    Ensure the ios platform has been added:

    ionic platform ls
    

    如果未列出iOS平台，请运行以下命令：

    If the iOS platform is not listed, run the following command:

    ionic platform add ios
    

    如果安装了iOS平台，但版本是< 4.x，运行以下命令：

    If the iOS platform is installed but the version is < 4.x, run the following commands:

    ionic platform update ios
    ionic plugin save           # creates backup of existing plugins
    rm -rf ./plugins            # delete plugins directory
    ionic prepare               # re-install plugins compatible with 
    cordova-ios 4.x
    

    安装WKWebViewPlugin：

    Install the WKWebViewPlugin:

    ionic plugin add https://github.com/driftyco/cordova-plugin-wkwebview-engine.git --save
    

    建立平台：

    ionic prepare
    

    在iOS 9或10设备上测试应用程序：

    Test the app on an iOS 9 or 10 device:

    ionic run ios
    

    验证在iOS上安装WKWebView的一种简单方法是检查window.indexedDB是否存在。例如：

    An easy way to verify that WKWebView has been installed on iOS is to check if window.indexedDB exists. For example:

    if (window.indexedDB) {
       console.log("I'm in WKWebView!"); 
    } else {
       console.log("I'm in UIWebView");
    }
    

    所需权限

    WKWebView可能无法完全启动（deviceready事件可能无法触发），除非config.xml中包含以下内容：

    WKWebView may not fully launch (the deviceready event may not fire) unless if the following is included in config.xml:

    config.xml

    config.xml

    <allow-navigation href="http://localhost:8080/*"/>
    <feature name="CDVWKWebViewEngine">
    <param name="ios-package" value="CDVWKWebViewEngine" />
    </feature>
    
    <preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />
