解开XCode开发工具的http协议限制问题

问题内容

使用XCode8.1开发IOS应用，使用WebView做一个网页demo，结果中途出现很多问题，第一是发现NSURL在XCode8.1的swift3版本下需要用URL替代，另外一个就是XCode默认不开启http请求的问题。运行日志内容如下：

objc[9876]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x118128998) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x117f4dd38). One of the two will be used. Which one is undefined.
2016-11-07 20:28:06.887 test3[9876:357348] App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

最下面的内容意思就是：

应用程序默认暂时屏蔽了不安全的HTTP协议（http：/ /）。如果想允许，可以通过您的应用程序的Info.plist文件配置。

解决

使用Open As Source Code的方式打开项目根目录下的info.plist文件,在最后结束的位置加入：

    <key>NSAppTransportSecuritykey>
    <dict>
        <key>NSAllowsArbitraryLoadskey>
        <true/>
    dict>

下面是全部文件内容，可以参考增加的位置：

<plist version="1.0">
<dict>
    <key>LSApplicationCategoryTypekey>
    <string>string>
    <key>CFBundleDisplayNamekey>
    <string>string>
