Xcode7 使用WebView loadRequest发送HTTP请求的问题

这里写代码片出现问题的打印如下：

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.

在iOS9 beta1中，苹果将原http协议改成了https协议，使用 TLS1.2 SSL加密请求数据。

解决办法：

在info.plist中添加

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
