首页 / 移动开发 / IOS / iOS使用UIWebView 请求出现App Transport Security has blocked a cleartext HTTP (http://)

错误描述：

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 beta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。

解决方法：

在info.plist 加入key

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