环境:Xcode7.1.1 + iOS9.1

详细错误:

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.

原因:Xcode7 + iOS9.1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:在本地Info文件中添加下面代码即可

       <key>

                 NSAppTransportSecurity

       </key>

	<dict>

		<key>

                    NSAllowsArbitraryLoads

                </key>

		<true/>

	</dict>

也可以通过替换模板的形式替换原有文件,这样下次创好建项目,默认的就有上面这几行代码了

替换路径（注意备份原文件）：

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/Project Templates/iOS/Application/Cocoa Touch Application Base.xctemplate/TemplateInfo.plist
