Xcode 7 ATS设置

这两天研究SDWebimage库，在xode 7上运行过程中遇到了些问题，创建的新项目由于使用到了https的图片URL，运行后，怎么都不出现图片，发送请求时，报下面的错：

“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”

经过搜索stackoverflow查询相关问题发现，iOS9新特性要求App内访问网络请求要采用HTTPS协议，无论url是http的还是https的。通过进行如下设置即可：

在Info.plist中添加 NSAppTransportSecurity 类型 Dictionary ; 在 NSAppTransportSecurity 下添加 NSAllowsArbitraryLoads 类型Boolean ,值设为 YES;

然后尝试了SDWebimage不同的图片加载方法，均成功展示。后面可以正常研究图片缓存的实现了。
