升级完Xcode 7.0发现网络访问有两个错。
1.The resource could not be loaded because the App Transport Security policy requires theuseofa secureconnection
解决办法：
（-）在Info.plist中添加NSAppTransportSecurity类型Dictionary
（二）在NSAppTransportSecurity下添加NSAllowsArbitraryLoads类型Boolean,值设为YES
2.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.
解决办法：在NSAppTransportSecurity下添加NSAllowsArbitraryLoads类型Boolean,值设为YES
