升級Xcode 7.0發現網絡訪問失敗
輸出錯誤信息
The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.解決方法爲：
第一步：在Info.plist中添加NSAppTransportSecurity類型Dictionary
(具體做法爲add row然後直接鍵入NSAppTransportSecurity)
第二步：在NSAppTransportSecurity下添加NSAllowsArbitraryLoads類型Boolean,值設爲YES
就ok了
