IOS開發 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.
xcode自7後不再使用http，而是使用https請求，但目前很多網絡請求還只是以http請求，我們可以這樣解決
info.plist->添加@“App Transport Security Settings”字段->添加“Allow Arbitrary Loads”字段，並將對應的value值設置爲@“YES”
