WBAFNetworkingLogger
WBAFNetworkingLogger 是 AFNetworking 3.x 的扩展,原库中已经将原来2.x中的AFNetworkActivityLogger移除.
为方便使用,自己根据2.x中AFNetworkActivityLogger的内容,修改为AFNetworking3.x 可用的辅助类.
WBAFNetworkingLogger会监听
AFNetworkingTaskDidResumeNotificationAFNetworkingTaskDidCompleteNotification
然后打印出请求和响应的关键信息.
使用方法
和AFNetworking2.x中的使用方法一样:
直接在程序启动以后调用:
[[WBAFNetworkingLogger sharedLogger] startLogging];
默认情况下使用的是Info模式,可以通过下面方法设置具体模式,一般使用Debug模式较多:
[[WBAFNetworkingLogger sharedLogger] setLevel:WBLoggerLevelDebug];
