a log redirect to file ，建议使用最新版本

将NSLog替换为DDLog或者重新定义NSLog参见DDLog的定义可以在release模式下重向log到预先定义的日志目录 DDLoggerClient log控制器 DDLoggerManager 本地log资源管理 使用方法： 前提使用的cocopods pod 'DDLogger', '~> 1.2.5'

开始收集log

• (void)startLogWithCacheDirectory:(NSString *)cacheDirectory fileName:(NSString *)fileName;

@code

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *docDir = [paths objectAtIndex:0]; [[DDLoggerClient sharedInstance] startLogWithCacheDirectory:docDir fileName:@"log.txt"];

  return YES;

}

@endcode

停止收集log

• (void)stopLog;

当前是否显示logView

• (BOOL)isShowLogView;

显示logView

• (void)showLogView;

隐藏logView

• (void)hidenLogView;

查看本地存在的log日志

@param viewController 当前的Viewontroller

@param handler 选取回调结果

• (void)pikerLogWithViewController:(UIViewController *)viewController eventHandler:(DDPikerLogEventHandler)handler;
