KillBug

揪心的bug

我们通过第三方工具分析捕获 mach信号或unix信号获取崩溃信息，但有时明明查到了具体的崩溃地点，确觉得这行代码似乎找不出问题。

崩溃无法复现，这个问题可能就不了了之了，崩溃率也就居高不下。

那有没有一个办法可以记录下来用户的操作步骤用于复现呢？可不可以记录现场？

于是我花了一天的时间写了这款工具：KillBug

bugtags 中也有KillBug的功能。我们之前使用过，并成功的把崩溃率降低到了十万分之一。用户交互日志功不可没。

此工具用来收集用户操作步骤：

1、可用于bug复现，问题排查
2、分析用户操作日志

采用 runtime method swizzle 实现，为了不影响app的启动速度，method swizzle 需要手动开启。

支持Swift、OC以及混编项目。

目前支持采集如下内容：

///单例
+ (instancetype)shared;

/// 普通 UIControl
- (void)trackEventView:(UIView *)view;

/// tableview&collectionview
- (void)trackEventView:(UIView *)view withIndexPath:(nullable NSIndexPath *)indexPath;

/// viewWillAppear
- (void)trackViewWillAppear:(UIViewController *)controller;

/// uiapplication 活跃状态
- (void)trackApplication:(NSString *)state;

/// uiapplication 死亡信息
- (void)trackApplicationDeadReason:(NSString *)reason;

/// 用户的touch事件
- (void)trackTouch:(NSString *)info;

/// 日志回调
- (void)debugInfoHandler:(DebugInfoHandler)handler;

使用

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    KBAutoTrackManager *manager = [KBAutoTrackManager shared];
    [manager debugInfoHandler:^(NSString * _Nonnull info) {
        NSLog(@"%@", info);
        /// Custom 
    }];
    return YES;
}
