APP的看门狗，基于runtime的Swizzle Method的crash防护框架，能实时捕获导致app崩溃的破坏因子并自动修复，保持应用的健壮性。

• Unrecognized Selector Sent to Instance/class
• 容器类的数组越界，key-value参数异常
• KVO crash
  • 移除了未注册的观察者，导致崩溃
  • 重复移除多次，移除次数多于添加次数，导致崩溃
  • 观察者没有实现observeValueForKeyPath:导致崩溃
  • 添加keypath为空字符串时，导致崩溃
  • 添加或者移除时 keypath == nil，导致崩溃
• KVC crash
  • key/keypath值不正确
  • 设置的值的类型不匹配
• NSString,NSMutableString,NSAttributedString,NSMutableAttributedString(下标越界以及参数nil异常)
• NSTimer（忘记invalidate ，导致内存泄漏）
• 不在主线程刷新UI
• NSNull 方法不存在
• 野指针

• ✅ Unrecognized Selector crash
• ✅ Container crash
• ✅ KVO crash
• ✅ KVC crash
• ✅ NSString类族 Crash
• ✅ NSTimer
• ✅ NSNull

• 开启防止Crash组件

    //1. 启动所有避免crash组件
    [NFGuardDog startAvoidAllCrashWithdelegate:self];
    
     //2. 启动部分避免crash组件
    NFAvoidCrashType type = NFAvoidCrashTypeKVC | NFAvoidCrashTypeKVO;
    [NFGuardDog startAvoidCrash:type delegate:self];
    
    //3. 关闭组件
    [NFGuardDog stopAvoidCrash];
    
    //4. 实现NFAvoidCrashDelegate协议
    - (void)nf_handleAvoidCrashException:(NFCrashException *)exception{
        NSLog(@"🐞🐞🐞：you have a crash need to process，see upward⬆️");
        //To do: 你可以在这儿上传捕获的异常😎😎😎
    }

To run the example project, clone the repo, and run pod install from the Example directory first.
