-------------------------------------------------------------------------------- 1 | OCMethodTrace - Trace Any Objective-C Method Calls 2 | =========================== 3 | 跟踪打印Objective-C任何实例(类)方法 4 | 5 | ## 功能： 6 | 1. 支持任意OC实例(类)方法的跟踪打印 7 | 2. 支持多架构(arm32，arm64，i386，x86_64) 8 | 3. 支持跟踪父类和子类相同的方法 9 | 4. 支持各种灵活配置，包括方法黑白名单等 10 | 11 | ## 配置说明： 12 | ### 全局配置： 13 | #### LogLevel：Trace日志级别，对应MDTraceLogLevel，必须定义，默认值：0 14 | 0：MDTraceLogLeveError，错误级别 15 | 1：MDTraceLogLeveDebug，调试级别 16 | 17 | #### LogWhen：Trace日志输出时机，对应MDTraceLogWhen，必须定义，默认值：0 18 | 0：MDTraceLogWhenStartup ，启动即输出日志 19 | 1：MDTraceLogWhenVolume ，根据音量键控制输出日志(增加音量:输出日志;降低音量:关闭日志;默认时关闭日志) 20 | 2：MDTraceLogWhenRegexString ，输出日志包含匹配字符串才输出日志 21 | 22 | LogRegexString：日志正则匹配字符串，仅当logWhen=MDTraceLogWhenRegexString有效。日志包含指定正则字符串才输出日志 23 | 24 | #### TraceFlag：Trace控制位(尽量在该处扩展)，对应MDTraceFlag，全局必须定义，默认值：0x02，指定类可选定义，默认值：0x00 25 | 0x01：MDTraceFlagDoesNotUseDescription，跳过调用对象description方法，避免不正规的description实现导致递归 26 | 0x02：MDTraceFlagDumpClassListInfo，打印类列表信息，便于调试 27 | 0x04：MDTraceFlagDumpClassMethod，打印某个类的方法(不包括父类方法)，便于调试 28 | 0x08：MDTraceFlagDumpSuperClassMethod，打印某个类的父类方法(包括递归父类的方法)，便于调试 29 | 30 | #### TraceObject：Trace对象，对应TraceObject，必须定义，默认值：1 31 | 0：MDTraceObjectNone，屏蔽trace所有类 32 | 1：MDTraceObjectCoreClass，trace引擎指定类的方法(仅测试验证使用)，仅需要考虑CORE_CLASS_LIST 33 | 2：MDTraceObjectUserClass，trace用户指定类的方法，需要考虑USER_CLASS_LIST + "USER_CLASS_LIST和CORE_CLASS_LIST交集" 34 | 3：MDTraceObjectRegexClass，trace用户指定类 + 正则匹配类的方法，需要考虑USER_CLASS_LIST + "USER_CLASS_LIST和CORE_CLASS_LIST交集" + "匹配ClassRegexString的CLASS_LIST和CORE_CLASS_LIST交集" 35 | 36 | MDTraceObjectUserClass和MDTraceObjectRegexClass的区别： 37 | * MDTraceObjectUserClass：在考虑USER_CLASS_LIST指定的类的时候，如果USER_CLASS_LIST和CORE_CLASS_LIST存在部分交集，交集对应的类需要合并，合并算法详见：+[MDTraceClassInfo mergeInfoWithCoreInfo:userInfo:userInfo:] 38 | * MDTraceObjectRegexClass：在考虑MDTraceObjectUserClass的基础上，再考虑ClassRegexString正则匹配的类。 39 | 40 | 处理TraceObject的详细算法见：-[ MDMethodTrace parseClassListInfo]，算法内部注意优先级顺序：core > user > regex 41 | 42 | ### 指定类配置： 43 | #### USER_CLASS_LIST：用户指定类列表，必须定义 44 | TraceMode： Trace模式，对应MDTraceMode，可选定义，默认值：1 45 | 0：MDTraceModeOff，屏蔽trace方法 46 | 1：MDTraceModeAll，trace所有方法 47 | 2：MDTraceModeIncludeWhiteList，trace包含"白名单方法列表"的方法 48 | 3：MDTraceModeExcludeBlackList，trace排除"黑名单方法列表"的方法 49 | TraceFlag：定义同全局配置，但是粒度更小，属于某个类范围内，可选定义，默认值：0x00 50 | MethodWhiteList：白名单方法列表，可选定义，但MDTraceModeIncludeWhiteList时必须定义 51 | MethodBlackList：黑名单方法列表，可选定义，但MDTraceModeExcludeBlackList时必须定义 52 | 53 | 跟踪某些类的时候，该类的某些方法有可能会导致app崩溃。这时候，你可以通过多次的试验，找出导致崩溃的方法，使用黑名单模式，然后把这些异常方法放在黑名单方法列表中。当然，如果你并不需要跟踪该类全部的方法的话，也可以使用白名单模式。 54 | 55 | #### CORE_CLASS_LIST：引擎指定类列表，必须定义 56 | TraceMode：定义同USER_CLASS_LIST的TraceMode，但是仅支持MDTraceModeOff和MDTraceModeExcludeBlackList 57 | TraceFlag：定义同全局配置，但是粒度更小，属于某个类范围内，可选定义，默认值：0x00 58 | MethodBlackList：黑名单方法列表，可选定义，但MDTraceModeExcludeBlackList时必须定义 59 | 60 | #### ClassRegexString：类正则匹配字符串，仅TraceObject=MDTraceObjectRegexClass有效 61 | 每个匹配的类使用默认类配置(可以理解成一个默认的User类)。使用场景：在不确定trace哪些类的情况下，批量trace一些有规律命名方式的类，匹配字符串如：“Notification|^CM|(F|f)igCaptureSource” 62 | 63 | 64 | #### USER_CLASS_LIST和CORE_CLASS_LIST的关系： 65 | * CORE_CLASS_LIST：存在的意义在于，OCMethodTrace框架(引擎)内部也需要调用一些OC类方法，为了保证整个框架可以跑起来，避免trace到框架内部使用到的类导致的打印递归循环，所以，需排除这些指定类的全部方法或者部分方法。 66 | * USER_CLASS_LIST：用户自己指定的类，可以任意发挥。但是如果CORE_CLASS_LIST有相同的类，会优先CORE_CLASS_LIST中的配置。合并算法详见"+[MDTraceClassInfo mergeInfoWithCoreInfo:userInfo:userInfo:]" 67 | 68 | ## 技术要点： 69 | ### 支持跟踪父类和子类相同的方法 70 | SatanWoo提出了一个方法(见感谢2)，使用“runtime的消息转发机制+跳板原理(桥)”实现，流程： 71 | 每个方法置换到不同的IMP桥上 -> 从桥上反推出当前的调用关系（class和selector）-> 构造一个中间态新名字 -> forwardingTargetForSelector(self, 中间态新名字) 。 72 | 但是SatanWoo的demo(见感谢3)有两个比较大的缺陷： 73 | * 仅支持arm64平台，不支持多架构； 74 | * 仅支持实例方法，不支持类方法。 75 | 为此我做了一些改进，如下： 76 | * 支持多架构：参考objc4(见感谢4)的objc-block-trampolines.m，编写了一个通用的跳板实现，其中通过汇编支持多架构。 77 | * 支持类方法：NSObject (OCMethodTrace)需hook类方法"+[NSObject forwardingTargetForSelector:]" 78 | ### Trace输出无限循环递归的特殊处理 79 | 递归调用都发生在"-[OCMethodTrace omt_forwardInvocation:]"函数内部，有两个地方： 80 | * 对象调用自身的description导致的无限递归：为了打印对象的描述，需要调用对象的description方法，而该方法内部很可能会调用对象的其它内部方法，继而递归又调用"-[OCMethodTrace omt_forwardInvocation:]"，于是无限循环。当前解决的方法是：在"-[OCMethodTrace omt_forwardInvocation:]"开始处通过遍历函数堆栈链查找"OMTBlockRunBeforeSelector"，"OMTBlockRunAfterSelector"和"OMTDescriptionWithTargetSelector"这几个方法，可以知道是否存在递归，发现递归就不要再调用runBefore和runAfter回调即可。缺点：遍历函数堆栈链的方法实在不优雅，而且性能也受影响，需要优化！ 81 | * OCMethodTrace框架使用到的基础类导致的无限递归：比如"-[OCMethodTrace omt_forwardInvocation:]"函数范围内用到一些类：如NSDate，NSString或者runBefore或runAfter回调用到的方法等，一旦他们也被trace，也会导致循环递归。解决的思路是：把这些类放在黑名单里，不再trace。当然还有降低循环递归的方式是，内部实现尽量使用C或者C++实现。 82 | 83 | ## TODO： 84 | 1. 通过遍历堆栈链，判断是否存在循环递归调用的算法性能太差，需优化。 85 | 2. 开启全局dump类方法(MDTraceFlagDumpClassMethod)容易导致异常，不建议开启。 86 | 87 | ## 感谢： 88 | 1. https://github.com/qhd/ANYMethodLog 89 | 2.
