22 | //判断方法名是否映射到某个函数实现上 23 | BOOL sel_isMapped(SEL sel); 24 | ``` 25 | 26 | 27 | ##### 出现个BUG: 28 | 既然SEL是方法的唯一标识，那不同的类调用名字相同的方法怎么办呢？ 29 | 30 | 那就让下一个重要任务出场吧。 31 | #### IMP 32 | 定义：函数指针，指向方法实现的首地址。 33 | 代码定义如下： 34 | 35 | ``` 36 | typedef id (*IMP)(id, SEL, ...); 37 | ``` 38 | 其参数包含id,SEL,后面试实际的参数列表。 39 | 那么，XX调用了XXX方法，其参数为XX都确定下来了。 40 | 41 | ##### IMP的高级作用 42 | 既然上述元素都确定下来了，那么就可以直接绕过Runtime的消息传递机制，直接执行IMP指向的函数了。省去了一些列的查找，直接向对象发送消息，效率会高一些。 43 | 44 | ``` 45 | IMP imp_implementationWithBlock(id block)//根据代码块获取IMP,其实就是代码块与IMP关联 46 | IMP method_getImplementation(Method m) //根据Method获取IMP 47 | [[objc Class] instanceMethodForSelector:SEL]//根据OC方式获取IMP 48 | ``` 49 | 50 | 51 | 当我们获取一个方法的IMP时候可以直接调用IMP 52 | 53 | ``` 54 | IMP imp ＝ method_getImplementation(Method m)； 55 | id objc ＝ imp(id,SEL,argument);//objc用来保存方法的返回值，id表示调用这个方法的对象，SEL是Method的选择器，argument是方法的参数。 56 | ``` 57 | 58 | 59 | #### Method 60 | 61 | Method定义如下：它主要是用语描述类里面的方法 62 | 63 | ``` 64 | typedef struct objc_method *Method; 65 | ``` 66 | objc_method结构体定义如下 67 | 68 | ``` 69 | struct objc_method { 70 | SEL method_name OBJC2_UNAVAILABLE;//方法名 71 | char *method_types OBJC2_UNAVAILABLE;//参数返回值字符串描述 72 | IMP method_imp OBJC2_UNAVAILABLE;//方法的实现 73 | } 74 | ``` 75 | 76 | 从上述代码可以看出，Method是一个结构体，包含了SEL和IMP成员变量。 77 | 实际上，相当于在SEL和IMP之间做了一个映射，有了Method，SEL就可以找到对应的IMP，从而调用方法。 78 | 79 | 80 | ##### Method操作函数如下： 81 | 82 | ``` 83 | 方法操作主要有以下函数： 84 | // 添加方法 85 | BOOL class_addMethod ( Class cls, SEL name, IMP imp, const char *types ); 86 | 87 | // 获取实例方法 88 | Method class_getInstanceMethod ( Class cls, SEL name ); 89 | 90 | // 获取类方法 91 | Method class_getClassMethod ( Class cls, SEL name ); 92 | 93 | // 获取所有方法的数组 94 | Method * class_copyMethodList ( Class cls, unsigned int *outCount ); 95 | 96 | // 替代方法的实现 97 | IMP class_replaceMethod ( Class cls, SEL name, IMP imp, const char *types ); 98 | 99 | // 返回方法的具体实现 100 | IMP class_getMethodImplementation ( Class cls, SEL name ); 101 | IMP class_getMethodImplementation_stret ( Class cls, SEL name ); 102 | 103 | // 类实例是否响应指定的selector 104 | BOOL class_respondsToSelector ( Class cls, SEL sel ); 105 | ``` 106 | 107 | 此处具体实现比较简单，可以通过手动操作IMP来完成方法的调用。 108 | 109 | 实例代码： 110 | 111 | 112 | ``` 113 | #import "OC_IMP.h" 114 | 115 | 116 | typedef void (^CustomBlock)(NSString *name); 117 | 118 | @interface OC_IMP () 119 | 120 | @property(nonatomic, weak) CustomBlock block; 121 | 122 | @end 123 | 124 | @implementation OC_IMP 125 | 126 | - (void)testIMP { 127 | [self addMethodByIMP];

138 | Method m = class_getInstanceMethod(self.class, @selector(testIMP)); 139 | method_setImplementation(m, impBlock); 140 | const char * types = method_getTypeEncoding(m); //因为方法类型相同（都是无参数无返回值类型，所以方法类型相同，如果知道的话，可以直接制定type为v16@0:8） 141 | sel_registerName("newSel"); //注册newSel 142 | BOOL isAdded = class_addMethod([self class], @selector(newSel), impBlock, types); 143 | if (isAdded == YES) { 144 | NSLog(@"添加成功"); 145 | [self performSelector:@selector(newSel)]; 146 | } 147 | } 148 | 149 | @end 150 | ``` 151 | 152 | 153 | ``` 154 | OC_IMP *oc_imp = [[OC_IMP alloc] init]; 155 | [oc_imp testIMP]; 156 | ``` 157 | 158 | 调用执行结果 159 | 160 | ``` 161 | 2017-07-14 20:14:26.359 OCDeepLearning[5654:530015] 添加成功 162 | 2017-07-14 20:14:26.359 OCDeepLearning[5654:530015] 执行block 163 | ``` 164 | 165 | 166 | 补充： 167 | 1. 在swift里可以使用#selector(XXX)来获取对应的SEL,但这并非指swift的方法调用是通过selector来实现的，能调用仅仅是因为swift和OC的混编； 168 | 2. 每个方法名有对应的唯一seletor,其SEL相同，但对应的IMP函数指针不同。 169 | 170 | -------------------------------------------------------------------------------- /appletrace.framework/.gitignore: -------------------------------------------------------------------------------- 1 | .DS_Store 2 | .idea/ 3 | .vscode/ 4 | cmake-build-debug/ 5 | CMakeLists.txt 6 | 7 | # Prerequisites 8 | *.d 9 | 10 | # Object files 11 | *.o 12 | *.ko 13 | *.obj 14 | *.elf 15 | 16 | # Linker output 17 | *.ilk 18 | *.map 19 | *.exp 20 | 21 | # Precompiled Headers 22 | *.gch 23 | *.pch 24 | 25 | # Libraries 26 | *.lib 27 | *.a 28 | *.la 29 | *.lo 30 | 31 | # Shared objects (inc.
