@xieweizhi007 谢谢 遍历所有类,去除不是工程内的,再全部添加 hook 就可以了

@kitalphaj objc_getClassList 这样的话,启动就扫描了所以的类实现了,好想也达不到这个效果, NSArray *sfl_classGetSubclasses(Class parentClass) {
int numClasses = objc_getClassList(NULL, 0);
Class *classes = NULL;

classes = (__unsafe_unretained Class *)malloc(sizeof(Class) * numClasses);
numClasses = objc_getClassList(classes, numClasses);

NSMutableArray *result = [NSMutableArray array];
for (NSInteger i = 0; i < numClasses; i++) {
Class superClass = classes[i];
do {
superClass = class_getSuperclass(superClass);
} while(superClass && superClass != parentClass);

if (superClass == nil) {
continue;
}

[result addObject:classes[i]];
}
free(classes);
return result;
}
类似这样吗

这个是逆向的看别人实现的,但是看的不是很明白,有人一起来分析一下吗
