注册此类全局函数指针应该保存之前的注册,并在自己的实现中回调回去,否则如果其他组件也想检测malloc调用,就会被后来的注册者冲掉 ``` malloc_logger_t *oom_pre_malloc_logger; - (void)registerMallocLogger { //save previous if (malloc_logger && malloc_logger != common_stack_logger) { oom_pre_malloc_logger = malloc_logger; } malloc_logger = (malloc_logger_t *)common_stack_logger; } ``` ``` extern malloc_logger_t *ra_oom_pre_malloc_logger;...
