analysis of OOMDetector
浅读腾讯开源OOMDetecor 内存泄漏检测源码
hook NSObject alloc add address to global hasmap
检测泄漏: 遍历global hasmap 扫描vm_region 标记是否泄漏 泄漏原理如下:
(vm_region == null && object find in stack) -> leak?
(vm_region == null && !(object find in stack) && (address object can get object isa pointer)) -> leak?
