这里，栈最后能看到的是EAGLView.mm:324 if(!)这一行，搜了一下类似的情况都是按Home键切后台时候出现的，可是我这个是随时都会出，又不一样。
另外输出有Client(2452,0x1987b0310) malloc: *** error for object 0x14000f5f8: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
应该是哪里释放过度了，但是自己的代码检查了也没有查到。
有遇到类似情况的吗？
