如何找到iOS中任何对象的大小? [英] How to find the size of any object in iOS?

问题描述

我正在优化我的应用程序，想知道对象的大小是多少，以便也可以在日志中显示它.

I was optimizing my app and wanted to know that how much is the size of the object, so that I can also show it in log.

假设我有

NSDictionary *temp=(NSDictionary*)[Data objectAtIndex:i];

//data is defined in the .h file 

现在我怎么知道对象温度的大小是多少?

now how will I know that how much is the size of the object temp?

我尝试使用变量视图，并在temp部分找到了

I tried using the variable view and in the temp section I found:

instance_size=(long int)30498656

instance_size是我的临时对象的确切大小吗?.

Is the instance_size the exact size of my temp object?.

我也尝试过

sizeof(temp);

但是它在那一点上崩溃了.有帮助...吗?

but it crashed on that point. Any help...?

推荐答案

编译器仅了解指针，这就是为什么它将始终返回指针大小的原因.要找到分配的对象的大小，请尝试类似

The compiler knows only about the pointer, and that is why it will always return size of the pointer. To find the size of the allocated object try something like

NSLog(@"size of Object: %zd", malloc_size(myObject));
