iPhone应用程序NSNumber内存泄漏 [英] iphone app NSNumber memory leak

问题描述

我内存泄漏，不知道它来自何处以及如何解决.

I'm having a memory leak and I have no clue where it comes from and how to fix it.

在某个时刻，我计算出两个位置之间的距离.

At some point i calculate the distance between 2 locations.

double calc = [self getDistance:location to:otherLocation];
NSNumber *distance = [NSNumber numberWithDouble:calc];

在仪器中，我作为泄漏对象NSCFNumber获得，它标识

in instruments i get as leaked object NSCFNumber and it identifies

NSNumber *distance = [NSNumber numberWithDouble:calc];

是导致此问题的行.

我很茫然.请帮忙.

先谢谢了， 米歇尔

推荐答案

您在此处所做的操作没有任何问题. NSNumber的保留计数为+0(已自动释放)，因此您可能会将NSNumber保留在其他位置，而忘记释放它.

There's nothing wrong with what you're doing there. The NSNumber has a +0 retain count (autoreleased), so you're probably retaining that NSNumber somewhere else and forgetting to release it.
