Question

我有以下几处(从Amplus Low Level file Management-Remov Aliases)

NSString *resolvedPath = nil;
...
resolvedPath = (NSString*)CFURLCopyFileSystemPath(resolvedUrl, kCFURLPOSIXPathStyle);
...
return resolvedPath;

建造和安装; 分析产生以下警告:

194:3 Potential leak (when using garbage collection) of an object allocated on line 187 and stored into  resolvedPath

详细情况如下:

187:32 Call to function  CFURLCopyFileSystemPath  returns a Core Foundation object with a +1 retain count (owning reference).  Core Foundation objects are not automatically garbage collected

194:3 Object returned to caller as an owning reference (single retain count transferred to caller)

194:3 Object allocated on line 187 and stored into  resolvedPath  and returned from method  getTarget:  is potentially leaked when using garbage collection.  Callers of this method do not expect a returned object with a +1 retain count since they expect the object to be managed by the garbage collector

我是否有记忆泄漏?

如果是这样,我如何确定?

如果我不怎么防止警告?

Answer 1

我是否有记忆泄漏?

您应认为这是一种泄漏。在GC中,不保证在采集器上登记一种脂肪。仅涉及一系列类型(表面切除物体)。您应假设在采集器上登记的剪辑类型或复印件。您是不是在采集器上登记的彩虹功能中回归的,不是披露的(可能是因为动物类型是一种f类)。

如果是这样,我如何确定?

利用CFMake 电缆或NSMake 电缆

Answer 2

仅提醒您,为<代码>resolvedPath 而设定的标的,以<代码>中包含的1,除非您的方法从new alloc 或contains份、eter开始。没有任何东西可以知道,它处理的是<条码>所载明的物体,因此,它永远不会得到<条码>的<>发布<>。

将其方法名称从get改为newTarget/code>。
