ios - Xcode中NSString的死存储和潜在泄漏

一个字符串的位。使用以下代码（示例进行了简化）时，我会不断收到有关停货和潜在泄漏的通知：

int x = 0;
NSString *aString = [NSString alloc]init]; <-- value store to 'aString' during its     initialization is never read

if(x == 0)
{
  aString = @"This is a string set by x being 0";
} else
{
  aString = @"This is a string set by x being something else";
}

aTextLabelOutlet.text = aString;
[aString release];
<-- Potential leak of an object allocated online ... and stored into aString

我不太明白。它被分配一次，然后在使用后释放。它被初始化，然后总是放一些东西，并且总是被读取。

它从不崩溃或实际上不会导致内存泄漏，所以我有点困惑。

最佳答案

您不应该为NSString分配aString，因为您在aString部分中分配给if。

这应该足够了：

int x = 0;
NSString *aString;

if(x == 0)
{
  aString = @"This is a string set by x being 0";
} else
{
  aString = @"This is a string set by x being something else";
}

aTextLabelOutlet.text = aString;
