Potential leak of an object allocated

Question

Using the build and analyze of XCode I saw i have a memory leak in my code:

- (NSString *) doIt
{
    NSString *var = [[NSString alloc] init];

    return var;
}

This is of course a simplified snippet of my problem

where do i release the object?

Answer 1

This is a perfect situation for autorelease.

return [var autorelease]; will return the object with its present retain count of 1 and decrement the retain count of the object at some point in the future, after which the calling code should have retained the object if it needs to.
