Analyzer报告以下代码泄漏

Question

Analyzer报告以下代码可能存在内存泄漏。任何人都可以对此有所了解吗？我正在发布已经分配的注释。

  -(AddressAnnotation *)addAdress:(NSString*)placeTitle SubTitle:(NSString*)placeSubTitle Coordinate:(CLLocationCoordinate2D)coord withId:(NSInteger) placeId{
        AddressAnnotation *annotation = [[AddressAnnotation alloc] initWithCoordinate:coord];
        annotation.placeTitle = placeTitle;
        annotation.placeSubTitle = placeSubTitle;
        annotation.museumId = placeId;
        [mapView addAnnotation:annotation]; 
        return annotation;

        [annotation release];
    }

Answer 1

你在回归后释放，所以永远不会被召唤。 另请注意，地图视图会在您添加注释时保留注释。

Answer 2

更改

return annotation;
[annotation release];

到

return [annotation autorelease];
