当删除注解或只是我时，MKMapView泄漏？

Question

我收到我的注释泄漏。该代码有问题（剥离下来到其承受的最低）是：

- (void)updateLocations:(NSArray *)result { 
    [mapView removeAnnotations:locations]; 
    [locations removeAllObjects]; 
    [allLocations removeAllObjects]; 
    for (NSDictionary *location in result) { 
     LocationAnnotation *annote = [[LocationAnnotation alloc] initWithInfo:location]; 
     [allLocations addObject:annote]; 
     [annote release]; 
    } 
    [self updateAnnotations]; 
} 

- (void)filterLocations { 
    for (LocationAnnotation *annote in allLocations) { 
     if (annote.typeFlag & filterFlags) { 
      [locations addObject:annote]; 
     } 
    } 
} 

- (void)updateAnnotations { 
    [self filterLocations]; 
    [mapView addAnnotations:locations]; 
} 

- (void)updateFilter { 
    [mapView removeAnnotations:locations]; 
    [locations removeAllObjects]; 
    [self updateAnnotations]; 
} 

allLocations是包含所有注释的数组（他们不一定在地图上），并且locations是保存位置的数组实际上显示在地图上。当调用updateLocations:时，添加到地图的注释中的一些（或全部，从测试变为测试）泄漏。注释的分配历史记录是：

# Category   Event Type Timestamp RefCt Address  Size Responsible Library Responsible Caller 
0 LocationAnnotation Malloc  16421111296 1  0x4953870 64  MyApp    -[MapViewController updateLocations:]

7 LocationAnnotation Release  17296397312 4  0x4953870 0  MapKit    -[MKAnnotationContainerView showAddedAnnotationsAnimated:] 
8 LocationAnnotation Retain  21832317184 5  0x4953870 0  MapKit    -[MKAnnotationContainerView removeAnnotation:] 
9 LocationAnnotation Autorelease 21832324096   0x4953870 0  MapKit    -[MKAnnotationContainerView removeAnnotation:] 
10 LocationAnnotation Release  21832350208 4  0x4953870 0  MapKit    -[MKQuadTrie remove:] 
11 LocationAnnotation Release  21920062208 3  0x4953870 0  MyApp    -[MapViewController updateLocations:] 
12 LocationAnnotation Release  21923836416 2  0x4953870 0  MyApp    -[MapViewController updateLocations:] 
13 LocationAnnotation Release  22050286336 1  0x4953870 0  Foundation   -[NSAutoreleasePool drain] 

而且看着这似乎罪魁祸首是[MKQuadTrie insert:]被调用了两次，而只有一个[MKQuadTrie remove:]被调用。我错过了什么，它是我的错，还是它在MKMapKit中的错误？

编辑：我见过的分配histroy 14 [MKQuadTrie插入：]来电，但是仅1 MKQuadTrie删除：]

好吧，我解决了这个问题对我来说

我试图消除所有的注释并添加新的（但我的代码确保它不会删除用户位置）。这是什么做的代码

我这个

[self.map removeAnnotations: [self.map.annotations filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"!(self isKindOfClass: %@)", [MKUserLocation class]]]]; 

取代了它，现在我没有得到同样的问题。
