核心數據，NSFetchResultsController泄漏

我不知道，如果泄漏發生在我的實現還是從蘋果的一側....核心數據，NSFetchResultsController泄漏

儀器指示我，我在這條線的漏水

如果（[自fetchedResultsController] performFetch：&錯誤]！）

我通過閱讀fetchController到地圖....這樣添加註釋：

-(void)fillMapWithAnnotations{ 

    NSError *error = nil; 
    if (![[self fetchedResultsController] performFetch:&error]) { 

     NSLog(@"Unresolved error %@, %@", error, [error userInfo]); 
     abort(); 
    } 


    for(int a=0; a<[[[fetchedResultsController sections]objectAtIndex:0] numberOfObjects]; a++){ 

     LookAround *look=(LookAround *)[fetchedResultsController objectAtIndexPath:[NSIndexPath indexPathForRow:a inSection:0]]; 
     if(look){ 
      AddAnnotation *newAnnotation=[[AddAnnotation alloc]initWithLookAround:look];  

      if(newAnnotation){ 
       [self.mapView addAnnotation:newAnnotation]; 
       [newAnnotation release]; 
       newAnnotation=nil; 
      } 
     } 
    } 



}

，我初始化我FetchController這樣的：

- (NSFetchedResultsController *)fetchedResultsController{ 
    // Set up the fetched results controller if needed. 
    if (fetchedResultsController == nil) { 
     // Create the fetch request for the entity. 
     NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; 
     // Edit the entity name as appropriate. 
     NSEntityDescription *entity = [NSEntityDescription entityForName:@"LookAround" inManagedObjectContext:managedObjectContext]; 
     [fetchRequest setEntity:entity]; 

     // Edit the sort key as appropriate. 
     NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; 
     NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; 

     [fetchRequest setSortDescriptors:sortDescriptors]; 

     // Edit the section name key path and cache name if appropriate. 
     // nil for section name key path means "no sections". 
     NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; 
     aFetchedResultsController.delegate = self; 

     self.fetchedResultsController = aFetchedResultsController; 

     [aFetchedResultsController release]; 
     [fetchRequest release]; 
     [sortDescriptor release]; 
     [sortDescriptors release]; 
    } 

    return fetchedResultsController; 
}

我儘快拿到泄漏，因爲我向後導航，在視圖控制器被釋放在我釋放我取控制器對象。

是泄漏的對象很多（與同類型的我猜的）

在此先感謝您的幫助....圍繞在我的SQLite數據庫的記錄數

我猜你的AddAnnotation類的泄漏是 – RunLoop 2010-06-26 05:40:23

yup ..我沒有發佈它的iVar ...非常感謝 – jAmi 2010-06-26 10:15:55

@JK - 你需要將你的評論移動到答案，jAmi需要檢查標記它如答覆。否則，這個問題將顯示爲永遠無法解答。 – TechZen 2010-06-26 16:49:32

正如我上面提到的，泄漏可能在您的AddAnnotation類中。
