奇CoreData內存泄漏

Question

當最終在儀器測試我的應用程序是否泄漏，我碰到過2個奇數泄漏：

泄露的對象：_PFArray，＃：1地址：0x2a11c0尺寸：32個字節負責圖書館：CoreData負責任的框架： newFetchedRowsForFetchPlan_MT

而且

泄露的對象：malloc的16個字節，＃：1地址：0x24d6b0尺寸：16個字節負責圖書館：CoreData負責框架：newFetchedRowsForFetchPlan_MT

堆棧跟蹤˚F或者這兩個泄漏點指向：

records = [[self.managedObjectContext executeFetchRequest:request error:&error] retain]; 

在CoreData Fetch中。

而且

[self.window makeKeyAndVisible]; 

什麼是這些泄漏？我從來沒有見過他們。當我構建和分析時，它們不會彈出。有人有任何建議嗎？

謝謝！

這裏是記錄陣列周圍的代碼。記錄只是在.h中聲明的NSarray。

/* 
Fetch existing events. 
Create a fetch request; find the Event entity and assign it to the request; add a sort descriptor; then execute the fetch. 
*/ 
marblebeingdragged=YES; 
NSFetchRequest *request = [[NSFetchRequest alloc] init]; 
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Child" inManagedObjectContext:_managedObjectContext]; 
[request setEntity:entity]; 

// Order the events by creation date, most recent first. 
NSSortDescriptor *nameDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:NO]; 
NSSortDescriptor *prizeDescriptor = [[NSSortDescriptor alloc] initWithKey:@"prize" ascending:NO]; 
NSSortDescriptor *neededDescriptor = [[NSSortDescriptor alloc] initWithKey:@"marblesneeded" ascending:NO]; 
NSSortDescriptor *colorDescriptor = [[NSSortDescriptor alloc] initWithKey:@"color" ascending:NO]; 
NSSortDescriptor *reachedDiscriptor = [[NSSortDescriptor alloc] initWithKey:@"prizereached" ascending:NO]; 



NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:nameDescriptor,prizeDescriptor,neededDescriptor,colorDescriptor, nil]; 
[request setSortDescriptors:sortDescriptors]; 
[nameDescriptor release]; 
[colorDescriptor release]; 
[prizeDescriptor release]; 
[neededDescriptor release]; 
[reachedDiscriptor release]; 
[sortDescriptors release]; 

// Execute the fetch -- create a copy of the result. 
NSError *error = nil; 
records = [[self.managedObjectContext executeFetchRequest:request error:&error] retain];

您需要釋放「記錄」對象。你需要在完成使用後釋放它，而不是在dealloc方法中。發佈更多的代碼。你是如何定義記錄的？如果您需要任何幫助，請發佈整個核心數據代碼塊。

records = [[self.managedObjectContext executeFetchRequest:request error:&error] retain]; 
//.... code using records 
[records release]; 

編輯：

要麼使用

records = [[self.managedObjectContext executeFetchRequest:request error:&error]]; // no retian 

或本

records = [[[self.managedObjectContext executeFetchRequest:request error:&error] retain] autorelease];
