奇CoreData内存泄漏

Question

当最终在仪器测试我的应用程序是否泄漏，我碰到过2个奇数泄漏：

泄露的对象：_PFArray，＃：1地址：0x2a11c0尺寸：32个字节负责图书馆：CoreData负责任的框架： newFetchedRowsForFetchPlan_MT

而且

泄露的对象：malloc的16个字节，＃：1地址：0x24d6b0尺寸：16个字节负责图书馆：CoreData负责框架：newFetchedRowsForFetchPlan_MT

堆栈跟踪˚F或者这两个泄漏点指向：

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

在CoreData Fetch中。

而且

[self.window makeKeyAndVisible]; 

什么是这些泄漏？我从来没有见过他们。当我构建和分析时，它们不会弹出。有人有任何建议吗？

谢谢！

这里是记录阵列周围的代码。记录只是在.h中声明的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];

您需要释放“记录”对象。你需要在完成使用后释放它，而不是在dealloc方法中。发布更多的代码。你是如何定义记录的？如果您需要任何帮助，请发布整个核心数据代码块。

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

要么使用

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

或本

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