objective-c - NSKeyedUnarchiver 内存泄漏

Question

我有这个代码从文件加载一组属性，然后分配它。

NSMutableData* data = [NSData dataWithContentsOfFile:fullPath];
NSKeyedUnarchiver* unarc = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];
NSMutableArray* loadedLibraries = [unarc decodeObjectForKey:@"libraries"];
IRStudyPlan* loadedStudyPlan = [unarc decodeObjectForKey:@"currentStudyPlan"];
NSMutableDictionary* loadedWordLists = [unarc decodeObjectForKey:@"wordLists"];
NSMutableDictionary* loadedStudyPlanList = [unarc decodeObjectForKey:@"studyPlanList"];
[unarc finishDecoding];
[self setLibraries:loadedLibraries];
[self setStudyPlanList:loadedStudyPlanList];
[self setCurrentStudyPlan:loadedStudyPlan];
[self setWordLists:loadedWordLists];
[unarc release];

我想知道为什么每个对象都有内存泄漏。我的 initWithCoder 就是这个，对于所有对象都相似:

-(id)initWithCoder:(NSCoder *)decoder{
if([super init]!=nil){
    [self setListName:[decoder decodeObjectForKey:@"listName"]];
    [self setWordsWithStatistics:[decoder decodeObjectForKey:@"wordsWithStatistics"]];
    [self setWordsWithStatisticsInGame:[decoder decodeObjectForKey:@"wordsWithStatisticsInGame"]];
}
return self;

}

任何人都可以启发我吗？

非常感谢
