iphone - 未填充自动释放的 NSMutableArray

Question

我想像这样填充一个数组:

NSMutableArray *array = [self methodThatReturnsAnArray];

在“methodThatReturnsAnArray”方法中，我创建了一个这样的数组:

NSMutableArray *arrayInMethod = [[NSMutableArray alloc] init];

当我完成填充“arrayInMethod”时，我将返回数组，为了防止内存泄漏，我正在使用:

return [arrayInMethod autorelease];

然而，“数组”变量从未被填充。删除“autorelease”时它工作正常。我应该怎么做才能确保我释放的返回对象？

+ (NSMutableArray *)buildInstants:(NSArray *)huntsArray {

    NSMutableArray *goGetObjects = [[[NSMutableArray alloc] init] autorelease];

    for (int i = 0; i < [huntsArray count]; i++) {

        NSDictionary *huntDict = [huntsArray objectAtIndex:i];

        PHGoGet *goGet = [[PHGoGet alloc] init];

        goGet.title = [huntDict objectForKey:@"title"];
        goGet.description = [huntDict objectForKey:@"description"];
        goGet.start = [huntDict objectForKey:@"start"];
        goGet.end = [huntDict objectForKey:@"end"];
        goGet.ident = [huntDict objectForKey:@"id"];

        if ((CFNullRef)[huntDict objectForKey:@"image_url"] != kCFNull) {

            goGet.imageURL = [huntDict objectForKey:@"image_url"];

        } else {

            goGet.imageURL = nil;
        }

        if ((CFNullRef)[huntDict objectForKey:@"icon_url"] != kCFNull) {

            goGet.iconURL = [huntDict objectForKey:@"icon_url"];

        } else {

            goGet.iconURL = nil;
        }

        goGet.longitude = [huntDict objectForKey:@"lng"];
        goGet.latitude = [huntDict objectForKey:@"lat"];
        goGet.companyIdent = [huntDict objectForKey:@"company_id"];

        [goGetObjects insertObject:goGet atIndex:i];
        [goGet release];
    }

    return [[goGetObjects copy] autorelease];
}

尝试使用 NSMutableArray 的便捷方法...更改:

NSMutableArray *arrayInMethod = [[NSMutableArray alloc] init];

为了...

NSMutableArray *arrayInMethod = [NSMutableArray array];

array 将返回一个自动释放的对象。
