ios - 我应该在声音中发布 NSBundle 吗？

Question

我应该在下面的代码中释放 NSBundle 吗？ NSURL 是否也应该发布？我很困惑。

NSBundle  *mainBundle = [NSBundle mainBundle];
NSError   *error;
NSURL     *audioURL = [NSURL fileURLWithPath:[mainBundle pathForResource:@"count_in" ofType: @"mp3"]];
AVAudioPlayer *player1 = [(AVAudioPlayer*) [AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:&error];
self.player =   player1;
[self.player play];
[player1 release];

Answer 1

你不应该释放 NSBundle 和 NSURL 实例，因为你还没有分配它们。

来自苹果文档。

You take ownership of an object if you create it using a method whose name begins with “alloc”, “new”, “copy”, or “mutableCopy” (for example, alloc, newObject, or mutableCopy), or if you send it a retain message.

You use release or autorelease to relinquish ownership of an object. autorelease just means “send a release message in the future” (specifically: when the used autorelease pool receives a drain message—to understand when this will be, see “Autorelease Pools”).

我强烈建议您清除内存管理概念。
