我一直在iPhone平台上开发很短的时间，而且我已经分享了语法错误和现在的内存问题。
在我的iPhone应用程序中，图像视图通过不同的按钮（6）多次动画，这在iPhone上运行良好没有问题，但是当我第一次用仪器测试我的应用程序时，它找到了1或2个内存泄漏，当调用执行动画的IBAction和它的声音效果时会发生内存泄漏。现在我明白了内存泄漏是什么，但对防止它们知之甚少，
我是否应该担心几个kb内存泄漏，请记住我计划稍后添加更多动画？ 将非常感谢帮助。 这是我的代码：

我可以看到您分配AVAudioPlayer对象的代码可能存在内存泄漏：
sound1=[[AVAudioPlayer alloc] initWithContentsOfURL:...
我可以从您的代码中看到sound#变量是您在-(void)dealloc方法中尽职尽责的实例变量。但是，如果在课程的生命周期内多次启动该特定操作，则会发生泄漏。每次触发操作时，sound1都会获得一个全新的AVAudioPlayer对象，并立即丢失对旧对象的引用。
我建议添加以下内容：
[sound1 release];
sound1 = [[AVAudioPlayer alloc] initWithContentsOfUrl: ...
请务必设置：
sound1 = nil;
使用-(id)init方法，以便第一次拨打[sound1 release]不会造成麻烦。
更新：
防止内存泄漏的经验法则是：每当您alloc，copy或retain某个对象时，您还必须release它。
你是否担心这里和那里泄漏了几个KB？我会说是的。如果你关心你的工作，你应该尽力使它成为最好的。我不是说你从不发布内存泄漏量小的代码。我说小内存泄漏应该被认为是错误。它们应该显示在“要解决的问题”列表中，您应该尽快将其删除。
对评论的回复：
您的00001111ViewController课程应该有一个名为-(id)init的方法：
- (id)init
{
if ((self = [super init]) == nil) { return nil; }
sound1 = nil;
sound2 = nil;
//...
return self;
}
init方法中的代码在创建类的实例时运行，就像在销毁类的实例时调用dealloc方法中的代码一样。请注意，如果您的超类（00001111ViewController继承自的类）使用不同的指定初始值设定项，则应使用该方法名称。在Cocoa世界中，初始值设定项始终以init开头，但它们可能会采用其他参数，例如initWithNibName:bundle:或initWithContentsOfFile:。
另一次更新：
经过多次考虑之后，或许最好只在AVAudioPlayer方法中分配viewDidLoad个对象一次。
- (void)viewDidLoad
{
blinkTimer = [NSTimer ...
[blinkTimer setFireDate: ...
sound1 = [[AVAudioPlayer alloc] initWithContentsOfUrl: ...
sound2 = [[AVAudioPlayer alloc] initWithContentsOfUrl: ...
sound3 = [[AVAudioPlayer alloc] initWithContentsOfUrl: ...
}
完成后，您不再需要每次在startClick方法中重新创建它们。你所要做的就是在这些方法结束时调用[sound1 play]，一切都会好的。
答案 1 :(得分：1)
理想情况下，您没有内存泄漏。但你可以选择以这种方式看待它：如果每次点击只丢失几KB，并且不会有太多点击，那么这几乎不是问题。我已经看到仪器报告的内存泄漏代码不是我的（框架代码，也就是），它只有几KB，它只是偶尔发生，所以我认为它没关系。这不是一个好习惯，但浪费时间追踪无法解决的漏洞并不能很好地利用你的时间。
因此，如果您可以确定泄漏不会失控，您可以将其留在那里。但是如果这种泄漏发生了数十次或数百次，最多可以泄漏100多个KB，那么你很快就会发现自己陷入困境。您的资源在iPhone上受限，泄漏是iPhone应用程序崩溃的首要原因。
为了帮助您解决代码问题，我发现Clang Static Analyzer工具非常有用。工具here有一个GUI。它将生成泄漏报告以及代码中需要检查的其他区域。
还有一件事：Objective-C中内存管理的一般规则是，如果您分配，复制或保留对象，则必须将其释放。否则不管它。大多数泄漏都可以通过找到像[[MyObject alloc] init]这样的代码的任何地方来解决，并确保在此之后的某个时间调用[MyObject release]。

对于初学者，您可以使用init方法
然后你可能会考虑在放入图像时找到一个模式。创建一个循环的函数并将路径作为参数将图像放入数组中。

第一个答案指出静态分析仪，这绝对是一件好事。另一个好用的是动态分析器，它在运行时监视分配/解除分配和内存访问。 Valgrind是一种流行的开源动态分析器，常见于Linux上。
Valgrind can work on OSX（虽然它说它“不受支持且不完整且有错误”），并且有点骇客，有人让它在iPhone SDK executables上工作。
更好的是你可以尝试仪器，这是XCode的一部分。有一个运行它的教程here。

所以是的，仍有内存泄漏。 3日按
