使用UIWebView时内存泄漏在IOS4.0中加载请求 [英] Memory Leak while using UIWebView Load request in IOS4.0

问题描述

我有一个Web视图作为模态视图加载。使用以下代码加载网页后，我遇到内存泄漏。

  [myView loadRequest：[NSURLRequest requestWithURL：[NSURL URLWithString： url] 
 cachePolicy：NSURLRequestReloadIgnoringLocalCacheData 
 timeoutInterval：30]]; 
  

我的dealloc方法如下：

   - （void）dealloc 
 {
 myView.delegate = nil; 
 [myView release]; 
 [url release]; 
 [super dealloc] 
} 
  

仪器显示5块GeneralBlock 32泄漏，但没有可用的堆栈跟踪。 / p>

泄漏每次加载网页后都会发生，每次加载完全是5个块。如果我在页面完全加载之前关闭了modalview，则没有泄漏。如果我将缓存策略更改为NSURLRequestReturnCacheDataElseLoad，则只会在首次加载网页时发生此泄漏。

我已经尝试过以下链接中的方法，但它不工作对我来说。

任何帮助。
感谢。

解决方案

我发现几个 UIWebView 相关漏洞在iOS 4.1之前（和报告一个详细），因为我使用HTML的大量在当前iOS应用程序的本地加载我正在开发。

从4.1开始，我没有看到任何漏洞。

如果你可以用4.1重新测试，泄漏已经消失了，那么我会忽略泄漏，继续前进。我已经有应用程序批准这些类型的泄漏，因为他们在苹果框架和在您的控制之外。

I have a Web View Which loaded as a modal view. I am having memory leaks after loading a webpage using the following code.

[myView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:url]
                                     cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
                                 timeoutInterval:30]];

My dealloc method is below:

- (void)dealloc
{
    myView.delegate = nil;
    [myView release];
    [url release];
    [super dealloc];
}

Instruments showing 5 blocks of GeneralBlock 32 leaks, but no stack trace available.

The leak Happens everytime after loading the web page and is exactly 5 blocks for each loading. if I dismiss the modalview before the page is fully loaded, there is no leak. If I change the cache policy to NSURLRequestReturnCacheDataElseLoad The leak happens only for the first time loading the webpage.

I already tried the methods in below link, but it doesn't work for me.

Leak UIWebView

Any help is appreciated. Thanks.

解决方案

I have found several UIWebView-related leaks in iOS prior to 4.1 (and reported one in detail), as I use local loading of HTML heavily in the current iOS app I'm developing. They are all related to bugs with the WebKit implementation.

Since 4.1 I have not seen any of these leaks.

If you can re-test with 4.1, and the leaks are gone, then I would ignore the leaks and move on. I have had apps approved with these types of leaks, since they are in Apple frameworks and outside of your control.
