问题描述
请帮忙!一直盯着这个12个小时;并且已经在线查找并找不到解决方案。
Please help! Have been staring at this for 12 hours; and have looked online and can't find solution.
在我的应用程序中,我在单独的页面/控制器中使用2个UIView控件:
In my application, I use 2 UIView controls in separate pages/controllers:
- UIImageView(通过
NSData dataWithContentsOfUrl检索数据) - UIWebView
为了隔离我的代码,并使其更容易解释,我创建了一个名为MyTestApplication的新视图项目
Just to isolate my code, and make it easier to explain, I created a new view based project called "MyTestApplication"
1 - 我在委托函数中添加了一个简单的NSData dataWithContentsOfUrl。
1 - I added a simple NSData dataWithContentsOfUrl in the delegate function.
NSData *imageData = [NSData dataWithContentsOfURL:
[NSURL URLWithString:@"http://www.google.com/intl/en_ALL/images/logo.gif"]];
(由于全部使用便利功能,因此无需在此发布)
(Nothing to release here since it's all using convenience functions)
2 - 运行它以确认没有泄漏(如预期的那样)
2 - Run it to verify no leaks (as expected)
3 - 打开ViewController.xib,只需从库中添加一个UIWebView(无需连线)
3 - Open the ViewController.xib and simply add a UIWebView from the library (no need to wire it up)
4 - 运行它以验证是否有泄漏! (为什么???)
4 - Run it to verify there are leaks! (why???)
我做错了什么?请帮助!
What am I doing wrong? Please help!
如果我使用UIWebView,为什么NSData会导致内存泄漏?我只是不明白。
谢谢。
Why would NSData cause memory leak if I'm using UIWebView? I just don't get it.Thanks.
推荐答案
我也遇到了来自NSData的 dataWithContentsOfURL:
的泄漏问题iPhone模拟器。我发现当我使用其他方便方法( dataWithContentsOfURL:options:error:
)时,我不会得到内存泄漏。
I was also having trouble with leaks from NSData's dataWithContentsOfURL:
in the iPhone simulator. I found that when I used the other convenience method (dataWithContentsOfURL:options:error:
) I would not get the memory leak.
我的代码看起来像这样:
My code looked something like this:
NSURL *url = [NSURL URLWithString:urlString];
NSError *error = nil;
NSData *data = [NSData dataWithContentsOfURL:url
options:0
error:&error];
