UIWebView 加载崩溃 [__NSCFDictionary _isChargeEnabled] [英] UIWebView load crash [__NSCFDictionary _isChargeEnabled]
问题描述
我使用 UIWebView 来加载这个网站 http://www.xiami.com/song/1024665
I use UIWebView to load this site http://www.xiami.com/song/1024665
如果我触摸此站点中的视图或播放音频，有时我的应用程序会崩溃，而有时却没有，为什么?
是因为html5吗?怎么解决?其他网站没问题.
sometimes my app crashes if I touch the view or play the audio in this site and sometimes it does not, why?
is it because html5? how to solve?
other website is no problem.
崩溃日志是* -[MPTransportButton _isChargeEnabled]:消息发送到已释放实例 0x20aa58d0
crash log is * -[MPTransportButton _isChargeEnabled]: message sent to deallocated instance 0x20aa58d0
非常感谢任何帮助
---更新---
我新建了一个基于视图的项目，ViewController中的代码如下
I create a new view-base project, the code in ViewController is as following
这次是崩溃日志

项目中的源码，这次不用MPMoviePlayerController什么的了
the source code in the project, not use MPMoviePlayerController this time or something else
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [self init];
return self;
}
- (id)init
{
if (self = [super initWithNibName:nil bundle:nil])
{
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
UIWebView *web = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
[web loadRequest:[NSURLRequest requestWithURL:
[NSURL URLWithString:@"http://www.xiami.com/song/1024665"]]];
web.delegate = self;
[self.view addSubview:web];
[web release];
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
return YES;
}
- (void)webViewDidStartLoad:(UIWebView *)webView
{
}
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
//[webView stringByEvaluatingJavaScriptFromString:@"window.scrollTo(0, 10);"];
}
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error

}
推荐答案
您发布的代码没有问题.
There's nothing wrong in code that you posted.
NSZombie 表示您的代码中某处有一个 MPTransportButton 之前已被释放(释放)，之后，您的代码中的其他地方，您想做某事用它.
NSZombie says that there is a MPTransportButton somewhere in your code that was previously deallocated (released) and after that, somewhere else in your code, you want to do something with it.
我认为您在 UIWebView 的委托方法之一中执行此操作.
I think that you do it in one of your UIWebView's delegate methods.
但是... 我们需要更多代码.你在哪里alloc/init 你的MPMoviePlayerController?或者你是 alloc/init 一个 MPTransportButton 吗?
But... we need more code. Where do you alloc/init your MPMoviePlayerController? Or do you alloc/init a MPTransportButton?
