我遇到了UIWebview
问题。当我使用URL加载数据内容时,应用程序崩溃。它发生在一个月的某个时间。我非常厌倦它,我无法重现它。它发生在客户端的设备上。请帮帮我。在ios7.1使用url加载数据内容时UIWebview中的内存泄漏(WebCore :: CachedResource :: unregisterHandle)
- 异常类型的应用程序运行:EXC_BAD_ACCESS(SIGSEGV)
- 异常亚型:KERN_INVALID_ADDRESS”
- 线程2名:WebThread
- 线程2毁损:0的WebCore 0x38322b02 的WebCore :: CachedResource :: unregisterHandle(WebCore :: CachedResourceHandleBase *) + 110 1 WebCore 0x38322a8a WebCore :: CachedResourceHandleBase ::〜CachedResourceHandleBase()+ 14 2 WebCore 0x384b77fe WebC矿石::的MemoryCache :: pruneDeadResourcesToSize(无符号整数)+ 278 3 WebCore的0x38396aee WebCore的::的MemoryCache ::剪枝()+ 94"
以下是我们的源代码。
if ([defaults boolForKey:@"cacheEnabled"]) {
[[NSURLCache sharedURLCache] setMemoryCapacity:[defaults integerForKey:@"cacheSize"]];
} else {
[[NSURLCache sharedURLCache] removeAllCachedResponses];
[[NSURLCache sharedURLCache] setMemoryCapacity:0];
}
NSURL *url = [NSURL URLWithString:[defaults objectForKey:@"connectionURL"]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)
{
if ([data length] > 0 && error == nil) [self.webView loadRequest:request];
else if (error != nil) NSLog(@"Error: %@", error);
}];
在dealloc方法:
[_webView setDelegate:nil];
[_webView stopLoading];
感谢先进的!
