你好我有一个UIWebView泄漏内存问题基本上我有我的WebView显示页面,链接在另一个控制器的UITableView中.我用带有导航器的WebView推送控制器,并将带有retain属性的链接传递给它.
我尝试过互联网上的所有内容,例如:
[[NSUserDefaults standardUserDefaults] setInteger:0 forKey:@"WebKitCacheModelPreferenceKey"];
//Clear cache of UIWebView
NSURLCache *sharedCache = [[NSURLCache alloc] initWithMemoryCapacity:0 diskCapacity:0 diskPath:nil];
[NSURLCache setSharedURLCache:sharedCache];
[sharedCache release];
sharedCache = nil;
[[NSURLCache sharedURLCache] removeAllCachedResponses];
这是我的代码:
-(void) viewWillAppear:(BOOL) animated
{
NSMutableURLRequest *_req=[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:link] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:120];
[_req setHTTPShouldHandleCookies:NO];
[self setMyRequest:_req];
[req release];
}
[webView loadRequest:myRequest];
-(void) viewWillDisappear:(BOOL) Animated
{
[webView stopLoading];
[webView loadHTMLString:@"<html></html>" baseURL:nil];
}
- (void)dealloc {
[myRequest release];
[webView stopLoading];
[webView release];
[link release];
[super dealloc];
}
现在我只在模拟器4.2和4.3上测试,我使用xcode 4,当我点击导航器上的后退按钮时,我得到了这个泄漏.
这是我的tableview控制器的代码
- (void)viewDidLoad {
webViewController=[[ItemDetail …
