uiwebview内存泄漏

我得到以下webview内存泄漏

    initWebUILocalStorageSupport
    MobileQuickLookLibrary()

这是我的代码,我不知道我遗漏了什么。

NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10.0f];
[theRequest setHTTPMethod:@"POST"];

NSData *data = [self GenerateData];
if (data) {
    [theRequest setHTTPBody:data];
}
[webView loadRequest:theRequest];

我希望我的问题很清楚。谢谢

编辑:为GenerateData添加代码

NSArray * results = [self.managedObjectContext executeFetchRequest:request error:&error];
if (!error) {
    for (Items *item in results) {

    }
    NSString *theBodyString = [[CJSONSerializer serializer] serializeDictionary:theRequestDictionary];
    theBodyData = [theBodyString dataUsingEncoding:NSUTF8StringEncoding];
    }
return theBodyData;
