我现在的代码删除了*.localstorage
和备份localStorage文件,但是下次打开Web视图时仍然会保留localStorage,而不管文件是否被删除。
编辑:我必须删除所有域名的localStorage! I.E.注入JS将无法正常工作。
class func clearWebViewStorage() {
let searchPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.CachesDirectory, NSSearchPathDomainMask.UserDomainMask, true).last as! String
let files = NSFileManager.defaultManager().contentsOfDirectoryAtPath(searchPath, error:nil) as! [String]
for file in files {
if file.pathExtension == "localstorage" {
NSLog("Removing localstorage file: %@", searchPath.stringByAppendingPathComponent(file))
NSFileManager.defaultManager().removeItemAtPath(searchPath.stringByAppendingPathComponent(file), error: nil)
}
}
var path = searchPath.stringByAppendingPathComponent("Backups").stringByAppendingPathComponent("localstorage.appdata.db")
NSLog("Removing localstorage backup %@", path)
NSFileManager.defaultManager().removeItemAtPath(path, error: nil)
}

我现在发现问题中的代码确实可以在手机上工作,有时候在Xcode iOS模拟器中。我很确定它与每次重建时创建新app目录的事实有关,但localStorage文件“留在后面”。我已经创建了一个新问题来回答这个问题,我将其标记为已解决,因为代码不是问题所在:iOS simulator only uses the first app folder for localStorage files but creates a new app folder for everything else

您可以尝试在UIWebView
webView.stringByEvaluatingJavaScriptFromString("localStorage.clear();")

您可以使用
NSURLCache.sharedURLCache().removeAllCachedResponses()
NSURLCache.sharedURLCache().diskCapacity = 0
NSURLCache.sharedURLCache().memoryCapacity = 0
您还可以更改NSURLRequest的缓存策略
let day_url = NSURL(string: "http://www.domain.com")
let day_url_request = NSURLRequest(URL: day_url,
cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalAndRemoteCacheData,
timeoutInterval: 10.0)
let day_webView = UIWebView()
day_webView.loadRequest(day_url_request)
