Swift版本:

if #available(iOS 9.0, *) {
  let websiteDataTypes = NSSet(array: [WKWebsiteDataTypeDiskCache, WKWebsiteDataTypeMemoryCache])
  let date = NSDate(timeIntervalSince1970: 0)
  WKWebsiteDataStore.defaultDataStore().removeDataOfTypes(websiteDataTypes as! Set<String>, modifiedSince: date, completionHandler:{ })
} else {
    var libraryPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.LibraryDirectory, NSSearchPathDomainMask.UserDomainMask, false).first!
    libraryPath += "/Cookies"

    do {
      try NSFileManager.defaultManager().removeItemAtPath(libraryPath)
    } catch {
      print("error")
    }
    NSURLCache.sharedURLCache().removeAllCachedResponses()
}

Swift3版本:

   if #available(iOS 9.0, *)
    {
        let websiteDataTypes = NSSet(array: [WKWebsiteDataTypeDiskCache, WKWebsiteDataTypeMemoryCache])
        let date = NSDate(timeIntervalSince1970: 0)

        WKWebsiteDataStore.default().removeData(ofTypes: websiteDataTypes as! Set<String>, modifiedSince: date as Date, completionHandler:{ })
    }
    else
    {
        var libraryPath = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.libraryDirectory, FileManager.SearchPathDomainMask.userDomainMask, false).first!
        libraryPath += "/Cookies"

        do {
            try FileManager.default.removeItem(atPath: libraryPath)
        } catch {
            print("error")
        }
        URLCache.shared.removeAllCachedResponses()
    }

在iOS 9中

//// Optional data
NSSet *websiteDataTypes
= [NSSet setWithArray:@[
                        WKWebsiteDataTypeDiskCache,
                        //WKWebsiteDataTypeOfflineWebApplicationCache,
                        WKWebsiteDataTypeMemoryCache,
                        //WKWebsiteDataTypeLocalStorage,
                        //WKWebsiteDataTypeCookies,
                        //WKWebsiteDataTypeSessionStorage,
                        //WKWebsiteDataTypeIndexedDBDatabases,
                        //WKWebsiteDataTypeWebSQLDatabases
                        ]];
//// All kinds of data
//NSSet *websiteDataTypes = [WKWebsiteDataStore allWebsiteDataTypes];
//// Date from
NSDate *dateFrom = [NSDate dateWithTimeIntervalSince1970:0];
//// Execute
[[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:websiteDataTypes modifiedSince:dateFrom completionHandler:^{
   // Done
}];
