WKWebView|WKWebView 的清理缓存

oc:

// 清理clearWKWebViewCache缓存 - (void)clearCache { if ([[[UIDevice currentDevice]systemVersion]intValue ] >= 9.0) { NSArray * types =@[WKWebsiteDataTypeMemoryCache,WKWebsiteDataTypeDiskCache]; // 9.0之后才有的 NSSet *websiteDataTypes = [NSSet setWithArray:types]; NSDate *dateFrom = [NSDate dateWithTimeIntervalSince1970:0]; [[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:websiteDataTypes modifiedSince:dateFrom completionHandler:^{ }]; }else{ NSString *libraryPath = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,NSUserDomainMask,YES) objectAtIndex:0]; NSString *cookiesFolderPath = [libraryPath stringByAppendingString:@"/Cookies"]; NSLog(@"%@", cookiesFolderPath); NSError *errors; [[NSFileManager defaultManager] removeItemAtPath:cookiesFolderPath error:&errors]; } }

swift:
// MARK: - 清空缓存 func ClearCache() { let dateFrom: NSDate = NSDate.init(timeIntervalSince1970: 0) if #available(iOS 9.0, *) { let websiteDataTypes: NSSet = WKWebsiteDataStore.allWebsiteDataTypes() WKWebsiteDataStore.defaultDataStore().removeDataOfTypes(websiteDataTypes as! Set, modifiedSince: dateFrom) { print("清空缓存完成") } } else { let libraryPath = NSSearchPathForDirectoriesInDomains(.LibraryDirectory, .UserDomainMask, true)[0] let cookiesFolderPath = libraryPath.stringByAppendingString("/Cookies") let errors: NSError try? NSFileManager.defaultManager().removeItemAtPath(cookiesFolderPath) } }
