清除WKWebView的缓存

OC写法:     swift写法再下下面。

清除WKWebView的缓存，让H5页面一刷新就更新至最新的页面

直接上代码~！~~

要区分iOS9.0和8.0两种

- (void)deleteWebCache {

    if ([[UIDevice currentDevice].systemVersion floatValue] >= 9.0) {

        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

        }];

    } else {

        NSString *libraryPath = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0];

        NSString *cookiesFolderPath = [libraryPath stringByAppendingString:@"/Cookies"];

        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<String>, 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)

        }

    }
