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

funcClearCache() {

letdateFrom: NSDate= NSDate.init(timeIntervalSince1970: 0)

if#available(iOS9.0, *) {

letwebsiteDataTypes: NSSet= WKWebsiteDataStore.allWebsiteDataTypes()

WKWebsiteDataStore.defaultDataStore().removeDataOfTypes(websiteDataTypes as! Set, modifiedSince: dateFrom) {

print("清空缓存完成")

}

} else{

letlibraryPath = NSSearchPathForDirectoriesInDomains(.LibraryDirectory, .UserDomainMask, true)[0]

letcookiesFolderPath = libraryPath.stringByAppendingString("/Cookies")

leterrors: NSError

try? NSFileManager.defaultManager().removeItemAtPath(cookiesFolderPath)

}

}
