WKWebview 缓存清理

直接上代码：

- (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];

}

}
