实现JS读取iOS本地写入的LocalStorage
判断清除缓存
if (@available(iOS 9.0, *))
{//清除缓存
NSSet * websiteDataTypes = [WKWebsiteDataStore allWebsiteDataTypes];
NSDate * dateFrom = [NSDate dateWithTimeIntervalSince1970:0];
[[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:websiteDataTypes modifiedSince:dateFrom completionHandler:^{
JMLog(@"--%@\n--%@",websiteDataTypes,dateFrom);
}];
}
配置webView 设置 WKProcessPool允许本地存储 设置单例
WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
configuration.processPool = [User shareInstanceWKProcessPool];
[configuration.userContentController addScriptMessageHandler:self name:@"pipeline"];//设置用户交互
单例
+ (WKProcessPool *)shareInstanceWKProcessPool
{
static WKProcessPool *sharedPool = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedPool = [[WKProcessPool alloc] init];
});
return sharedPool;
}
