#import <JavaScriptCore/JavaScriptCore.h>
#import<WebKit/WebKit.h>
1、遵守3个代理 <WKNavigationDelegate,WKScriptMessageHandler,WKUIDelegate>
2、@property (nonatomic, strong) WKWebView *webView;
3、self.view .backgroundColor =[UIColor whiteColor];
WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
//注册方法名称，iOS与js保持一致
[configuration.userContentController addScriptMessageHandler:self name:@"clickFunc"];
self.webView= [[WKWebViewalloc]initWithFrame:self.view.boundsconfiguration:configuration];
self.webView.UIDelegate = self; //记得实现对应协议,不然方法不会实现.
self.webView.navigationDelegate =self;
[self.viewaddSubview:self.webView];
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"h5地址"]]];
4、实现代理方法
- (void)userContentController:(WKUserContentController*)userContentController didReceiveScriptMessage:(WKScriptMessage*)message
{
NSLog(@"message.name====%@ body=%@",message.name,message.body);
if([message.nameisEqualToString:@"clickFunc"]) {
[selfclickFunc];
}
}
5、- (void)clickFunc
{
NSLog(@"111111");
}
6、js调用window.webkit.messageHandlers.约定的方法名称.postMessage(参数);
