iOS(oc)与vue交互

1、oc调用vue方法

  methods:{
            hwajax:function (strings) {
                this.tokenString=strings;
            }
        }

需要暴露方法

  mounted:function () {
            window.hwajax = this.hwajax;
        }
// 页面加载完成之后调用在iOS里面调用js方法:
- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation {
    NSString *jsStr = @"hwajax('lvkaike')";
    NSLog(@"%@",jsStr);
    [webView evaluateJavaScript:jsStr completionHandler:^(id _Nullable d, NSError * _Nullable error) {
        NSLog(@"%@",d);
        NSLog(@"%@",error);
    }];
}

2、oc 调用vue方法

 methods:{
    onLineCollectionFun:function () {
        var u = navigator.userAgent;
        //android终端
        var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1; 
        //ios终端
        var isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/); 
            if(isAndroid){
                   window.android.ocOnLineCollectionFun();
             }else {
                   console.log('在线收款')
                    window.webkit.messageHandlers.ocOnLineCollectionFun.postMessage({'methodsID':'1'});
              }
    }
}

wkwebview代理设置

#import 
@interface GuestHomeController ()
@property(nonatomic,strong) WKWebView * webView;
@property(nonatomic,weak) MBProgressHUD*hud;
@end

初始化wkwebview

WKWebView*webV=[[WKWebView alloc] initWithFrame:[UIScreen mainScreen].bounds configuration:configuration];
[self.view addSubview:webV];
_webView=webV;
webV.backgroundColor=[UIColor groupTableViewBackgroundColor];
webV.UIDelegate=self;
webV.navigationDelegate=self;
NSString * urlString = @"";
urlString = [kBaseWebURL stringByAppendingString:@"guesthome"];
[webV loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]];

第一步.我们需要在WKWebView创建的过程中初始化添加ScriptMessageHandler

WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
configuration.userContentController = [WKUserContentController new];
[configuration.userContentController addScriptMessageHandler:self name:@"ocOnLineCollectionFun"];

然后实现代理方法.监听JS的回调.为了查看效果,代码如下所示.

- (void)userContentController:(WKUserContentController *)userContentController didReceiveScriptMessage:(WKScriptMessage *)message {
    HWDLog(@"%@", message.body);
    HWDLog(@"%@", message.name);
    NSDictionary * body = [message.body objectForKey:@"body"];
    if ([message.name isEqualToString:@"ocOnLineCollectionFun"]) {
        [self onLineCollectController];
    }
}

暴露方法,这步很重要

  mounted:function () {
            window.onLineCollectionFun = this.onLineCollectionFun;
        }

vue里调用方法使用:
this.onLineCollectionFun()
