一个简单的ObjC与JavaScript交互封装

原文首发:http://coderzhang.xyz

项目中涉及到ObjC与JavaScript交互,于是封装了一个简单的XBWebBridge.

github链接:XBWebBridge

使用方法

• 1.导入JavaScriptCore.framework

• 2.导入XBWebBridge.h

• 3.创建XBWebBridge对象

    self.bridge = [[XBWebBridge alloc]initWithWebView:self.webView];
  

• 4.注册给JS调用的方法(JS中通过注册使用的方法名调用ObjC):

    [self.bridge registerObjcFunctionforJavaScriptWithFunctionName:@"liveCallHanlder"];
    [self.bridge registerObjcFunctionforJavaScriptWithFunctionName:@"liveAjax"];
  

• 5.处理JS传递到ObjC的参数:

    __weak typeof(self) weakSelf = self;
    self.bridge.handleResultDictionary = ^(NSDictionary *result,NSString *registerFunctionName){
    if ([registerFunctionName isEqualToString:@"liveCallHanlder"]) {
        NSLog(@"liveCallHanlder === %@",result);
    }else{
        NSLog(@"liveAjax === %@",result);
    }
    weakSelf.callBack = result[@"callBack"];
  

  };

• 6.Objc调用JS方法:

    NSDictionary *param = @{
                        @"name":@"lilei",
                        @"age":@"13",
                        @"sex":@"1",
                        @"friends":@[@"han",@"li"]
                        
                        };
    [self.bridge callJavaScriptWithFunctionName:self.callBack param:param];
