OC-Js的交互问题

最近空闲，把以前接触到的关于JS与OC之间是如何交互的给大家总结一下，同时附上网页端的代码，让大家看起来轻松明了！

1、iOS端需要处理的事情

先添加javascriptcore.framework的系统库

#import <JavaScriptCore/JavaScriptCore.h>添加头文件

-(void)makeWebView

{

UIWebView *webView = [[UIWebViewalloc]initWithFrame:CGRectMake(0,64,SCREEN_WIDTH,SCREEN_HEIGHT-64)];

webView.delegate=self;

[self.viewaddSubview:webView];

[SVProgressHUDshowWithStatus:@"正在加载中……"maskType:SVProgressHUDMaskTypeBlack];

self.href=[@"http://"stringByAppendingString:self.href];

//准备webView的属性

NSURLRequest *req = [NSURLRequestrequestWithURL:[NSURLURLWithString:self.href]];

[webView loadRequest:req];

webView.scalesPageToFit =YES;//让页面大小适配

JSContext *context = [webViewvalueForKeyPath:@"documentView.webView.mainFrame.javaScriptContext"];

context[@"userToAppointment"] = ^() {

//项目名称、医生名字、预约价格、商品id

NSArray *args = [JSContextcurrentArguments];

AppointOrderViewController * appointOrder = [[AppointOrderViewController alloc]initWithNibName:@"AppointOrderViewController"bundle:nil];

appointOrder.projectName =[NSStringstringWithFormat:@"%@",args[0]];//不转成字符串的话，给控件“Lable”赋值时会为空

appointOrder.appointDoctor = [NSStringstringWithFormat:@"%@",args[1]];

appointOrder.appointPrice =[NSStringstringWithFormat:@"%@",args[2]];

appointOrder.projectID = [NSStringstringWithFormat:@"%@",args[3]];

appointOrder.shopName=[NSStringstringWithFormat:@"%@",args[0]];

[self.navigationControllerpushViewController:appointOrderanimated:YES];

};

context[@"doctorPage"]=^(){

//医生id

NSArray *doctorIdArr = [JSContext currentArguments];

DoctorHomePageViewController * docHomePage = [[DoctorHomePageViewController alloc] initWithNibName:@"DoctorHomePageViewController" bundle:nil];

docHomePage.doctID =doctorIdArr[0];

[self.navigationController pushViewController:docHomePage animated:YES];

};

}

2、网页端的代码

2.1点击网页的按钮调用网页中自己的方法：

2.2在网页调用自己的方法的实现中调用与网页端商定好的OC的方法，并进行传值
