How to Use

自定义 JavascriptInterface

• 自定义 JavascriptInterface 类
• 在暴露的接口前添加FM_EXPORT_METHOD宏
• 支持的参数可以是 nil NSNull NSString NSNumber NSDictionary NSArray NSDate char int double BOOL
• 同时支持返回值给Javascrip的回调， 回调的类型FMCallBack，支持参数同上

@implementation JavascriptInterface

FM_EXPORT_METHOD(@selector(push:))
- (void)push:(NSUInteger)one {
  [self.viewController.navigationController
      pushViewController:[WKViewController new]
                animated:YES];
  NSLog(@"test push%ld", (unsigned long)one);
}

FM_EXPORT_METHOD(@selector(pop:))
- (void)pop:(NSString *)testArray {
  [self.viewController.navigationController popViewControllerAnimated:YES];
  NSLog(@"pop array %@", testArray);
}

FM_EXPORT_METHOD(@selector(setNavTitle:response:))
- (void)setNavTitle:(NSDictionary *)userInfo response:(FMCallBack)callBack {
  self.viewController.title = userInfo[@"name"];
  callBack(@{@"name":@"carlSQ",@"age":@"26"});
}

添加接口给javascript调用

用 FMWKWebViewBridge 类中的接口addJavascriptInterface 添加接口道javascrip层

_webViewBridge = [FMWKWebViewBridge wkwebViewBridge:self.webView];
[_webViewBridge addJavascriptInterface:[JavascriptInterface new] withName:@"JavascriptInterface"];

js层调用

FM_Require 中的名字是 addJavascriptInterface 中设置的名字

<script>

var javascriptInterface = FM_Require('JavascriptInterface')

javascriptInterface.setNavTitle({"name" : "carl", age:"18"},function(responseData) {
                                     setNavTitle.innerHTML = "name:"+responseData.name +"  age:" + responseData.age;
                                     })

</script>
