其中callBack是通过这个JSExport实现的
@protocol WebViewJSExport <JSExport>
JSExportAs
(callBack /** callBack 作为js方法的别名 */,
- (void)awakeOC:(InterActionOcType)type param:(NSDictionary *)param
);
@end
WKWebView+WKScriptMessageHandler方式
导入WebKit.framework,并导入我的扩展类#import "WKWebView+Interaction.h"。
使用方式
OC调JS:
[self.wkWebView InterActionToJs:@"JSReloadTitle('你点了刷新JS按钮,我没猜错!')"];
JS调OC:
//注册交互类型
[self.wkWebView registerScriptTypes:@{@"OCDismiss" : @(WKInterActionOcType_dismiss),
@"OCShowAlert" : @(WKInterActionOcType_alert)}];
[self.wkWebView InterActionToOc:^(WKInterActionOcType functionType, NSDictionary *param) {
switch (functionType) {
case WKInterActionOcType_dismiss:
{
BOOL isAnimate = [param[@"animate"] boolValue];
[self dismissViewControllerAnimated:isAnimate completion:nil];
}
break;
case WKInterActionOcType_alert:
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"JS去做平方" message:nil delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
}
break;
default:
break;
}
}];
添加动作
//自定义添加功能类型
typedef NS_ENUM(NSUInteger, WKInterActionOcType) {
WKInterActionOcType_alert = 0,
WKInterActionOcType_dismiss,
WKInterActionOcType_xxxxxxx, //有啥需求就和这里添加
};
并且对应的html中添加JS,参数封装为字典形式。例:
//js调oc
function myDismiss() {
window.webkit.messageHandlers.OCDismiss.postMessage({"animate" : 1}); //这里的OCDismiss对应注册类型
}
其中callBack是通过WKScriptMessageHandler实现的
- (void)userContentController:(WKUserContentController *)userContentController didReceiveScriptMessage:(WKScriptMessage *)message {
dispatch_async(dispatch_get_main_queue(), ^{
NSString *name = message.name;
NSDictionary *value = message.body;
WKInterActionOcType type = [self.typeDict[name] integerValue];
if (self.block) {
self.block(type, value);
}
});
}
