Question

我的（简单）React Navigation StackNavigator中有一个自定义标题，如下所示：

module.exports.myFunction = function() {
    const myFnEventEmitter = new(require('events').EventEmitter)();
    var job = new CronJob('00 0-59 * * * *', function() {
            var a = 5;
            var b = 2;

            myFnEventEmitter.emit('started', a + b)

        }, function() {},
        true
    );
    return myFnEventEmitter;
}

但这会返回const myFnEventEmitter = Tester.myFunction(); myFnEventEmitter.on('started', data => { console.log("Done!"); console.log(data); req.flash('success', "You have successfully started the software!"); res.render('dashboard'); })

如何将视图的唯一标题传递给自定义标题？

Answer 1

根据文档，您需要navigationOptions作为访问navigation的函数：

navigationOptions: ({ navigation }) => ({
       headerTitle: <GradientHeader title={navigation.state.params.title} />,
    }),
