This is what I’m trying to do
ionViewWillEnter() {
this.events.subscribe('new-data', this.doStuff)
}
ionViewWillLeave() {
this.events.unsubscribe('new-data', this.doStuff)
}
doStuff() {
this.data = this.dataProvider.get(); // error here - 'this' is undefined
}
Error: Uncaught (in promise): TypeError: Cannot read property ‘dataProvider’ of undefined
How can I access this class from my event handler function?
(If I use arrow function, instead of passing this.doStuff, then it there is no error, but I cannot unsubscribe)
