Pages can then listen to the refresher's various output events. The refresh output event is fired when the user has pulled down far enough to kick off the refreshing process. Once the async operation has completed and the refreshing should end, call complete.
It will not render properly this way. Please use the enabled property instead to display or hide the refresher. By default, Ionic provides the pulling icon and refreshing spinner that looks best for the platform the user is on.
However, you can change the default icon and spinner, along with adding text for each state by adding properties to the child ion-refresher-content component. The ion-refresher component holds the refresh logic. It requires a child component in order to display the content.
Ionic uses ion-refresher-content by default. This component displays the refresher and changes the look depending on the refresher's state. Separating these components allows developers to create their own refresher content components.
Call complete when your async operation has completed. For example, the refreshing state is while the app is performing an asynchronous operation, such as receiving more data from an AJAX request. Once the data has been received, you then call this method to signify that the refreshing has completed and to close the refresher. A number representing how far down the user has pulled. The number 1and anything greater than 1represents that the user has pulled far enough down that when they let go then the refresh will happen.
If the refresher is enabled or not. This should be used in place of an ngIf. Default is true. The maximum distance of the pull until the refresher will automatically go into the refreshing state.
The min distance the user must pull down until the refresher can go into the refreshing state. Default is How many milliseconds it takes the refresher to to snap back to the refreshing state. Emitted when the user lets go and has pulled down far enough, which would be farther than the pullMinthen your refresh hander if fired and the state is updated to refreshing.
From within your refresh handler, you must call the complete method when your async operation has completed. Need help upgrading to Ionic Framework 4. Log in Sign up.Immortal emperor tun ri
So it needs refreshing a page upon removing an item from ionic storage. How can I refresh a particular page? I need to refresh a single page out of twenty pages on my app so navCtrl. If you're going for a list of items, I would suggest displaying them with an ngFor directive.

Reinitializing the navigation stack by setting the root to the same page as it was before is one of those gotchas. In Ionic 3, this caused the root page to get reloaded from scratch. That's not the case in Ionic 4. The root page can be set with a call to NavController::navigateRoot :.
However, this will only initialize home if a different page was set as root before the call. Otherwise, it will simply remove all the other pages from the navigation stack and keep the same instance of home as root.
Neither the constructor nor ngOnInit will get called. If you're porting code from Ionic 3 and you relied on the page being reloaded e. One way to force the root page to reload is to ensure that its route is different. It's an approach similar to the one I used in a previous blogpost to repeat the same page in history multiple times when navigating a hierarchical structure.
A fake parameter can be added to the route to make it unique. Of course, you need to track the value of the parameter in order to change it on each call. If you're already wrapping all navigation calls in a service to make them easier to test, then this service can also hold the state of the parameter:. Incrementing the counter value before each call ensures a unique route every time the root is reset. Don't forget to modify the router configuration accordingly:.
Notice that the root route redirectTo value must also include a the counter in order to match the home route. With this change, the home page will reliably reload on every call of NavigationService::navigateHome.
Even if the method is invoked from that root page itself, it will get reloaded and both its constructor and ngOnInit will get called.
While you might take a different approach if you're writing a new Ionic 4 application, this workaround can be really useful for keeping the behavior the same when upgrading an application from Ionic 3 to Ionic 4. I know it works great in a project I'm working on. Toggle navigation. If you're looking for online one-on-one mentorship on a related topic, you can find me on Codementor.

It provides a pull- to-refresh feature on a content component. The pull-to-refresh feature allows the user to pull or drag a page down to some limit, and then the current page view is automatically got a refresh.

If the number is 0then it displays the user has not pulled down the refresher. If the number is one or greater than 1then it represents that the user has pulled far down the refresher. If the number is less than 1then the content will return in its actual position. Example: This example explains how you can use the refresher progress in the ionic application.

Ben and I spent a good ten minutes each just playing with pulling the view down.
We quickly realized a problem, though: While it was fun, it was not practical.
That means they swipe up quickly and expect the pull to refresh to trigger and update. See the Pen by Ionic ionic on CodePen. So we went back to a regular fixed-time animation, updated the default icons to be something more visually appealing, and moved on.
The next thing we noticed was that most API calls are pretty fast, perhaps too fast. Our refresher would return to the home position as soon as it was told the information requested was received. We have an internal Hacker News app we were using to test this more info on that soon. We were left unsure if an update actually fired. Setting up console logs allows developers to make sure the refresh actually happened.
We decided to force ms of the refreshing spinner animation. To a developer, this may feel misleading. The refresh is already complete, so why are we still showing the animation? A big part of UX is keeping a user in familiar territory and reassuring him or her that the app is working properly. In our updated pull to refresh, if an update takes longer than ms, it will continue to spin until the data is available.
