Safari ios and ipad zooming in with camera - mobile-safari

Using the getUserMedia() API to use the camera. The problem I have is that it works on everything but iOS and iPad. I can snap a picture but I can't zoom. I saw this post but has no response. I'm looking at caniuse and the capabilities and from what I can tell Safari on both mobile and desktop shows it's supported. Any tips?
if (navigator.mediaDevices && navigator.mediaDevices.getUserMedia) {
navigator.mediaDevices.getUserMedia(videoConstraints)
.then(stream => {
setTimeout((evt) => {
const track = stream.getVideoTracks()[0];
const capabilities = track.getCapabilities();
const settings = track.getSettings();
if (('zoom' in capabilities)) {
alert('zoom exists');
const elemZoom = this.dom.select(`${this.el} #zoom-slider`);
// Map zoom to a slider element.
elemZoom.min = capabilities[`zoom`][`min`];
elemZoom.max = capabilities[`zoom`][`max`];
elemZoom.step = capabilities[`zoom`][`step`];
elemZoom.value = settings[`zoom`];
elemZoom.oninput = (event) => {
track.applyConstraints({
advanced: [{
zoom: event.target.value
}]
});
}
elemZoom.hidden = false;
}
elemVideo.srcObject = stream;
}, 500);
})
.catch(err => {
});

Ionic 4, Firebase-x and FCM Push notification with action buttons

I am trying to add action buttons to the push notifications sent via the firebase admin SDK to my Ionic 4 app using the Firebase-X native plugin to handle push notifications. My app is running on android and ios.
Here's my current script that sends me successfully a push notification:
exports.sendDebugPush = functions.pubsub.schedule('* * * * *').onRun((context) => {
let promises: Promise<any>[] = [];
return admin.database().ref('/users/******').once("value")
.then( user => {
let todos = [];
for(let key in user.val().nextActions) {
if(user.val().nextActions[key].active != false) {
let todo = user.val().nextActions[key]
todo['todoid'] = key;
todos.push(todo);
}
}
if(todos.length > 0) {
//currently we pick a random todo, later on the one with the highest priority
//todos.sort((a, b) => (a.priority/1 < b.priority/1) ? 1 : -1);
let randomTodo = todos[Math.floor(Math.random()*todos.length)]
let payload: any = {
notification: {
title: "Gossik",
body: "Hoiiiii " + new Date().toISOString()
},
data: {
title: "Gossik",
body: "Hoiiiii " + new Date().toISOString(),
target: 'todo',
todoid: randomTodo.todoid
}
};
Object.values(user.val().devices).forEach( (device) => {
promises.push(admin.messaging().sendToDevice(String(device), payload));
});
}
return Promise.all(promises)
.then( () => {
console.log('success!');
})
.catch( error => {
console.log('failed :(');
console.log(error);
});
});
});
Of course, without action buttons. And this function handles the push notifications in my app (this.firebase = FirebaseX plugin imported from 'import { FirebaseX } from "#ionic-native/firebase-x/ngx";'):
initPushNotifications() {
this.firebase.getToken().then(token => {
this.db.saveDeviceToken(this.auth.userid, token);
});
this.firebase.onMessageReceived().subscribe(data => {
if(!data.target) {
let title = '';
if(data.title) {
title = data.title;
} else if(data.notification && data.notification.title) {
title = data.notification.title;
} else if(data.aps && data.aps.alert && data.aps.alert.title) {
title = data.aps.alert.title;
}
let body = '';
if(data.body){
body = data.body;
} else if(data.notification && data.notification.body){
body = data.notification.body;
} else if(data.aps && data.aps.alert && data.aps.alert.body){
body = data.aps.alert.body;
}
this.alertCtrl.create({
message: title + ' ' + body,
buttons: [
{
text: "Ok"
}
]
}).then( alert => {
alert.present();
});
} else {
this.goToToDoPage(data.todoid);
}
});
}
It does this also successfully. I achieved to handle the click on the push notification such that it redirects to my To-Do page for this kind of push notification (one with a 'target' property). But now I'd like to add two action buttons 'Start' and 'Skip' on the push notification to start or skip the corresponding to-do. To be clear, I am talking about a background push notification, so the app is not open. The user then gets a standard push notification on his phone and there I'd like two action buttons to take an action without opening the app itself.
I tried various things with the payload to first even show me action buttons, but didn't achieve it. For example, the following is not working for me:
let payload: any = {
notification: {
title: "Gossik",
body: "Hoiiiii " + new Date().toISOString()
},
data: {
title: "Gossik",
body: "Hoiiiii " + new Date().toISOString(),
target: 'todo',
todoid: randomTodo.todoid,
"actions": [
{ "icon": "approve_icon", "title": "APPROVE", "callback": "AppComponent.approve", "foreground": true},
{ "icon": "reject_icon", "title": "REJECT", "callback": "AppComponent.reject", "foreground": true}
]
}
};
Thanks a lot in advance for your help and let me know if something is still unclear. :)

Integrate the pull to refresh feature in Ionic 3 with Wordpress

I'm working on a Ionic3 app integrated with Wordpress using REST API v2 and I need to include the pull to refresh feature but I don't understand how to do it with my code.
This is my function that retrieves my post
getPostsWordpress(){
if(!(this.posts.length > 0)){
let loading = this.loadingCtrl.create();
loading.present();
this.wordpressService.getRecentPostsWithSort(this.categoryId,this.sort)
.subscribe(data => {
for(let post of data){
post.excerpt.rendered = post.excerpt.rendered.split('<a')[0] + "</p>";
this.posts.push(post);
}
loading.dismiss();
});
}
}
...
doInfinite(infiniteScroll) {
let page = (Math.ceil(this.posts.length/10)) + 1;
console.log("PAGE_"+page)
console.log("this.posts.length_"+this.posts.length)
let loading = true;
this.wordpressService.getRecentPostsWithSort(this.categoryId,this.sort, page)
.subscribe(data => {
for(let post of data){
if(!loading){
infiniteScroll.complete();
}
post.excerpt.rendered = post.excerpt.rendered.split('<a')[0] + "</p>";
this.posts.push(post);
loading = false;
}
}, err => {
this.morePagesAvailable = false;
})
}
doInfinite let me to implement infinite scroll, and all works well!
How is it possibile to integrate pull to refresh from the ionic documentation?
This is a sample from the doc and I don't understand how could I use it in my project.
doRefresh(refresher) {
console.log('Begin async operation', refresher);
setTimeout(() => {
console.log('Async operation has ended');
refresher.complete();
}, 2000);
}
Someone can help me?
Thank you in advance!
add this to ur html
<ion-refresher (ionRefresh)="doRefresh($event)">
<ion-refresher-content
pullingIcon="arrow-dropdown"
pullingText="Pull to refresh"
refreshingSpinner="circles"
refreshingText="Refreshing...">
</ion-refresher-content>
then in ur do refresh
doRefresh(refresher) {
console.log('Begin async operation', refresher);
//ur function e.g getPostWordPress()
setTimeout(() => {
console.log('Async operation has ended');
refresher.complete();
}, 2000);}

Scrolling only side menu div and others should be fixed when menu is open

I have a side menu and when it's open, the body can be partially seen. My side menu might be long so you could scroll on it. But when the menu is at the bottom you then scroll on the body, and I don't want this behaviour.
Similar to Scrolling only content div, others should be fixed but I'm using React. Other content should be scrollable when my side menu is closed. Think of the content as side menu in the example in the link. So far I'm using the same technique provided by that answer but it's ugly (kinda jQuery):
preventOverflow = (menuOpen) => { // this is called when side menu is toggled
const body = document.getElementsByTagName('body')[0]; // this should be fixed when side menu is open
if (menuOpen) {
body.className += ' overflow-hidden';
} else {
body.className = body.className.replace(' overflow-hidden', '');
}
}
// css
.overflow-hidden {
overflow-y: hidden;
}
What should I do with Reactjs?
You should make a meta component in react to change things on the body as well as changing things like document title and things like that. I made one a while ago to do that for me. I'll add it here.
Usage
render() {
return (
<div>

This component could probably be changed a little for your case (withSideEffect is used for both client and server side rendering... if you arent using server side rendering then its probably not completely necessary) but the component will work on client side rendering if you would like to use it there as well.
ReactJS doesn't have direct access to the <body> element, and that's the element that needs to have its overflow-y style changed. So while what you're doing isn't perhaps the prettiest code, it's not entirely wrong either.
The only real suggestion I'd give is (shudder) using inline styles on the body instead of a classname so as to avoid having to introduce the CSS declaration. As long as your menu is the only thing responsible for updating the overflow-y attribute, there's no reason you can't use an inline style on it. Mashing that down with the ?: operator results in fairly simple code:
body.style.overflowY = menuOpen ? "hidden" : "";
And then you can just delete the .overflow-hidden class in its entirety.
If for some reason multiple things are managing the overflow state of the body, you might want to stick with classnames and assign a unique one for each thing managing it, something like this:
if (menuOpen) {
body.className += ' menu-open';
}
else {
// Use some tricks from jQuery to remove the "menu-open" class more elegantly.
var className = " " + body.className + " ";
className = className.replace(" overflow-hidden ", " ").replace(/\s+/, " ");
className = className.substr(1, className.length - 2);
}
CSS:
body.menu-open {
overflow-y: hidden;
}

Rendering from two cameras at the same time in A-Frame

the recent v0.3.0 blog post mentions WebVR 1.0 support allowing "us to have different content on the desktop display than the headset, opening the door for asynchronous gameplay and spectator modes." This is precisely what I'm trying to get working. I'm looking to have one camera in the scene represent the viewpoint of the HMD and a secondary camera represent a spectator of the same scene and render that view to a canvas on the same webpage. 0.3.0 removes the ability to render a-scene to a specific canvas in favor of embedded component. Any thoughts on how to accomplish two cameras rendering a single scene simultaneously?
My intention is to have a the desktop display show what a user is doing from a different perspective. My end goal is to be able to build a mixed reality green screen component.
While there may be a better or cleaner way to do this in the future, I was able to get a second camera rendering by looking at examples of how this is done in the THREE.js world.
I add a component to a non-active camera called spectator. in the init function I set up a new renderer and attach to div outside the scene to create a new canvas. I then call the render method inside the tick() part of the lifecycle.
I have not worked out how to isolate the movement of this camera yet. The default look controls of the 0.3.0 aframe scene still control both camera

I've created a set of components that can help with this. https://github.com/diarmidmackenzie/aframe-multi-camera
Here's an example showing usage with A-Frame 1.2.0 to display the main camera on the left half of the screen, and a secondary camera on the right half.

CSS Transitions iOS 7 Phonegap

I have used toggle switch from this http://proto.io/freebies/onoff/ in my phonegap app.
It's been working fine on android and iOS6, however it's not working on iOS 7 phonegap app.
Does anyone know if there is any problem with CSS transition on iOS7 Webview?
I have changed following code
Switchery.prototype.handleOnchange = function(state) {
var evt = new Event('click');
this.element.dispatchEvent(evt);
if (typeof Event === 'function') {
var event = new Event('change', { cancelable: true });
this.element.dispatchEvent(event);
} else {
this.element.fireEvent('onchange');
}
};
into this
Switchery.prototype.handleOnchange = function(state) {
if ("createEvent" in document) {
var event = document.createEvent("HTMLEvents");
event.initEvent("change", false, true);
} else {
this.element.fireEvent('onchange');
}
};
Also I have commented following lines (multiple of following) in setPosition() function of switchery.js
// this.setSpeed();
