Hi everyone, im following this tutorial on youtube: https://www.youtube.com/playlist?list=PLYxzS__5yYQnpK36-GJjm7IEAuHR7IExa
But on #4 its giving me an error that i cannot figure out how to fix it, because it seems that everything is ok, but the problem is at the time to go to some page (register and login pages) it gives me the error “cannot get /page” and when i click on a “upload” tab it gives me the error from above… where is the place that i should take a look to make it works? thank you so much

Regards

We are working on an app using ionic 3. We are facing the problem of stacking of pages in our app. Could some one tell how to remove this issue. If we open a page a single time then we can revert back to home page in a single time but if we open any page multiple times then we have to revert back the same number times to get back to home page.

Hi, iam using cordova nfc plugin in my app, to read nfc tag, then i check if it is correct on the server and i navigate to next page, or activate reader again.My code in service(userService) looks like this:

public startReading(){
        return new Promise((resolve,reject)=>{
            nfc.readerMode(nfc.FLAG_READER_NFC_A,(tag)=>{
                nfc.disableReaderMode();
                resolve(this.transformTag(tag.id));
            },err=>{
                console.log(err);
                nfc.disableReaderMode();
                reject(err);
            });
        });
    }

and in my page i use it like this:

ionViewWillEnter(){
    console.log("nfcAktivaceLogin");
    this.platform.ready().then(()=>{
      this.userService.startReading().then((tagId)=>{
        console.log("tagid",tagId);
        this.uisLogin(tagId);
      });
    })
  }

uisLogin(tagID){
    let loading=this.loadingCtrl.create({
      spinner:'crescent'
    });
    loading.present();
    this.productService.loginEmployee(tagID).subscribe((data)=>{
      console.log("Výsledek",data);
      loading.dismiss();
      this.navCtrl.push(HomePage);
    }, err=>{
      loading.dismiss();
      this.userService.startReading().then((tagId)=>{
        console.log("tagid",tagId);
        this.uisLogin(tagId);
      });
      let alert = this.alertCtrl.create({
        title: err.message,
        buttons: ['OK']
      });
      alert.present();
    });
  }

In uisLogin Method, iam calling itself inside it, is it a problem? I kinda think that it isnt the best solution, but it seems to be working. Any ideas?

Is it possible to import pages(from src/pages your generate) into Slides? I generated a few pages, and I edited the HTML and .ts files for something. I would like to import those pages into ion-slides since the HTML and .ts files of those pages are lengthy and doing all the slides in one page seems a little disorganized.

something like

<ion-slides>
      <ion-slide>
            {{import page 1 here}}?
       </ion-slide>

       <ion-slide>

One of our app uses some large libraries like three.js, moment etc and it all gets compiled as one large vendor.js which has all the node_modules packed together. And this massive .js is loaded at app launch (at least with v3, I wonder if this changed with v4).

Is there a way import these large libraries such that they are lazy loaded when needed - which in our case will be right after the first page is displayed and becomes interactive. A solution that works with either v3 or v4 will help.

I’m writing an app for both iOS and Android.

On Android, when the user reaches the bottom of the page, the scrolling stops. On iOS, when the user reaches the bottom of the page it “bounces” past the end of the page and shows a white background. I don’t want it to do this - the background of my page is dark grey, and this overscroll looks terrible.

I’ve already added the following three lines to the config.xml file:

<preference name="webviewbounce" value="false" />
<preference name="UIWebViewBounce" value="false" />
<preference name="DisallowOverscroll" value="true" />

But they don’t have any effect.

What else can I do to prevent this over-scroll, “bounce” effect?

I am doing ionic-angular from last few weeks ,and now I have a requirement ,dynamically style public site .The site admin set various color codes and logo image from admin in database and these will reflect when the Public Site opens .

As I am from asp.net background ,previously what is do is,on master page load take values from DB and write into a .less file ,and less java-script library take care of it, its simple there.

But for current situation I am using sass and not able find a way how to write variables value into .scss file .

I just learn a new thing APP_INITIALIZER from here ,but ultimately this post not showing how to write in the .scss file.

I am actually thinking this with my asp.net knowledge,but may be I am wrong ,or there are another way of implementation.

I want a simple solution ,what we do in asp.net I want to achieve this in same way.

Take variable value from DB via api,when application loading for first time.

Write values in SASS variable file .

After that SASS will take care of this and we get result as expected .

Please give some suggestion or example ,to start with .

Thanks.

So, so close to being able to test my app on an Apple device.

I’ve signed up for Apple Developer to get the certificate and provisioning.
I’ve signed up for AppFlow to load all that stuff in and generate the build
I have downloaded the .ipa file to my Windows 10 laptop.

Now, how do I install and run it on my iPhone 6? From the command line I’ve tried “ionic cordova run ios” but it says “Error: xcodebuild was not found. Please install version 7.0.0 or greater from App Store”. How to I make it install the existing .ipa file that’s in the project folder instead of trying to build it fresh?

Hi there,

Is using ThreeJS in Ionic4 possible?
I see that Ionic4 now only supports TypeScript and ThreeJS is javascript based library.

Do you think I can import ThreeJS and use it in a .js file to implement a ThreeJS scene and render within Ionic4??

Does anybody has tried it before?

Hi,

What do you do?

When making a mobile app (Ionic 3 or 4), when should one use Ionic/native storage, and when should one use Firebase? Or do people just use Firebase (real time database, or Firestore, or cloud hosting) for all the storage and ignore local and Ionic storage?

Thanks

Good day, I’m new in Ionic, I have a form in my ionic project that has 2 dropdown menus of selection ion-select. When the user selects an option in the first dropdown menu, it generates the options in the second dropdown list. This works well. when I add new fields, I can reestablish the values of the first list displayed with [(ngModel)] = null in .ts, but I have not been able to reestablish those in the 2 drop-down list.

Last time I submitted my app to iTunes Connect I’ve got this email from Apple:

SDK Version Issue - This app was built with the iOS 11.2 SDK. Starting March 2019, all iOS apps submitted to the App Store must be built with the iOS 12.1 SDK or later, included in Xcode 10.1 or later.

On the other side, Ionic documentation clearly states::

We recommend using XCode 9. Xcode 10 support in Cordova is still a work-in-progress. See this issue for details.

Any recommendations how to solve this and build Ionic app with iOS 12.1?

And more general question: how do you know what iOS SDK you’re currently using and how to change it? I did some research to find answers to these questions, but didn’t find any.

Appreciate your help.

when the button becomes enabled (disableButton() returns false due some change in the page), the DOM is modified correctly by angular, but the button appearance is still disabled. And if I move the mouse over the button then it becomes really enabled! It’s happening on Chrome and Android, but not on Firefox!
Any ideas?
