离子2本机联系人插件查找不退出

Question

我正在尝试使用离子2本机查询所有联系人。运行ionic serve命令时出现以下错误。如果有人知道请告诉我，我该如何解决这个问题。谢谢

Typescript Error
Property 'find' does not exist on type 'typeof Contacts'.

home.ts

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { Contacts, Contact, ContactField, ContactName } from '@ionic-native/contacts';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  constructor(public navCtrl: NavController) {

  }
  testFun(){
    Contacts.find(['*']).then((contacts)=>{
      alert(JSON.stringify(contacts[0]));
    })
  }
}

home.html的

<ion-header>
    <ion-navbar>
        <ion-title>
            Ionic Blank
        </ion-title>
    </ion-navbar>
</ion-header>

<ion-content padding>
    <button ion-button full (click)="testFun()">Get Contacts</button>
</ion-content>

Answer 1

Since Ionic 3.x.x, the way you use Native plugin is a little different from Ionic 2.x.x

1. First you need to add Contactin your constructor
2. You need to add the providers Contactin your @Component

So your home.ts should looks like this instead:

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { Contacts, Contact, ContactField, ContactName } from '@ionic-native/contacts';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html',
  providers: [Contacts]
})
export class HomePage {

  constructor(public navCtrl: NavController, private contacts: Contacts) {

  }

  testFun(){
    this.contacts.find(['*']).then((contacts)=>{
      alert(JSON.stringify(contacts[0]));
    })
  }
}

More usage example check the official doc for Ionic 3.x NATIVE doc here http://ionicframework.com/docs/native/contacts/

import { Component } from '@angular/core';
import { NavController, LoadingController, Platform } from 'ionic-angular';
import { SMS } from 'ionic-native';

declare var navigator : any;

你试过这个吗？

Contacts.prototype.find(['*'])
            .then((contacts)=>{
                alert(JSON.stringify(contacts[0]));
            })
            .catch((err) => {
                alert('Error ' + err);
});
