离子段仅在单击内容输入后更改

Question

我正在使用ionicv2和Adobe Creative SDK构建照片编辑应用程序.我已经成功实施了创意SDK.

在CSDK成功返回已编辑文件的URL后,我将包含段的页面与文件URL一起推送.

问题出在第二页,当我点击该段时,它不会切换.只有在我点击页面内的输入时才会切换.

我尝试在没有CSDK的情况下进行操作,它运行没有任何问题.

我的代码:

loadCamera(sourceType){

    const options: CameraOptions = {
      quality: 100,
      destinationType: this.camera.DestinationType.DATA_URL,
      encodingType: this.camera.EncodingType.JPEG,
      mediaType: this.camera.MediaType.PICTURE,
      sourceType: sourceType
    }

    this.camera.getPicture(options).then((imageData) => {

      // imageData is either a base64 encoded string or a file URI
      // If it's base64:
      let base64Image = 'data:image/jpeg;base64,' + imageData;

      var thisModule = this;

      function success(newUrl) {
          console.log("Success Editing!", newUrl);
          thisModule.goToCreate(newUrl);
      }

      function error(error) {
          console.log("Error!", error);
      }

      /* Optional `options` object. See API guide for usage. */
      var options = {
           outputType: CSDKImageEditor.OutputType.JPEG, 
           quality: 70
      };

      /* Launch the Image Editor */
      CSDKImageEditor.edit(success, error, base64Image, options);
    }, (err) => {
    // Handle error
    });

  }

  /* Push a new page along with url */
  goToCreate(url){
    this.nav.push(SecondPage, {url: url});
  }

}

第二页(包含段组件)

section: string;
url: string;

  constructor(...) {
    this.url = navParams.get('url');
    console.log(this.url); //Working Perfectly

    this.section = "segment1";
  }

  onSegmentChanged(segmentButton: SegmentButton) {
    // console.log('Segment changed to', segmentButton.value);
  }

  onSegmentSelected(segmentButton: SegmentButton) {
    // console.log('Segment selected', segmentButton.value);
  }

第二页HTML(当我点击第2段时,它不会去那里,除非我点击段1内的输入)

<ion-content class="secondpage-content">
  <ion-segment class="secondpage-segment" [(ngModel)]="section" (ionChange)="onSegmentChanged($event)">
    <ion-segment-button value="segment1" (ionSelect)="onSegmentSelected($event)">
      Segment 1
    </ion-segment-button>
    <ion-segment-button value="segment2" (ionSelect)="onSegmentSelected($event)">
      Segment 2
    </ion-segment-button>
    <ion-segment-button value="segment3" (ionSelect)="onSegmentSelected($event)">
      Segment 3
    </ion-segment-button>
  </ion-segment>
  <div [ngSwitch]="section">
    <div *ngSwitchCase="'segment1'" >
      <ion-item>
        <ion-label floating>Input</ion-label>
        <ion-input type="text" formControlName="input_example"></ion-input>
      </ion-item>
    </div>
    <div *ngSwitchCase="'segment2'" >
    </div>
    <div *ngSwitchCase="'segment3'" >
    </div>
  </div>
</ion-content>

此外,控制台日志不会返回任何错误.你有什么想法吗？我真的认为它与CSDK有关.谢谢

我在段上遇到了同样的问题。我解决这个问题的方法是：

import { Component, ViewChild } from '@angular/core';
import { IonicPage, NavController, NavParams, Segment, ModalController } from 'ionic-angular';

section: string;
url: string;
@ViewChild(Segment)
private segment: Segment;
constructor(...) {
    this.url = navParams.get('url');
    console.log(this.url); //Working Perfectly

    this.section = "segment1";
    setTimeout(() => {
        if (this.segment) {
            this.segment.ngAfterContentInit();
            this.segment._inputUpdated();
            this.onSegmentChanged(null)
        }
    });
}

onSegmentChanged(segmentButton: SegmentButton) {
    // console.log('Segment changed to', segmentButton.value);
}

onSegmentSelected(segmentButton: SegmentButton) {
    // console.log('Segment selected', segmentButton.value);
}
