如何在ionic3和angular5中翻译Toast消息

Question

我想在TS中翻译吐司消息。

Angular ngx-translate usage in typescript 我指的是答案，

message: this.translate.instant('HOME.SCAN ENABLE')

AND

setTimeout(this.setStatus.bind(this), 5000, this.translate.instant('HOME.SCAN COMPLETED')) 

翻译成功

但是

this.setStatus(this.translate.instant('HOME.SCAN MESSAGE'));

翻译失败 出现HOME.SCAN MESSAGE

这是我的家。

scan(){
  this.setStatus(this.translate.instant('HOME.SCAN MESSAGE'));
    this.devices = [];  
    this.ble.scan([Emm_SERVICE], 5).subscribe(  
      device => this.onDeviceDiscovered(device),  
      error => this.scanError(error)
    );

   setTimeout(this.setStatus.bind(this), 5000, this.translate.instant('HOME.SCAN COMPLETED'));
  }

scanError(error) {
    this.setStatus('Error ' + error);
    let toast = this.toastCtrl.create({
      message: this.translate.instant('HOME.SCAN ENABLE'),
      position: 'middle',
      duration: 5000
    });
    toast.present();
  }

  setStatus(message) {
    console.log(message);
    this.ngZone.run(() => {
      this.statusMessage = message;
    });
  }
