    this.id = this.navParams.get('id');
  }

  ionViewDidEnter() {
    this.getMeme();
  }

//TODO ngif para evitar comentarios del creador
  getMeme() {
    const loader = this.loadingCtrl.create({
      content: "Cargando meme..."
    });
    loader.present();
    this.memeProv.verMeme(this.id).subscribe((result) => {

      loadera.dismiss();
    })
  }

  descargar(ruta) {
    const fileTransfer: FileTransferObject = this.transfer.create();
    /*fileTransfer.download(this.ruta, this.file.dataDirectory + ruta + '.png').then((entry) => {
