是否可以在Ionic2中更改Alert(Ok,Cancel)按钮的颜色？我们可以使用cssClass属性为按钮赋予颜色吗？

.buttonCss{
    button{
        color:#e74c3c !important;
    }
}

上面的代码为Ok和Cancel按钮提供了相同的颜色,如下图所示

但是我需要得到以下结果(两个按钮都是不同的颜色),

任何帮助表示赞赏......!

编辑1:添加showAlert()功能

    showAlert(title, message, yesHandler, noHandler, caller) {
    let alert = this.alertCtrl.create({
        title: title || "Please Confirm",
        message: message,
        cssClass:'buttonCss',
        buttons: [
            {
                text: 'Exit',
                handler: () => yesHandler(caller)
            },
            {
                text: 'Cancel',
                role: 'cancel',
                handler: () => noHandler(caller)
            }
        ]
    });
    alert.present();
}

我使用Ionic2创建了一个聊天应用程序.当我尝试使用生产构建时ionic cordova build android --prod --release,我收到以下错误.
