例子

准备Toast插件,提示用,用户体验好点,不是必须要装

cordova plugin add cordova-plugin-x-toast

示例:

.run(function ($ionicPlatform, $rootScope, $location, $timeout, $ionicHistory, $cordovaToast) {
	//双击退出
    $ionicPlatform.registerBackButtonAction(function (e) {
      //判断处于哪个页面时双击退出
      //if ($location.path() == '/app/projects' || $location.path() == '/app/plans') {
      if($state.includes('app.*'))
        if ($rootScope.backButtonPressedOnceToExit) {
          ionic.Platform.exitApp();
        } else {
          $rootScope.backButtonPressedOnceToExit = true;
          $cordovaToast.showShortTop('再按一次退出系统');
          setTimeout(function () {
            $rootScope.backButtonPressedOnceToExit = false;
          }, 2000);
        }
      }else if ($ionicHistory.backView()) {
        $ionicHistory.goBack();
      } else {
        $rootScope.backButtonPressedOnceToExit = true;
        $cordovaToast.showShortTop('再按一次退出系统');
        setTimeout(function () {
          $rootScope.backButtonPressedOnceToExit = false;
        }, 2000);
      }
      e.preventDefault();
      return false;
    }, 101);
}
