离子 - 错误：未捕获（在承诺中）：找不到removeView

Question

我的Ionic应用程序工作正常，我还没有做任何事情，但突然间我收到了这个错误，我不知道为什么。

  

＆＃34;错误：未捕获（在承诺中）：找不到removeView

Answer 1

删除组件不是任何问题的解决方案。

问题原因： 有多次调用来解除加载组件的方法。

<强>解决方案： 在创建加载器时，检查加载器实例是否不 已存在，然后再创建另一个实例。

同样，在解除加载器时，检查加载器实例是否存在，然后才解除它。

<强>代码：

constructor(private _loadingCtrl: LoadingController){}

loading;

showLoading() {
    if(!this.loading){
        this.loading = this._loadingCtrl.create({
            content: 'Please Wait...'
        });
        this.loading.present();
    }
}

dismissLoading(){
    if(this.loading){
        this.loading.dismiss();
        this.loading = null;
    }
}

Answer 2

如果您想手动关闭离子加载，可能需要按照以下示例进行操作。我在离子实验室测试过的工作正常。

add_action( 'admin_menu', 'gas_payment_menu' );

function gas_payment_menu()
 {
add_menu_page("Custom Registration", "Custom Registration", 0, "farmers_payment", "farmers_payment");
 }

function farmers_payment()

 { 
 echo "please use this short code for Registration Page [cr_custom_registration]";
 }


 add_shortcode( 'cr_custom_registration', 'custom_registration_shortcode' ); 
function custom_registration_shortcode() {
    ob_start();

<强> 注意：的 如果你手动调用this.loading.dismiss（），我不建议使用dismissOnPageChange，你可能会解雇相同的加载两次。

为什么以下解决方案有效？

我认为Ionic 3+ 是一种异步方法，因此当this.loading.present()仍在运行时，我们无法手动调用this.loading.dismiss()。

因此，如果我们需要手动关闭，我们需要确保已经存在加载并且有一个视图来解除它，我们应该在this.loading.present()之后使用其他方法，如下面的代码。

但是，我不确定为什么我们在旧框架版本（2.0.3）中没有遇到此问题。

present().then

Reference Link，因此只发布了有用的工作提示和代码。

我希望这有帮助！

Answer 3

我设法通过从我的组件中删除LoadingController来解决它。

Answer 4

我删除了loading.dismiss函数并解决了它。

Answer 5

它表示你在load.presenet（）结束之前调用了load.dismiss（）。 你应该试试

let a = this.loadingCtrl.create({content : 'hello world'})
await a.present();
..
.. // your code goes here..
...
a.dismiss()

Answer 6

这是一个用于alertController，但工作方式非常相似。

logout() {
  let prompt = this.alertCtrl.create({
    title: 'Logout',
    subTitle: 'Are You Sure You Want To Logout?',
    buttons: [
      {
        text: 'No',
        handler: data => {
          let navTransition = prompt.dismiss();
           navTransition.then(() => {
             this.navCtrl.pop();
           });
         return false;
       }

     },
     {
       text: 'Yes',
       handler: data => {
         this.lgout();
       }
     }
   ]
  });
 prompt.present();
}

Answer 7

以下是此问题的最简单解决方案：

我在实施 LoadingController

时遇到了这个问题

注意：不要在构造中初始化加载器（它只能在第一次工作，第二次你会遇到删除视图未找到问题）

loading:any;

this.loading=this.loadingCtrl.create({
        spinner:'bubbles',
        content:`Please wait..`
      });

我在从服务器获取数据时显示加载程序 以下是工作代码

 gosignup(number:string){

    this.loading.present();//showing the loader
    //calling webservice 
    this.Authprovider.smsverify(number).subscribe(
      data=>{                  
        this.loading.dismiss();//to dismiss loader        
        if(data.json().msg=="success"){
           this.navCtrl.push(SignupPage,{
             user:this.Usersignup
           })
        }

        if(data.json().msg=="error"){
          this.showToastWithCloseButton("Invalid otp");
        }

      },

      err=>{
          this.loading.dismiss();
          this.showToast("Please try again later");
      },

      ()=>{
              this.loading.dismiss();//to dismiss loader
      }

      );



  }

希望它能解决SO问题

Answer 8

对我来说，问题是我有

dismissOnPageChange: true

当我创建loadingCtrl。

.dissent（）在.present（）之后很快被调用（在本地测试期间，api响应非常快）并且似乎有该参数导致了问题。删除它解决了它。

Answer 9

请尝试下面对我有用的

import { App } from 'ionic-angular';
export class PopoverPage {
   constructor(public navCtrl: NavController
     , public viewCtrl: ViewController
    , public appCtrl: App) {
         this.viewCtrl.dismiss().then(()=>{
          setTimeout(()=>{
            confirm.dismiss().then(()=>{
              this.appCtrl.getRootNav().setRoot('DashboardPage');
            })
          },300)
        })
    }
 }

我已更新到最新版本@ ionic / app-scripts 3.3.0，这也在我的应用程序中发生。
