Ionic 3 setRoot在iOS设备上不起作用

Question

i am testing a the hello world app on an iPhone4 device and some others devices with Android.

Ionic version 3.10.3

npm version 3.10.10

.

The main huge problem is with the iPhone device, the call to setRoot is not working. ("WORKS on Emulators")

void onGoClick(){
// this line **DOES NOTHING** and no error is thrown.

this.navCtrl.setRoot(HomePage);


// this line **DOES NOTHING** and no error is thrown.

this.app.getRootNav().setRoot(HomePage);

// this line **DOES NOTHING** and no error is thrown.

this.app.getRootNav().setRoot("HomePage");
}

this also DOES NOT WORK

var root = this.appCtrl.getRootNav();
root.popToRoot();
root.setRoot( "HomePage" );

or without quotes root.setRoot( HomePage );

.

but if i click the button twice it works....

is like some refresh is missing....

Regards.

The problem is with the iOS version, 4 is too old, if you test with an iPhone 6.

you can also try to run like this.

 this.navCtrl.setRoot(DestinationPage).then( ()=>{ this.navCtrl.popToRoot().then( ()=> { }).catch(err=>{ TError.handleException( "err 2: ", err ); }); }).catch(err=>{ }); 

Regards.
