Ios-header no change backgroundcolor

How i can change de ios-header background color?

If I understand correctly, you are referring to the region with the cell strength, battery level, etc? That can be set using the StatusBar Plugin. See the Ionic Native docs as how to do that:

I have tag in app.
For android it´s render like:
<ion-header _ngcontent-c6="" class="md header-md hydrated"> ... and his class is …

ion-header[_ngcontent-c6] {
    background-color: #000000;
    height: 140px;

But in iOS …
<ion-header _ngcontent-c2="" class="ios header-ios hydrated"> his class …

ion-header[_ngcontent-c2] {
    background-color: #000000;
    height: 130px;

no show #000000


In Ionic 4, it is the toolbar component that get the color. See for more details.

The ion-header is just the outer container.
