Problem in CSS to build for iOS

ionic-v1
1

Hi, I have a problem when I compile for iOS does not follow the CSS rules as margin-top and padding-top. I’m using the bar-header and bar-subheader, and ion-content using the has-header classes and has-subheader. But this error only occurs when it is built into iOS, but does not occur on Android and Browser.

<ion-view view-title="Example" hide-nav-bar="true">

    <ion-header-bar align-title="center" class="bar bar-header bar-positive" ng-show="select">
        <button class="button bar-header-scopi" ng-click="toggleSelect()">Cancelar</button>
        <h1 class="title font-14">Example</h1>
        <button class="button bar-header-scopi button-right" ng-click="editSelected()">Editar</button>
    </ion-header-bar>

    <div class="bar bar-subheader size-subheader bg-scopi">
        <a class="left" ng-click="toggleSelect()" style="">Selecionar</a>
        <p class="right">Filtro: {{ status(filter.status) }}</p>
    </div>
    <ion-content ion-sticky class="has-header has-subheader">
	<div class="list">
	    <div class="item item-divider">
	        Atualizado <span am-time-ago="loadedAt"></span>
	    </div>
	</div>
    </ion-content>
</ion-view>
