ExtJs（sencha touch）を使用していますが、良さそうです
Ext.setup({
tabletStartupScreen: 'images/tablet_startup_768x1004.png',
phoneStartupScreen: 'images/phone_startup_320x460.png',
tabletIcon: 'images/tablet_icon_72x72.png',
phoneIcon: 'images/phone_icon_72x72.png',
icon: 'images/icon_72x72.png',
statusBarStyle: 'black',
glossOnIcon: true,
fullscreen: true,
onReady: function() {
var viewport = null;
var metas = document.getElementsByTagName('meta');
for(var i = 0, length = metas.length; i < length; ++i){
var meta = metas[i];
// already Extjs addedMetaTags
if(meta.name == 'viewport'){
viewport = Ext.get(meta);
break;
}
}
if(null == viewport){
viewport = Ext.get(document.createElement('meta'));
}
if(window.navigator.standalone){
// IMPORTANT!!! not set to height=device-height when iphone standalone mode was ignored "scale" settings
viewport.set({
name: 'viewport',
content: 'width=device-width, initial-scale=0.1, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no'
});
} else {
// IMPORTANT!!! set to height=device-height when !standalone mode; behav window.innerHeight = fullscreen size
viewport.set({
name: 'viewport',
content: 'height=device-height, width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no'
});
}
}
});
