3 IOS Homescreen Web App tips

Hi,

Clear cache of a homescreen web app

Quick tip for something i forgot and spend hours on. Maybe this will help other people. I feel a bit stupid for not doing this earlier.

If you are making a responsive website and at some point add it to your homescreen, you may run into the same issue i did. Its that you keep updating the website and want to check later on how its going but cant refresh, because you are using it with:

<meta name="apple-mobile-web-app-capable" content="yes">

It looks so pretty but how can you clear the cache, deleting the web app doesnt work.

  • Connect the phone to the Mac.
  • Make sure on your phone its set to Settings->Safari->Advanced->Web inspector->On
  • Open the web app from the homescreen
  • On you Mac OSX Safari, go to the tab Develop->Your iPhone->Your Site
  • Hit CMD+R in the console. That should refresh the web app and clear the cache.

White status bar with black text

Add this to your head

<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent">

On runtime or load, add this.

if(window.navigator.standalone) {
    $("meta[name='apple-mobile-web-app-status-bar-style']").remove();
    $('html').addClass('webapp');
}

You might want to add the webapp class thingy as well so you know when its in that view as you need to add pixels to your header in order to not get behind the status bar.

Boilerplate Meta setup

This is a general setup i have used and is quite handy.

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no, minimal-ui">
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent">

<meta name="apple-mobile-web-app-title" content="My App">

Yep, IOS 8 broke them. Also the password field cant be forced to numeric keyboard anymore either..

When you say iOS 8 broke them, are you referring to the "apple-touch-startup-image"? I cannot find adequate documentation anywhere as to why the "apple-touch-startup-image" is failing now. Do you have a source on this?

thank you so much!! Tip #1 saved me hours.

Works on IOS7 but....most people are not going to have the developer tab enabled on safari so you should explain about going to Safari preferences and enabling that first.
