Is there is any way to get a list of installed browsers (such as Safari and Chrome) on iOS devices?
In my app, I want to allow user open a web pages using pre-set browser. It should not interfere to default behavior of iOS
Only if the browser has it's own URL scheme will you be able to open a specific browsers.
There is no way in the current SDK to get al list of registered URL schemes, thus you will have to check wether the scheme is supported your self, by calling the [UIApplication canOpenURL:(NSURL *)URL] method.
I'm not aware of any implementation of browser specific URL scheme's
Call [UIApplication openURL:someURL] with a http: scheme will always open safari, custom browser aren't able to override the http: scheme.

Attempting to load the Facebook MessengerExtensions appears not to work when using the in-browser experience for Facebook messenger (as opposed to the native apps on iOS or Android). When I interact with my bot's persistent menu to open a webview (that is trying to use MessengerExtensions), I get this error in the browser console of a newly opened tab:
Messenger Extensions are not enabled - could be "messenger_extensions" was not set on a url, the domain was not whitelisted or this is an outdated version of Messenger client
I have the impression that MessengerExtensions is simply not supported for the in-browser experience but have a couple of questions:
Can someone find where in the docs this lack of support is stated (because I've obviously missed it if it's there...)?
If this is supported somehow, suggestions for what I might be doing wrong? (I have confirmed that my persistent menu button has messenger_extensions: true and my web_url is whitelisted...)
Is there some kind of workaround (not using MessengerExtensions) for the webview opened in the browser to get the page-scoped user Id (PSUID) for the user interacting with the bot?
For a button generated with the Send API I could conceivably append the PSUID to the URL being opened as a query param (not sure of security considerations on that)
For the persistent menu the web_url of the button action is NOT dynamic (it's configured ahead of time) so I'm unsure how this URL when opened from the browser-based messenger interface is supposed to figure out what user opened it. Thoughts/Ideas?
I've just tried it on the chrome with facebook api version 2.10, and it works. When I clicked on the button, I got a "lightbox" looking window that opened on top of the messenger, and all the proper callbacks are called in javascript.
this is my button json:
{
type: 'web_url',
title: <title>,
url: <url>,
messenger_extensions: true,
fallback_url: <url>,
webview_height_ratio: 'tall'
}
these are a few things that I did:
the button spec should contain messenger_extensions: true
facebook whitelisted_domains doesn't do subdomains, so make sure you whitelist the entire url before the parameters.
fallback_url should be whitelisted as well.
I am struggling a little bit. I have a common url like www.domain.com/test.html
and i want Android users to get my app open if "test" is included, otherwise if they don't have the app their should be directed to the play store. I got everything implemented and it works with mozilla browser. But using chrome on Android it should be forbidden to automatically open the app if it is available!?. Now if the user enters www.domain.com/test.html and i recognize he is using Android and Chrome i tried the intent stuff in a script in a redirected www.domain.com/android_chrome.html:
<script> window.open("intent://scan/#Intent;scheme=zxing;package=com.google.zxing.client.android;S.browser_fallback_url=http%3A%2F%2Fzxing.org;end","_self")
</script>
But the App won't open automatically. If i use a regular Link:
Take a QR code
it works. But i want to let it open automatically!
Google restricted starting intents from javascript apps, that's why it isn't working. Security reasons I guess. You should just display nice big link to let user switch to your app instead of website - or let him continue if he doesn't want to launch the app.
Forcing users into using app is bad, IMO. Splash screen suggesting to use it is okay, but don't push it.
I'm Developing an App using Phonegap, target Devices are Android or iOS driven. My Problem is, that on the iPhone I can only set the "open all whitelist urls in webview" parameter to true or false. So that is the Problem:
Expected Result:
- All links (like www.google.com, www.stackoverflow.com) should open in the Browser
- An embedded iFrame with a Youtube Video should open in the Webview
Result with "OpenAllWhitelistUrlsInWebview" Set to true
- All links and iFrames will open in the Webview
Result with "OpenAllWhitelistUrlsInWebview" Set to false
- No links and iFrames will open in the Webview
How can i specify which links should open in the Browser and which shouldnt? When i remove an url from the whitelist the link won't open at all and also setting target="_blank" wont work properly. Trying it with window.open didn't work either.
Thank you very much for every idea.
Implemented this over the weekend, and it's working great:

This will allow you to set up your plist for the youtube video, while using the above method to open specified links in the external browser.
I'm not sure what/if you need to do anything in Android.
I would like to get a glimpse of web-sites created for iPhone devices. In order to be able to view those sites I have to modify the User-agent header in the HTTP request that my browser sends. That way I can trick the web-server into believing that my browser is an iPhone browser, and then the web-server would send my the iPhone version of the web-site.
So, how can I modify the User-agent header that my browser sends in each HTTP request.
Maybe there is an Firefox plug-in that allows modifying request headers?
Also, I think I heard that Safari allows that somehow....
You can try the user-agent switcher plugin.
Yeah you can do this with Modify Headers add-on for Firefox.
First, there's the following plugin: https://addons.mozilla.org/en-US/firefox/addon/59/
Also, there's Firefox configuration: type "about:config" as URL in Firefox, find general.useragent.* properties there.
You don't need a browser add-on in order to add a custom User-Agent string in your HTTP header. Chrome has added this feature to developer tools.
Open the developer tools and click on the Toggle Device Toolbar option or press cmd+shift+M to open it. You can select a device user agent from the presets or you can also define a custom device like mentioned in the below screenshot.
I have an app that uses OAuth to authenticate, which means the user must be directed to the website to authorize the application. I prefer to make it obvious to the user that they are using a standard browser to authorize at the original site rather than just using a web view to show the content within my app. However, every time they are directed to Safari (via openURL), it launches a new Safari window and once Safari has 8 windows open, it simply fails to work at all.
I'm wondering if there is an equivalen to the "target" attribute of an anchor tag in html which would allow me to cause all openURL calls from my application to open in the same window.
There is other functionality that I can expose via the web application, creating a hybrid app between native iphone functionality and web app functionality in Safari, but if I have to launch a new window every time I switch between the app and Safari, it becomes unworkable. The Youtube app is obviously able to return the user to the previous page after showing a video, but that might well be a custom plugin in Safari for iphone. Also, while returning to the previous page is somewhat useful, sending them to a new URL in the existing window really opens up a lot of possiblities.
I'm pretty sure there is no way to pass a target parameter to openURL:.
What I noticed about Safari is that it won't open another tab if the page you are opening with openURL: is/was already open in Safari. It just reloads that page. This might sound trivial and not helpful but perhaps you could use it to your advantage if you can make your web application only use one page. Different views or states could be expressed with #anchor tags.
An example is http://m.flickr.com. Notice their URL structure? It goes http://m.flickr.com/#/home, http://m.flickr.com/#/explore/interesting/, http://m.flickr.com/#/search and so on. All of these are different web pages to the user but to Safari it's all the same page.
I found iOS 6.0.1 Safari will open the same tab with a simple hashtag, without the slashes. So with the above example http://m.flickr.com, openURL to http://m.flickr.com#someinfo opens to the same tab.
In your webpage, use window.location.hash to return the params. In the above example it will return #someinfo.
