I have several iframe apps that stopped vertical resizing today. Has anyone else noticed an issue? Here is the small excerpt from my code that does the resizing on several apps:
if (appsettings.minheight != "null")
{
FB.XFBML.parse();
FB.Canvas.setSize({ width: '810px', height: appsettings.minheight + "px" });
FB.Canvas.scrollTo(0,0);
}
appsettings.minheight does have a value, and this was working fine recently. From the docs:
Note: this method is only enabled when Canvas Height is set to "Settable (Default: 800px)" in the Developer App.
I double checked this, and the app settings were all set to fluid, but this has been the case for a while. I tried toggling to Fixed (and setting a value) earlier today, but still no luck. I do not have a setting called "Settable."
Thanks,
Tim
Try it without the "px" like in the documentation: FB.Canvas.setSize({ width: 640, height: 480 });

I'm having an issue with textfields in Sencha Touch 2, this is only occurring in iOS 7 and working fine in iOS 6 and Android.
The issue is when you tap a field the keypad opens but the cursor disappears, it should be focus on selected textfield but it does not. You have to tap the textfield again to focus.
I have checked this issue on iOS 6 and android (on devices as well as on simulators), working fine but not on iOS 7 only.
Is anybody having this issue...?
Is this a bug in sencha or should i missing something, please advice.
Thank you..
I have found this to be directly related to two things:
centered: true
pack: 'center'
When I removed those lines, my app started playing nice. The challenge is to find an alternative way to center your panels.
I spent days figuring this out. Actually there is a problem with Sencha understanding the ViewPort height. In your index.html add a script block with the following code
if (window.device && parseFloat(window.device.version) == 7.0) {
document.body.style.paddingTop = "20px";
Ext.Viewport.setHeight(Ext.Viewport.getWindowHeight() - 20);
}
This does two things for you
It Provides enough space on Top to display the activity bar
It sets the Viewport height to be that of screen height, irrespective of the keyboard being present or not.
Also, If your app works in Portrait and Landscape mode, you will need to add these lines in your Viewport.js (or Main.js)
initialize: function(){
Ext.Viewport.on('orientationchange', 'handleOrientationChange', this, {buffer: 0 });
},
handleOrientationChange: function(){
try{
if (parseFloat(window.device.version) == 7.0) {
Ext.Viewport.setHeight(Ext.Viewport.getWindowHeight() - 20);
}else{
Ext.Viewport.setHeight(Ext.Viewport.getWindowHeight());
}
}catch(e){
// do nothing
}
},
And Yes, Make sure they Keyboard Bounce is TRUE in true (if you are using cordova). This will make sure your field does not get hidden.
Hope this works for you.
add height="device-height" in viewport meta tag, fixes the issue.

This has surely been covered countless times, but I cannot find a working solution.
how do you get rid of the scrollbars in a Facebook iframe app in Chrome. Both IE & Firefox are fine.
Using the suggested CSS overflow:hidden, simply cuts off the content if its over 800px in height.
Even the Facebook Coca Cola iframe app has the content cut off!! see here
http://www.facebook.com/cocacola?sk=app_161193133389
this is what is also happening to my app in Chrome (v. 16.0.912.77 m)
add this to your canvas app's fb js:
FB.Canvas.setSize({ width: 520, height: X });
where X is the height you want.
If your app is fluid use:
FB.Canvas.setAutoGrow();
i had a similar issue: after adding FB JS SDK and
FB.Canvas.setAutoGrow();
i had to set
body{}
in css to keep the scroll bars from showing in chrome. In my case is was padding.
body{
overflow: hidden;
margin: 0px;
padding: 0px;
}
I would also try to set the size with a delay and experiment with it a little:
window.setTimeout("FB.Canvas.setSize({ width: 520, height: 1111 })", 2000);
Also don't forget to initialize Facebook with your app id ( FB.init ) before calling FB.Canvas.setSize or FB.Canvas.setAutoGrow.
You have to make a few tweaks to you app. First, add the following code to your page:
FB.Canvas.setAutoGrow(); to tell the Facebook SDK to resize the iframe if the contents is longer.
Add overflow: hidden to the <html> or <body> CSS
Check your app settings and make sure you have set the Canvas Width to 'fluid' and Canvas Height to 'fixed' (Go to Settings > Advanced > Scroll to Canvas Settings.)
All of these things should fix the scroll bars. If it doesn't, using something like "Inspect Element" in Chrome to see if something is causing the bars to appear.
There are various solutions you could try below. Please comment as to which one, or if none of them work and I will update this answer accordingly.
If you haven't already, try adding: body{overflow:hidden;}
You may also have javascript disabled.
Alternatively, you could set the fixed height for the app very high in the app settings, where it says: fixed[ ]. Also make sure that fixed is selected on your app settings.
If this happens on other apps, including that CocaCola page you mentioned, then it could possibly be the browser. Try updating. I use the Chrome 19.0.1084.56 and I have no problems, (except for me the height is always pushed to a 1200px maximum height).
Also look here: 'Choosing between Facebook iframe scrollbar or page cut off halfway' where there is a solution that you can try.
Edit: Also look here: 'Timeline page app height stuck at 800px'.
Edit: After some looking through the Facebook bug area, Facebook say this is not a bug on Facebook's end, therefore must be a problem in your code. (Source: 'https://developers.facebook.com/bugs/360687100649759')
If that doesn't work, then comment and say so and I will do some further research.
CityVille seems to have a version of the FB API that allows them to go 100% width/height within a Facebook iframe. Is this only for them? How can this be achieved?
Thanks!
Have you tried the following javascript ?
FB.Canvas.setSize({ width: 600, height: 880 });
but before that you will need to go to the apps settings under advance tab and change your canvas option
They've finally opened up fluid canvas size to everyone.
OK, so i've been working on an FB app that changes height on every page. I, obviously used the setAutoResize function in my app layout and i have the following:
window.fbAsyncInit = function() {
FB.init({appId: '###', status: true, cookie: true, xfbml: true});
FB.Canvas.setAutoResize();
};
And it works fine in IE, Safari and Chrome but not in FF4. I also used:
window.setTimeout(function() {
FB.Canvas.setSize({height: $('body').height()});
}, 1000);
but no luck either. Does anyone experienced this before? tnx in advance.

An answer has already been provided, but I might as well post my solution to the problem. In Firefox the scrollbars are still part of the iFrame even if your page fits. They just don't have the blue scroller. This adds about 20px.
I don't think that your jQuery solution will work because height() doesn't take into account margin and padding. Maybe try this.
FB.Canvas.setSize({ height: $(document.body).outerHeight(true) + 20, width: 760 });
I added this to my css and it seemed to work (didn't have to muck with my autoresize):
body {
margin-top: -20px;
padding-top: 20px;
}
If you already have padding added to the top of your body, you will likely need to add 20px to it.
I assume it's because firefox measures the body height differently than other browsers.
Tested in ff8, chrome16 and ie9 with no negative repercussions.
This sounds like it might be a bug? Check out:

If this is affecting you vote it up :)
FYI Warning! According to the Facebook Developer Roadmap FB.Canvas.setAutoResize will be renamed to FB.Canvas.setAutoGrow on July 5, 2012.
From the page:
We have renamed FB.Canvas.setAutoResize to FB.Canvas.setAutoGrow so
that the method more accurately represents its function.
FB.Canvas.setAutoResize will stop working on July 5th. We will
completely delete the function on August 1st.
I tried teh jScroll plugin by Kelvin Luck. First of all its a wonderful script. Its working fine with text, ie text as contents, in all browesers. But when we insert images in that the scroll is not working in Safari and Chrome... please help me. Am a beginner in javascrpt...:)
Retheesh
Another way of doing it is to initialise the plugin once the entire page is loaded
$(window).load(function(){
$('.scroll-pane').jScrollPane();
})
Ok, this way late, but I just spent most of the day figuring this out.
It's actually quite simple and also sort of explained in the jScrollpane Demo pages...
Since I am using the Wordpress plugin, using the the workaround Dann provided seemed a bit to complicated. The solution here is setting the image height in your CSS file for this specific page instead of (or on top of) declaring them inline.
So basically if you have
<div id="mydiv">
<img src="...." height=200px"/>
>/div>
jScrollpane won't recognize the height of the pictures and count them for your div height. So you need to add a class to your div and define the img height in your CSS:
#mydiv .newclass img {
height: 200px;
}
and it will work fine!
I had a similar problem.
Reinitialising the panel seemed to work.
I used this script:
$('.image_class').load(function () {
$('.scroll-pane').jScrollPane();
});
Dann
It's a known issue, but Dann's workaround is effective. I ended up testing for the presence of troublesome images, since they weren't always present on the page and affecting the scroll area size:
$(function() {
if($('.image_class').size()) {
$('.image_class').load(function() {
$('.scroll-pane').jScrollPane();
});
} else {
$('.scroll-pane').jScrollPane();
}
});
