So having finished an app for a client, I've been asked to alert any users entering their website via iPhone/Safari that there's an app, and to ask the user if he/she would like to download it.
The method I'm using is to simply set window.location to "itms-apps://itunes.com/apps/[appname]". No redirects, straight to the appstore. Ought to work great, at least judging by the absence of people with similar googlable problems, but it seems that every now and then the appstore gives me and some of my co-workers an "app not found" error screen.
Has anyone else encountered this problem? A solution would be delicious.

I am using parse facebook login for new users of my app. Most users are able to use it without a problem and I have successfully tested all Facebook login scenarios. Some users, however, report that when they press the login button they see brief activity indicator and then nothing happens. In code, no error is registered but the user is not brought beyond the login page to the app's initial screen. The problem resolved if the user deletes the app from their Facebook app settings and then tries again. Has anyone else experienced this and/or found a solution? Thanks
Not sure if this ever got resolved for you.
There are multiple possible causes for this of course including your own code. However, we've seen a similar issue with 2 causes / solutions.
UX-wise we detect multiple failed logins (typically with no error code) and then pop a notification telling the user how to solve. Still digging for a code-level solution that'll solve either of these issues permanently (if you found one, please post!) but hope these help & let you know you're not crazy.
Issue #1: User is logged into multiple Facebook accounts from the same device (e.g. a primary account and an org or 2ndary account).
Fix #1: Have user log out of all Facebook instances (app, safari, iOS settings) and then log back in.
Issue #2: User has rejected Facebook permissions.
Fix #2: For iOS, make sure Your App is toggled on in Settings -> Facebook -> Your App
I have my Facebook login process working on desktop and mobile, except for Facebook's inapp mobile browser (ios and now android). The issue is that if you call FB.login(), nothing at all happens. I assume this is because the inapp browser doesn't deal with popups.
I understand that a redirect auth flow circumvents the need for a login/permissions popup, however I have built a web-app, which means it is a pain to deal with storing the users current state at the point of signing in.
Does anyone have any good solutions for this?
Also I have tested many other sites login buttons through the inapp browser, and all of the ones I have tried so far don't work. Facebook has done a great job of breaking a large amount of sign up processes.
As stated in the comments, that seems to be a bug either in the Android FB- App or in the Android 5 WebView component. There is a bug report at facebook, but they are still working on it. The only solution i could find for now is to turn off the internal browser: http://www.androidpit.com/facebook-disable-browser
Because that action has to be taken by the user itself, it's no satisfying solution. Therefore i guess the only thing we can do at the moment is to stay tuned for facebooks fix.
Update
Facebook confirmed this is a bug. They are working on it. Stay tuned...
2nd Update
Facebook rolled out a patch. Works for me now.
My iOS application allows me to login using my own facebook account successfully. But when I send it on test flight to a friend, the app downloads but when he presses connect to Facebook (which works on my simulator and personal device), it won't let him log in. Doesn't even give him the option to, just spits out an error (com.facebook.sdk error 2). What am I missing? What would cause it to work for me, but not for others? I'm just looking for a general answer here because I followed all the facebook tutorials and I can't imagine what kind of thing could be going wrong.
I just figured out the problem. Should have been SUPER obvious, but being new to development I didn't realize I needed to change the sandbox setting to disabled in order to allow others to access facebook through my app.
This error pops up when your app is not authenticated properly.
You need to keep your BundleId the same at all places.
Change your bundleId in the app that you have registered on Facebook as com.asdad.casd instead of < teamId >.com.asdad.casd
I'm using the official FBConnect library for iOS and trying to get it working in my iPad app. Here's what's strange: when my friend logs in using the call to authorize:permissions:delegate, everything works fine: the dialog asks for his authorization to connect to Facebook, the fbDidLogin delegate method gets called, all is well.
However, when I try to login, the dialog never changes. The keyboard is dismissed, the password field is cleared and it just sits there. The issue is the same in both the simulator and on the device.
Here are the things I've checked and triple checked:
My login name and password are correct. If I do put in the wrong password, an "invalid username/password" message appears, and that isn't happening.
The application is not in sandbox mode.
The Application ID is correct (my friend can login without problems).
Some additional information:
Original application was created by my friend.
I created a second FB app and put in the new Application ID
My friend can login with the new Application ID
I can log in to neither.
This appears to suggest that there is something different about my friend's account, rather than the app itself.
We've been banging our heads together on this for a couple of days now. What could be causing this behaviour? Why isn't an error being generated?
Edit: It seems there are a lot of people affected by this, so in the interest of trying to find an answer, I've added a bounty.
There appears to be a server-side problem with Facebook logins as noted here:
http://github.com/facebook/facebook-ios-sdk/issues#issue/95
People have said that if they change their password on Facebook they are subsequently able to log in using the Facebook-iOS-SDK downloaded from github. Obviously that is a poor long-term solution and would be unacceptable in an app released through the App Store. On the bright side, there seem to be reports of similar login problems logging in from apps on other platforms as well.
Update: Facebook has a bug filed on this subject that can be viewed here:

In my iPhone application I have a UIWebview that shows an html page. Inside that page there are links that should lead the user to the iTunes application and the application they tapped on. However, when the user taps on the link it errors out with 'too many redirects'. Looking at it with a packet sniffer I see it just keeps redirecting to the same http://phobos.apple.com/... URL. I even tried changing the link scheme to 'itms://' but that results in a 'Cannot show URL' error. I could solve this problem by trapping the URLRequest and sending openURL: to the UIApplication but the app has already been deployed and I don't want to patch it. I rather do it on the html/js/server side if possible. Anyone have any ideas?
For anyone still searching for this answer, I found that it seems to be a problem on the simulator which doesn't support itms:// URLs (because there's no App Store app). I didn't see the same issue on hardware, where the App Store app opens just fine (in my case this was when testing URLs from AdMob adverts, but it's probably the same for UIWebView).
