I have created a phonegap ios application. After installing it is working fine. But after rebooting the mobile it got stuck on splash screen. I can't describe my question clearly.
Actually my app is working fine on first time but when i am opening it for second time after closing it, it got stuck in splash screen. Please let me khow what other thing you need to know about this question. Thanks
I had the same issue (stuck on splash screen on 2nd app launch) but it only occurred when the device was plugged into the computer / xcode.
Unplugged it & app opened up second time ok.
There's not really enough information here to answer the problem because there are many things that could create this problem.
Your basic problem is that the root of your application is not resolving.
I would look into the JS on your initial page. Are you saving any information to local storage? Something is different between the first load and the second. What data are you saving on the first load that may persist to the second?

I have written an AR app in xCode (coding newbie), but when I send it off to apple all they receive is a blank/unpopulated AR kit app (ie straight to camera mode).
They have suggested that I am sending a test flight version, and not a full version, and so every time I upload what I believe to be a fully working app taking onboard their comments, they still only see the camera.
This has been going on for months now and both I and they are loosing the will.
Does anybody have any idea how to stop it sending a blank app, and to get it to send what I can see when I test it at my end?
I have tried changing the build number and version number but still no change.
I just do not understand why they are not receiving what I can see.
All help greatly appreciated.
I believe this has resolved my problem - THANK YOU SO SO MUCH!!!! This has been driving me MAD! The hidden delete button next to the build did not help!!!!! THANK YOU Paulw11 !
Once you delete the version you can select the new version..... (it should not be this hard)
I am somewhat new to developing apps for iOS and I have been creating a few demo projects in Xcode. My problem is the following:
I have been following a few tutorials from Udemy.com and I created an app using firebase, the app works fine for about 3-4 days of use. But after more time passes by, the application does not launch on my device or the simulator. I thought I must have done something wrong when I did the tutorials, so I did them again but the same thing happens after 3-4 days of installing the app. They immediately close after I try to launch them. However, they do work if I rebuild the app on my phone or on the simulator. I do not seem to understand why this happens. has anyone else come across this problem? Or is this a normal thing that happens until you upload the app via the app store? Thank you guys, hope someone here knows. Cheers!
in such case you can check your GoogleService-Info.plist file or get idea about what's wrong by check the App terminate reason printed in your output Console.
I have an iPhone app and working fine . But some of(2 or 3) my customers arises a complaint that they are having issue opening the app in the iPhone . They have installed the app and when open the app it just closes out right away. Also tried restarting phone but it still does this.Also tried to delete the app and then reinstall it but this still happens.
Is this any thing i can do in my app to prevent this ? Or how they can solve this problem ?
Is there any more information you could give regarding the nature of the crash? Have you recreated this scenario in Xcode and gotten an error message?
The best I can think to tell you is to look in the app delegate. That is where your app looks first, so there is some kind of uncaught error happening.
Maybe the app is trying to use some piece of data right at launch and it's not there. Maybe you are trying to use something before it is initialized.
Is your app using any 3rd party frameworks right at launch? If so, maybe something changed with the library.
If it is happening on some iPhones and not others, perhaps you are using some framework or function that is not compatible with an older version of iOS.
Perhaps there is something in common among the kind of devices the app crashes on.
Another thought, does your app ask for any permissions? Such as using the user's location. If it does, and there is a spot in your code where you assume you have permission and you don't perhaps that could cause a crash.
Hope this helps.
P.S. just read the comments to your question. They have some good advice. I would try what they are suggesting.
A user has reported that my app suddenly won't launch on their device. They sent me a video, and they launch the app, the launch image screen shows for a split second, but then crashes back to the iOS home screen.
The user tried deleting and reinstalling the app with no benefit.
I use Crashlytics, and am not getting any reports of crashes from them (or any other user- although I've seen them in prior versions so I know it's working correctly). I'm also not seeing any crashes in iTunes connect.
I asked the user to send me any crash reports in the Settings Diagnostics section and they said there are none listed for my app.
I have confirmed that their iOS version is supported by my app. (iOS 8.4).
I'm not sure where to go next, and would appreciate any pointers. Sorry for the vague question but I have posted everything that I know about the situation.
Just wanted to provide some closure on this. The user ended up wiping and restoring their device, and it solved the problem. It seems extreme to me but it was their own suggestion and didn't take them long to do. So I'm not sure what caused this but that's one (albeit brute force) way to fix it.
So I've built this web app game with HTML 5 and javascript (mainly jQuery). It's meant to be used on an iPad in a location where there's no wireless internet (a museum).
I am using a cache.manifest file to cache all the files needed for the game to work. And on my desktop using both Chrome and Safari this works great. I can see all the files listed in the application cache in the debugger and the app runs perfectly without internet connection.
Testing it on the iPad's browser also gave good results. It seems to take a bit longer for the iPad to cache all the files but if you give it enough time the app works in safari on iOS in airplane mode as well.
Now here's the problem. When I install the app to the home screen and launch it from there the app doesn't work. Only the first page will run and when I try to go to the next one it'll fail and tell me I need internet. (The second HTML page is loaded after the map appears and you've chosen hall 1)
I've read that it might need to cache all over again if launched from the home screen so I've tried waiting for it to cache and then going to the next page. I've waited for 2-3 minutes yet it still didn't work.
You can find the app here. It's in Dutch so it might be a little confusing.
The manifest file is here.
Any help would be greatly, greatly appreciated! Thanks.
So I figured it out myself.
Turns out it was a real rookie mistake. I had some bad references to the cache.manifest file in some of the pages of the app. And on an iOS device that seems to cause some problems.
Pretty confusing since it worked fine in a regular browser. But lesson learned: iOS is very picky when it comes to little details and you need to have a reference to the manifest-file on every page.
