EAAccessory protocolstrings issue - iphone

I am trying to connect my iPhone to a custom bluetooth device. And I am following the EAdemo. Running the app, I am not getting null in protocolstrings. Whereas, sometimes I do get the object when I debug the app. Any insight on why this happens?
Could be this a timing problem?
Its being inconsistent...

It was a problem with the device itself. There was no issue with code. Thanks.

How to use swift to detect app crash?

I am currently working on code to log a user's behavior in the app and to report crashes and the sequence leading up to them. I have one big problem, I do not know how to make my app detect if it has crashed. Does anybody know how to do this in swift? Your help would be much appreciated!
I don't think there is currently a way to do this. When your app crashes it ceases to function and all processes stop. Usually any crash and diagnostic data is sent via the user settings panel.
Edit: There is an helpful post here: https://stackoverflow.com/a/8242215/4891259
Hope that helps.

Revmob Ads in IOS Application

I am trying to integrate Revmob Ads in my IPhone Application but after two or three time, i am getting time out message in my console and after it nothing is happening even if i place NSlog in delegate function.
Can any one help me to solve issue of time out?
And i am using Full screen Ads.
thanks
Usually you get no ads due to lack of ads for you device or due to time out on the connection with their server.
If you have no ads for you device you can force to show the ads with Testing mode:
[RevMobAds startSessionWithAppID:#"your AppID"];
[RevMobAds session].testingMode = RevMobAdsTestingModeWithAds;
If your problem is timeouts first you need to check if your internet connection is ok.
This kind of timeouts are a temporary issue and should be gone in minutes, if this problem
persists I recommend to contact revmob.
[RevMobAds startSessionWithAppID:#"Your Id"];
[RevMobAds session].testingMode = RevMobAdsTestingModeWithAds;

Application crahes when loading initially

We have the loaded the app in the itunes but it got rejected because of following issues...
How to overcome the crashing reports while loading initially
This is the message from apple's site...
"Here is how we found this crash: 1) Launch application while connected to cellular or WiFi network connection. 2) Tap on the Find My Location button. 3) Application produces a crash."
can anyone help me out.
Thanks in advance...
Have you followed Apple's advice at all and tried to reproduce the crash? Do that, and check all the methods related to the Find My Location Button. Good things to look for - double releases, nil objects, infinite loops, that you're targeting the right iOS etc. Beyond stating the obvious, no one here can help you until you help us!

What does this error mean: "lo->hi recycling invariant violated!" and what can I do to fix it?

My iPhone app started logging this error:
lo->hi recycling invariant violated!
followed by:
Program received signal: “EXC_BAD_ACCESS”
whenever I launched it on my iPod (3.1.3) and sometimes when I launch it in the simulator.
What does this error mean, and how can I fix it?
I am using cover-flow in my app. I think this might be the problem.
Thanks in advance.
Yes cover flow is the problem. Note that UICoverFlowLayer is private API. If you're targeting for AppStore, consider other alternatives here.
The error "lo->hi recycling invariant violated!" is raised by -[UICoverFlowLayer _updateTick], which should be caused by reusing the wrong sublayer for display. The detail I don't know because there's no detail code, nor I'm familiar with the Cover Flow API.

Unexpected error while trying to connect to iPhone

Your mobile device has encountered an unexpected error(0xE800002E)
Try disconnecting and powering off the device;then power the device on and reconnect it.
I received these message so many times. How can I fix it?
Although you can see this error when you connect in XCode, it is not actually an Xcode defect.
See this thread at Apple's discussion boards. You basically need to reset you phone. I'm not sure but Ithink there may be a link between seeing this error and using your phone for development but I have no concrete evidence.
I find that if I plug my device in and its set to automatically run iPhoto - then you must let iPhoto load and let it try to sync photos before you quit it. Then you should be able to use XCode to load an application on to your phone.
If you do get the error - unplug the device, turn it off and then back on, and that usually clears up the problem
