Request failed with http status code 503

I'm a newbie . Is there an example code base I can look at that shows how to 1 ) fire up JSON queries/reposes to/from multiple websites in parallel,2) have each taks/thread process info and write it to a central (shared) array of objects3) then wait for a parallel tasks to finish3) process the info collected on shared array data.I'm assuming this is about correct usage of asynchronous queues, and some tricks with a synchronous/wait for completion method. need to see the handling of hte dance. Also how to ensure the common global data object being written to safely from multiple parallel tasks.pointers to example code much appreciated

Hello All,I’ve created application which logs motion activity of user with CoreMotion framework and M7-chip functionality (I’m using CMMotionActivityManager).Application works fine in foreground. But I need to check that event occurred in 3-7 seconds frame in background mode.And I need to range iBeacons - check entering to specified zone in background mode and activate my test for the motion event.According following review http://developer.radiusnetworks.com/2013/11/13/ibeacon-monitoring-in-the-background-and-foreground.htmlthe time for detection is about 4 minutes (in average and up to 15 minutes) in background mode.Does exist any method or workaround to grab data for motion activity and ranging iBeacon in the background with better accuracy?- I need to check that event occurred in 3-7 seconds frame and notify user.My concept application works in the following way:1. I’ve activated background mode flags for CoreLocation and Audio (it plays audio signal on event detection).2. At start it requests

Hello,we had a problem saving the MagicStrings from the devices. Some devices are sending now their pushmagic again. But how could we enforce that on server or clientside?I am talking about that message: PUT: /checkin <?xml version=1.0 encoding=UTF-8?> <!DOCTYPE plist PUBLIC -/ http:/ <plist version=1.0> <dict> <key>MessageType</key> <string>TokenUpdate</string> <key>PushMagic</key> <string> [ redacted uuid string ] </string> <key>Token</key> <data> [ 32 byte string, base64 encoded, redacted ] </data> </data> <key>Topic</key> <string>com.example.mdm.pushcert</string> <key>UDID</key> <string> [ redacted ] </string> <key>UnlockToken</key> <data> [ long binary string encoded in base64, redacted ] </data> </dict> </plist> Thanks in advanceJuergen

Hello,In my app I use a NSURLConnection to upload some content. Everything works fine except when I reopen the app after like one hour.On my personal wifi, everything is fine, but when I connect using my operator data plan (I never observed any issue like this on other apps), the first NSURLConnection times out. If I try again, the operation succeeds.I use a standard NSURLConnection.NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:delegate];Using[NSURLConnection sendAsynchronousRequest:request...]also leads to a timeout.On another thread on the Apple developer forum somebody suggested to run a packet trace, which I did. The request does not seem to be sent.I'm a bit out of ideas, do you have one ?Thanks a lot!

Hello,I'm working on application, that works with user financial data.User should create account, log in, scan his personal card with social ID and get information from financial service.Requests to financial service are not free of charge.This service is provided by Local Authoritires and data could be retrieved after payment.I used IAP to buy Interrogations.For example - if user buys 10 interrogations - he can perform 10 requests to service.Every successful request decreases interrogation count by 1.Application was rejected with few reasons and i don't know exactly what they mean1) Abandoned BatchWe found that while you have submitted In App Purchase products for your app, the In App Purchase functionality is not present in your binary.But i can't add consumable abstract number of requests to binary - it's just stored at server side for every user.2) Missing restore mechanismYes, actually, app don't have special Restore button, but number of purchased interrogations is stored at s
