I have implemented react-native-timer-countdown package and it works fine just like given in the following example
https://github.com/avid21/react-native-timer-countdown
But I want the timer to stop on a function call rather when the mentioned time elapses.
Can this be done using this package? If not then please suggest me some other way by which I can do it.
Thanks In advance.

I'm working on an app, where I have lot of async calls to our server.
My problem is that many of these calls uses a token, and for everytime I call the server with a token, I will receive a new token. This means that my async calls get synchronized because they new the newest token.
I'm using Jonathan Willings code from here: https://gist.github.com/jwilling/7209108
This is ok, but it blocks my UI and I cannot figure out why.
Can anybody help me? Thanks in advance!
Sorry for the unclear question. I'm using the ASIFormDataRequest. I got it working by using a semaphore answered in this https://stackoverflow.com/questions/23021948/objective-c-possible-to-queue-async-nsurlrequests). It's important though to reset the semaphore everytime, so that the signal doesn't increment for every time no calls are waiting.
I'm currently trying to use the whenever gem to schedule my tasks but I do not know how it works. I've tried following the steps at https://github.com/javan/whenever but I got stuck at schedule.rb file. What am I supposed to write inside here? I want my app to call a method every minute using this gem. How am I supposed to do it? Can anyone give me a clue on how to do so?
UPDATE
I did the following to my application whereby it's supposed to send out an email every minute. I tried running the method without the scheduling and it works but it doesn't work if i schedule it, like the codes below. Is there something wrong with my code?
1) schedule.rb
every 1.minute do
runner "Newsletter.schedule_email"
end
2) newsletter.rb
def schedule_email
...*codes*...
end
Well, the basic form would be:
every 1.minute do
runner "Class.method_name"
end
If your stuff isn't running, this question might have some useful info:
Whenever cron job is not working in rails 3
There's also a railscast about cron jobs in general and Whenever in particular:
http://railscasts.com/episodes/164-cron-in-ruby
I envisage I'll run into problems as i haven't done this before.
I'm thinking that I can either define a date at the start of the method or initialise a class.
Then at the end of the method, call the commit method, which will write the time taken about with some sort of code to determine where the measurement was made.
Since you're crashing before the app finishes launching, so no code is going to fix this. If TestFlightApp isn't working, any other code-based solutions are likely to have the same problem.
As #dasblinkenlight noted, NSLog timestamps, so that's a really easy first step. Then you need to get the logs.
If possible, have your user install and run the iPhone Configuration Utility. Have her connect her device and select it from the Devices list. Then select Console and "Save Console As..." She can then mail it to you.
I would like my node.js tests to ensure that, once the test is over and test.finish() or similar is called, that there is no more code waiting to be run. No more I/O waiting to finish, no more timers waiting to fire, etc. etc.
Is this possible in node.js?
When using nodeunit each test function keeps running until test.done() has been called. Every test function needs to call this. This way you can make sure your callbacks have been executed. I also like to use async module to clean up my code(callbacks) a bit.
Are you using test.expect() at the beginning of each test and test.done() at the end of each one? Think of them like begin and end braces.
I wrote my own, which essentially spins up a node instance for each test. If your test leaves a callback dangling, node just won't exit, and the whole test suite hangs instead of exiting early with success (which would be bad!)
I wrote this code to hook API functions by changing the address in the IAT and EAT: http://pastebin.com/7d9N1J2c
This works just fine when I want to hook "recv" or "connect". However for some unknown reason when trying to hook "gethostbyname", my hook function is never called.
I tried to find "gethostbyname" in a debugger by taking the base address of the wsock32.dll module + 0x375e, which is what the ordinal 52 of my wsock32.dll is showing as offset. But that just makes me end up in some random asm code, not at the beginning of a function.
The same method however works fine for trying to find the "recv" entry point.
Does anyone see what I might be doing wrong?
I recommend this tool:
http://www.moduleanalyzer.com/
They do exactly the same and show the url that was connected with that API.
The problem is that there are more than one API to translate an url to an address. The application you are hooking may be using another version of the API that you're not intercepting.
Run some disassembler like IDA and attach to your process after you hook this functions, ida get apply changes on attaching and play process and check what is wrong.
In other way you have many libraries to do hooks with trampolines like Microsoft Detours, NCodeHook etc.
