hi guys, I'm trying to implement a retry on http request timeout on my IOS apps, i've set the timeout interval as the code below



the problem is, i tested the interval by connecting my iPhone to a 3g hotspot, then turning off the 3g and initiate the curl request and here's the result that i logged



as you can see from the log time, the interval between retries is 4-5 secs apart and not 10 secs.. although this is acceptable for me, i'd like to know, why and where is the 4-5 sec limit set, i've googled around and couldn't find an answer to this. is it default to the NSURLRequest class? do apple enforce 4-5 sec retries on no internet? why is it like that? help guys, any answer is appreciated.

Hi,

If it were for me, I won't use the native URL request in Objective C

Try looking for AFNetworking.

Almost ALL iOS apps runs on it. It handles your timeout session in a block, and it is asynchronous, hence, you can control the timeout block as you like.

Furthermore, if you were to check for slow / no internet, you should not use timeout as a threshold to determine whether 3g/4g/Wifi is available. It is not recommended.

Edit :

You can refer to this.

It maybe due to your POST request, and it was only fixed iOS 6 and above.

Try setting the timeout period higher, maybe to 60~120 seconds, see will it run correctly or not.
