so question : how connect webserver exchange json objects ? searched on couldnt find .

there simple ways connect server ios app. can using nsurlrequest or nsurlconnection. simple understand , implement.

apple docs on connecting using http , https.

nsurlrequest documentation.

nsurlconnection tutorial (contains multiple methods in class).

using these can establish connection server , make requests.

now, since did mention json, there class called jsonhttpclient. have used success several times fetch , parse json. here useful tutorial can started.

another option work using datawithcontentsofurl:options:error: nsdata class. somthing like:

nsdata * data = [nsdata datawithcontentsofurl: [nsurl urlwithstring:@"yoururlhere.com"]]; 

if url returns json, can download , parse using
