Requirement: Get the data from the cache if NSMutableURLRequest can not fetch data from the server.If internet available and i got the data from the server then function will return server data but if request fail to get the data from the server then function will return the NSCache data according to cachePolicy.
To resolve this issue i changed the cachePolicy from NSURLRequestReloadIgnoringLocalCacheData to NSURLRequestReturnCacheDataElseLoad. Now I am getting the data from NSCache.
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
configuration.timeoutIntervalForRequest=TimeOfRequestOut;
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration];
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestReturnCacheDataElseLoad //HERE IS THE CHANGE
timeoutInterval:TimeOfRequestOut];
Now, I need to find out when this function returning NSCache data and when it's returning data from live server and It will also helpful, if someone tell me is it right approach to get cache data?
