objective c - Compare API value to a local stored value at each request to API -

ok, total brain freeze. have response ci jenkins api. result contains successful build number project @ jenkins increments each time successful build on jenkins platform runs.

now want app check request if there new successful build, , if there want inform user it. how can store current build number in app , compare each time make request check jenkins build number compare if local stored build number less build number on jenkins

[manager get:@"http://jenkins.myproject/lastsuccessfulbuild/api/json" parameters:nil success:^(afhttprequestoperation *operation, id responseobject) {     nsdictionary *responsedict = responseobject;      nsinteger repsonsbuildnumber = [responsedict[@"number"] integervalue];      if ([responsedict[@"result"] integervalue] == buildstatesuccess && repsonsbuildnumber > self.currentbuildnumber ) {         nslog(@"there new succesful build @ jenkins");     } else {         nslog(@"there currentbuildnumber same repsonsbuildnumber");     }  } failure:^(afhttprequestoperation *operation, nserror *error) {     nslog(@"error: %@", error); }]; 

so how can store currentbuildnumber compare repsonsbuildnumber whit each request?

nsuserdefaults perfect this. use -(nsinteger)integerforkey: current build number stored:

 nsinteger currentbuildnumber = [[nsuserdefaults standarduserdefaults] integerforkey:@"currentbuildnumber"]];  nsinteger repsonsbuildnumber = [responsedict[@"number"] integervalue];   if (currentbuildnumber < repsonsbuildnumber) {      // there new build  } 

then set it, use

[[nsuserdefaults standarduserdefaults] setinteger:repsonsbuildnumber forkey:@"currentbuildnumber"]];
