Question

I am creating a map application in Objective-C, for iPhone. I know how to get the current location of the user, and the destination location. As a user travels, his coordinates (latitude and longitude) change.

How can I save the latitude and longitude of the user in an SQLite database every five minutes as the user travels?

Answer 1

You can use a timer and set time interval to 300, as shown below

[NSTimer scheduledTimerWithTimeInterval:300 target:self selector:@selector(*savetodatabase*) userInfo:nil repeats:YES];

Make one function which is called every 5 mins and save it to database.

NOTE: Here 300 is in seconds
