Get CoreLocation Update before TableView population?
- by Clemens
hi,
i have the corelocation stuff in an uitableview controller. i actually want to get a distance from two locations and print that distance in a tableview cell.
the problem is, that the tableview is filled before all the corelocation stuff happens. how can i make corelocation makes all updates before the table is filled?
heres my class:
