I am working with Maps and i have 2 thousand latitudes and longitudes of germany specific locations in CSV file. It take 3-4 mins to drop all the pins on map when clicked.

I want to that map should open quickly on gps values and show pins for that specific region. if user moves on map then it drops pins but not wait in this all process like we have now about 3-4 mins.

  • @Neznajka actually i know how to drop a pin. but i was user able to see his location (i have done with it). now i want him to show his location (Region) pins only to drop on map. – Amir iDev Feb 07 '13 at 04:32

  • @JayD I have CSV File for specific locations, I have to use this file to drop pins. I have also tried "KMLViewer", I want to drop pins for current location first or only for Current Region which is shown in map right now. – Amir iDev Feb 07 '13 at 20:21

I made a Selector and perform it on background and use it on -viewDidLoad method. The use will see the map without any wait 

[self performSelectorInBackground:@selector(readFileAndDropPin) withObject:self];
