Hello,

Im working on an iPhone project using xcode and i actually have not programmed using objective-c before. So, my problem mainly is that my app crashes whenever i hit the button that it suppose to show a view of the world map. I think the problem is within the last 2 lines of the code but still i cant figure out why ?!! because whenever i comment out the line "[self presemtM.....]" the program doesn't crash. Would appreciate your help!

-(IBAction) pushedGo:(id)sender { CLLocationCoordinate2D coord = {37.331689, -122.030731};

MapViewController *mapView = [[MapViewController alloc] initWithCoordinates:coord andTitle:@"Apple" andSubTitle:@"111"];

[self presentModalViewController:mapView animated:YES]

[mapView release];

}
