create CLLocationCoordinate2D from array
- by shani
I have a plist with dictionary of array's with coordinates (stored as strings).
I want to create a CLLocationCoordinate2D from every array and crate an overlay for the map.
I did that -
NSString *thePath = [[NSBundle mainBundle] pathForResource:@"Roots" ofType:@"plist"];
NSDictionary *pointsDic = [[NSDictionary alloc] initWithContentsOfFile:thePath];
NSArray *pointsArray = [NSArray arrayWithArray:[pointsDic objectForKey:@"roade1"]];
CLLocationCoordinate2D pointsToUse[256];
for(int i = 0; i < 256; i++) {
CGPoint p = CGPointFromString([pointsArray objectAtIndex:i]);
pointsToUse[i] = CLLocationCoordinate2DMake(p.x,p.y);
NSLog(@"coord %f",pointsToUse [i].longitude);
NSLog(@"coord %f",pointsToUse [i].latitude);
}
MKPolyline *myPolyline = [MKPolyline polylineWithCoordinates:pointsToUse count:256];
[[self mv] addOverlay:myPolyline];
but the app is crashing without any error.
(BTW when i remove the addOverLay method the app does not crash).
I have 2 questions-
What am i doing wrong?
I have tried to set the pointsArray count as the argument for the CLLocationCoordinate2D like that -
CLLocationCoordinate2D pointsToUse[pointsArray count];
And i am getting an error.
How can i set the CLLocationCoordinate2D dynamically ?
Thanks for any help.
