您在屏幕上有注释。注释是纬度和纬度值。
NSArray *data = [root objectForKey:@"data"];
for (NSArray *row in data) {
NSNumber * latitude = [[row objectAtIndex:22]objectAtIndex:1];
NSNumber * longitude = [[row objectAtIndex:22]objectAtIndex:2];
NSString * crimeDescription = [row objectAtIndex:18];
NSString * address = [row objectAtIndex:14];
CLLocationCoordinate2D coordinate;
coordinate.latitude = latitude.doubleValue;
coordinate.longitude = longitude.doubleValue;
MyLocation *annotation = [[MyLocation alloc] initWithName:crimeDescription address:address coordinate:coordinate] ;
[_mapView addAnnotation:annotation];
}
