Why am I unable to remove my annotations from mapview?
My code:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self becomeFirstResponder];
NSMutableArray *annotations = [[NSMutableArray alloc]init];
NSString *path = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"plist"];
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:path];
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"blackKey"])
{
NSLog(@"Black is on");
NSArray *ann = [dict objectForKey:@"Category1"];
for(int i = 0; i < [ann count]; i++) {
NSString *coordinates = [[ann objectAtIndex:i] objectForKey:@"Coordinates"];
double realLatitude = [[[coordinates componentsSeparatedByString:@","] objectAtIndex:1] doubleValue];
double realLongitude = [[[coordinates componentsSeparatedByString:@","] objectAtIndex:0] doubleValue];
MyAnnotation *myAnnotation = [[MyAnnotation alloc] init];
CLLocationCoordinate2D theCoordinate;
theCoordinate.latitude = realLatitude;
theCoordinate.longitude = realLongitude;
myAnnotation.coordinate=CLLocationCoordinate2DMake(realLatitude,realLongitude);
myAnnotation.title = [[ann objectAtIndex:i] objectForKey:@"Name"];
myAnnotation.subtitle = [[ann objectAtIndex:i] objectForKey:@"Address"];
myAnnotation.icon = [[ann objectAtIndex:0] objectForKey:@"Icon"];
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"blackKey"])
{
NSLog(@"Black is on");
[mapView addAnnotation:myAnnotation];
[annotations addObject:myAnnotation];
} else
{
NSLog(@"Black is off");
[self.mapView removeAnnotation:myAnnotation];
}
}
}
else
{
//Do nothing
}
}
[self.mapView removeAnnotation:myAnnotation]; does not work for me
