我在mapkit中显示了当前位置注释(蓝点)。在录制蓝点后显示注释, 当我启动视图时,如何在默认情况下显示注释?发出针脚。
- (void)mapView:(MKMapView *)mv didAddAnnotationViews:(NSArray *)views {
for(MKAnnotationView *annotationView in views) {
if(annotationView.annotation == mv.userLocation) {
self.mapView.userLocation.title= @"Current";
self.mapView.userLocation.subtitle= @"Location";
MKCoordinateRegion region;
MKCoordinateSpan span;
span.latitudeDelta=0.002;
span.longitudeDelta=0.002;
CLLocationCoordinate2D location=mv.userLocation.coordinate;
region.span=span;
region.center=location;
[mv setRegion:region animated:YES];
[mv regionThatFits:region];
}
}
}

在这种情况下,selectAnnotation应该可以工作,不是吗?只需在一小段时间后执行Selector。
....与以前相同的代码,但插入此内容:
id annotation = annotationView.annotation;
[self performSelector:@selector(selectUserLocation:) withObject:annotation afterDelay:0.1f];
}
}
}
- (void)selectUserLocation:(id)annotation{
[self.mapView selectAnnotation:annotation animated:YES];
}
