100grams / moving-mkannotationview Goto Github PK

Seems like you did a ton of work trying to solve this problem however you'll find this simple trick of setting the annotation again will cause it to update to the new coordinate:

MKAnnotationView* annotationView = [self.mapView viewForAnnotation:a];
a.coordinate = newCoordinate;
annotationView.annotation = a;

Furthermore if you want to animate the move just do:

[UIView animateWithDuration:0.5 animations:^{
a.coordinate = coordinate;
annotationView.annotation = a;
}];

FYI I saw you setting a mapView on your HGMovingAnnotationView causing a circular reference, tut tut you should be ashamed ;-)

I want to add cars on the map and show their movement but the problem is that I am getting the position of cars from an api.So I want to animate cars through the latitude and longitude that I am getting from that api.How can I achieve that?Any help will be much appreciated.

Hi,

Thanks a lot for the Post Moving MKAnnotationView. Its very helpful and its been used by many. I came across a similar kind of requirement where i need to animate the annotation points between multiple map points. I was able to do it with the post u have suggested but apart from that i need to stop the animation at certain annotation points and wait for 2 seconds and then start the animation again. Can you please help me? It would be of great help if any alternative or suggestion is provided for this..

@100grams In ios 7 annotation is blinking when move and not shows soft animation like ios 6.

When the map region changes, the "moving" pin is dragged with the slide and then returns to its place to continue moving... any ideas how to fix the pin when the user changes the region of the map? Thanks!

Hi Rotem,

From your yesterday's answer i have got an understanding on how this should be done. But my problem here lies in when the annotation point where it should stop at a particular point and then resume from that stopped point. HGMovingAnnotation Class has a "Stop" Method but when i tried to call the Stop method from "startTracking" Method it doesn't get called. I am actually checking the condition if the currentLocation reaches certain location coordinates.

double latitude = currentLocation.x;
double longitude = currentLocation.y;
if (latitude == 137472336.403570 && longitude == 90052702.711254 ) {
NSLog(@"Inside If condition");
[self stop];
}

Can you please suggest me an alternative on how to implement this?
