ios – 如何在GMSMapView上设置自定义注释标记(围绕点的动画环)

使用谷歌地图iOS SDK我已经实现了mapView
因为我已经创建了如下标记

// Creates a marker in the center of the map.
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake(-33.86,151.20);
marker.title = @"Sydney";
marker.snippet = @"Australia";

marker.icon = [UIImage imageNamed:@"point1.png"]; 

marker.map = mapView_;

但我需要显示动画图像,即要显示的一些图像序列,一个点周围的动画环,而不是原始的GMSMarker

图像序列为point1.png point2.png point3.png point4.png point5.png

任何人都可以帮助我实现这一目标

解决方法

在

- (RMMapLayer *)mapView:(RMMapView *)mpView layerForAnnotation:(RMAnnotation *)annotation
{

  UIImageView *pulseRingImg = [[UIImageView alloc] initWithFrame: CGRectMake(-30,-30,78,78)];
    pulseRingImg.image = [UIImage imageNamed:@"pulseRing.png"];
     pulseRingImg.userInteractionEnabled = NO;

    CABasicAnimation *theAnimation;
    theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.scale.xy"];
    theAnimation.duration=2.0;
    theAnimation.repeatCount=HUGE_VALF;
    theAnimation.autoreverses=NO;
    pulseRingImg.alpha=0;
    theAnimation.fromValue=[NSNumber numberWithFloat:0.0];
    theAnimation.tovalue=[NSNumber numberWithFloat:1.0];
    pulseRingImg.alpha = 1;
    [pulseRingImg.layer addAnimation:theAnimation forKey:@"pulse"]; 
     pulseRingImg.userInteractionEnabled = NO;

    [mapView addSubview:pulseRingImg];
    [marker addSublayer:pulseRingImg.layer];

 return marker;

}

[UIImage imageNamed：@“pulseRing.png”]中的pulseRing.png是

CABasicAnimation *theAnimation;

theAnimation=[CABasicAnimation animationWithKeyPath:@"opacity"];
theAnimation.duration=1.0;
theAnimation.repeatCount=HUGE_VALF;
theAnimation.autoreverses=YES;
theAnimation.fromValue=[NSNumber numberWithFloat:1.0];
theAnimation.tovalue=[NSNumber numberWithFloat:0.0];
[myButton.layer addAnimation:theAnimation forKey:@"animateOpacity"];
