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
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
