闪烁自定义标记在Google地图iOS中

Question

我在谷歌地图iOS SDK中放置了6个具有相同坐标的自定义标记.这些标记持续闪烁/切换.我根本不想要动画闪烁.请帮我.

这是我的源代码.

-(void)loadPlacesInMapWithIndex:(int)index{

    for (int i = 0; i < [[[SearchManager sharedInstance]searchedStallArray] count]; i++) {
        Stall *stall = [[[SearchManager sharedInstance]searchedStallArray] objectAtIndex:i];

        // Creates a marker in the center of the map.
        GMSMarker *marker = [[GMSMarker alloc] init];
        marker.position = CLLocationCoordinate2DMake([stall.stallLatitude doubleValue],[stall.stallLongitude doubleValue]);
        marker.infoWindowAnchor = CGPointMake(0.44f, -0.07f);
        marker.userData = stall;
        marker.tappable = YES;
        self.infoView = [[[NSBundle mainBundle]loadNibNamed:@"StallInfoWindow" owner:self options:nil] objectAtIndex:0];

        marker.iconView = self.infoView;
        if (index == i) {
            [self.infoView.stallPinImageView setImage:[UIImage imageNamed:@"RateLabel.png"]];
            [self.infoView.stallPriceLabel setTextColor:[UIColor whiteColor]];

            CGFloat currentZoom = self.stallsMapView.camera.zoom;
            [CATransaction begin];
            [CATransaction setValue:[NSNumber numberWithFloat: 0.5f] forKey:kCATransactionAnimationDuration];
            [self.stallsMapView animateToCameraPosition:[GMSCameraPosition
                                                          cameraWithLatitude:[stall.stallLatitude doubleValue]
                                                          longitude:[stall.stallLongitude doubleValue]
                                                          zoom:currentZoom]];
            [CATransaction setCompletionBlock:^{
            }];
            [CATransaction commit];

        }else{
            [self.infoView.stallPinImageView setImage:[UIImage imageNamed:@"horse.png"]];
            [self.infoView.stallPriceLabel setTextColor:[UIColor redColor]];
        }

        self.infoView.stallPriceLabel.text = [NSString stringWithFormat:@"$%@",stall.stallPrice];

        marker.map = self.stallsMapView;
    }
}

Answer 1

你必须提供不同的zIndex属性.此属性定义哪个标记位于堆栈顶部.最高的数字是最重要的.

对于您的代码,请插入:

 marker.tappable = YES;

这行代码:

 marker.zIndex = (UInt32)i

Answer 2

您是否尝试过设置标记的 zIndex 属性？标记可能会闪烁，因为它们重叠并且没有明确的绘制顺序。
