我想使用GMUClusterManager显示自定义标记.我按照标记聚类
here的所有步骤进行操作.
有实例方法,我已经实现了我的逻辑,但没有用.
- (instancetype)initWithMapView:(GMSMapView *)mapView clusterIconGenerator:(id<GMUClusterIconGenerator>)iconGenerator
{
if ((self = [super init])) {
GMSMarker *marker= [GMSMarker markerWithPosition:CLLocationCoordinate2DMake(24.0,75.30)];
UIView *customMarker =[[UIView alloc] initWithFrame:CGRectMake(0,63,40)];
customMarker.backgroundColor = [UIColor blueColor];
marker.iconView = [self EmployeeMarker:0] ;
marker.appearAnimation = kGMSMarkerAnimationPop;
marker.map = mapView;
}
return self;
}
-(UIView *)EmployeeMarker:(int)labelTextInt{
UIView *customMarker =[[UIView alloc] initWithFrame:CGRectMake(0,40)];
UIImageView *imgViewCustomMarker = [[UIImageView alloc]initWithFrame:CGRectMake(0,15,24,25)];
imgViewCustomMarker.image = [UIImage imageNamed:@"iconMapUser.png"];
[customMarker addSubview:imgViewCustomMarker];
UIView *viewRatingCustom = [[UIView alloc] initWithFrame:CGRectMake(15,40,15)];
viewRatingCustom.backgroundColor = [UIColor colorWithRed:192.0/255.0 green:192.0/255.0 blue:192.0/255.0 alpha:1.0];
UILabel *lblRatingEmployees = [[UILabel alloc] initWithFrame:CGRectMake(8,1,17,8)];
lblRatingEmployees.textColor = [UIColor colorWithRed:0.00/255.0 green:100.0/255.0 blue:150.0/255.0 alpha:1.0];
lblRatingEmployees.text = @"1";
lblRatingEmployees.font = [UIFont fontWithName:@"Helvetica-Bold" size:10];
[lblRatingEmployees sizeToFit];
[viewRatingCustom addSubview:lblRatingEmployees];
UIImageView *imageViewStar = [[UIImageView alloc] initWithFrame:CGRectMake(25,3,10,8)];
imageViewStar.image = [UIImage imageNamed:@"iconBlueStar.png"];
[viewRatingCustom addSubview:imageViewStar];
[customMarker addSubview:viewRatingCustom];
return customMarker;
}
id<GMUClusterAlgorithm> algorithm = [[GMUNonHierarchicalDistanceBasedAlgorithm alloc] init];
id<GMUClusterIconGenerator> iconGenerator = [[GMUDefaultClusterIconGenerator alloc] init];
id<GMUClusterRenderer> renderer =
[[GMUDefaultClusterRenderer alloc] initWithMapView:_mapView
clusterIconGenerator:iconGenerator];
_clusterManager =
[[GMUClusterManager alloc] initWithMap:_mapView algorithm:algorithm renderer:renderer];
// Generate and add random items to the cluster manager.
// [self generateClusterItems];
for (int i = 0; i<latitudeArray.count; i++) {
id<GMUClusterItem> item =
[[POIItem alloc]initWithPosition:CLLocationCoordinate2DMake([[latitudeArray objectAtIndex:i]doubleValue],[[longitudeArray objectAtIndex:i]doubleValue]) name:@"Name"];
[_clusterManager addItem:item];
}
Adde代表和集群方法.
[_clusterManager cluster]; [_clusterManager setDelegate:self mapDelegate:self];
解决方法
您需要创建符合GMUClusterIconGenerator协议的自定义类：
CustomClusterIconGenerator.h文件
@interface CustomClusterIconGenerator : NSObject <GMUClusterIconGenerator> @end
CustomClusterIconGenerator.m文件
@implementation CustomClusterIconGenerator
- (UIImage *)iconForSize:(NSUInteger)size {
// Return custom icon for cluster
return [UIImage imageNamed:@"Your Custom Cluster Image"];
}
- (UIImage *)iconForMarker {
// Return custom icon for pin
return [UIImage imageNamed:@"Your Custom Marker Image"];
}
- (CGPoint)markerIconGroundAnchor {
// If your marker icon center shifted,return custom value for anchor
return CGPointMake(0,0);
}
- (CGPoint)clusterIconGroundAnchor {
// If your cluster icon center shifted,0);
}
@end
然后,而不是
id<GMUClusterIconGenerator> iconGenerator = [[GMUDefaultClusterIconGenerator alloc] init];
使用
CustomClusterIconGenerator *iconGenerator = [[GMUDefaultClusterIconGenerator alloc] init];
