我正在使用Google IOS SDK并已实施
- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker
实现自定义视图。当我显示此视图时,它不会添加标注,因为Google地图视图通常会为其自己的标记添加。任何人都可以让我知道如何添加这个标注像指针指向这个自定义makerInfoWindow的标记?

以下是如何做到的。
- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker{
int popupWidth = 300;
int contentWidth = 280;
int contentHeight = 140;
int contentPad = 10;
int popupHeight = 200;
int popupBottomPadding = 16;
int popupContentHeight = contentHeight - popupBottomPadding;
int buttonHeight = 30;
int anchorSize = 20;
CLLocationCoordinate2D anchor = marker.position;
CGPoint point = [mapView.projection pointForCoordinate:anchor];
UIView *outerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, popupHeight)];
float offSet = anchorSize * M_SQRT2;
CGAffineTransform rotateBy45Degrees = CGAffineTransformMakeRotation(M_PI_4); //rotate by 45 degrees
UIView *callOut = [[UIView alloc] initWithFrame:CGRectMake((popupWidth - offSet)/2.0, popupHeight - offSet, anchorSize, anchorSize)];
callOut.transform = rotateBy45Degrees;
callOut.backgroundColor = [UIColor blackColor];
[outerView addSubview:callOut];
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, 190)];
[view setBackgroundColor:[UIColor whiteColor]];
view.layer.cornerRadius = 5;
view.layer.masksToBounds = YES;
view.layer.borderColor = [UIColor blackColor].CGColor;
view.layer.borderWidth = 2.0f;
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(contentPad, 0, contentWidth, 22)];
[titleLabel setFont:[UIFont systemFontOfSize:17.0]];
titleLabel.text = [marker title];
UILabel *descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(contentPad, 24, contentWidth, 80)];
[descriptionLabel setFont:[UIFont systemFontOfSize:12.0]];
descriptionLabel.numberOfLines = 5;
descriptionLabel.text = [marker snippet];
[view addSubview:titleLabel];
[view addSubview:descriptionLabel];
[outerView addSubview:view];
return outerView;
}

此方法是GMSMapViewDelegate
方法,您是否将委托设置为视图控制器?
mapView.delegate = self;
