如何在iOS中快速显示多个标记的标记标题而不用点击它，就像iOS中照片库中的位置一样

Question

我无法显示标记的信息窗口，但是在加载地图时无需点击标记就可以显示信息吗？

Okay, since google maps currently don't provide this functionality by default here is a work around. When you create your marker manipulate it as follows:

• First you create a view and add your label and image to it.

   UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 100, 20)]; // Set label properties as required including marker Name UIImageView *markerIconImageView = [[UIImageView alloc]initWithFrame:CGRectMake(35, 10, 30, 50)]; // Set image properties as required including image which will be displayed as marker UIView *markerView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 100, 100)]; [markerView addSubview:label]; [markerView addSubview:markerIconImageView]; 

• Then you create a marker and assign it the image of above view:

   GMSMarker *marker = [[GMSMarker alloc] init]; marker.icon = [self imageWithView:markerView]; marker.position = coordinates for marker; marker.appearAnimation = kGMSMarkerAnimationPop; marker.map = your map; 

• For reference here is my function for converting view to image:

   -(UIImage *) imageWithView:(UIView *)view { UIGraphicsBeginImageContext(view.bounds.size); [view.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return image; } 

We have converted the view to image because. It takes up lesser space in memory.

Hope this helps. And gives you an idea for the approach.
