如何在Google地图上显示聚类标记的确切数量？

Question

我正在使用以下代码，用于marker clustering（使用存储桶生成群集图标）Google map sdk，

   id<GMUClusterIconGenerator> iconGenerator = [[GMUDefaultClusterIconGenerator alloc]initWithBuckets:@[@10,@50,@100,@500] backgroundImages:@[cluster1,cluster2,cluster3,cluster4]];

它正确地将标记聚类，但是在地图上显示10+或50+数字。例如，如果标记数量在地图35上显示10+，则标记数量超过50则在地图上显示50+等（请参阅下面的屏幕截图）。我想exact number of markers在群集上显示图片在地图上！！我的意思是，如果36要用的是标记数，则我要36代替10+。如果有谁可以帮忙！

我们可以通过更改一种GMUDefaultClusterIconGenerator类的方法来对其进行管理。

在GMUDefaultClusterIconGenerator.m替换以下方法中，

 - (UIImage *)iconForSize:(NSUInteger)size {
    NSUInteger bucketIndex = [self bucketIndexForSize:size];
    NSString *text;

    // If size is smaller to first bucket size, use the size as is otherwise round it down to the
    // nearest bucket to limit the number of cluster icons we need to generate.
    if (size < _buckets[0].unsignedLongValue) {
    text = [NSString stringWithFormat:@"%ld", (unsigned long)size];
    } else {
    text = [NSString stringWithFormat:@"%ld+", _buckets[bucketIndex].unsignedLongValue];
  }
   if (_backgroundImages != nil) {
    UIImage *image = _backgroundImages[bucketIndex];
    return [self iconForText:text withBaseImage:image];
}
     return [self iconForText:text withBucketIndex:bucketIndex];
 }

与

 - (UIImage *)iconForSize:(NSUInteger)size {
    NSUInteger bucketIndex = [self bucketIndexForSize:size];
    NSString *text;

    // If size is smaller to first bucket size, use the size as is otherwise round it down to the
   // nearest bucket to limit the number of cluster icons we need to generate.
   if (size < _buckets[0].unsignedLongValue) {
     text = [NSString stringWithFormat:@"%ld", (unsigned long)size];
   }


  else{
    text = [NSString stringWithFormat:@"%ld", (unsigned long)size];
  }

  if (_backgroundImages != nil) {
    UIImage *image = _backgroundImages[bucketIndex];
    return [self iconForText:text withBaseImage:image];
  }
  return [self iconForText:text withBucketIndex:bucketIndex];
 }

我所做的是，我只更改了else部分并设置text为exact number而不是string with +！
