如何在Google地圖上顯示聚集標記的確切數量？

Question

我使用以下代碼marker clustering（用於產生與水桶集羣圖標）使用Google map sdk，

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

它被適當地標記聚類但它是表示在地圖上的10+或50+號碼。例如，如果標記物的數量35則當標記物的數量超過50則顯示50+等顯示在地圖上，10+（參照以下附圖）。我想在地圖上顯示集羣上的exact number of markers！我的意思是，如果標記的數量36然後我想36，而不是10+。如果有人可以幫助！

我們可以通過改變GMUDefaultClusterIconGenerator類的一種方法管理。

在GMUDefaultClusterIconGenerator.m取代下面的方法，

- (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]; 
} 

與

- (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]; 
} 

我做了什麼時，我只是改變其他部分，並設置text爲exact number而不是string with +！
