在Google地图上为ios添加自定义标记上的文字 [英] Add text on custom marker on google map for ios

问题描述

我试图用Textview标记标记。是否有任何可能性在iOS中的谷歌地图上添加标记。

解决方案

您必须创建一个视图，您必须创建一个imageView（带有标记图像）和Label与您的文本），并截取该视图的截图，并设置为您的GMSMarker图标。
类似于这样：

$ $ $
$

$ G $标记= [GMSMarker新];

UIView * view = [[UIView alloc] initWithFrame：CGRectMake（0,0,60,60）];
UIImageView * pinImageView = [[UIImageView alloc] initWithImage：[UIImage imageNamed：@myPin]];
UILabel * label = [UILabel new];
label.text = @1;
//label.font = ...;
[label sizeToFit];

[view addSubview：pinImageView];
[view addSubview：label];
//i.e。定制视图以获取所需内容


UIImage * markerIcon = [self imageFromView：view];
marker.icon = markerIcon;
marker.map = self.mapView; $ {
}
$ b - （UIImage *）imageFromView：（UIView *）view
{
if（[[UIScreen mainScreen] respondsToSelector：@selector（scale）]）） {
UIGraphicsBeginImageContextWithOptions（view.frame.size，NO，[[UIScreen mainScreen] scale]）;
} else {
UIGraphicsBeginImageContext（view.frame.size）;
}
[view.layer renderInContext：UIGraphicsGetCurrentContext（）];
UIImage * image = UIGraphicsGetImageFromCurrentImageContext（）;
UIGraphicsEndImageContext（）;
返回图片;
}

Am trying to put marker with Textview .Is there any posibility to add text over marker on google map in ios.

解决方案

You must make a view, where you must create an imageView (with your marker image) and Label (with your text) and take a screenshot of that view, and set as icon to your GMSMarker. Something like this:

- (void)foo
{
    GMSMarker *marker = [GMSMarker new];

    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0,0,60,60)];
    UIImageView *pinImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"myPin"]];
    UILabel *label = [UILabel new];
    label.text = @"1";
    //label.font = ...;
    [label sizeToFit];

    [view addSubview:pinImageView];
    [view addSubview:label];
    //i.e. customize view to get what you need    


    UIImage *markerIcon = [self imageFromView:view];
    marker.icon = markerIcon;        
    marker.map = self.mapView;      
}

- (UIImage *)imageFromView:(UIView *) view
{
    if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)]) {
        UIGraphicsBeginImageContextWithOptions(view.frame.size, NO, [[UIScreen mainScreen] scale]);
    } else {
        UIGraphicsBeginImageContext(view.frame.size);
    }
    [view.layer renderInContext: UIGraphicsGetCurrentContext()];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}
