我想知道是否可以将我的位置按钮图像从 GMSMapView 更改为自定义图像。

1）知道帧位置按钮：

   for (UIView *object in self.mapView.subviews) {
    if([[[object class] description] isEqualToString:@"GMSUISettingsView"] )
    {
        for(UIView *view in object.subviews) {
            if([view.accessibilityIdentifier isEqual:@"my_location"] ) {

                frame = view.frame;

            }
        }

    }
   }

使用调试查看正确的帧！！！

2) 不要使用 self.mapView.settings.myLocationButton = YES;

3）为此框架创建自己的按钮：

    UIButton *buttonLocation = [UIButton buttonWithType:UIButtonTypeRoundedRect];
buttonLocation.frame = CGRectMake([UIScreen mainScreen].bounds.size.width - 66, [UIScreen mainScreen].bounds.size.height - frame.size.height, frame.size.width, frame.size.height);
[buttonLocation addTarget:self
           action:@selector(bLocations:)
 forControlEvents:UIControlEventTouchUpInside];
[buttonLocation setImage:[[UIImage imageNamed:@"image.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] forState:UIControlStateNormal];

[self.mapView addSubview:buttonLocation];

继之前的答案（使用从 GMSMapView 获取 UIButton 引用的方法）之后，这里是 Swift 中的更新答案。它将默认的“我的位置”图标替换为您自己的自定义图像。

private func setupMyLocationButton() {
  let locationButton = mapView.subviews
    .filter { $0.description.contains("GMSUISettingsPaddingView") }
    .flatMap { $0.subviews }
    .flatMap { $0.subviews }
    .filter { $0.description.contains("GMSx_QTMButton") }
    .first
  let customImage = UIImage(imageLiteralResourceName: "yourCustomIconFilename")
  let myLocationButton = locationButton as? UIButton
  myLocationButton?.setImage(customImage, for: .normal)
}

为此，您可以从 GMSMapView 中检索对该按钮的 UIButton 引用。之后，您只需将标准 [UIButton setImage:] 用于所有不同的状态。我创建了一个从 GMSMapView 控件中获取此 UIButton 的类别：
