ios - GMSMapView 自定义我的位置按钮图片

Question

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。

Answer 1

1) 知道框架位置按钮:

   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) 为这个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];
