从视图中删除MKAnnotationView默认标注 [英] Remove MKAnnotationView Default Callout From View

问题描述

我正在尝试 MKMapKit ，以防止在点击 MKMapView上显示的标记时显示默认注释标注 无 阻止委托调用/注释的交互(见下文).

I am trying to prevent MKMapKit from presenting the default annotation callout when tapping on a marker displayed on a MKMapView without blocking the delegate call / interaction of the annotation (seen below).

- (void)mapView:(MKMapView *)mapView didSelectAnnotation:(MKAnnotationView *)view {

    // Custom callout initialized & presented here
    . . .

}

我了解您可能会禁止标注完全显示

I understand you may disable the callout from showing entirely

someAnnotationView.canShowCallout = NO;

或(更多的是骇人听闻的方法)不设置注释的任何显示参数:

or (more of a hackish approach) not setting any display parameters of the annotation:

// Commenting out string assignments below

// someAnnotation.title = @"Hey!";
// someAnnotation.subTitle = @"Aren't I an annoying callout :P ?";

正如在其他主题中所建议的，将子视图添加到注解视图确实的确确实将自定义视图(随心所欲)添加到您选择的边界框架中.

As suggested in other threads, adding a subview to the annotation view does indeed add a custom view (whatever you please) to a bounding frame of your choice.

问题是添加子视图

1. 不阻止默认标注气泡的出现
2. 如果，您禁用了 canShowCallout 或，请不要设置标签，否则注释交互会丢失..
3. 如果，您添加了一个子视图，它会被添加到下方默认的标注中.

1. Does not stop the default callout bubble from appearing
2. IF you disable canShowCallout OR don't set the labels, annotation interaction is lost..
3. IF you add a subview, it gets added below the default callout.

3注意您可以将添加子视图的时间延迟+0.5秒，这将在上方添加自定义视图，但是这是一个很差的解决方法，因为您会看到默认的标注早于您的视图.

3 NOTE You can delay the addition of your subview by +0.5 seconds, which then will add your custom view above the callout, but this is a poor workaround as you see the default callout come into view well before yours..

是否有任何解决方法

1. 删除默认标注，而不会禁止调用委托方法，
2. 或编辑实际的标注视图(我猜它是某些 CGPath 或 UIBezierePath 绘制的视图)

1. Removing the default callout without disabling the delegate method from being called,
2. or Editing the actual callout view (I'm guessing it's some CGPath or UIBezierePath drawn view)

任何帮助将不胜感激.谢谢！

Any help would be appreciated. Thanks!

更新:

我正在使用委托 mapView:viewForAnnotation 创建和向我的地图添加注释视图.

I am using the delegate mapView:viewForAnnotation to create and add annotation views to my map.

推荐答案

选中后，同时删除注释的标题和副标题:

When selected remove both title and subtitle of the annotation:

    func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
        if let annotation = view.annotation {
            annotation.title = nil
            annotation.subtitle = nil
        }
    }
