ios - AnnotationView 在 calloutVIew 上重叠
<p><p>我正在使用 MapKit 在 map 上显示数据。为此，我使用自定义 AnnotationView 和自定义 CalloutView。但问题是，当我让 AnnotationView 相互关闭时，AnnotationView 在 CalloutView 上重叠。这是问题的截图。<br/><br/>

<p>按钮也有问题，按钮的点击事件没有被调用。 calloutView 下方的 4 个按钮不会在点击时被调用。但是右上角代表编辑事件的按钮在点击时会被触发。</p>
<p>这是我的 CalloutView 代码。</p>
<pre><code>@implementation CustomCalloutView
- (id)init {
return self;
}
- (IBAction)btnEditAction:(UIButton *)sender {
;
}
- (IBAction)btnMailAction:(UIButton *)sender {
;
}
- (IBAction)btnMessageAction:(UIButton *)sender {
;
}
- (IBAction)btnCallAction:(UIButton *)sender {
;
}
- (IBAction)btnStreetAction:(UIButton *)sender {
;
}
- (IBAction)CalloutTapGestureClicked:(UITapGestureRecognizer*)sender {
;
}
@end
</code></pre>
<p>请帮我解决这个问题...</p></p>

<p><p>这样做可以防止重叠(在顶部插入 callOutView )</p>
<pre><code> func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView)
{
print("clickedddddddd")
if view.annotation is MKUserLocation
{
return
}
let customView = (Bundle.main.loadNibNamed("customSou", owner: self, options: nil))? as! customSouOut;
var calloutViewFrame = customView.frame;
calloutViewFrame.origin = CGPoint(x:-calloutViewFrame.size.width/2 + 15,y: -calloutViewFrame.size.height);
customView.frame = calloutViewFrame;
view.addSubview(customView)
// here you can fill any label or button with data according to it's pin
//
for v in view.subviews
{
if v is customSouOut
{
continue
}
else
{
view.insertSubview(customView, aboveSubview: v)
}
}
}
}
func mapView(_ mapView: MKMapView, didDeselect view: MKAnnotationView)
{
print("oppspspspsps")
if view.annotation is MKUserLocation
{
return
}
for v in view.subviews
{
if v is customSouOut
{
v.removeFromSuperview()
break
}
}
}
</code></pre></p>
