【中文标题】带有图像的 MKPinAnnotationView 内的 UIButton【英文标题】:UIButton inside MKPinAnnotationView with image 【发布时间】:2015-11-06 20:00:21 【问题描述】:我需要在左侧使用 MKPinAnnotationView
和 UIButton
使用如下图像:
我尝试编写此代码,但它不起作用:
let navBtn = UIButton(type: .Custom)
navBtn.setImage(UIImage(named: "TakeMe.png"), forState: .Selected)
navBtn.tag = artwork.id
navBtn.addTarget(self, action: "wazeNav:" , forControlEvents: UIControlEvents.TouchUpInside)
pinView?.rightCalloutAccessoryView = btn
pinView?.leftCalloutAccessoryView = navBtn
请帮助我如何做到这一点?
【问题讨论】:
你有什么错误吗? 不只是看不到按钮 你是在 viewForAnnoation 中调用这个吗? 我不这么认为,我该怎么做? 【参考方案1】:请参考下面的代码
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView!
let annotationView = AttractionAnnotationView(annotation: annotation, reuseIdentifier: "Attraction")
let button : UIButton = UIButton(type: UIButtonType.InfoDark)
button.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
button.addTarget(self, action: "funcRightAcessoryButton:", forControlEvents: UIControlEvents.TouchUpInside)
annotationView.rightCalloutAccessoryView = button
annotationView.canShowCallout = true
let image = UIImage(named: "left_icon")
let buttonLeft : UIButton = UIButton(type: UIButtonType.Custom)
buttonLeft.setImage(image, forState: UIControlState.Normal)
buttonLeft.frame = CGRect(x: 0, y: 0, width: 60, height: 60)
buttonLeft.addTarget(self, action: "funcLeftAcessoryButton:", forControlEvents: UIControlEvents.TouchUpInside)
annotationView.leftCalloutAccessoryView = buttonLeft
return annotationView
希望对你有帮助
