[英]How to make whole call out tappable?
I have added annotation on map and added title, leftCalloutAccessoryView (ImageView), and rightCalloutAccessoryView (UIButton), When tap on button it plays audio, I want instead of tapping on button when i will top on callout any area it starts playing audio. 我在地图上添加了注释,并添加了标题,leftCalloutAccessoryView(ImageView)和rightCalloutAccessoryView(UIButton),当点击按钮播放音频时,我想而不是点击按钮,而是要在标注顶部开始播放音频的任何地方。
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
var annotationView = mapView.dequeueReusableAnnotationViewWithIdentifier("AnnotationImage")
if annotationView == nil {
if annotation.isKindOfClass(Annotation) {
annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "AnnotationImage")
annotationView?.rightCalloutAccessoryView = self.playButton() // Custome button for rightCallOut.
annotationView?.leftCalloutAccessoryView = UIImageView(image: UIImage(named: "annotationPinImage"))
annotationView?.image = UIImage(named: "annotationPinImage.pdf")
annotationView?.canShowCallout = true
annotationView?.userInteractionEnabled = true
} else {
annotationView?.annotation = annotation
}
return annotationView
}
// Play Button methods: //播放按钮方法:
func playButton() -> UIButton {
let image: UIImage = UIImage(named: "BtnPlayAudio.pdf")!
let button: UIButton = UIButton(type: .Custom)
button.frame = CGRectMake(0, 0, image.size.width, image.size.height)
button.setImage(image, forState: .Normal)
return button
}
Thanks in advance. 提前致谢。
Add a gesture recogniser... untested, let me know if it works? 添加手势识别器...未经测试,请告知它是否有效? I used a double tap cause a single will fire too easily... 我用了两次水龙头,因为单发火太容易了。
Note the tapGestureRecognizer may need to be a class variable ultimately. 请注意,tapGestureRecognizer最终可能需要是类变量。
let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: "tapped:")
tapGestureRecognizer.numberOfTapsRequired = 2
annotationView.addGestureRecognizer(tapGestureRecognizer)
func tapped(sender: UITapGestureRecognizer)
{
print("tapped ",sender)
// play sound
}
