推荐答案
尝试使用以下Map View的委托方法。您可以将右侧呼出配件视图设置为按钮
Try using following delegate method of Map View. You can set right call out accessory view as button
- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation{
MKAnnotationView *view = nil;
//MKPinAnnotationView *view=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"HotSpotsLoc"];
if(annotation !=mapView.userLocation){
view = (MKAnnotationView *)
[mapView dequeueReusableAnnotationViewWithIdentifier:@"identifier"];
if(nil == view) {
view = [[[MKAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:@"identifier"]
autorelease];
}
ParkPlaceMark *currPlaceMark = annotation;
NSLog(@"%i",currPlaceMark.position);
view.image = [UIImage imageNamed:@"pin.png"];
UIButton *btnViewVenue = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
view.rightCalloutAccessoryView=btnViewVenue;
view.enabled = YES;
view.canShowCallout = YES;
view.multipleTouchEnabled = NO;
//view.animatesDrop = YES;
}
return view;
}
