问题描述
当选中附件按钮时，我需要传递itemId，这样我就可以识别要传递给我的详细视图的项目。
When tabbing the accessory button, i need to pass the itemId, so i can identify the item to pass on to my detail view.
到目前为止：
添加注释：
for (id row in self.detailItem) {
Item *i = (Item *) row;
CLLocationCoordinate2D destination;
destination.latitude = (double) i.latitude;
destination.longitude = (double) i.longitude;
//i.itemid
MapViewAnnotation *destinationAnnotation = [[MapViewAnnotation alloc] initWithTitle: i.name andCoordinate: destination];
[self.mapView addAnnotation: destinationAnnotation];
[destinationAnnotation release];
}
添加配件按钮
- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation
{
MKPinAnnotationView *pinAnnotation = nil;
if(annotation != mapView.userLocation)
{
static NSString *defaultPinID = @"myPin";
pinAnnotation = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if ( pinAnnotation == nil )
pinAnnotation = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
pinAnnotation.canShowCallout = YES;
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinAnnotation.rightCalloutAccessoryView = infoButton;
}
return pinAnnotation;
}
找到要传递给详细视图的项目
find the item to pass to detail view
-(void)mapView:(MKMapView *)mapView annotationView:(MKPinAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
// get annotation details here.
NSLog(@"%@", control);
}
推荐答案
添加 itemid 属性为 MapViewAnnotation 类。
添加注释时，请设置调用之前的属性 addAnnotation ：
When adding the annotation, set the property before calling addAnnotation:
destinationAnnotation.itemid = i.itemid;
[self.mapView addAnnotation: ...
在中calloutAccessoryControlTapped ，访问注释详细信息如下：
In calloutAccessoryControlTapped, access the annotation details like this:
MapViewAnnotation *annotationTapped = (MapViewAnnotation *)view.annotation;
NSLog(@"annotationTapped.itemid = %@", annotationTapped.itemid);
（如果 itemid 将是 int ，将NSLog中的％@ 更改为％d 。 ）
(If itemid will be an int, change the %@ in the NSLog to %d.)
