MKMapView MKAnnotationView ISSUE? [英] MKMapView MKAnnotationView ISSUE?
问题描述
我有一个带引脚的地图视图,当用户选择一个引脚时,它会转到该引脚的详细信息屏幕。我还有一个表视图,当用户选择一个项目时,它会进入相同类型的详细信息视图。
I have a map view with pins that when the user selects a pin it goes to a detail screen for that pin. I also have a table view that when the user selects an item it goes to the same type detail view.
我在mapview中通过数组添加多个引脚。我已经在附件视图中添加了按钮,
I am adding the multiple pins in mapview through array. I have added button to the accessory view,
这是问题...
当我点击按钮时引脚选择将他带到不同引脚的详细视图。但是在表格视图中它仍然可以正常工作。任何人都可以帮助我...?
when I tap the button pin selection takes him to the detail view for a different pin. But in the table view it still works fine..anyone pls help me with this...?
-(MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation
{
MKPinAnnotationView *newAnnotation = nil;
if([annotation.title isEqualToString:@"You are here."])
{
newAnnotation = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"greenpin"];
newAnnotation.pinColor = MKPinAnnotationColorGreen;
}
else
{
newAnnotation = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"redpin"];
newAnnotation.pinColor = MKPinAnnotationColorRed;
UIButton *pinButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinButton.tag = indexvar;
[newAnnotation addSubview:pinButton];
newAnnotation.canShowCallout = YES;
newAnnotation.rightCalloutAccessoryView = pinButton;
newAnnotation.calloutOffset = CGPointMake(-5, 5);
indexvar++;
return newAnnotation;
[pinButton release];
}
newAnnotation.animatesDrop = YES;
newAnnotation.canShowCallout = YES;
return newAnnotation;
}
- (void)mapView:(MKMapView *)wikiMapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSInteger selectedIndex = ((UIButton *)control).tag;
NSLog(@"Property Index : %d ",selectedIndex);
DetailView = [[PropertyDetails alloc] initWithNibName:@"PropertyDetails" bundle:nil];
DetailView.propertyReference = [PropertyReferenceArr objectAtIndex:selectedIndex];
DetailView.propertyTitle = [propertyTitlesArr objectAtIndex:selectedIndex];
DetailView.propertyPrice = [propertyPriceArr objectAtIndex:selectedIndex];
DetailView.propertyBedrooms = [propertyBedroomsArr objectAtIndex:selectedIndex];
DetailView.propertyLatitude = [propertyLatitudesArr objectAtIndex:selectedIndex];
DetailView.propertyLongitude = [propertyLongitudesArr objectAtIndex:selectedIndex];
DetailView.propertyDefaultImage = [PropertyImageArr objectAtIndex:selectedIndex];
DetailView.propertyStatusId = [PropertyStatusArr objectAtIndex:selectedIndex];
[self.navigationController pushViewController:DetailView animated:YES];
[DetailView release];
}
推荐答案
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
myAnnotation *annView = view.annotation; // myAnnotation is my custom class for annotations
// now in annView you have the exact annotation whose accessorybutton is clicked now you can do whatever you want with it.
NSLog(@"title = %@",annView.title);
}
然后设置按钮标签,您可以使用注释的标题或副标题进一步的比较或任何你想要的
Rather then setting the button tag you can use the title or subtitle of the annotation for futher comparision or whatever you want
在你的代码中使用
[newAnnotation addSubview:pinButton]; // i think this is wrong you should only add it to accessory view
