如何切換到iPhone SDK中的MKMapView中的註釋針點擊另一個視圖？

Question

1。我正在使用的MKMapView多針，我想在挖掘管腳的下一個視圖中顯示詳細

#import "mapViewController.h" 
#import "displaymap.h" 
#import "second.h" 

@implementation mapViewController 
@synthesize mapview; 
@synthesize selectedAnnotationsl; 



- (void)viewDidLoad { 
[super viewDidLoad]; 

[mapview setMapType:MKMapTypeStandard]; 
[mapview setZoomEnabled:YES]; 
[mapview setScrollEnabled:YES]; 
MKCoordinateRegion region={{0.0,0.0},{0.0,0.0}}; 
region.center.latitude=22.292189; 
region.center.longitude=70.792207; 
region.span.longitudeDelta=0.01f; 
region.span.latitudeDelta=0.01f; 
[mapview setRegion:region animated:YES]; 


    //[mapview setDelegate:self]; 

displaymap *ann=[[displaymap alloc]init]; 
ann.title=@"alpesh"; 
ann.subtitle=@"Mahatma Gandhi"; 
ann.coordinate = region.center; 
[mapview addAnnotation:ann]; 

region.center.latitude=22.295031; 
region.center.longitude=70.790837; 
region.span.longitudeDelta=0.01f; 
region.span.latitudeDelta=0.01f; 
displaymap *bnn=[[displaymap alloc]init]; 
bnn.title=@"samir"; 
bnn.subtitle=@"Mahatma Gandhi"; 
bnn.coordinate = region.center; 
[mapview addAnnotation:bnn]; 

//selectedAnnotationsl =[[NSArray alloc]initWithObjects:bnn.title,ann.title,nil]; 
} 


-(MKAnnotationView *)mapview:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation 
{ 
MKPinAnnotationView *pinView=nil; 
if(annotation != mapview.userLocation) 
{ 
    static NSString *defaultPinID = @"com.invasivecode.pin"; 
    pinView=(MKPinAnnotationView *)[mapview dequeueReusableAnnotationViewWithIdentifier:defaultPinID]; 

    if(pinView==nil)pinView=[[[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:defaultPinID]autorelease]; 
    pinView.pinColor=MKPinAnnotationColorRed; 
    pinView.canShowCallout=YES; 
    pinView.animatesDrop=YES; 
    pinView.calloutOffset= CGPointMake(-5, 5); 
} 
else 
{ 
    [mapview.userLocation setTitle:@"I am here"]; 

} 
return pinView; 
} 




- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { 

MKPinAnnotationView *annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; 
UIButton *addButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; 
[addButton addTarget:self action:@selector(changepage:) forControlEvents:UIControlEventTouchUpInside]; 
[annView setPinColor:MKPinAnnotationColorRed]; 
annView.rightCalloutAccessoryView = addButton; 
annView.animatesDrop = TRUE; 
annView.canShowCallout = YES; 

return annView; 

} 



-(IBAction)changepage:(UIView*)sender 
{ 
second *s = [[second alloc]initWithNibName:@"second" bundle:nil]; 
s.title = @"samir"; 
[[self navigationController] pushViewController:s animated:YES]; 
} 

Answer 1

MKMapViewDelegate的calloutAccessoryControlTapped：方法是你所需要的。您無需爲addButton添加目標和操作。如果點按標註附件控件（左側和右側附件控件），則會調用此委託方法。

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { 

    // Your code here 
}
