我有一个只有一个注释的地图.我创建了一个简单的类,我希望它在用户点击注释时显示.问题是当我点击注释时没有任何反应.

这是我的代码:

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark{
    NSLog(@"Reverse Geocoder completed");
    mPlacemark=placemark;
    [mapView addAnnotation:placemark];
}

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{
    MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"];
    annView.animatesDrop=TRUE;

    //create UIButton for annotation
    UIButton *detailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    //NSInteger annotationValue = [self.annotations indexOfObject:annotation];

    [detailButton addTarget:self action:@selector(showDetailView:) forControlEvents:UIControlEventTouchUpInside];
    annView.rightCalloutAccessoryView=detailButton;
    return annView;
}


-(void)showDetailView:(id)sender{
    NSLog("inside the stupid method");
    MyDetailViewController *detailView=[[MyDetailViewController alloc] initWithNibName:@"MyDetailViewController" bundle:nil];
    [[self navigationController] pushViewController:detailView animated:YES];
    [detailView release];
}

我的showDetailView功能永远不会被调用.请帮助我.我是iphone的新手,我可能会忘记一件简单的事情.谢谢

还是行不通!!!!

我在我的应用程序中有一个mapView,我正在使用我自己的图像作为MKAnnotationView,这是pin图像.这是我设置它的代码.

-(RMAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(RentPin *)annotation{

    static NSString *identifier = @"MyLocation";

    if ([annotation isKindOfClass:[RentPin class]]) {
        RMAnnotationView *annotationView = (RMAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];

        if(annotationView == nil){
            annotationView = [[RMAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
            annotationView.enabled = YES;
            annotationView.canShowCallout = NO;
            annotationView.image = [UIImage imageNamed:@"home44.png"];
            annotationView.centerOffset = CGPointMake(-10, -10);
        }else{
            annotationView.annotation = annotation;
        }

        return annotationView;
    }
    return nil;
}

它工作正常,自定义图像也正常显示,但当我捏mapView以放大/缩小地图时,我注意到自定义图像在地图上失去了准确性.请看下面的图片.

https://www.dropbox.com/s/irrgmohppf08fzr/image1.png 此图显示引脚位于此位置,非常准确.

https://www.dropbox.com/s/vvlr4ckk6molqd7/image2.png 缩小mapView后,针脚穿过街道,显示该地址在湖中....

(对不起链接,因为由于声誉不足而无法发布图片.)

有人可以帮我这个吗？我的图像是44x44,我也尝试设置引脚的centerOffset,它无法在所有缩放级别动态解决这个问题.
