如何将自定义按钮/ MapPin添加到MKAnnotation？

Question

我是iphone的开发noob，我试图添加一个自定义按钮到注释标注。添加常规按钮到rightCalloutAccessoryView没有问题，但它不适用于自定义样式。我的图像大小是32 x 32.我也想添加一个自定义地图针在这个计算器问题here任何帮助，非常感谢。

MY CODE

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { 
// Define your reuse identifier. 
static NSString *identifier = @"MapPoint"; 

if ([annotation isKindOfClass:[MapPoint class]]) { 
    MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier]; 
    if (annotationView == nil) { 
     annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier]; 
    } else { 
     annotationView.annotation = annotation; 
    } 
    annotationView.enabled = YES; 
    annotationView.canShowCallout = YES; 
    annotationView.animatesDrop = YES; 
    annotationView.image = [UIImage imageNamed:@"myimage.png"]; 

    UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    //UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; 
    [rightButton setImage:[UIImage imageNamed:@"phony2.png"] forState:UIControlStateNormal]; 
    [rightButton addTarget:self 
        action:@selector(showDetails:) 
      forControlEvents:UIControlEventTouchUpInside]; 
    annotationView.rightCalloutAccessoryView = rightButton; 

    return annotationView; 
} 
return nil;  

}

Answer 1

[rightButton addTarget:self 
       action:@selector(showDetails:) 

卸下按钮

[rightButton setFrame:CGRectMake(0,0,32,32)]; 

的这条线 并设置框架，并从打浇口方法中的轻击动作

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

您在哪里获得注释视图。

希望这会帮助你。
