问题描述

这是我的-mapView:viewForAnnotation方法，当我创建注释视图时，该方法会掉线.但是，当我在-viewDidLoad中设置mapView.showsUserLocation = YES;时，我会掉到无限循环上的引脚上(预期-在模拟器中)，而不是正常的蓝点.

This is my -mapView:viewForAnnotation method which drops pins when i create annotation views. But when i set mapView.showsUserLocation = YES; in -viewDidLoad, i get a pin dropped on Infinite Loop (expected - in simulator) and not the normal blue dot.

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{
     MKAnnotationView *anno = nil;
     //create a pin annotation view
MKPinAnnotationView  *pin=[[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"pin"]autorelease];

    [pin setPinColor:MKPinAnnotationColorRed];
    pin.animatesDrop=YES;
    pin.canShowCallout = YES;
    pin.calloutOffset = CGPointMake(-5, 5);
    anno = pin;
    return anno;
}

我怎样才能让它掉针并显示蓝点?

How can i get it to drop pins and show the blue dot as well?

谢谢

推荐答案

确实很容易修复，尽管不确定这是否是正确的方法...

Really simple to fix, although unsure if this is the correct way to do it...

if (annotation == mapView.userLocation){
    return nil; //default to blue dot
}
