我似乎无法在地图视图中弹出我的注释。我有一个来自plist的大量注释，除了一个之外，他们没有出现在地图上。请帮忙吗？

我无法回复评论，因此我将其作为答案发布

您可以使用以下方法为注释添加属性：

 -(MKAnnotationView *) mapView:(MKMapView *)mapMKMapView viewForAnnotation:       (id<MKAnnotation>)annotation
{
MKPinAnnotationView *MyPin=[[MKPinAnnotationView alloc] initWithAnnotation:annotation       reuseIdentifier:@"current"];
MyPin.pinColor = MKPinAnnotationColorPurple; // <--for coloring purpose 

UIButton *adverButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[adverButton addTarget:self action:@selector(button:)forControlEvents:UIControlEventTouchUpInside];

MyPin.rightCalloutAccessoryView = adverButton;
MyPin.draggable = YES;
MyPin.highlighted = YES;
MyPin.animatesDrop  = TRUE;
MyPin.canShowCallout  = YES;

return MyPin;
}

-(void)button:(id)sender
{
  //add your nextView you want to open here
}
