- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
NSLog(@"I'm Working");
static NSString *identifier = @"MyLocation";
if ([annotation isKindOfClass:[userPins class]]) {
userPins *location = (userPins *) annotation;
MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [_mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
if ([location.name compare:@"LARCENY"] == NSOrderedSame) {
annotationView.pinColor = MKPinAnnotationColorGreen;
}
return annotationView;
}
return nil;
}
此代码不起作用。我正在从JSON添加图钉。我看到红色的针脚,但看不到nslog(我在工作)。有任何想法吗?
最佳答案
您需要在viewDidLoad或笔尖或创建它的任何位置设置mapView的委托。
关于objective-c - MKAnnotationView没什么,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/7597829/
