在iOS中显示按钮而不是地图上的图钉

Question

我使用MKMapView在MKMapView上显示注释，但现在我想显示自定义注释而不是默认地图引脚。

我怎么能这样做？？

Answer 1

试试这个：

- (MKAnnotationView *)mapView:(MKMapView *)mapView 
        viewForAnnotation:(id<MKAnnotation>)annotation {
        MKAnnotationView *annView = (MKAnnotationView *)[mapView 
                dequeueReusableAnnotationViewWithIdentifier: @"pin"];
        if (annView == nil) {
            annView = [[[MKAnnotationView alloc] initWithAnnotation:annotation 
                          reuseIdentifier:@"pin"] autorelease];

            annView.frame = CGRectMake(0, 0, 200, 50);

            UIButton *pinButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
            pinButton.frame = CGRectMake(0, 0, 140, 28);
            pinButton.tag = 10;

            UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] 
                initWithTarget:self action:@selector(handlePinButtonTap:)];
            tap.numberOfTapsRequired = 1;
            [pinButton addGestureRecognizer:tap];

            [annView addSubview:pinButton]; 
        }

        annView.annotation = annotation;

        UIButton *pb = (UIButton *)[annView viewWithTag:10];
        [pb setTitle:annotation.title forState:UIControlStateNormal];

        return annView;
}

- (void) handlePinButtonTap:(UITapGestureRecognizer *)gestureRecognizer {
    // Your tap action goes here
}

我怎么能这样做？？

停止使用MKPinAnnotationView，而是创建自己的MKAnnotationView子类。
