自定义 MKAnnotationView，在地图上显示标题/副标题位置

Question

1) 我的注释显示了not的标题和副标题。 我已经尝试了很多，但我不能。

2) 如果选择了注释，则注释将位于窗口中间。所以地图被移动了。有什么想法吗？

3) 我的 Callout 按钮不再起作用，我有 @ selector (openAnything) 但我想使用此功能被触发 - (void) mapView: (MKMapView *) mapView annotationView: (MKAnnotationView *) view calloutAccessoryControlTapped: (UIControl *) control {

问够了，这里有一个视频和一些源代码 http://www.youtube.com/watch?v=Ur1aqeYEFHw&feature=youtube_gdata_player

谢谢

Answer 1

你的注解类需要有subtitle属性，你的有subTitle。

如果calloutAccessoryControlTapped 没有被调用，这通常表明您的 MKMapview 的委托尚未设置。但是，您仅在选择附件按钮时才对其进行设置。你有充分的理由吗？由于标注窗口在被选中之前是不可见的，我建议您在viewForAnnotation 中设置附件按钮，并在标注窗口出现时让它出现。

Answer 2

我修复了第一个：

    TAPPMapAnnotation *theAnnotation = (TAPPMapAnnotation *)self.annotation;
    self.title           = [[UILabel alloc]init];
    self.title.font      = [UIFont systemFontOfSize:12.0];
    self.title.textColor = [UIColor whiteColor];
    self.title.backgroundColor = [UIColor clearColor];

    self.title.text      = theAnnotation.title;
    [...]
    [self.theView addSubview:self.title];
