地图查看详细查看使用列表

Question

我目前正在使用plist在地图上放置注释，我设法做到这一点，但即时通讯现在有问题试图从地图视图转到详细视图并从plist中携带信息。

我已经设置了plist，因此它在mapview中有标题和副标题，然后我设置了一个孩子，并且这转到了信息即时消息，试图在详细视图中访问。

我已经设法让它进入详细视图，但它没有采取任何信息，因为我无法解决所需的代码。

我希望这一切都有道理，因为我有点困惑自己。感谢您对任何人的帮助，在此，你将是一个生命的救星（在某种程度上）

我假设MyAnnotation类包含有关您需要的注释的所有信息。
它来自plist的事实在这一点上是无关紧要的。

首先，在ViewController2，添加属性为注释：

@property (nonatomic, retain) MyAnnotation *annotation; 

接下来，在calloutAccessoryControlTapped委托方法，设置属性：

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control 
{ 
    NSLog(@"tapped"); 
    ViewController2 *dvController = [[ViewController2 alloc] initWithNibName:@"ViewController2" bundle:[NSBundle mainBundle]]; 

    dvController.annotation = (MyAnnotation *)view.annotation; 

    [self.navigationController pushViewController:dvController animated:YES]; 
} 

在ViewController2，你现在可以使用annotation属性来配置显示。
