MKMapViewDelegate viewForAnnotation 方法

发布于 2024-11-04 02:25:05 字数 585 浏览 2 评论 0原文

我的 iPhone 上加载了一张地图，其中显示了图钉注释。我通过使用符合 MKAnnotation 协议的对象来设置这些。

现在，注释显示在模拟器上，但奇怪的是，却没有显示在设备上。仅供参考，我的两台设备都有网络连接，并且设备运行的是 iOS 3.1.3。

有什么建议吗？

对象是这样的类的实例：

@interface Point : NSObject <MKAnnotation> {
// etc...

然后将它们添加到地图视图控制器中，如下所示：

MyMapViewController *m = [[MyMapViewController alloc] initWithNibName:@"myMap" bundle:nil];
// Set up Point, thisPoint, with location info...
m.point = thisPoint;

注意，我的 viewForAnnotation 方法没有在设备上调用。它IS在模拟器上被调用（即引脚显示在模拟器上）。

原文

I have a map loading up on my iPhone which shows pin annotations. I set these up by having objects which conform to the MKAnnotation protocol.

Now, the annotations show up on the simulator but, rather bizarrely, not on the device.
FYI, I've got network connectivity on both and the device is running iOS 3.1.3.

Any suggestions?

EDIT

Objects are instances of a class like this:

@interface Point : NSObject <MKAnnotation> {
// etc...

then these are added to the Map View Controller like this:

MyMapViewController *m = [[MyMapViewController alloc] initWithNibName:@"myMap" bundle:nil];
// Set up Point, thisPoint, with location info...
m.point = thisPoint;

Note, my viewForAnnotation method is not being called on the device. It IS being called on the simulator (i.e. the pin is shown on the simulator).
