如何从plist加载纬度经度？

Question

我想在plist中添加纬度和经度，并希望在地图视图中显示位置。 我无法在plist中加载纬度和经度。

NSString *path = [[NSBundle mainBundle] pathForResource:@"map" ofType:@"plist"];
NSArray *anns = [NSArray arrayWithContentsOfFile:path];
NSLog(@"anns=%@",anns);

for(NSMutableDictionary *note in anns) {
    float realLatitude = [[note objectForKey:@"latitude"] floatValue];
    float realLongitude = [[note objectForKey:@"logitude"] floatValue];
    WHLocationAnnotation* myAnnotation = [[WHLocationAnnotation alloc] init];
    CLLocationCoordinate2D theCoordinate;
    theCoordinate.latitude = realLatitude;
    theCoordinate.longitude = realLongitude;
    NSLog(@"...abc...%f",[[note objectForKey:@"latitude"] floatValue]);
         myAnnotation.title = [note objectForKey:@"Title"];
    myAnnotation.subtitle = [note objectForKey:@"subtitle"];

    [mapViewForAnnotation setDelegate:self];
    [mapViewForAnnotation addAnnotation:myAnnotation];

}

}

我在viewdidload中完成了这个。我使用nslog获取经度，但mapview上的位置不正确。
