在我的应用我去取coredatabase，并把结果放到一个数组称为self.stores。 我转换的商店位置，其有一个距离属性MyLocation对象。 我绘制像这样的MyLocation对象：
- (void)plotStorePositions:(NSString *)responseString {
for (id<MKAnnotation> annotation in _mapView.annotations) {
[_mapView removeAnnotation:annotation];
}
//CYCLE THRU STORE OBJECTS
for (Store * storeObject in self.stores) {
NSString * latitude = storeObject.latitude;
NSString * longitude = storeObject.longitude;
NSString * storeDescription = storeObject.name;
NSString * address = storeObject.address;
//CREATE MYLOCATION OBJECTS
CLLocationCoordinate2D coordinate;
coordinate.latitude = latitude.doubleValue;
coordinate.longitude = longitude.doubleValue;
MyLocation *annotation = [[MyLocation alloc] initWithName:storeDescription address:address coordinate:coordinate distance:0];
//CREATE A PIN FOR EACH MYLOCATION ANNOTATION
CLLocation *pinLocation = [[CLLocation alloc] initWithLatitude:annotation.coordinate.latitude longitude:annotation.coordinate.longitude];
//SET USERLOCATION (Must move this code out)
self.userLocation = [[CLLocation alloc] initWithLatitude:self._mapView.userLocation.coordinate.latitude longitude:self._mapView.userLocation.coordinate.longitude];
//SET USERLOCATION TO APPDELEGATE (Must move this code out)
AppDelegate *myDelegate = [[UIApplication sharedApplication] delegate];
myDelegate.userLocation = self.userLocation;
//CALCULATE DISTANCE AND SET ITS THAT MYLOCATION's DISTANCE PROPERTY
CLLocationDistance calculatedDistance = [pinLocation distanceFromLocation:userLocation];
annotation.distance = calculatedDistance/1000;
[_mapView addAnnotation:annotation];
}
}
这是在MapView。 然后，我有一个tableview中，我获取相同的coredatabase，并再次获得self.stores。 然后，我循环self.stores创建STORE storeObjects进行阵列投入到我的tableview细胞。 但我想这些细胞进行排序。 我如何获得这应该是在内存中MyLocation对象？ 我需要将它们传递到的appDelegate或到的tableview控制器？
