Back on iterating through a mapKit annotation array, I'm bending my brain cell
on this one.
All my annotations are instances of the MyLocation class
I added a method to expose the properties I want to save by returning a dict to
the class.
After all annotations are added, and I want to walk the array and build an
array of annotations, I do this:
- (IBAction)saveData:(id)sender
{
for (NSDictionary * myAnnotation in self.mapView.annotations)
{
MyLocation *tempLocation = [[MyLocation alloc] init ];
// test that the methods in the MyLocation objects
actually work on an empty object
NSString *myString = [tempLocation name];
NSDictionary *myDict = [tempLocation
returnCoordinatesInDict];
NSDictionary *myStuffDict = [tempLocation
returnPropertiesInDict];
// Try it with one of the MyLocation objects in the
annotation array
NSDictionary *myGoodsDict = [myAnnotation
returnPropertiesInDict];
Xcode will not let the last line compile with a "Receiver type 'NSDictionary'
for instance message does not declare a method with selector
'returnPropertiesInDict'
But if I comment out that line, set a breakpoint, it clearly shows that
myAnnotation is a myLocation instance just like tempLocation.
Does anyone know what I am missing here?
Thanks,
- Alex
