Hi all, This is a quick and simple question - for some ridiculous reason I can't work out how it should be done properly and it couldn't be more frustrating. I'd be really grateful if someone could help me out.
Ok so I am working with MKAnnotations on my map view and want to know the * correct* (i.e. the Apple intended) way to set up my custom annotation class so that I can set the coordinate upon initialisation but also access the coordinate attribute from outside the class e.g. in my case I wish to do something like: region.center = myAnnotation.coordinate; The above gives me an error and says the assignment is between incompatible types. I've done plenty of googling and have seen a few different solutions but none of which seemed to allow me to access the coordinate. Some people define a coordinate member variable and then @property/synthesize. Others named the member variable _coordinate and then *just* synthesized it (not @property) using @synthesize _coordinate = coordinate; - I don't fully understand what that means. Finally (in the case of the MapCallouts source) others have defined a function called coordinate that returns the coordinate. I believe the last option compiled but I get the error I mentioned above. If someone could give tell me the correct solution by means of a really simple example i.e. what should go in the .h and .m (I'm only interested in the coordinate attribute for now) and then how to correctly access the coordinate attribute from outside the class for assignment e.g. the center attribute of the region object (sorry I can't remember the exact name).
