Question

Sorry I’m still a noob and just learning to program as I go and want to start out on the right foot by learning good design up front. I am using the CLLocationManager and MKReverseGecoder to get my location. In my MKReverseGecoderDelegate method, I create my annotation to show on the MKMapView. In my callout, I use a detail disclosure indicator to bring up another UITableView that displays your current address nicely as opposed to looking at the little black callout bubble.

What is a good way for my DetailViewController (the UITableView) to get the data? Do I have my first class have ivars for address, state, zipcode. In my MKReverseGecoderDelegate, set those ivars when I get that information. (The reason I would think I would need ivars is because my method to get that information in the MKReverseGeocoderDelegate is separate from the displayDetailViewController). And then do I have my DetailViewController have those same values, and when I go to display the DetailViewController, set those same variables? It seems redundant.

Any help would be greatly appreciated. Thanks!

One option

Declare custom class inheriting NSObject like

@interface YourClassName : NSObject 
{
     NSString *address;
     NSString *state;
     NSString *zipcode;
}

@property(nonatomic, retain) NSString *address;
@property(nonatomic, retain) NSString *state;
@property(nonatomic, retain) NSString *zipcode;
@end

@implementation YourClassName
@synthesize address,state,zipcode;

-(void)dealloc
{
     [super dealloc];
     [address release];
     [state release];
     [zipcode release];
}
@end


//Create object of YourClassName and set values
YourClassName *objYourClassName = [[YourClassName alloc] init];
objYourClassName.address = @"YourValue";
objYourClassName.state = @"YourValue";
objYourClassName.zipcode = @"YourValue";

Pass this object to your DetailViewController by one method after creating method like

-(void)setDetailsForDetailViewController:(YourClassName*)pObjYourClassName
{
     //self.objOfYourClassName is property declared in your detailviewcontroller.
     self.objOfYourClassName = pObjYourClassName; //You can use self.objOfYourClassName to set values in TableViewController. 
}

If you stuck any where let me know I would be glad to help you fix that.
