Question

Basically I have an NSMutableArray of NSDictionaries stored to NSUserDefaults.

I have implemented tableview into my app but I am not sure how to display the individual values. I know that I am not providing much information (such as the keys I used) but could anyone give me a basic example on how access the values stored in NSDictionaries?

The code below doesn’t work obviously, but if it were just a string it would be accessible in this way:

cell.textLabel.text = [[NSUserDefaults standardUserDefaults] objectForKey:@"parked locations"];

Answer 1

If you stored mutable arrays in, you can access the NSMutableArray with the key @"parked locations" :

NSMutableArray *parkedLocations = [[NSUserDefaults standardUserDefaults]
                                   objectForKey:@"parked locations"];

Each element of that array is a NSDictionary you access like that :

NSDictionary *parkedLocation = [parkedLocations objectAtIndex:0]; // the first

Finally inside each dictionary, access values like, for example NSString :

NSString *locationName = [parkedLocation objectForKey:@"theKeyForTheName"];

As NSUserDefaults can store objects of type : NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary, yes, if it were just a string, you could access it like you wrote.
