Can I read just the key from plist?

Question

Can I read just the key from plist without its value, also if I know the value can I read the key ?

Answer 1

Reading .plist:

NSString *path = [[NSBundle mainBundle] pathForResource:@"myPlist" ofType:@"plist"];    
NSMutableDictionary *myDictionary = [[NSMutableDictionary alloc] initWithContentsOfFile:path];

Getting all keys and all values:

NSArray* allmyKeys = [myDictionary  allKeys];
NSArray* allmyValues= [myDictionary  allValues];

Getting all keys for an values object:

NSArray* allmyKeys = [myDictionary  allKeysForObject:myValueObject];

Answer 2

As an alternative, you can use allKeysForObject: method which returns,

A new array containing the keys corresponding to all occurrences of anObject in the dictionary. If no object matching anObject is found, returns an empty array.

From that array you can get the key by invoking the objectAtIndex: method.
