Create NSString from strings within a dictionary

Question

I have an NSDictionary where both the keys and values are NSStrings and I'd like to create one NSString from them in the form of

Key1: Value1
Key2: Value2

What is the best method of doing this?

Answer 1

Lets assume your dictionary is called myDict and key is the value of the key you are looking for

[NSString stringWithFormat:@"%@: %@", key, [myDict objectForKey: key]];

This will return

Key: Value

Of course if this is just for you logging on the console you can make life easier for yourself and do something like

NSLog(@"%@", [myDict description]);

Edit::

To display the entire dictionary you can use a for each loop thusly:

NSMutableString *finalString = [NSMutableString string];

for(NSString *key in [myDict allKeys]){

    [finalString appendFormat:@"%@: %@\n", key, [myDict objectForKey: key]];

}
