Question

I have a dictionary with key-value pair populated from JSON returned data.What I wish to do is use the dictionary to populate UITableView.

I have this structure for table:

[Product Name]
By [Manufacturer Name]

What this means is that key is Product Name and Value is Manufacturer Name. I need to get the name of the key and the name of the value. How can this be done? and is it possible without for-loop?

Answer 1

I’d use the enumerateKeysAndObjectsUsingBlock: method. The following code builds a list of the strings you require.

NSMutableArray *names = [NSMutableArray array];

[dictionary enumerateKeysAndObjectsUsingBlock: ^(NSString *key, NSString *object, BOOL *stop) {
    [names addObject[NSString stringWithFormat:@"%@ By %@",key, object]];
}];
