Question

I have an NSArray of NSDictionary.
Each dictionary in the array has three keys: ‘Name’, ‘Sex’ and ‘Age’

How can I find the index in NSArray of NSDictionary where, for example, Name = 'Roger'?

Answer 1

    NSUInteger count = [array count];
    for (NSUInteger index = 0; index < count; index++)
    {  
        if ([[[array objectAtIndex: index] objectForKey: @"Name"] isEqualToString: @"Roger"])
        {  
            return index;
        }   
    }
    return NSNotFound;
