Try this
NSString *str=[[arrInitiatives valueForKey:#"FileName"] objectAtIndex:0];

Answer 2

When you create the str variable with code
NSString *str=[arrInitiatives valueForKey:#"FileName"];
In fact it doesn't return NSString object but NSArray object. That's why filename is inside parenthesis in log:
file name ----> (
"Lighthouse4908.jpg"
)
If you're sure that filename will always be present in the array you can try what #Amit Kalghatgi suggested in his answer.
The problem is that when this array is empty you will get an error during execution of this code. I would rather do something like this:
NSArray *filenames = [arrInitiatives valueForKey:#"FileName"];
NSString *str = nil;
if (filenames.count) {
str =[arrInitiatives valueForKey:#"FileName"];
}
NSLog(#"file name ----> %#",str);
Of course before creating imageUrl you'll have to check if str is nil or not.
