Question

I have an array like this:

self.youtubeVideos = [NSArray arrayWithObjects: 

                      @"http://example.com/index.php?number=1&keyword=", 
                      @"http://example.com/index.php?number=2&keyword=",

                      nil];

I would like to add a NSString called “searchKeyword” to the end of every object in the array.

How do I do this?

Thanks!

Make a mutable array, then step through and modify each element as you go along.

NSMutableArray* fixedUrls = [NSMutableArray arrayWithCapacity:self.youtubeVideos.count];    

for (NSString* url in self.youtubeVideos)
{
    [fixedUrls addObject:[url stringByAppendingString:searchKeyword]];
}

self.youtubeVideos = fixedUrls;
