Adding NSURL to a mutable array in xcode

Question

I have a for loop,it contacts an array of strings to a part of a URL and then converts it to NSURL and pushes them one by one inside a mutablearray. The problem is that the mutableArray is null when i NSlog it outside the for loop. Here is the code:

for (int i = 0; i < news_Image.count; i++) {
    concatURLS = [mediaURL stringByAppendingString:
    [news_Image objectAtIndex:i]];
    url = [NSURL URLWithString:concatURLS];
    [urlArrays addObject:url];        
}

Post the code for creating the array.

Do you ever allocate the mutable array?

You need to make sure that you are calling:

 NSMutableArray * urlArrays = [[NSMutableArray alloc] init];

before the for loop.

Also, make sure news_image has been allocated as well.
