Either of these would do...

public static boolean arrayContainsSubstring( NSArray< String > array, String substring )
{
if ( array == null || substring == null || array.count() == 0 )
return false;
return array .componentsJoinedByString ( "|" ).toLowerCase().indexOf( substring.toLowerCase() ) >= 0;
}


// or (perhaps more efficient)

public static boolean arrayContainsSubstring( NSArray< String > array, String substring )
{
if ( array != null && array.count() > 0 && substring != null )
{
String lowerSub = substring.toLowerCase();
for ( String item : array )
if ( item.toLowerCase().indexOf( lowerSub ) >= 0 )
return true;
}
return false;
}

Oh, I was referring to your substring routine...

In this specific instance i was looking for intersecting strings from two arrays.


Nevertheless, I'm always curious to see how people solve various problems, so if you're willing to share, please pass along a code snippet.

NSArray first, second; //assume they exist and contian your strings

NSSet firstSet = new NSSet(first);
NSSet secondSet = new NSSet(second);
NSSet intersectingsSet = firstSet.setByIntersettingSet(secondSet);

NSArray myIntersectedArray = intersectingsSet.allObjects();


TIA.

Are you looking for a substring of a string in an array? Or are you looking for the whole string? I have written a routine to find the substring of a string in an array, if that would help.
