Check if String contains any String from array

Question

I know I can check if a string contains another string like this

NSString *string = @\"hello bla bla\";
if ([string rangeOfString:@\"bla\"].location == NSNotFoun

There you go:

NSArray* arrRet = [myArray filteredArrayUsingPredicate:[NSPredicate predicateWithBlock:^BOOL(id  __nonnull evaluatedObject, NSDictionary * __nullable bindings) {
    for(NSString* val in valuesArray) {
        if ([evaluatedObject rangeOfString:val].location != NSNotFound)
            return true;
    }
    return false;
}]];

arrRet contains exactly the two desired strings.

A little bit more magic later you have your code without writing a loop :P

NSArray* arrRet = [myArray filteredArrayUsingPredicate:[NSPredicate predicateWithBlock:^BOOL(id  evaluatedObject, NSDictionary * bindings) {
    BOOL __block match = false;
    [valuesArray enumerateObjectsUsingBlock:^(id  __nonnull obj, NSUInteger idx, BOOL * __nonnull stop) {
        *stop = match = [evaluatedObject rangeOfString:obj].location != NSNotFound;
    }];
    return match;
}]];
