请教NSArray的替换

有一组数组数据(addfd, 234243, sdfdsafdsf, 2323432432...)分别对应的标题是(标题7, 标题x, 标题4, 标题k...)通过下面代码将内容替换为标题- (NSArray *){NSArray *contentLIST = [[NSArray alloc] init];contentLIST = [fileManager contentsOfDirectoryAtPath:documentDir error:&error]; for (int i = 0; i < [contentLIST count]; i++) { NSString *item = [contentLIST objectAtIndex:i]; NSLog(@"title is%@",[self replaceWithTitle:item]); }NSArray *titleList = [[NSArray alloc] init];titleList = //请问这里怎么写？ return titleList;}请教如何返回为标题的数组？

替换可以用- (void)replaceObjectAtIndex:(NSUInteger)index withObject:(id)anObject
