Answer 2

// Rename the file, by moving the file
//Ex rename file1 to file2 use this code


NSError *error = nil;
    NSFileManager *filemgr = [[NSFileManager alloc] init];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"file1.txt"];

NSString *filePath2 = [documentsDirectory stringByAppendingPathComponent:@"file2.txt"];

// Attempt the move
if ([filemgr moveItemAtPath:filePath toPath:filePath2 error:&error] != YES){
    NSLog(@"Unable to move file: %@", [error localizedDescription]);
}
