    [aBtn setImage:[UIImage imageNamed:@"A"] forState:UIControlStateNormal];

    [aBtn setTitle:@"A" forState:UIControlStateNormal];
    [aBtn setTitleColor:[ UIColor blackColor] forState:UIControlStateNormal];
    [aBtn setTitleColor:[ UIColor whiteColor] forState:UIControlStateHighlighted];
    [aBtn addTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];
