如下图所示，指定 100 以上的UIButton的buttonWithType:就可以得到非公开的按钮风格。 
 

其中 100 ～ 102 是 UINavigationButton 风格的按钮 
 

UIButton *button;
    button = [UIButton buttonWithType:100];
    button.frame = CGRectMake(10.0f, 10.0f, button.frame.size.width, button.frame.size.height);
    [button setTitle:[NSString stringWithUTF8String:"100 番のボタン"] forState:UIControlStateNormal];
    [self.view addSubview:button];
    button = [UIButton buttonWithType:101];
    button.frame = CGRectMake(10.0f, 50.0f, button.frame.size.width, button.frame.size.height);
    [button setTitle:[NSString stringWithUTF8String:"101 番のボタン"] forState:UIControlStateNormal];
    [self.view addSubview:button];
    button = [UIButton buttonWithType:102];
    button.frame = CGRectMake(10.0f, 90.0f, button.frame.size.width, button.frame.size.height);
    [button setTitle:[NSString stringWithUTF8String:"102 番のボタン"] forState:UIControlStateNormal];
    [self.view addSubview:button];

 

button = [UIButton buttonWithType:110];
    button.frame = CGRectMake(10.0f, 130.0f, 140.0f, 40.0f);
    [button setTitle:[NSString stringWithUTF8String:"110 番のボタン"] forState:UIControlStateNormal];
    [self.view addSubview:button];

 

button = [UIButton buttonWithType:111];
    button.frame = CGRectMake(10.0f, 180.0f, 180.0f, 40.0f);
    [button setTitle:[NSString stringWithUTF8String:"111 番のボタン"] forState:UIControlStateNormal];
    [self.view addSubview:button]; button = [UIButton buttonWithType:111];
    button.frame = CGRectMake(10.0f, 230.0f, 180.0f, 40.0f);
    [button setTitle:[NSString stringWithUTF8String:"111 番のボタン"] forState:UIControlStateNormal];
    [button setTintColor:[UIColor redColor]];
    [self.view addSubview:button]; button = [UIButton buttonWithType:111];
    button.frame = CGRectMake(10.0f, 280.0f, 180.0f, 40.0f);
