如何呈现带有UIView、UIButton子类的视图控制器？

@property (nonatomic, strong) UIView *customView;
@property (nonatomic, strong) UIButton *customButton;

- (void)viewDidLoad {
    [super viewDidLoad];
    
    // 创建自定义视图
    self.customView = [[UIView alloc] initWithFrame:CGRectMake(50, 50, 200, 200)];
    self.customView.backgroundColor = [UIColor redColor];
    [self.view addSubview:self.customView];
    
    // 创建自定义按钮
    self.customButton = [UIButton buttonWithType:UIButtonTypeSystem];
    self.customButton.frame = CGRectMake(50, 300, 200, 50);
    [self.customButton setTitle:@"Click Me" forState:UIControlStateNormal];
    [self.customButton addTarget:self action:@selector(buttonClicked) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:self.customButton];
}

- (void)buttonClicked {
    // 按钮点击事件处理
    NSLog(@"Button Clicked");
}

CustomViewController *customVC = [[CustomViewController alloc] init];
[self presentViewController:customVC animated:YES completion:nil];
