ios - 在没有 IBOutlet 的情况下将 IBAction 与 UIButton 一起使用

Question

抱歉标题不清楚。我希望能够将 IBAction 方法添加到按以下方式添加的按钮:

(.h类)

{
    UIButton *button;
}
-(IBAction)ButtonReleased:(id)sender

(.m类)

{
    -(IBAction)ButtonReleased:(id)sender
    {
        //Actions done by button pointer
    }

    - (void)viewDidLoad
    {
        [super viewDidLoad];
        [PlayButton setFrame:CGRectMake(10, 10, 100, 50)];
        [PlayButton setTitle:@"PlayButton" forState:UIControlStateNormal];
        [self.view addSubview:PlayButton];
    }
}

问题是，如何将 UIButton 按钮操作(例如 TouchUpInside)连接到 ButtonReleased 方法。

Answer 1

[button addTarget:self action:@selector(ButtonReleased:) forControlEvents:UIControlEventTouchUpInside];
