Question

所有权不明。我愿以以下方式在一顿添加“国际行动”方法:

(h)类

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

(m)

{
    -(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,我如何将UIButton纽顿行动(say, TouchUpInside)与ButtonReleased方法联系起来。

Answer 1

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