禁用 IBAction 链接按钮

发布于 2024-11-24 03:11:43 字数 479 浏览 2 评论 0原文

我使用 Interface Builder 创建了一个按钮并将其链接到一个操作。我想禁用下面 if 语句中的 hit 按钮。

- (IBAction)hit:(id)sender {
    Application *app = [[Application alloc] init];
    int nc = [app dealCard];
    [userOne setIntValue:tu];
    [userTwo setIntValue:nc];
    tu += nc;
    [totalUser setIntValue:tu];
    BOOL bust = [app checkBust:tu];
    if (bust == YES) {
        [console setIntValue:1];
        //Disable button here.
    }
}

我应该怎么办？

I made a button using Interface Builder and linked it to an action. I'd like to disable the hit button on the if statement below.

- (IBAction)hit:(id)sender {
    Application *app = [[Application alloc] init];
    int nc = [app dealCard];
    [userOne setIntValue:tu];
    [userTwo setIntValue:nc];
    tu += nc;
    [totalUser setIntValue:tu];
    BOOL bust = [app checkBust:tu];
    if (bust == YES) {
        [console setIntValue:1];
        //Disable button here.
    }
}

What should I do?

UIButton 是 UIResponder 的子类，它具有 enabled 属性。将其设置为 NO 以禁用按钮的操作。例如

UIButton *theButton = (UIButton *)sender;
theButton.enabled = NO;

UIButton is a subclass of UIResponder which has an enabled property. Set this to NO to disable the action from the button. E.g.

UIButton *theButton = (UIButton *)sender;
theButton.enabled = NO;

我发现了问题。事实证明，我使用的是 NSButton 而不是 UIButton，因此我将声明更改为：NSButton *theButton = (NSButton *)sender; 。

然后我将 theButton.enabled = NO; 替换为 [theButton setEnabled = NO];。

这是我完成的代码：

- (IBAction)hit:(id)sender {
    Application *app = [[Application alloc] init];
    NSButton *theButton = (NSButton *)sender;
    int nc = [app dealCard];
    [userOne setIntValue:tu];
    [userTwo setIntValue:nc];
    tu += nc;
    [totalUser setIntValue:tu];
    BOOL bust = [app checkBust:tu];
    if (bust == YES) {
        [console setIntValue:1];
        [theButton setEnabled = NO];
    }
}

I found the problem. It turns out I was using an NSButton instead of a UIButton so I changed the declaration to: NSButton *theButton = (NSButton *)sender;.

Then I replaced theButton.enabled = NO; to [theButton setEnabled = NO];.

So here's my finished code:

- (IBAction)hit:(id)sender {
    Application *app = [[Application alloc] init];
    NSButton *theButton = (NSButton *)sender;
    int nc = [app dealCard];
    [userOne setIntValue:tu];
    [userTwo setIntValue:nc];
    tu += nc;
    [totalUser setIntValue:tu];
    BOOL bust = [app checkBust:tu];
    if (bust == YES) {
        [console setIntValue:1];
        [theButton setEnabled = NO];
    }
}
