IOS：具有两个操作的 IBAction

发布于 2024-12-10 16:18:29 字数 375 浏览 0 评论 0原文

在我的应用程序中，我有一个 ibaction，其中有 2 条不同的指令，其中有一个“if”，

 if (i == 0)  //do instruction set 1
 if (i == 1) //do instruction set 2
 // and everytime I push button i change from 0 to 1 or from 1 to 0

问题是，如果我重复按下此 IbAction 的按钮，它就无法正常工作，因为前一个 ibaction 未完成其指令集1

示例=按下按钮，它执行指令集1，如果我再次按下该按钮，它不应该工作，因为它没有完成其工作，并且我想等待指令集1结束以重复按下按钮。

你明白吗？

In my app I have an ibaction and inside it I have 2 different instruction with an "if"

 if (i == 0)  //do instruction set 1
 if (i == 1) //do instruction set 2
 // and everytime I push button i change from 0 to 1 or from 1 to 0

the problem is that if I repeatedly press the button of this IbAction it don't work fine because the previous ibaction didn't finish its instruction set1

example = press button, it execute instruction set 1, if I push another time the button it shouldn't work because it it didn't finish its work and I want to wait the end of instruction set 1 to repeat the push of button.

Do you understand?

假设您的类中有 BOOL workInProgress 变量：

- (IBAction)action {
    if (!workInProgress) {
        workInProgress = YES;
        if (i == 0) {
            // do something that in the end sets workInProgress to NO
        } else if (i == 1) {
            // do something else that in the end sets workInProgress to NO
        }
    }
}

Assuming you have BOOL workInProgress variable in your class:

- (IBAction)action {
    if (!workInProgress) {
        workInProgress = YES;
        if (i == 0) {
            // do something that in the end sets workInProgress to NO
        } else if (i == 1) {
            // do something else that in the end sets workInProgress to NO
        }
    }
}
