Objective c 单击按钮10秒后运行iAction

我有一个

iAction

链接到一个按钮。单击按钮时，将播放.wav文件。 单击按钮10秒后，如何使

iAction

运行？

您可以使用

---

将其放入按下按钮时调用的iAction调用中，10秒后将调用

myFunc

。

您可以使用

dispatch\u after

延迟代码执行：

- (IBAction) onAction: (id)sender
{
    double delayInSeconds = 10.0;
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){

        // do delayed work here
    });
}

- (IBAction) onAction: (id)sender
{
    double delayInSeconds = 10.0;
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){

        // do delayed work here
    });
}
