I have button that show up a modal view but i want that if the user click it he wont be able to use it again for 90 seconds. how can i do this?

推荐答案

在按钮的IBAction为禁用按钮，设置这样的计时器：

In the IBAction of the button disable the button and set a timer like this:

self.button.enabled = false
NSTimer.scheduledTimerWithTimeInterval(90, target: self, selector: "enableButton", userInfo: nil, repeats: false)

和创建称为FUNC当定时器计数结束：

And create the func called when the timer ends counting:

func enableButton() {
    self.button.enabled = true
}
