如何在Swift iOS8中使用代码模拟按钮

如何使用 Swift在视图内模拟按钮.我正在尝试获取日历权限,并有一个功能设置来检查此授权,当我单击当前运行的开始按钮

@IBAction func start(sender: AnyObject) {
//loads prompt to "Allow" or "Don't Allow" calendar permissions
eventStore.requestAccesstoEntityType(EKEntityTypeEvent,completion: handler)

//checkAuth function looks at calendar authorization to get current status 
and then acts accordingly to dismiss View or load Privacy Settings
checkAuth()

}

我需要能够模拟按下“开始”按钮的按钮,再次触发start()func.到目前为止,我发现的唯一的事情似乎在Objective-C

[buttonObj sendActionsForControlEvents：UIControlEventTouchUpInside];

我不熟悉Obj-C,如果可能,需要一种在Swift中实现的方法…谢谢

Swift翻译：

[buttonObj sendActionsForControlEvents: UIControlEventTouchUpInside];

是：

buttonObj.sendActionsForControlEvents(UIControlEvents.TouchUpInside)

实际上它应该是模拟按钮推送.
