How to click a button programmatically?
提问by Coding4Life
I have 2 view controllers which should be swapped according to userinput. So, I want to switch the views programatically based on the input I get from a text file.
我有 2 个视图控制器，它们应该根据用户输入进行交换。所以，我想根据我从文本文件中获得的输入以编程方式切换视图。
Algorithm :
if(input == 1)
{
Go to View Controller 1
}
else if(input ==2)
{
Go to View Controller 2
}
Any help on how to click the button programmatically or load that particular viewcontroller with input?

To fire an event programmatically you need to call sendActionsForControlEvent
要以编程方式触发事件，您需要调用 sendActionsForControlEvent
button.sendActionsForControlEvents(.TouchUpInside)

button.sendActions(for: .touchUpInside)

Or you can just put all the logic that you perform when a button gets clicked in a separate method, and call that method from your button's selector method.
或者，您可以将单击按钮时执行的所有逻辑放在单独的方法中，然后从按钮的选择器方法中调用该方法。
@IBAction func someButtonPressed(button: UIButton) {
pushViewControllerOne()
}
@IBAction func someButtonPressed(button: UIButton) {
pushViewControllerTwo()
}
func pushViewControllerOne() {
let viewController = ViewControllerOne(nibName: "ViewControllerOne", bundle: nil)
pushViewController(viewController)
}
func pushViewControllerTwo() {
let viewController = ViewControllerOne(nibName: "ViewControllerTwo", bundle: nil)
pushViewController(viewController)
}
func pushViewController(viewController: UIViewController) {
navigationController?.pushViewController(viewController, animated: true)
}
Then instead of invoking programatically invoking a button press, just call the method pushViewControllerOne()or pushViewControllerTwo()
然后不是以编程方式调用按钮按下，只需调用方法pushViewControllerOne()或pushViewControllerTwo()
