Learn how to add a button to the app and connect it to some Swift 4 code that prints a message to the console.
In this section, when connecting the Hit Me! button to the showAlert() function, you said to drag the Hit Me! up to the View Controller. When I do this, nothing happens. Help??
If nothing shows up when you drag from a button up to the view controller, that usually means Xcode can’t find any methods in the view controller marked with @IBAction
.
The way to fix it is to double check that an action method exists in your view controller, like the video shows how to make at 4:30. If that still doesn’t work, try comparing your project to the solution. I hope that helps!
i think you need to press control then drag the hit me to view controller.
This is probably a rookie question. After you create the “Hit Me” button in the view controller, in the video ray says run and it pops up on the iPhone to the right. I am confused right here, what exactly do I do to complete this task of having the “Hit Me” button pop up on the iPhone. I’ve watched the video over and over.
Thanks in advance.
