Swift gets and changes the caption text of the button (UIButton click to toggle title)

In development, we often need to dynamically change the button label text, using the Settitle () function on it. Sometimes we need to switch between several headings, as shown in the example below, and the button text will switch between "play" and "pause" after the button is clicked.

To do this, first get the button's current caption text, like the next two ways:

1, using Currenttitle to get

if Mybtn.currenttitle = = "Play" {
Mybtn.settitle ("Paused", forstate:.) Normal)
} else {
Mybtn.settitle ("Play", Forstate:.) Normal)
}

2, use Titleforstate () to get

If Mybtn.titleforstate (. Normal) = = "Play" {
Mybtn.settitle ("Paused", forstate:.) Normal)
} else {
Mybtn.settitle ("Play", Forstate:.) Normal)
}
