[英]UIView animation not working - Xcode (Swift)
示例:我沒有看到任何 animation。 為什么?
UIView.animate(withDuration: 1, delay: 0, options: [.repeat, .autoreverse], animations: {
self.buttonTrial.transform = CGAffineTransform(scaleX: 1.2, y: 1.2)
}, completion: { completion in
self.buttonTrial.transform = .identity
})
