Objective-C 的

CATransition* transition = [CATransition animation];
transition.startProgress = 0;
transition.endProgress = 1.0;
transition.type = @"flip";
transition.subtype = @"fromLeft";
transition.duration = 0.8;
transition.repeatCount = 5;
[_label.layer addAnimation:transition forKey:@"transition"];

迅速

var transition = CATransition()
transition.startProgress = 0
transition.endProgress = 1.0
transition.type = "flip"
transition.subtype = "fromLeft"
transition.duration = 0.8
transition.repeatCount = 5
label.layer.addAnimation(transition, forKey: "transition")
