価格ボタンを振る。それぞれの逆転の後、それは数秒待つべきです。
[UIView animateWithDuration:0.14f delay:0 options:(UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat | UIViewAnimationCurveEaseInOut) animations:^{
self.priceButton.transform = CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(3));
self.priceButton.transform = CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(-6));
self.priceButton.transform = CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(3));
} completion:nil];
どうやってやるの?
