Animation--1
1.头尾式动画
开启动画
[UIView beginAnimations:nil context:nil];
设置动画执行时间
[UIView setAnimationDuration:0.5];
---动画的内容---
提交动画
[UIView commitAnimations];
2.block式动画
[UIView animateWithDuration:0.5 animations:^{
---动画的内容---
}];
每一种都有一次和多次两种
平移
[UIView animateWithDuration:0.5 animations:^{
self.PinkView.frame = CGRectMake(_PinkView.frame.origin.x, _PinkView.frame.origin.y + 100,_PinkView.frame.size.width,_PinkView.frame.size.height);
}];改变了图片的位置
[UIView animateWithDuration:0.5 animations:^{
_PinkView.transform = CGAffineTransformTranslate(_PinkView.transform, 10, 10);
}]; 没有改变图片的位置
渐变
[UIView animateWithDuration:0.5 animations:^{
self.PinkView.alpha = !self.PinkView.alpha;
}];
翻页效果
[UIView beginAnimations:nil context:nil];//开始动画的配置
[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:_PinkView cache:NO];
[UIView commitAnimations];//动画配置完毕,提交动画
旋转,只能做一次
[UIView animateWithDuration:0.5 animations:^{
_PinkView.transform = CGAffineTransformMakeRotation(M_PI);
}];
多次
[UIView animateWithDuration:0.5 animations:^{
_PinkView.transform = CGAffineTransformRotate(_PinkView.transform, M_PI_4);
}];
放大缩小
[UIView animateWithDuration:0.1 animations:^{
_PinkView.transform = CGAffineTransformMakeScale(2, 2);
}];
[UIView animateWithDuration:0.5 animations:^{
_PinkView.transform = CGAffineTransformMakeScale(0.5, 0.5);
}];
还原
_PinkView.transform = CGAffineTransformIdentity;
