动画
1.UIVIew
1.1 动画块(改变背景颜色和移动)
static BOOL flag=YES;
//开始动画
[UIView beginAnimations:nil context:nil];
//运动的时间
[UIView setAnimationDuration:2.f];
//延时启动
[UIView setAnimationDelay:2.f];
//速度曲线
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
//代理
[UIView setAnimationDelegate:self];
//开始时候执行
[UIView setAnimationWillStartSelector:@selector(startAction)];
//结束时候执行
// [UIView setAnimationDidStopSelector:@selector(stopAction)];
//重复执行
[UIView setAnimationRepeatAutoreverses:YES];
//重复执行次数
[UIView setAnimationRepeatCount:5];
//动画过程(换背景色)
self.myView.backgroundColor=[UIColor colorWithRed:arc4random()%256/255.0 green:arc4random()%256/255.0 blue:arc4random()%256/255.0 alpha:1];
//改位置
CGRect myFrame=self.myView.frame;
if (flag) {
//向下移动
myFrame.origin.y+=100;
myFrame.size.height+=150;
flag=NO;
}
else
{
myFrame.origin.y-=100;
myFrame.size.height-=150;
flag=YES;
}
self.myView.frame=myFrame;
self.myView.alpha=0.5;
//提交动画
[UIView commitAnimations];
************
1.2 block块
//自己的Block块
[self myAnimationDuration:2.f animaton:^{
self.myView.backgroundColor=[UIColor grayColor];
}];
//系统提供的Block
[UIView animateWithDuration:2.f animations:^{
self.myView.backgroundColor=[UIColor greenColor];
}];
//第一个Block块执行动画
//第二个Block块是在执行完动画后执行
[UIView animateWithDuration:2.f animations:^{
self.myView.backgroundColor=[UIColor greenColor];
} completion:^(BOOL finished) {
self.myView.backgroundColor=[UIColor redColor];
}];
//自己定义的动画Block块方法
-(void)myAnimationDuration:(NSTimeInterval )time animaton:(animation)ani
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:time];
ani();
[UIView commitAnimations];
}
***********
1.3UIViewYransition
//第一个方法
[UIView transitionWithView:self.myView duration:2.f options:(UIViewAnimationOptionTransitionFlipFromBottom) animations:^{
NSLog(@"动画开始了");
} completion:^(BOOL finished) {
NSLog(@"动画结束了");
}];
//第二个方法
[UIView transitionWithView:<#(UIView *)#> duration:<#(NSTimeInterval)#> options:<#(UIViewAnimationOptions)#> animations:<#^(void)animations#> completion:<#^(BOOL finished)completion#>]
2.CGAffineTransfrom
[UIView animateWithDuration:2.f animations:^{
//缩小(基于前一次变化)
self.myView.transform=CGAffineTransformScale(self.myView.transform, 0.2f, 0.2f);
//旋转(基于前一次变化)
self.myView.transform=CGAffineTransformRotate(self.myView.transform, M_PI);
}];
3.CALayer 的属性
//设置圆角
self.myView.layer.cornerRadius=50;
//边框颜色
self.myView.layer.borderWidth=20;
self.myView.layer.borderColor=[UIColor redColor].CGColor;
//阴影颜色
self.myView.layer.shadowColor=[UIColor grayColor].CGColor;
//阴影偏移
self.myView.layer.shadowOffset=CGSizeMake(-10, 10);
//透明度必须设置
self.myView.layer.shadowOpacity=0.3;
//模糊程度
self.myView.layer.shadowRadius=4;
//设置锚点
self.myView.layer.anchorPoint=CGPointMake(.5, .5);

4.CAPropertyAnimation(两个子类CABasicAnimation和CAKeyframeAnimation)
4.1.CABasicAnimation
//CALayer
//UIView的属性动画,会修改属性产生动画.
//CALayer,没有修改UIView属性
//创建animation对象
CABasicAnimation *animation=[CABasicAnimation animationWithKeyPath:@"position"];
//从那儿开始
animation.fromValue=[NSValue valueWithCGPoint:self.myView.layer.position];
//到哪儿结束
animation.toValue=[NSValue valueWithCGPoint:CGPointMake(200, 200)];
//设置时间
animation.duration=2.0;
//自动执行
animation.autoreverses=YES;
//执行次数
animation.repeatCount=3;
//添加到self.view.layer 上
[self.myView.layer addAnimation:animation forKey:@"position动画"];
//缩放动画
CABasicAnimation *animation=[CABasicAnimation animationWithKeyPath:@"transform.scale"];
//初始值
animation.fromValue=[NSNumber numberWithFloat:1.0];
//结束值
animation.toValue=[NSNumber numberWithFloat:3.0];
//设置时间
animation.duration=0.1;
////自动执行
animation.autoreverses=YES;
//执行次数
animation.repeatCount=100;
//添加到self.view.layer 上
[self.myView.layer addAnimation:animation forKey:@"缩放动画"];
4.2CAKeyframeAnimation
//指定位置移动
CAKeyframeAnimation *animation=[CAKeyframeAnimation animationWithKeyPath:@"position"];
//持续时间
animation.duration=2.0;
//自动
animation.autoreverses=YES;
//此数
animation.repeatCount=30;
NSArray *array=@[[NSValue valueWithCGPoint:CGPointMake(50, 50)],[NSValue valueWithCGPoint:CGPointMake(200, 25)],[NSValue valueWithCGPoint:CGPointMake(25, 200)],[NSValue valueWithCGPoint:CGPointMake(200, 200)]];
animation.values=array;
//添加到self.view.layer 上
[self.myView.layer addAnimation:animation forKey:@"动画"];
*****************************************
5.CAAnimationGroup
CAAnimationGroup *group=[CAAnimationGroup animation];
//第一个动画
CABasicAnimation *animation=[CABasicAnimation animationWithKeyPath:@"transform.scale"];
animation.fromValue=[NSNumber numberWithFloat:1.0];
animation.toValue=[NSNumber numberWithFloat:3.0];
//第二个动画
CAKeyframeAnimation *animation1=[CAKeyframeAnimation animationWithKeyPath:@"position"];
NSArray *arr=@[[NSValue valueWithCGPoint:CGPointMake(50, 50)],[NSValue valueWithCGPoint:CGPointMake(200, 50)],[NSValue valueWithCGPoint:CGPointMake(50, 200)],[NSValue valueWithCGPoint:CGPointMake(200, 200)]];
animation1.values=arr;
//添加到动画数组
group.animations=@[animation,animation1];
group.duration=1;
group.autoreverses=YES;
group.repeatCount=500;
//数组添加到view的layer上
[self.myView.layer addAnimation:group forKey:@"组合"];
6.CATransition
/*
pageCurl 向上翻一页
pageUnCurl 向下翻一页
rippleEffect 滴水效果
suckEffect 收缩效果，如一块布被抽走
cube 立方体效果
oglFlip 上下翻转效果
*/
CATransition *ani=[CATransition animation];
ani.type=@"cube";
ani.subtype=kCATransitionFromLeft;
ani.duration=2;
ani.repeatCount=30;
[self.myView.layer addAnimation:ani forKey:@"动画"];
UIAnimation包括三个子类:(CAnimationGroup. CAPropertyAnimation(两个子类CABasicAnimation,CAkeyFraneAnimation).CATransition)
