IOS 动画

2022-03-13 11:45:41

////////////////////////////////////////////////////////////////////////////////////////////

最普通动画:
//开始动画
[UIView beginAnimations:nil context:nil];
//设定动画持续时间
[UIView setAnimationDuration:2];
//动画的内容
frame.origin.x += 150;
[img setFrame:frame];
//动画结束
[UIView commitAnimations];

除了上述的实现方式 IOS4.0以后推荐用以下的函数进行实现

CGRect rect = [[UIScreen mainScreen] bounds];
self.view.center = CGPointMake(rect.size.width/2, 720);

[UIView animateWithDuration:0.5f animations:^{
self.view.center = CGPointMake(rect.size.width/2, 240+10);
} completion:^(BOOL finished) {
// [imageView setImageURL:[NSURL URLWithString:imgUrl]];
}];

//////////////////////////////////////////////////////////////////////////////////////////////////

//这个只能显示少数几张图片，如果图片多的话机会崩溃。

连续动画:一个接一个地显示一系列的图像
NSArray *myImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"myImage1.png"],
[UIImage imageNamed:@"myImage2.png"],
[UIImage imageNamed:@"myImage3.png"],
[UIImage imageNamed:@"myImage4.gif"], nil];

UIImageView *myAnimatedView = [UIImageView alloc];
[myAnimatedView initWithFrame:[self bounds]];
myAnimatedView.animationImages = myImages; //animationImages属性返回一个存放动画图片的数组
myAnimatedView.animationDuration = 0.25; //浏览整个图片一次所用的时间
myAnimatedView.animationRepeatCount = 0; // 0 = loops forever 动画重复次数
[myAnimatedView startAnimating];
[self addSubview:myAnimatedView];
[myAnimatedView release];

//////////////////////////////////////////////////////////////////////////////////////////////////

CATransition *animation=[CATransition animation];
animation.delegate=self;
animation.duration=1.0f;

animation.timingFunction=UIViewAnimationCurveEaseInOut;

animation.type=kCATransitionMoveIn;
animation.subtype=kCATransitionFromTop;
[myView.layer addAnimation:animation forKey:@"move in"];

setType：可以返回四种类型
kCATransitionFade淡出
kCATransitionMoveIn覆盖原图
kCATransitionPush推出
kCATransitionReveal底部显出来
setSubtype:也可以有四种类型：
kCATransitionFromRight；
kCATransitionFromLeft(默认值)
kCATransitionFromTop；
kCATransitionFromBottom

还有一种设置动画类型的方法，不用setSubtype，只用setType

animation.type=@"pageCurl";

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

*
* @see https://developer.apple.com/library/mac/#documentation/cocoa/conceptual/CoreAnimation_guide/Articles/KVCAdditions.html
*
* @brief 便利构造函数 animationWithKeyPath: KeyPath需要一个字符串类型的参数,实际上是一个
* 键-值编码协议的扩展,参数必须是CALayer的某一项属性,你的代码会对应的去改变该属性的效果
* 具体可以填写什么请参考上面的URL,切勿乱填!
* 例如这里填写的是 @"transform.rotation.z" 意思就是围绕z轴旋转,旋转的单位是弧度.
* 这个动画的效果是把view旋转到最小,再旋转回来.
* 你也可以填写@"opacity" 去修改透明度...以此类推.修改layer的属性,可以用这个类.
*
* @param toValue 动画结束的值.CABasicAnimation自己只有三个属性(都很重要)(其他属性是继承来的),分别为:
* fromValue(开始值), toValue(结束值), byValue(偏移值),
! 这三个属性最多只能同时设置两个;
* 他们之间的关系如下:
* 如果同时设置了fromValue和toValue,那么动画就会从fromValue过渡到toValue;
* 如果同时设置了fromValue和byValue,那么动画就会从fromValue过渡到fromValue + byValue;
* 如果同时设置了byValue 和toValue,那么动画就会从toValue - byValue过渡到toValue;
*
* 如果只设置了fromValue,那么动画就会从fromValue过渡到当前的value;
* 如果只设置了toValue ,那么动画就会从当前的value过渡到toValue;
* 如果只设置了byValue ,那么动画就会从从当前的value过渡到当前value + byValue.
*
* 可以这么理解,当你设置了三个中的一个或多个,系统就会根据以上规则使用插值算法计算出一个时间差并
* 同时开启一个Timer.Timer的间隔也就是这个时间差,通过这个Timer去不停地刷新keyPath的值.
! 而实际上,keyPath的值(layer的属性)在动画运行这一过程中,是没有任何变化的,它只是调用了GPU去
* 完成这些显示效果而已.
* 在这个动画里,是设置了要旋转到的弧度,根据以上规则,动画将会从它当前的弧度专旋转到我设置的弧度.
*
* @param duration 动画持续时间
*
* @param timingFunction 动画起点和终点之间的插值计算,也就是说它决定了动画运行的节奏,是快还是慢,还是先快后慢...

/** CAAnimationGroup
*
* @brief 顾名思义,这是一个动画组,它允许多个动画组合在一起并行显示.比如这里设置了两个动画,
* 把他们加在动画组里,一起显示.例如你有几个动画,在动画执行的过程中需要同时修改动画的某些属性,
* 这时候就可以使用CAAnimationGroup.
*
* @param duration 动画持续时间,值得一提的是,如果添加到group里的子动画不设置此属性,group里的duration会统一
* 设置动画(包括子动画)的duration属性;但是如果子动画设置了duration属性,那么group的duration属性
* 的值不应该小于每个子动画中duration属性的值,否则会造成子动画显示不全就停止了动画.
*
* @param autoreverses 动画完成后自动重新开始,默认为NO.
*
* @param repeatCount 动画重复次数,默认为0.
*
* @param animations 动画组(数组类型),把需要同时运行的动画加到这个数组里.
*
