iOS开发中常用的各种动画、页面切面效果
今天主要用到的动画类是calayer下的catransition至于各种动画类中如何继承的在这也不做赘述,网上的资料是一抓一大把。好废话少说切入今天的正题。
一.封装动画方法
1.用catransition实现动画的封装方法如下,每句代码是何意思,请看注释之。
#pragma catransition动画实现 - (void) transitionwithtype:(nsstring *) type withsubtype:(nsstring *) subtype forview : (uiview *) view { //创建catransition对象 catransition *animation = [catransition animation]; //设置运动时间 animation.duration = duration; //设置运动type animation.type = type; if (subtype != nil) { //设置子类 animation.subtype = subtype; } //设置运动速度 animation.timingfunction = uiviewanimationoptioncurveeaseinout; [view.layer addanimation:animation forkey:@"animation"]; }
代码说明:
catransition常用的属性如下:
duration:设置动画时间
type:稍后下面会详细的介绍运动类型
subtype:和type匹配使用,指定运动的方向,下面也会详细介绍
timingfunction :动画的运动轨迹,用于变化起点和终点之间的插值计算,形象点说它决定了动画运行的节奏,比如是
均匀变化(相同时间变化量相同)还是先快后慢,先慢后快还是先慢再快再慢.
* 动画的开始与结束的快慢,有五个预置分别为(下同):
* kcamediatimingfunctionlinear 线性,即匀速
* kcamediatimingfunctioneasein 先慢后快
* kcamediatimingfunctioneaseout 先快后慢
* kcamediatimingfunctioneaseineaseout 先慢后快再慢
* kcamediatimingfunctiondefault 实际效果是动画中间比较快.
2.用uiview的block回调实现动画的代码封装
#pragma uiview实现动画 - (void) animationwithview : (uiview *)view withanimationtransition : (uiviewanimationtransition) transition { [uiview animatewithduration:duration animations:^{ [uiview setanimationcurve:uiviewanimationcurveeaseinout]; [uiview setanimationtransition:transition forview:view cache:yes]; }]; }
3.改变view的背景图,便于切换时观察
#pragma 给view添加背景图 -(void)addbgimagewithimagename:(nsstring *) imagename { self.view.backgroundcolor = [uicolor colorwithpatternimage:[uiimage imagenamed:imagename]]; }
二.调用上面的方法实现我们想要的动画
1.我们在view上添加多个button,给不同的button设置不同的tag值,然后再viewcontroller中绑定同一个方法,点击不同的button实现不同的页面切换效果。storyboard上的控件效果如下图所示:
2.下面我们就开始编写点击button要回调的方法
(1).定义枚举来标示按钮所对应的动画类型,代码如下:
typedef enum : nsuinteger { fade = , //淡入淡出 push, //推挤 reveal, //揭开 movein, //覆盖 cube, //立方体 suckeffect, //吮吸 oglflip, //翻转 rippleeffect, //波纹 pagecurl, //翻页 pageuncurl, //反翻页 camerairishollowopen, //开镜头 camerairishollowclose, //关镜头 curldown, //下翻页 curlup, //上翻页 flipfromleft, //左翻转 flipfromright, //右翻转 } animationtype;
(2),获取button的tag值:
uibutton *button = sender; animationtype animationtype = button.tag;
(3).每次点击button都改变subtype的值,包括上,左,下,右
nsstring *subtypestring; switch (_subtype) { case : subtypestring = kcatransitionfromleft; break; case : subtypestring = kcatransitionfrombottom; break; case : subtypestring = kcatransitionfromright; break; case : subtypestring = kcatransitionfromtop; break; default: break; } _subtype += ; if (_subtype > ) { _subtype = ; }
(4),通过switch结合上边的枚举来判断是那个按钮点击的
switch (animationtype) { //各种case,此处代码下面会给出 }
3.调用我们封装的运动方法,来实现动画效果
(1),淡化效果
case fade: [self transitionwithtype:kcatransitionfade withsubtype:subtypestring forview:self.view]; break;
(2).push效果
case push: [self transitionwithtype:kcatransitionpush withsubtype:subtypestring forview:self.view]; break;
效果如下:
(3).揭开效果:
case reveal: [self transitionwithtype:kcatransitionreveal withsubtype:subtypestring forview:self.view]; break;
效果图如下:
(4).覆盖效果
case movein: [self transitionwithtype:kcatransitionmovein withsubtype:subtypestring forview:self.view]; break;
效果图如下:
(5).立方体效果
case cube: [self transitionwithtype:@"cube" withsubtype:subtypestring forview:self.view]; break;
效果如下:
(6).吮吸效果
case suckeffect: [self transitionwithtype:@"suckeffect" withsubtype:subtypestring forview:self.view]; break;
效果如下:
(7).翻转效果
case oglflip: [self transitionwithtype:@"oglflip" withsubtype:subtypestring forview:self.view]; break;
效果图如下:
8.波纹效果
case rippleeffect: [self transitionwithtype:@"rippleeffect" withsubtype:subtypestring forview:self.view]; break;
(9).翻页和反翻页效果
case pagecurl: [self transitionwithtype:@"pagecurl" withsubtype:subtypestring forview:self.view]; break; case pageuncurl: [self transitionwithtype:@"pageuncurl" withsubtype:subtypestring forview:self.view]; break;
(10).相机打开效果
case camerairishollowopen: [self transitionwithtype:@"camerairishollowopen" withsubtype:subtypestring forview:self.view]; break; case camerairishollowclose: [self transitionwithtype:@"camerairishollowclose" withsubtype:subtypestring forview:self.view]; break;
(11),调用上面封装的第二个动画方法
case curldown: [self animationwithview:self.view withanimationtransition:uiviewanimationtransitioncurldown]; break; case curlup: [self animationwithview:self.view withanimationtransition:uiviewanimationtransitioncurlup]; break; case flipfromleft: [self animationwithview:self.view withanimationtransition:uiviewanimationtransitionflipfromleft]; break; case flipfromright: [self animationwithview:self.view withanimationtransition:uiviewanimationtransitionflipfromright]; break;
