iPhone动画表现效果

 

 

iPhone开发中,我们常常需要在不同的页面之间做动画的切换,这样看起来更加好看。基本的动画有以下三种:

1.UIView

UIView官方提供五种动画效果供大家使用,分别为:

UIViewAnimationTransitionNone    不使用动画UIViewAnimationTransitionFlipFromLeft    从左向右旋转翻页UIViewAnimationTransitionFlipFromRight    从右向左旋转翻页,与UIViewAnimationTransitionFlipFromLeft相反UIViewAnimationTransitionCurlUp    卷曲翻页,从下往上UIViewAnimationTransitionCurlDown    卷曲翻页,从上往下

 

例子:

[UIView beginAnimations:@"animationID" context:nil];//开始一个动画块,第一个参数为动画块标识[UIView setAnimationDuration:0.5f];//设置动画的持续时间[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];//设置动画块中的动画属性变化的曲线,此方法必须在beginAnimations方法和commitAnimations,默认即为UIViewAnimationCurveEaseInOut效果。详细请参见UIViewAnimationCurve[UIView setAnimationRepeatAutoreverses:NO];//设置是否自动反转当前的动画效果[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES];//设置过渡的动画效果,此处第一个参数可使用上面5种动画效果[self.view exchangeSubviewAtIndex:1 withSubviewAtIndex:0];//页面翻转[UIView commitAnimations];//提交动画

 

这样,我们就可以让UIView的页面通过动画实现页面之间的跳转。

2. CATransiton

CATransiton官方提供4种动画效果,分别为:

NSString * const kCATransitionFade;//渐渐消失

NSString * const kCATransitionMoveIn;//覆盖进入

NSString * const kCATransitionPush;//推出

NSString * const kCATransitionReveal;//MoveIn相反

 

例子:

CATransition *animation = [CATransition animation];//初始化动画animation.duration = 0.5f;//间隔的时间animation.timingFunction = UIViewAnimationCurveEaseInOut;animation.type = kCATransitionPush;//设置上面4种动画效果animation.subtype = kCATransitionFromTop;//设置动画的方向,有四种,分别为kCATransitionFromRightkCATransitionFromLeftkCATransitionFromTopkCATransitionFromBottom[self.view.layer addAnimation:animation forKey:@"animationID"];

 


 

3.私有动画

私有动画是在UIView的基础上,设置animation.type,可以提供一下几种选择:

cube:像立方体那样翻转

suckEffect:渐渐缩小,与删除照片的动画一样

oglFlip:上下旋转,当subTypefromLeft或者fromRight时,与UIViewAnimationTransitionFlipFromLeftUIViewAnimationTransitionFlipFromRight一样

rippleEffect:水波效果

pageCurl:与UIViewAnimationTransitionCurlUp一样

pageUnCurl:与UIViewAnimationTransitionCurlDown一样

cameraIrisHollowOpenFirst half of cameraIris.

cameraIrisHollowCloseSecond half of cameraIris

附加一个动画的源代码给大家参考一下,今天将的动画效果就到此介绍。谢谢大家。

应用开发中总要用到加载数据时候的loading动画效果 以下为一个loading效果实例,可以直接拿去用的:

在你的xxxController 头文件中声明: UIView *colorView;

UIActivityIndicatorView *aciv;

初始化中定义: aciv = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray]; colorView=[[UIView alloc]initWithFrame:CGRectMake(0, 0, screenWidth, screenHeight)];

[colorView setBackgroundColor:[UIColor colorWithRed:0.2 green:0.2 blue:0.2 alpha:0.4]];

加入以下方法:

- (void)addLoading{

aciv.activityIndicatorViewStyle=UIActivityIndicatorViewStyleWhite;

aciv.center=CGPointMake(screenWidth/2,screenHeight/2-10);

[self.view addSubview:colorView];

[aciv startAnimating];

[self.view addSubview:aciv];

}

- (void)removeLoading{

[colorView removeFromSuperview];

[aciv stopAnimating];

[aciv removeFromSuperview];

}

注释掉 //[self.view addSubview:colorView];

//[colorView removeFromSuperview];

则动画没有灰色背景 界面切换则可以有很多效果,如淡入淡出,放大,雾化,翻转等。 淡入淡出:

- (void)animateEaseInEaseOut:(CALayer*)laye delegate:(id)del{

CATransition *animationA = [CATransition animation];

[animationA setType:kCATransitionFade];

[animationA setDuration:1];

[animationA setDelegate:del];

[animationA setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; [laye addAnimation:animationA forKey:@"EaseInEaseOut"];

}

翻转:

- (void)animateFlipView{

[UIView beginAnimations:nil context:NULL];

[UIView setAnimationDuration:1];

[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES];

[UIView commitAnimations];

}
