转载 动画选择问题 CATransition
要给webView加动画,看了下动画的添加,发现要使用 [UIView beginAnimations:@"animationID" context:nil]; 这种的话就是整个页面全是动画翻转,这不是我所想看到的。所以最后选择了CATrasition,图层的方式,感觉还是比较好用的。下面是动画的简单比较~~ 懒得写了 直接转载

为了避免视图之间切换的呆板问题,在IPHONE中引入了转换动画效果,分别在UIKit.framework和QuartzCore.framework中,后者的动画类型要比前者丰富一些。
- - (IBAction)switchViews:(id)sender{
- //准备动画
- [UIView beginAnimations:@"animationID" context:nil];
- //动画播放持续时间
- [UIView setAnimationDuration:0.5f];
- //动画速度
- [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
- [UIView setAnimationRepeatAutoreverses:NO];
- UIButton *theButton = (UIButton *)sender;
- //动画方向
- switch (theButton.tag) {
- case 0:
- [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES];
- break;
- case 1:
- [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES];
- break;
- case 2:
- [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
- break;
- case 3:
- [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
- break;
- default:
- break;
- }
- [self.view exchangeSubviewAtIndex:1 withSubviewAtIndex:0];
- [UIView commitAnimations];
- }
下面的动画需要导入QuartzCore.framework库,并在实现文件中导入。
- #import <QuartzCore/QuartzCore.h>
- - (IBAction)switchViews:(id)sender{
- //准备动画
- CATransition *animation = [CATransition animation];
- animation.delegate = self;
- //动画播放持续时间
- animation.duration = 0.5f;
- //动画速度
- animation.timingFunction = UIViewAnimationCurveEaseInOut;
- animation.fillMode = kCAFillModeForwards;
- animation.removedOnCompletion = NO;
- UIButton *theButton = (UIButton *)sender;
- //动画效果
- switch (theButton.tag) {
- case 0:
- animation.type = @"cube";
- break;
- case 1:
- animation.type = @"suckEffect";
- break;
- case 2:
- animation.type = @"oglFlip";
- break;
- case 3:
- animation.type = @"rippleEffect";
- break;
- case 4:
- animation.type = @"pageCurl";
- break;
- case 5:
- animation.type = @"pageUnCurl";
- break;
- case 6:
- animation.type = @"cameraIrisHollowOpen ";
- break;
- case 7:
- animation.type = @"cameraIrisHollowClose ";
- break;
- default:
- break;
- }
- [self.view.layer addAnimation:animation forKey:@"animation"];
- [self.view exchangeSubviewAtIndex:1 withSubviewAtIndex:0];
- }
下面的动画同样需要导入QuartzCore.framework库,并在实现文件中导入。
- #import <QuartzCore/QuartzCore.h>
- - (IBAction)switchViews:(id)sender{
- CATransition *animation = [CATransition animation];
- animation.duration = 0.5f;
- animation.timingFunction = UIViewAnimationCurveEaseInOut;
- animation.fillMode = kCAFillModeForwards;
- UIButton *theButton = (UIButton *)sender;
- switch (theButton.tag) {
- case 0:
- /*动画效果
- kCATransitionFade
- kCATransitionMoveIn
- kCATransitionPush
- kCATransitionReveal
- */
- animation.type = kCATransitionPush;
- /*动画方向
- kCATransitionFromRight
- kCATransitionFromLeft
- kCATransitionFromTop
- kCATransitionFromBottom
- */
- animation.subtype = kCATransitionFromTop;
- break;
- case 1:
- animation.type = kCATransitionMoveIn;
- animation.subtype = kCATransitionFromTop;
- break;
- case 2:
- animation.type = kCATransitionReveal;
- animation.subtype = kCATransitionFromTop;
- break;
- case 3:
- animation.type = kCATransitionFade;
- animation.subtype = kCATransitionFromTop;
- break;
- default:
- break;
- }
- [self.view.layer addAnimation:animation forKey:@"animation"];
- }
UIKit.framework中的动画是对UIView的,而QuartzCore.framework是针对视图的属性layer来实现的,后者与视图动画比起来,具备更大的优势,更容易进行转换,倾斜,放大,缩小等等。
