视图切换的动画效果

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。
