這里不僅有present和dismiss在viewController中跳轉(zhuǎn)捶码，還有各種動(dòng)畫push和pop，當(dāng)然view的動(dòng)畫出場也是必不可少的或链。拿了直接用即可惫恼，簡單粗暴看代碼，這里可以讓你知其然澳盐，知其所以然祈纯。
PresentAnimation
實(shí)現(xiàn)UIViewControllerTransitioningDelegate的代理方法，把present從下面出來的view從右邊動(dòng)畫出來叼耙，具體代碼看github代碼腕窥，具體方法如下：
-(NSTimeInterval)transitionDuration:(id<UIViewControllerContextTransitioning>)transitionContext{
return 1.0;
}
-(void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext{
UIViewController * fromViewController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
UIViewController * toViewController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
UIView *containerView = [transitionContext containerView];
UIView *fromView = nil;
UIView *toView = nil;
if ([transitionContext respondsToSelector:@selector(viewForKey:)]) {
fromView = [transitionContext viewForKey:UITransitionContextFromViewKey];
toView = [transitionContext viewForKey:UITransitionContextToViewKey];
}else{
fromView = fromViewController.view;
toView = toViewController.view;
}
BOOL isPresent = (toViewController.presentingViewController == fromViewController);
CGRect fromFrame = [transitionContext initialFrameForViewController:fromViewController];
CGRect toFrame = [transitionContext finalFrameForViewController:toViewController];
if (isPresent) {
fromView.frame = fromFrame;
toView.frame = CGRectOffset(toFrame, toFrame.size.width, 0);
[containerView addSubview:toView];
}
NSTimeInterval transitionDuration = [self transitionDuration:transitionContext];
[UIView animateWithDuration:transitionDuration animations:^{
if (isPresent) {
toView.frame = toFrame;
fromView.frame = CGRectOffset(fromFrame, fromFrame.size.width*0.3*-1, 0);
}
} completion:^(BOOL finished) {
BOOL isCancelled = [transitionContext transitionWasCancelled];
if (isCancelled)
[toView removeFromSuperview];
[transitionContext completeTransition:!isCancelled];
}];
}
(id<UIViewControllerAnimatedTransitioning>)animationControllerForPresentedController:(UIViewController *)presented presentingController:(UIViewController *)presenting sourceController:(UIViewController *)source{
return (id)[[PresentAnimation alloc]init];
}
DismissAnimation
- (NSTimeInterval)transitionDuration:(id<UIViewControllerContextTransitioning>)transitionContext{
return 1.0;
}
-(void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext{
UIViewController *fromViewController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
UIViewController *toViewController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
UIView *containerView = [transitionContext containerView];
UIView *fromView = nil;
UIView *toView = nil;
if ([transitionContext respondsToSelector:@selector(viewForKey:)]) {
fromView = [transitionContext viewForKey:UITransitionContextFromViewKey];
toView = [transitionContext viewForKey:UITransitionContextToViewKey];
}else{
fromView = fromViewController.view;
toView = toViewController.view;
}
BOOL isDismiss = (fromViewController.presentingViewController == toViewController);
CGRect fromFrame = [transitionContext initialFrameForViewController:fromViewController];
CGRect toFrame = [transitionContext finalFrameForViewController:toViewController];
if (isDismiss) {
fromView.frame = fromFrame;
toView.frame = CGRectOffset(toFrame, toFrame.size.width*0.3*-1, 0);
[containerView insertSubview:toView belowSubview:fromView];
}
NSTimeInterval transitionDuration = [self transitionDuration:transitionContext];
[UIView animateWithDuration:transitionDuration animations:^{
if (isDismiss) {
toView.frame = toFrame;
fromView.frame = CGRectOffset(fromFrame, fromFrame.size.width, 0);
}
} completion:^(BOOL finished) {
BOOL isCancel = [transitionContext transitionWasCancelled];
if (isCancel) {
[toView removeFromSuperview];
}
[transitionContext completeTransition:!isCancel];
}];
}
- (nullable id <UIViewControllerAnimatedTransitioning>)animationControllerForDismissedController:(UIViewController *)dismissed {
return (id)[[DismissAnimation alloc]init];
}
PushAnimation
動(dòng)畫添加新的view，type和subType不同筛婉，動(dòng)畫方式就不一樣簇爆。這里只寫一個(gè)不累贅
+(void)pushView:(UIView *)View subView:(UIView *)subView AndAnimationType:(NSString *)type AndsubType:(NSString *)subType{
CATransition *transition = [CATransition animation];
transition.duration = 1.0f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = type;
transition.subtype = subType;
[View.layer addAnimation:transition forKey:@"pushTransitionAnimation"];
[View addSubview:subView];
}
PopAnimation
動(dòng)畫移除新的view
+(void)popView:(UIView *)View subView:(UIView *)subView AndAnimationType:(NSString *)type AndsubType:(NSString *)subType {
CATransition *transition = [CATransition animation];
transition.duration = 1.0f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = type;
transition.subtype = subType;
[View.superview.layer addAnimation:transition forKey:@"popTransitionAnimation"];
[subView removeFromSuperview];
}
注：關(guān)于CATransition的type和subType的介紹，前兩篇博客已經(jīng)介紹過，看Animation_CATransition這篇入蛆。
ScaleViewAnimation
CGAffineTransform 主要用于形變响蓉，位移和旋轉(zhuǎn)，可用于動(dòng)畫展示
transform屬性介紹哨毁，這里介紹最常用和好用的枫甲，其他屬性去看CGAffineTransform
-
位移X,Y
CGAffineTransformMakeTranslation(CGFloat tx, CGFloat ty) -
伸縮X,Y
CGAffineTransformMakeScale(CGFloat sx, CGFloat sy) -
旋轉(zhuǎn)M_PI
CGAffineTransformMakeRotation(CGFloat angle) -
組合
CGAffineTransformConcat(CGAffineTransform t1,CGAffineTransform t2) -
回到原位
CGAffineTransformIdentity
動(dòng)畫調(diào)用，包括動(dòng)畫時(shí)間扼褪，動(dòng)畫完成后回調(diào)
-(void)scaleView:(UIView *)view CGFloatX:(CGFloat)x CGFloatY:(CGFloat)y CGFloatW:(CGFloat)w CGFloatH:(CGFloat)h{
CGFloat scaleW = self.window.frame.size.width / w;
CGFloat scaleH = self.window.frame.size.height / h;
CGFloat W = scaleW * 50 - 50 - x;
CGFloat H = scaleH * 50 - 50 - y;
[UIView animateWithDuration:1.0 animations:^{
view.transform =CGAffineTransformConcat(CGAffineTransformMakeScale(scaleW, scaleH), CGAffineTransformMakeTranslation(W,H));
} completion:^(BOOL finished) {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
view.transform = CGAffineTransformIdentity;
});
}];
}
