主流转场动画
1、API只有两个方法，易调用
2、面向切面编程，无侵入，不需要在VC中设置代理
3、易扩展，只需要重写转场对象即可
1、不够灵活，对于同一个转场对象无法设置不同的转场时间
2、如果需要传参，需要通过协议传递，漏写协议，编译时无法发现问题
//present转场
- (void)hh_presentViewController:(UIViewController *)viewController presentStyle:(HHPresentStyle)presentStyle completion:(void (^__nullable)(void))completion
//push转场
- (void)hh_pushViewController:(UIViewController *)viewController style:(HHPushStyle)style;例如：
[testViewController hh_presentViewController:viewController presentStyle:HHPresentStyleSlipFromTop completion:nil];1、在HHTransitionUtility类下，增加枚举类型
2、增加转场对象，可以继承HHBaseAnimatedTransition，内部已做好分发
3、在类HHInteractionDelegate或者HHTransitioningDelegate下，根据枚举类型，设置transition对象
例如：
- (id<UIViewControllerAnimatedTransitioning>)animationControllerForPresentedController:(UIViewController *)presented presentingController:(UIViewController *)presenting sourceController:(UIViewController *)source {
switch (presented.presentStyle) {
case HHPresentStyleNone:
return nil;
case HHPresentStyleSlipFromTop:
case HHPresentStyleSlipFromBottom:
case HHPresentStyleSlipFromLeft:
case HHPresentStyleSlipFromRight:
return [HHPresentFlipTransition flipTransitionWithStyle:presented.presentStyle isBegining:YES];
default:
return nil;
}
}- (id<UIViewControllerAnimatedTransitioning>)animationControllerForDismissedController:(UIViewController *)dismissed {
switch (dismissed.presentStyle) {
case HHPresentStyleNone:
return nil;
case HHPresentStyleSlipFromTop:
case HHPresentStyleSlipFromBottom:
case HHPresentStyleSlipFromLeft:
case HHPresentStyleSlipFromRight:
return [HHPresentFlipTransition flipTransitionWithStyle:dismissed.presentStyle isBegining:NO];
default:
return nil;
}
}部分效果如下
2018-05-17增加CATransition动画
支持cocoapod
target 'MyApp' do
pod 'HHTransition', '~> 3.1.2'
end
