一般我们就用两种转场push和present
present
/** 1.设置代理 - (instancetype)init { self = [super init]; if (self) { self.transitioningDelegate = self; self.modalPresentationStyle = UIModalPresentationCustom; } return self; } 2.添加协议<UIViewControllerTransitioningDelegate> 3.重写协议方法 － 在协议方法里面初始化 - (id<UIViewControllerAnimatedTransitioning>)animationControllerForPresentedController:(UIViewController *)presented presentingController:(UIViewController *)presenting sourceController:(UIViewController *)source{ } - (id<UIViewControllerAnimatedTransitioning>)animationControllerForDismissedController:(UIViewController *)dismissed{ } **/
2.push
第一个控制器推第二个控制器的时候
ViewController2 *vc = [[ViewController2 alloc]init]; self.navigationController.delegate = vc; //必须写这句话 [self.navigationController pushViewController:vc animated:YES];
第二个控制器
@interface ViewController2 : UIViewController<UINavigationControllerDelegate> @end
代理方法
- (id<UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController animationControllerForOperation:(UINavigationControllerOperation)operation fromViewController:(UIViewController *)fromVC toViewController:(UIViewController *)toVC { }
上面就是push和present发生的地方，都需要返回一个 UIViewControllerAnimatedTransitioning
所以我们写一个类
@interface WJTransiation_Mobile : NSObject<UIViewControllerAnimatedTransitioning>
@end
然后修改里面的协议方法
//动画时间
- (NSTimeInterval)transitionDuration:(nullable id <UIViewControllerContextTransitioning>)transitionContext;
//自定义过渡动画
- (void)animateTransition:(id <UIViewControllerContextTransitioning>)transitionContext;
执行过渡动画
1.获取前后控制器
UIViewController *toVC = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
UIViewController *fromVC = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
2.获得转场动画视图
UIView *containerView = [transitionContext containerView];
3.将前后控制器需要进行动画的视图添加到containerView上
[containerView addSubview:tempView];
[containerView addSubview:toVC.view];
4.执行自己的动画

效果图：
补：
//动态添加transiationView属性 @interface UIViewController (transiationView) @property (nonatomic,strong)UIView *transiationView; @end
#import <objc/runtime.h> @implementation UIViewController (transiationView) static char transiationViewKey; - (void)setTransiationView:(UIView *)transiationView { return objc_setAssociatedObject(self, &transiationViewKey, transiationView, OBJC_ASSOCIATION_RETAIN_NONATOMIC); } - (UIView *)transiationView { return objc_getAssociatedObject(self, &transiationViewKey); } @end
