21 | ``` 22 | 最好在`- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions`里添加。 23 | 24 | 2.如果不巧的是，你的项目设置了上述两个代理（当然，大部分情况下都会设置）。不方，只要添加如下配置就好了： 25 | ``` 26 | #pragma mark - UINavigationControllerDelegate 27 | #pragma mark 自定义转场动画 28 | - (id )navigationController:(UINavigationController *)navigationController 29 | animationControllerForOperation:(UINavigationControllerOperation)operation 30 | fromViewController:(UIViewController *)fromVC 31 | toViewController:(UIViewController *)toVC 32 | { 33 | return [[FloatBallManager shared] floatBallAnimationWithOperation:operation fromViewController:fromVC toViewController:toVC]; 34 | } 35 | 36 | #pragma mark 交互式转场 37 | - (id )navigationController:(UINavigationController *)navigationController 38 | interactionControllerForAnimationController:(id ) animationController 39 | { 40 | return [[FloatBallManager shared] floatInteractionControllerForAnimationController:animationController]; 41 | } 42 | 43 | - (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated 44 | { 45 | [[FloatBallManager shared] didShowViewController:viewController navigationController:navigationController]; 46 | } 47 | ``` 48 | 49 | 更加详细的技术实现过程介绍，见[简书传送门](https://www.jianshu.com/p/d2145413db76) 50 | -------------------------------------------------------------------------------- /WeChatFloatBall.xcodeproj/project.pbxproj: -------------------------------------------------------------------------------- 1 | // !$*UTF8*$! 2 | { 3 | archiveVersion = 1;
