问题描述
我使用下面的函数来移动屏幕上的两个按钮
+(无效)animateWithDuration:(NSTimeInterval)工期延误:(NSTimeInterval)延时选项:(UIViewAnimationOptions)选项动画:(无效(^)(无效))的动画完成:(无效(^)(BOOL完));
现在我要检测这些移动按钮的碰撞。
所以,我想知道的是有对象时动画(移动),这是被解雇的任何事件。
或者,我还有什么地方可以把我的状态
CGRectIntersectsRect(,);
解决方案
+(无效)animateWithDuration:(NSTimeInterval)工期延误:(NSTimeInterval)延时选项:(UIViewAnimationOptions)选项动画: (无效(^)(无效))动画完成:(无效(^)(BOOL完));
是射后不理式的动画。您不必访问该内部。这是自动的。
如果你需要做的碰撞检测,你可以用一个2D精灵库一样的Cocos2D或者你可以设置一个计时器,移动和手动动画按钮。
I am using the below function to move two buttons on the screen
+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished));
Now I want to detect the collision of those moving button.
So I want to know is there any event which is getting fired when the object is animating(moving).Or where else can I place my condition of
CGRectIntersectsRect(,);
解决方案
+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished));
is a "fire and forget" type animation. You don't have access to the internals. It's automatic.
If you need to do collision detection, you can use a 2D sprite library like Cocos2D or you can set up a timer to move and animate the buttons manually.
