CGRectIntersects矩形问题

我正在制作一个带有迷宫的应用程序，我在界面生成器中将一个球放在迷宫内（我为它放置了一个出口）我有一个 TouchMoved：

 -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
CGPoint point;
point = [touch locationInView:self.view];

ball.center = point;

if (CGRectIntersectsRect(ball.frame, maze.frame)) {
   //my stuff
}


   }

我有两个 CGRectIntersectsRect if 语句，我说，如果球的框架接触迷宫的框架框架，然后//我的东西发生了，但由于某种原因，每当我尝试移动球，而不接触迷宫的框架，//我的东西就会发生。我不知道为什么，也许是因为球在迷宫中，可能不是因为我说如果 cgrectintersectsrect 框架没有边界。那么为什么会发生这种情况呢？

我有另一个名为 flag 的 uiimageview iboutlet，我有相同的 cgrectintersectsrect 类型的代码，并且它在相同的 TouchMoved 中工作，那么为什么这不起作用

I am making a app with a maze, I put a ball inside the maze in the interface builder (I put an outlet for it) I have a touchesMoved:

 -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
CGPoint point;
point = [touch locationInView:self.view];

ball.center = point;

if (CGRectIntersectsRect(ball.frame, maze.frame)) {
   //my stuff
}


   }

I have two CGRectIntersectsRect if statements, I say, if the ball's frame touches the maze's frame, then // my stuff happens, but for some reason, whenever i try to move the ball, without touching the frame of the maze, // my stuff happens. I dont know why, maybe it is because the ball is IN the maze, probably not because i said if cgrectintersectsrect frame not bounds. so why is this happening?

I have another iboutlet of a uiimageview called flag, i have the same cgrectintersectsrect type of code, and it works in the same touchesMoved, so why does this not work

试试这个

UITouch *touch = [[event allTouches] anyObject];

CGPoint point;

point = [touch locationInView:self.view];


point = [[CCDirector sharedDirector] convertToGL: point];


if (CGRectIntersectsRect(ball.bounds, maze.bounds)) {


//frame - x,y,w,h

//bounds- w,h

try this one

UITouch *touch = [[event allTouches] anyObject];

CGPoint point;

point = [touch locationInView:self.view];


point = [[CCDirector sharedDirector] convertToGL: point];


if (CGRectIntersectsRect(ball.bounds, maze.bounds)) {


//frame - x,y,w,h

//bounds- w,h
