我正在加载一个菜单，其中有 7 个层，我可以在其中滑动。在第一次加载时，刷卡在 60fps 时很流畅，但是我弹出场景并再次推送它，刷卡非常慢，尽管应用程序显示 60fps，并且 ccTouchesMoved 的调用间隔与第一次加载时大致相同。
在每一层上，我添加了一些静态 CCSprite 和一个 CCMenu。
所有项目都已解除分配，我正在 ipad 3 上测试该应用程序（因此速度不是问题）。
我认为原因更多在设置部分，并希望找到解决方案。如果有帮助，这是我的触摸方法：
- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInView: [touch view]];
location = [[CCDirector sharedDirector] convertToGL:location];
//Swipe Detection Part 1
firstTouch = location;
}
-(void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
NSSet *allTouches = [event allTouches];
UITouch * touch = [[allTouches allObjects] objectAtIndex:0];
CGPoint location = [touch locationInView: [touch view]];
location = [[CCDirector sharedDirector] convertToGL:location];
CGSize winSize = [[CCDirector sharedDirector] winSize];
for(int i=0;i<[layerList count];i++)
{
[[layerList objectAtIndex:i] setPosition:CGPointMake((i-currentLayer)*winSize.width + (location.x - firstTouch.x),0) ];
}
}
-(void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
NSSet *allTouches = [event allTouches];
UITouch * touch = [[allTouches allObjects] objectAtIndex:0];
CGPoint location = [touch locationInView: [touch view]];
location = [[CCDirector sharedDirector] convertToGL:location];
//Swipe Detection Part 2
lastTouch = location;
//Swipe Detection Part 2
lastTouch = location;
//Minimum length of the swipe
float swipeLength = ccpDistance(firstTouch, lastTouch);
//Check if the swipe is a left swipe and long enough
if (firstTouch.x > lastTouch.x && swipeLength > 60) {
[self doStuffLeft];
}
else if (firstTouch.x < lastTouch.x && abs(swipeLength) > 60) {
[self doStuffRight];
}
}
