Question

我在UISplitViewController中有一个cocos2d 2视图作为Detail View。出于某种原因，它将视图的大小调整为好像它有整个屏幕，无论是最初还是旋转屏幕时。这里有一些背景：

以下是我在模拟器中运行时的样子：

我在这个问题中解释了这个想法：UISplitViewController on iPad with Storyboards在DetailViews中创建了几个Cocos2D场景。

我更新到2.0。我的问题听起来与此类似： http://www.cocos2d-iphone.org/forum/topic/30797

Answer 1

我正在使用cocos2d v2，我不确定1.1，但在v2中，CCScene和CCLayer正在使用屏幕大小启动：

@implementation CCScene
-(id) init
{
    if( (self=[super init]) ) {
        CGSize s = [[CCDirector sharedDirector] winSize];
        self.ignoreAnchorPointForPosition = YES;
        anchorPoint_ = ccp(0.5f, 0.5f);
        [self setContentSize:s];
    }

    return self;
}
@end

...

 @implementation CCLayer

    #pragma mark Layer - Init

        -(id) init
        {
            if( (self=[super init]) ) {

                CGSize s = [[CCDirector sharedDirector] winSize];
                anchorPoint_ = ccp(0.5f, 0.5f);
                [self setContentSize:s];
                self.ignoreAnchorPointForPosition = YES;

                isTouchEnabled_ = NO;

        }

            return self;
        }

如果您想要更改它，只需将contentSize属性设置为它。

Answer 2

您是否尝试过使用一些标准的UIViews进行比较？实现相同的getRotatedBounds但没有所有Cocos2D的东西。这样你可以确定错误是在SplitViewController / Storyboards还是在你的Cocos2D处理中？

这是关于Splitviewcontrollers with Storyboards.
