更新xcode到4.5版本后我有一个错误

命令/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang失败,退出代码为1

我在更新后读到了这样的错误,但在目标的构建设置中更改架构没有帮助.它适用于模拟器但不适用于设备.

整个错误

我尝试使用以下代码在Cocos2d-x中设置应用程序中的最大FPS:

CCDirector::sharedDirector()->setAnimationInterval(1.0 / 30);

它适用于iOS,但是当我在三个Android设备上测试它时,它会被忽略,并以标准间隔(1/60)呈现帧.

如何使用cocos2d-x在Android上正确设置最大FPS？

我正在尝试使用CAlayers进行逐帧动画.我正在使用本教程http://mysterycoconut.com/blog/2011/01/cag1/进行此操作,但一切都适用于禁用ARC,当我尝试用ARC重写代码时,它可以在模拟器上完美地工作但在设备上我的访问内存不好.

Layer Class接口

#import <Foundation/Foundation.h>
#import <QuartzCore/QuartzCore.h>

@interface MCSpriteLayer : CALayer {
    unsigned int sampleIndex;
}

// SampleIndex needs to be > 0
@property (readwrite, nonatomic) unsigned int sampleIndex; 

// For use with sample rects set by the delegate
+ (id)layerWithImage:(CGImageRef)img;
- (id)initWithImage:(CGImageRef)img;

// If all samples are the same size 
+ (id)layerWithImage:(CGImageRef)img sampleSize:(CGSize)size;
- (id)initWithImage:(CGImageRef)img sampleSize:(CGSize)size;

// Use this method instead of sprite.sampleIndex to obtain the index currently displayed on screen
- (unsigned int)currentSampleIndex;
