我在这里遇到了很大的问题.

我最近从Mac App Store下载了Xcode 4.3,因为它具有Lion的全屏功能.然后,我的项目停止编译.它说:

Availability.h未找到词法或预处理器问题文件.

//
// Prefix header for all source files of the 'TRGame' target in the 'TRGame' project
//

#import <Availability.h>

#ifndef __IPHONE_3_0
#warning "This project uses features only available in iPhone SDK 3.0 and later."
#endif


#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
#endif

那是在xxxx-Prefix.pch文件中.

如果我发表评论#import Availability.h,它会告诉我它找不到UIKit.h,依此类推......

帮助将非常感谢!

我正在使用此代码,其中'length'值为'50'.

newX = (arc4random()%(lenght+1)) - (lenght/2);
newY = (arc4random()%(lenght+1)) - (lenght/2);
NSLog(@"Creature Move X:%f, Y:%f", newX, newY);

但在调试器中我得到的结果如下:

2012-01-02 21:10:50.794 Kipos[28833:207] Creature Move X:4294967296.000000, Y:4294967296.000000
2012-01-02 21:10:50.896 Kipos[28833:207] Creature Move X:4294967296.000000, Y:12.000000

怎么了？

newX并且newY是浮点数:

float newX;
float newY;
