Xcode项目构建：失败

我正在处理简单的应用程序，并且在编写代码时没有错误，但是当我推送生成按钮时，发生错误。构建myProject：失败，xCode向我显示两条错误警告。这里的错误消息：Xcode项目构建：失败

Undefined symbols for architecture i386: 
"_OBJC_CLASS_$_AxesDrawer", referenced from: 
    objc-class-ref in AxesView.o 
ld: symbol(s) not found for architecture i386 
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我找到了，这是我Controller.m或者代码：

#import "AxesView.h" 
#import "AxesDrawer.h" 

@implementation AxesView 


- (void)drawRect:(CGRect)rect 
{ 
    CGRect b; 
    b = self.bounds; 
    CGPoint aO; 
    aO = b.origin; 
    CGFloat pPU; 
    pPU = b.size.height; 

    [AxesDrawer drawAxesInRect:(CGRect)b originAtPoint:(CGPoint)aO scale:(CGFloat)pPU]; 
} 
@end

我想在我AxesDrawer.h文件中的问题，但我不知道为什么。如果我从AxesDrawer.h更改为AxesDrawer.m（我知道这是错误的，但仅用于测试）该项目将建立并在模拟器中工作。有人可以帮助我吗？我做错了什么？

AxesDrawer.m可能不在您的目标中。点击它并使用最右侧的工具面板，并确保检查了您正在构建的目标。

你是对的，谢谢，我是iOS开发新手。谢谢。 – user748634 2012-08-05 12:54:29
