我已经声明了一个常量头文件:“ Constants.h”。它包含以下声明:

extern const NSString   *Const_alertPayantMessage = @"test";
extern const NSString   *Const_alertPayantTitle   = @"Wooooops!!!";
extern const int        *Const_statutPayant       = 1;


我以这种方式使用了这些常量:

int x = 1;

    if (x == Const_statutPayant) {
        UIAlertView* mes=[[UIAlertView alloc] initWithTitle:Const_alertPayantTitle
                                                    message:Const_alertPayantMessage delegate:self cancelButtonTitle:@"Ok" otherButtonTitles: nil];

        [mes show];
        [avPlayerError play];
    }else{
        [avPlayer play];


不幸的是,我无法运行我的应用程序,因为我收到以下错误消息:

clang: error: linker command failed with exit code 1 (use -v to see invocation)


你有什么主意吗

最佳答案

“ Constants.h”应包含:

extern const NSString   *Const_alertPayantMessage;
extern const NSString   *Const_alertPayantTitle;
extern const int        Const_statutPayant;


“ Constants.m”应包含:

const NSString   *Const_alertPayantMessage = @"test";
const NSString   *Const_alertPayantTitle   = @"Wooooops!!!";
const int        Const_statutPayant       = 1;
