我正在初始化一个像这样的对象:

Project *Project = [[Project alloc] init];

这是项目类的代码:

Project.h

#import <Foundation/Foundation.h>

@interface Project : NSObject
{

}

    @property (nonatomic,assign) int projectID; 
    @property (nonatomic,strong) NSString *name; 

@end

Project.m

#import "Project.h"

@implementation Project

    @synthesize projectID, name;

@end

No visible @interface for 'Project' declares the selector 'alloc' 当我尝试初始化对象时,我收到错误.我该如何解决这个问题？
