NSBundle 的使用

    NSBundle *mainbundle=[NSBundle mainBundle];
    //使mainBundle 对象获取图片的路径
    NSString *imagePath=[mainbundle pathForResource:@"coffe" ofType:@"png"];
    //使用mainBundle 对象获取到 plist 文件的路径
    NSString *plistPath=[mainbundle pathForResource:@"testplist" ofType:@"plist"];
    //使用mainbundle 对象获取到 TXT 文件路径；
    NSString *txtPath=[mainbundle pathForResource:@"testText" ofType:@"txt"];

//处理以上路径的资源
    //imagePath
    UIImage *image=[[UIImage alloc] initWithContentsOfFile:imagePath];
    //plistPath 将plist 文件的内容读到字典中去；
    NSMutableDictionary *data=[[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];
    NSLog(@"%@",data);

    //textpath 将text 文件内容输出到字符串中
    NSString *txtcontents=[[NSString alloc] initWithContentsOfFile:txtPath encoding:NSUTF8StringEncoding error:nil];

    NSDictionary *dicAppInfo=[[NSBundle mainBundle] infoDictionary];
    NSString *AppName=[dicAppInfo objectForKey:@"CFBundleDisplayName"];
    NSString *AppVersion=[dicAppInfo objectForKey:@"CFBundleShortVersionString"];
    NSString *AppBuild=[dicAppInfo objectForKey:@"CFBundleVersion"];
    
    NSLog(@"APP应用的名称：%@",AppName);
     NSLog(@"APP应用的版本号为：%@",AppVersion);
     NSLog(@"APP应用的build版本号为：%@",AppBuild);
