NSBundle

bundle实际上是一个目录，其中包含了程序会使用的资源，包括：图像,声音,编译好的代码,nib文件等，cocoa中对应的类是NSBundle Carbon中对应的是CFBundleRef 

1.获取app的info.plist详细信息

版本号：Bundle version

 NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];

应用标识：Bundle identifier

NSString *bundleId = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleIdentifier"];

应用名称：Bundle display name

NSString *appName = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleDisplayName"];

Bundle name

NSString *appName = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleName"];

 

2.应用程序语言本地化

app本地化宏

#define XLocalizedString(key, comment)        [[NSBundle mainBundle] localizedStringForKey:(key) value:@"" table:nil]

中英文两个Localizable.strings文件中键值对，例如

"none" = "确定";

"none" = "none";

宏的用法：(返回NSString *)

localizedString("none", "这是注释")

 

3.获取包内文件路径和文件

获取app包路径

NSString *path = [[NSBundle mainBundle] bundlePath];

app资源目录路径

NSString *resPath = [[NSBundle mainBundle] resourcePath];

 

获取资源目录下a.bundle

NSString* path = [resPath stringByAppendingPathComponent:@"a.bundle"];NSBundle *bundle = [NSBundle bundleWithPath:path];

 

获取app包的readme.txt文件路径

NSString *path = [[NSBundle mainBundle] pathForResource:@"readme" ofType:@"txt"];

NSLog(@"ios 应用发布后 .app 应用文件 路径::%@",[NSBundle mainBundle] );
NSLog(@"ios 应用发布后 .app 应用包(文件) 的详细信息 ::%@",[[NSBundle mainBundle] infoDictionary]);
 
 [[NSBundle mainBundle] infoDictionary] 返回的是一个数据字典内容如下：
(XX1 为当前应用的名字 也就是app 包的名字 ）--（ 部分地方 XX 大写 我隐藏了部分信息...... )
 ios 应用发布后 .app 应用文件内 ::{
    CFBundleDevelopmentRegion = en;
    CFBundleDisplayName = "当前app 文件名XX1";
    CFBundleExecutable = "当前app 文件名XX1";
    CFBundleExecutablePath = "/Users/yq-010/Library/Application Support/iPhone Simulator/5.1/Applications/49419CEE-6608-48FE-81FE-BF40FEEFB8F7/XX1.app/xx1";
    CFBundleIconFiles =     (
        "icon.png",
        "icon@2x.png"
    );
    CFBundleIcons =     {
        CFBundlePrimaryIcon =         {
            CFBundleIconFiles =             (
                "icon.png",
                "icon@2x.png"
            );
            UIPrerenderedIcon = 1;
        };
    };
    CFBundleIdentifier = "com.xxxx.xxxxx";
    CFBundleInfoDictionaryVersion = "6.0";
    CFBundleInfoPlistURL = "Info.plist -- file://localhost/Users/yq-010/Library/Application%20Support/iPhone%20Simulator/5.1/Applications/49419CEE-6608-48FE-81FE-BF40FEEFB8F7/XX%20XX%20XX.app/";
    CFBundleName = "XX1";
    CFBundlePackageType = APPL;
    CFBundleShortVersionString = "1.3";
    CFBundleSignature = "????";
    CFBundleSupportedPlatforms =     (
        iPhoneSimulator
    );
    CFBundleVersion = "1.3";
    DTPlatformName = iphonesimulator;
    DTSDKName = "iphonesimulator5.1";
    LSRequiresIPhoneOS = 1;
    NSBundleInitialPath = "/Users/yq-010/Library/Application Support/iPhone Simulator/5.1/Applications/49419CEE-6608-48FE-81FE-BF40FEEFB8F7/XX1.app";
    NSBundleResolvedPath = "/Users/yq-010/Library/Application Support/iPhone Simulator/5.1/Applications/49419CEE-6608-48FE-81FE-BF40FEEFB8F7/XX1.app";
    UIDeviceFamily =     (
        1
    );
    UIPrerenderedIcon = 1;
    UIRequiredDeviceCapabilities =     (
        armv7
    );
    UISupportedInterfaceOrientations =     (
        UIInterfaceOrientationPortrait
    );
}
 
应用1：我们可以通过包的信息的数据字典 得到 应用的版本 CFBundleVersion = "1.3";
当前应用的版本 ：
[[[NSBundlemainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]]
