iOS中的NSBundle常用方法

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"];
