iOS 獲取版本信息之類的問題缭黔，整理一小部分
1：獲取bundle Id信息：[[NSBundle mainBundle]bundleIdentifier]；
2: 獲取App顯示名：[[[NSBundle mainBundle]infoDictionary] objectForKey:@"CFBundleDisplayName"];
3：獲取版本號：[[[NSBundle mainBundle]infoDictionary] objectForKey:@"CFBundleVersion"];
[[NSBundle mainBundle]infoDictionary] 獲得的是一個字典蒂破，里邊放著Info.plist文件中的各種信息馏谨，根據(jù)不同的鍵去即可，如：
CFBundleDevelopmentRegion
CFBundleDisplayName
CFBundleExecutable
CFBundleExecutablePath
CFBundleIdentifier
CFBundleInfoDictionaryVersion = "6.0";
CFBundleInfoPlistURL
CFBundleName
CFBundlePackageType
CFBundleShortVersionString
CFBundleSignature
CFBundleSupportedPlatforms
