1. 增加 Privacy - Camera Usage Description, value的部分寫個為何要使用的理由
2. 增加 Privacy - Photo Library Usage Description, value的部分寫個為何要使用的理由

# In model:
# include LangMapping
#
# lang_map({
#   status: [[:enabled, 1, "啟動"], [:disabled, 2, "取消"], [:unauthenticated, 0, "註冊中"]],
#   user_type: [[:standard, 0, "標準"], [:vip, 1, "高級"], [:vvip, 2, "最高級"], [:admin, 3, "管理員"]]
# })
# 會產生 class methods: all_xxxxs, instance methods: show_xxxx 2個方法
# 例如 user.show_status 會出現"啟動"、"取消"或"註冊中"
