使用Python腳本處理OC中的中文字符串

由於Xcode對中文支持良好，所以在開發過程中經常直接使用中文字符串。

不過蘋果推薦多語言化，需要為中文字符串添加個NSLocalizedString宏。

1. #!/usr/bin/python
2. # -*- coding: utf-8 -*-
4. '''''
5. Localization The Objective-C Code
6. @"..." --> NSLocalizedString(@"...", nil)

8. '''
10. import os, sys
11. import re
12. import codecs
14. targetPattern = re.compile('@"[^"]+"')
15. global newFile, newFilePointer
17. def isChineseCharacter(ch):
18. return 0x4e00 <= ord(ch) <= 0x9fa5
20. def hasChineseCharacter(str):
21. for char in str:
22. if isChineseCharacter(char):
23. return True
24. return False
26. def buildNewString(oldStr):
27. newStrPrefix = 'NSLocalizedString('
28. newStrSuffix = ', nil)'
29. newStr = newStrPrefix + oldStr + newStrSuffix
30. return newStr
32. def processLine(line):
33. global newFile, newFilePointer
35. matchResult = targetPattern.findall(line)
36. for result in matchResult:
37. if hasChineseCharacter(result):
38. #print result, buildNewString(result)
39. p = re.compile(result)
40. line = p.sub(buildNewString(result), line)
42. newFilePointer.write(line)
44. def processFile(filename):
45. #Xcode file is saved with utf-8
46. global newFile, newFilePointer
47. newFile = 'Replaced.' + filename
48. newFilePointer = codecs.open(newFile, 'wb', 'utf-8')
50. fp = codecs.open(filename, 'rb', 'utf-8')
51. for line in fp:
52. processLine(line)
53. fp.close()
55. newFilePointer.close()
57. oldFile = 'Old.' + filename
58. os.system('mv ' + filename + ' ' + oldFile)
59. os.system('mv ' + newFile + ' ' + filename)
60. #os.system('rm -f ' + oldFile)
62. if __name__ == "__main__":
63. if len(sys.argv) > 1:
64. output = os.popen('ls ' + sys.argv[1]).read()
65. filelist = re.split('\n', output)
66. filelist = filelist[:-1]
67. #print filelist
69. print 'Localizing...'
71. for file in filelist:
72. if os.path.exists(file):
73. try:
74. #print 'Processing File :', file
75. processFile(file)
76. except Exception as e:
77. print e
79. print 'Localization Done.'

代碼沒用經過嚴格驗證，請慎用。起碼，沒有檢查該字符串是否已經加了NSLocalizedString宏。
