iOS里APP有几种后台运行模式，例如在后台立即退出（如Cydia），在后台暂停（大部分app），在后台运行（播放音乐，广播，GPS定位等） 我搞了个切换的方法，用ssh链接到iOS设备上，传递你要更改的app的Info.plist文件就好了 程序：
#!/usr/bin/env python2.7
import plistlib as plib
import subprocess as subp
from contextlib import closing
import os, tempfile, shutil, re
from NameAppend import nameAppend
def parsePlistToString(plistFile=None):
with closing(open(plistFile, 'rb')) as pfFH:
plistString = pfFH.read()
if plistString.find('bplist') == 0:
isBinary = True
else:
isBinary = False
if isBinary is True:
out = subp.check_output('plutil.pl "{0}"'.format(plistFile), shell=True)
try:
plistTextFile = out.split('\n')[5].split(': ')[1]
if not os.path.exists(plistTextFile):
raise NameError, '{0}: no such file'.format(plistTextFile)
with closing(open(plistTextFile, 'rb')) as pfFH:
plistString = pfFH.read()
finally:
os.unlink(plistTextFile)
plistData = plib.readPlistFromString(plistString)
return plistData, isBinary
def switchMode(plistObj, mode=1, cap=4):
if mode==1:
plistObj.pop('UIBackgroundModes', None)
plistObj['UIApplicationExitsOnSuspend']=True
elif mode==2:
plistObj.pop('UIBackgroundModes', None)
plistObj.pop('UIApplicationExitsOnSuspend', None)
elif mode==3:
plistObj.pop('UIApplicationExitsOnSuspend', None)
plistObj['UIBackgroundModes']=['audio', 'continuous', 'location', 'voip'][:cap]
def main(plistFile=None, backup=True, mode=1, cap=4):
plistData, isBinary = parsePlistToString(plistFile)
switchMode(plistData, mode, cap)
tempOutFile = tempfile.NamedTemporaryFile(suffix='.plist')
try:
plib.writePlist(plistData, tempOutFile)
tempOutFile.seek(0)
if backup is True:
os.system('mv -f "{0}" "{1}"'.format(plistFile, plistFile+'.bak'))
if isBinary is True:
subp.call('plutil.pl "{0}"'.format(tempOutFile.name), shell=True, stdout=open(os.devnull, 'w'))
os.system('mv -f "{0}" "{1}"'.format(nameAppend(tempOutFile.name, '.binary'), plistFile))
else:
