IOS开发之JSON转PLIST实例详解

 ios json转plist

  从xx.json文件中读取json数据，写入到xx.plist文件中，实现代码如下：

nsstring *path = @"/users/android_ls/desktop/city_province.json"; 
  nsarray *array = [nsjsonserialization jsonobjectwithdata:[nsdata datawithcontentsoffile:path] options:nsjsonreadingmutableleaves error:nil]; 
  [array writetofile:@"/users/android_ls/desktop/city_province.plist" atomically:yes]; 

     注：上面的代码片段必须在模拟器上运行

    若将上面的代码片段改为如下：

nsstring *path = [[nsbundle mainbundle] pathforresource:@"city_province.json" oftype:nil]; 
mylog(@"path = %@",path); 
 
nsarray *array = [nsjsonserialization jsonobjectwithdata:[nsdata datawithcontentsoffile:path] options:nsjsonreadingmutableleaves error:nil]; 
 
nsstring *newpath = [nsstring stringwithformat:@"%@%@",[[nsbundle mainbundle] bundlepath],@"/city_province.plist" ]; 
 mylog(@"newpath = %@", newpath); 
 
[array writetofile:newpath atomically:yes]; 

      注：在测试前已将city_province.json文件copy到supporting files目录下

     放在模拟器上测试，打印log如下：

2014-10-15 22:38:03.224 ywbapp[11578:60b] path = /users/android_ls/library/application support/iphone simulator/7.1/applications/0909d47b-a2b6-467d-9e19-396a73383d8a/ywbapp.app/city_province.json
2014-10-15 22:38:03.225 ywbapp[11578:60b] newpath = /users/android_ls/library/application support/iphone simulator/7.1/applications/0909d47b-a2b6-467d-9e19-396a73383d8a/ywbapp.app/city_province.plist

      放在真机上测试，打印log如下：

2014-10-15 22:40:59.796 ywbapp[3127:60b] path = /var/mobile/applications/4dab17cc-f307-4d1b-b78d-80e9b5b4343f/ywbapp.app/city_province.json
2014-10-15 22:40:59.805 ywbapp[3127:60b] newpath = /var/mobile/applications/4dab17cc-f307-4d1b-b78d-80e9b5b4343f/ywbapp.app/city_province.plist

 路径是对的，但是在相应的目录下是找不到文件的。
