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。
