Read plist file during runtime

Question

I have included a plist file in my program and called it locally

     NSString *plistpath = [[NSBundle mainBundle] pathForResource:@"pli" ofType:@"plist"];
     NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:plistpath];
     NSArray *cont = [dict allValues];

I want my program to read the file when I update it manually(not by program), add or delete data from the plist file, during runtime rather than having to stop my execution and start running it again. Is there ay way i can achieve this?

Please Help

Here is the way to save your data in .plist file

NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);

// get documents path

  NSString *documentsPath = [paths objectAtIndex:0];

// get the path to our Data/plist file

 NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"myData.plist"];
                            NSError *writeError = nil;

 NSData *plistData = [NSPropertyListSerialization dataWithPropertyList:yourDictionary format:NSPropertyListXMLFormat_v1_0 options:NSPropertyListImmutable error:&writeError];

        if(plistData)
          {
             [plistData writeToFile:plistPath atomically:YES];
              NSLog(@"Data saved sucessfully");
          }
          else
          {
              NSLog(@"Error in saveData: %@", writeError.localizedDescription);

          }

Read plist from the bundle and get Root Dictionary out of it

 NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
 NSString *documentsPath = [paths objectAtIndex:0];
 NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"myData.plist"];


 if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath])
    {
      plistPath = [[NSBundle mainBundle] pathForResource:@"myData" ofType:@"plist"];
    }

 NSDictionary *resultDic = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
